Title: Canon 70D
Post by: teo770 on September 20, 2013, 03:04:17 PM
I'm considering buying one but i wonder if it ll be complicated to port ML on the 70D ?
It uses Digic 5+, is in the 60D's lineup...

Just an early opinion ?

Thank u guys !

If you're not willing to use alpha-quality software, expect about 3/4 to 1 year for a stable ml port (unless a new 70d dev pops up shouldering the burden) - currently 5d3, then 6d are in the works... so if you buy a 70d for use with Magic Lantern, either wait or think again about ff :-)

I was thinking about this camera too for videomaking.

It's the first camera with Dual AF sensor (similar to Hybrid) that allow smooth continous focus on moving objects with every canon lens.

But yestarday, while I was already putting it on chart, I sadly discovered that it doesn't allow Tv or Av selection at all  :(

Hoping to get at least that feature unblocked by ML :)

I have to correct myself.
I got the camera today,
It support Manual exposures and aperture, but only M mode. It doesn't support Tv or Av priority modes.

Anyway, so fare we're already 2 here with the reflex. Let's start taking out a memory backup for this firmware.
May I ask where do I begin?

I have a 70D and am willing to help out in anyway I am capable of. I've been a long time user of ML and would love to see it come to this camera. Any devs are welcome to contact me with instructions. My skill set it is user savvy. I have no experience with writing code but I have general knowledge of firmware read/writes, flashing/rooting phones, etc... Just trying to say that I can probably figure it out if there are clear instructions.

I just ordered a 70D and am anxious to check out its 7D-like performance and video autofocus capabilities.  I currently have a 5D Mark iii and a 60D and have been using ML for some time on both of these cameras.  If and when the developers are ready to tackle ML for the 70D, I hope they can provide audio monitoring through the A/V out port (like on the 60D).  Also, since the autofocus seems to be so fast on the 70D, another great feature would be the ability to slow down autofocus for shots where you'd want to have it look like a slow manual rack focus.

I only started using ML on my 600D a few months ago, and was gutted when I got my 70D that it isn't available yet.  So far I've only used it for bracketing for HDR, but just love it.  Guess I'll just have to make do with three exposures for now.

Thanks to all the developers - much appreciated for all the work on ML.

I think the new image sensor will make it hard for normally functional RAW Video recording. Take EOS M as an example. :)

Maybe it's not... since they use the pixel diodes for phase detection.

I also have had the 70D since it hit a select number of stores a few months now, here in NF Canada. The problem is ppl, these guys here at ML are busy, with the full frame cams and have a busy enough time with development and such that they cant keep up with updates and fimware for all the new models that pop up every 6-9 months. Patience is a virtue. I ran ML on a 60D never waited for it for my 7D and had sold it. I am on my fourth cameras in the last 3yrs. ML is GREAT! yes yet  there  will always be something better in ML but also in new development in new cameras coming out for eg. a new PANA G4, new Sony, new Olympus.

Have had one for testing for a bit, but can't let go of the T4i with ML until ML comes out for the 70D. T4i with ML is more of a camera than the 70D factory.

That's your problem right there: This level of experience won't do any good, though you can hack ml a bit for a working camera like I do.

After the first fw update (or other memory backup), to add ML to a new camera you have to have in-depth knowledge of ML and reverse engineering for the first step, then for the second step of finding the Canon fw addresses a lot of ML experience and time on your hands to do this "legwork".

Seeing how busy the experienced people here are with 5d3, 6d, 7d, eosm, ... imho don't expect ML for the 70d anytime soon unless a new experienced dev appears out of thin air. You have been warned...

i just sent my t5i back after 2 weeks to get the 70d. it was a tough decision knowing that ml isn't available for the 70d, but i got a price that was too good to pass up on.

i have development experience. i'm fluent in .net, c++, objective c. i'm learning java (for android development) as well.

i've already downloaded the dev environment so i'm ready to get cracking on this 70d port as soon as we get some fw from canon.

Theoretically it's not necessary to wait until the first fw upgrade released by Canon.
I don't remember which camera was but there was a camera dumped without Canon fw upgrade.
The program searched the IO routines in the ROM then used them to dump the ROM.
Unfortunately I've never seen the source code of this...
...and I can not sign a fw upgrade file properly for 70D but you should ask Indy who is the master of these things.
Also there is another option to dump the ROM by LED blinking... (you have to find the LED address first, and it has the same signing problem)
With the ROM dump, you can start to port ML to 70D.

I'm wondering if I should sell my 700D and work on the 70D IF you guys could make up the difference between the 700D-70D price range. That's unless some kind soul donated one to me.

I currently don't have enough to buy one myself. But I am willing to work on it.

My previous work was getting the 700D ML up to scratch with the rest, which I believe I achieved.

Almost there. In my opinion, there's a large difference from getting a port into a "seems to work" state and effectively maintaining it and fixing all those little quirks.

This is not to underestimate your work, but we have several ML ports that have not been maintained in the last few months, up to one year, so the code started to rot (I'm talking especially about 40D, 5Dc, 1100D, 6D, 7D, EOS M, and, to a lesser extent, 600D and 50D). In this situation, starting a new port doesn't seem the best thing to do right now in my opinion.

+1 ... having tweaked some small 6d parts and ported my modules from the 60d, I was surprised how many annoying little issues pop out of nowhere, costing an unbelievable amount of time even when everything seems to be in a "nearly there" state.

In this situation, starting a new port doesn't seem the best thing to do right now in my opinion.

Imho the worst thing happening to ml would be to end up with a general code degeneration, and looking at what happens when alex takes a break doesn't look promising. A lot of "wip" ports would force even cautious people to use nightly builds, and they'll attribute the resulting problems to ml in general as a "hack" and being "dangerous".

Looking at how long the 6d takes with a fair amount of work from 1%, I also think that no 70d port is better than a wip one because it'll make it clear to potential buyers that if they want ml they currently have to go for 60d, 7d, 6d or 5d3... even if I of course would be happy to see a 70d ml for their owner's sake.
Title: Re: Canon 70D
Post by: westie on December 11, 2013, 03:27:55 AM
Perhaps the older ports that are not being actively maintained should be archived (dumped) in favor of ports that are being maintained. Are people going out and buying older cameras (40D/50D, etc) to run ML? I would argue that adding the newer cameras is as important as maintaining older ports, if not more so. They are more powerful in resolution, noise, and likely processing power too - just to name a few areas.

In relation to convincing people to buy "60d, 7d, 6d or 5d3", the last 3 make sense, but are more expensive than the 70D - and two of them are full frame, which will put off people which a few EF-S lenses. The 60D is not likely to be available for long, if it is still being made, and the 7d mkI is due for replacement with it being expected in the first half of 2014.

Are there any statistics on how many people are using ML on which cameras? I doubt there is any reliable method of getting this, perhaps an option when downloading to indicate which cameras you plan to use it on? How does CHDK deal with the issue of maintaining the older cameras?

I personally own a 60D, which I use ML on, and a 70D. The 70D has fast become my favorite camera, albeit I don't have ML on it. Not everyone can justify keeping two cameras, one for ML and the other because it is better. I do have a technical background and understanding of what has been happening to get ML running, and think those out there are doing a fantastic job. I'd love to help out, but time is an issue for me, although I have looked at it a number of times.

I'd be willing to help upgrade TheUnkn0wn from a 700D to a 70D to get ML on it, knowing that it will take time to become stable. It would be interesting to know how much that is expected to cost. I've donated to this project in the past, and would be willing to do so again, but would like to know the money was going toward something that would be a benefit to me.
Title: Re: Canon 70D
Post by: ilguercio on December 11, 2013, 05:00:17 AM
Just remember that a stable and decent port requires ONE developer with that camera in their hands so they can try whatever is needed to improve the port.
The first thing that needs to be done, in my opinion, is a general agreement between the developers so they all go in the same direction as far as development and objectives.
I am pretty happy with my 6D and its ML right now altough i would love to see it a bit more stable and improved.
Like many, i do not see the point in keeping some older branches active as i would rather buy a "new" camera rather than a very old one right now (50D, 500D, 550D, 40D, 5D) .
People can't expect older cameras to have all the gizmos and stuff that newer cameras have (Canon is fast in not supporting "old" products anymore) .
Again, it seems that ML was going well in one direction and the user base and developers were in a good relation whereas now my feeling is that somebody is quite pissed, some are too demanding, some are lazy and bla bla bla.
Without pointing fingers, i would love the whole project to revive once more and pleasing us for the years to come.

To be honest, I don't think anyone is using the 6D ML anymore (same for 50D/7D/EOSM). You are running Tragic Lantern (http://www.magiclantern.fm/forum/index.php?topic=8900).

... that's why I was speaking of the 60d, but of course *used* cameras as there seem to be many available for very good prices since people moved up to full frame or 70d ... and I still think 60d+ML+ better lens(es) is a good combination vs. 70d+no ML+kit lens as the sensor didn't change a lot.

Does ML 6D even compile? Maybe 1% should rename "ML" in his fork to "TL", I'm sure he wouldn't object, it's really hard to spot the difference otherwise even if the devs might feel it's self-explanatory.
Title: Re: Canon 70D

Well, you have to admit sometimes it is hard to find the correct version to test or the exact thread in which to find information.
Yes, i am using TL right now but that's because i am not using my 6D much and TL has a few more things on it than the rest.
I am not saying that you should announce every 6D nightly as if it was breaking news but i guess i understand why some people come on the forum and are confused about what to install and who's responsible for its maintenance.

It is up to you all to find a "compromise" and try to work in the same direction.
That is what is missing, i am pretty sure you don't lack the user base, especially the professional one, to get things tested quite quickly.

In this situation, starting a new port doesn't seem the best thing to do right now in my opinion.

I can see your point of view because if I was to upgrade my 700D -> 70D then I guess there would be nobody to maintain the 700D and then that would be added to the list of dormant ports. Although, most of those cameras are old and people have upgraded to newer cameras (like the 70D) and from what I can see nobody seems to be keeping ML up to date with these new releases. Which in my opinion is a bad thing to do, since ML will be loosing out on a growing audience.

The 70D just needs lifting off the ground then new adopters/developers will maintain it. That's basically my story, bought my first DSLR (700D). Found out about ML and noticed the 700D wasn't at all up to scratch. So I got to work on it and got it to a usable state where I could use it on my trip to NY a week later.

Hello Indy.

Embedded Linux developer here, I've got a clue about what obtaining a memory dump entails, but no first hand experience on this device.
(just got this camera, would like to make some changes, not even necessarily use ML... just enhance the existing firmware)

In your experience is there a j-tag header exposed some where on the camera controller board?
Or how, in as few words as you can spare, has this been achieved in the past?

Thanks in advance

I think he is referring to the front or back focusing and general viewfinder autofocus failure that some Germans are seeing from this body. Word is that it only involves the center AF point and large apertures, but that makes no sense since the camera auto focuses at max aperture always. Not sure what's happening.

I am not seeing it on my 70D, but it's the American version.

I love my 70D it kicks ass in so many ways, but I kept my 700D for magic lantern.

Ahhh..., got it. Had that (mostly back focusing issues with non-Canon lenses) with the 60D, T3i, T4i, etc., even 7D, but at least that had MFA. I tested accuracy (as I do with all body/lens combo's now) the day I got this body. No front or back with the Canon 70-200 or the Sigma 18-35. Spot on. 70D allegedly has MFA though I've never needed it.

Not sure why a German version would be different? Should be off the same line? Feel for the folks dealing with it though, went through a lot of that with the T3i bodies...

The more I'm using the 70, the more I like, but damn..., got used to a few things that ML had for the T4i that are lacking here..

One is intervalometer function. Totally didn't think about that and went to do some time-lapse in the snow and cold... Duh. Haven't had an actual intervalometer for years now. Had it in ML for the T3, then T4i (alpha build, but even the pre-alpha I installed in the T4i worked perfect for me).

So..., damn..., do I miss ML now that I "upgraded" to the 70D...

I'm not sure if there's one or not. But I saw a guy at my local camera store. He used 5D II with a Chinese battery grip from eBay that has intervalometer with LCD screen + buttons just for $30~40. I'm finding one for my 70D right now, as ML isn't available for this beauty, the 70D.

But I'm not so sure that it can hold up to such weather... I think it will do just fine for me in where I'm living.

But I'm not so sure that it can hold up to such weather... I think it will do just fine for me in where I'm living.

Yeah, had that on the grip for the T4i, but not for the 70D. The one's I've found to be the most durable are the Meike grips (of the knock-offs) and the one for the 70D doesn't have any of those functions, just a straight Canon BG-E14 knock-off, no LCD, no timer...

Looking on Amazon, it appears that none of the grips for the 70D have the timer/LCD? Oh well...

Good idea though.

And I'm back to using my 20+ year-old USA-made CamJacket's and controlling the 70D with my cells wifi so I can close it completely up except the lens and still fully operate it/control from inside my parka and out of the wind and snow..., hah!

If I could trust leaving the cam on the tripod, I could go inside a coffee shop and control it from there. Looking for an intervalometer for Android, but no joy so far (the ones that claim to have to be tethered with a USB adapter cable).

Very bummed no support for ML on the 70D.  Just upgraded from t4i... thought i had confirmed support for 70d before I upgraded... but I must have been smoking something that day.   :-\  Anyway... interested if there is anything I can contribute.  Otherwise... I'll just be waiting patiently.

I can already see two different thread for the 70d port ..

cf : http://www.magiclantern.fm/forum/index.php?topic=6862.msg104363#msg104363

How about we merge these two so that info would not be split ?

Any updates over here about the FW dump for the 70D ?

Agree someone should merge these. I hadn't even seen that other thread till you mentioned it. No matter for me though, as much as I wish it so, no ML is being worked on for the 70D yet and playing with various show offerings coming out, there's a whole, wide world out there. Think BM cine (cheaper now with impending GH4 coming out) and the GH4. Some pretty significant changes in the wind.

Hey TomJ

How do you check focus/view display from the coffee shop?  I havent set up my 70D on wifi, but I like the idea of keeping warm.
I usually have to stop when my fingers get numb and an even greater source of shake sets in.

Same way as using Canon EOS util tethered. Thing is, from the screen of a cell, it's not so easy if you're shallow DOF focus, so I genl'y use the cell to control when I have the body remote and shooting stopped down so I have a wide focal latitude. Low-angle shots is where doing this shines. Or very high on a tripod or something.

Sorry mate, thought about it and should have given a step-by-step, sort of...

1. Download EOS Remote app and install.

2. Enable Wi-fi in camera settings.

3. Go to "Wi-fi Function" just below enable.

4. Register whatever nickname you want ("Shootme's 70D" or something like that)

5. Click "OK," then "OK" again.

6. Wi-fi function screen appears after the last OK, and touch/select "Connect to Smartphone"

7. Chose the default, "Camera access point mode" by pressing, "OK" at the bottom.

8. Chose the default, "Easy Connection" by pressing, "OK"

9. Next screen will be your "nickname" and an encryption key, that is the "password" you will enter in your phone.

Phone:

1. Ensure you have your wifi on (it doesn't need to be connected to a router, or anything, just needs to be "on.")

2. If you already have wifi passwords and routers in your phone, go into wifi, look for your camera's nickname in the phones wifi settings, select that and it will ask for a password for "shootme's 70D"

3. Enter the encryption key from the camera screen where the phone asks for password.

4. When you select, "Connect" on the phone, the camera screen should auto scroll to mac address info and such. No need for any of that, you are already (mostly) connected at this point. Now set the camera down somewhere (preferably where you can get some nice upskirts or something entertaining) in AF mode (Manual mode if you want, but lens on AF)

5. Go BACK to EOS Remote, select "Camera Connection" again and it should now show your camera's info.

6. Select, "Pairing" on that screen of your phone. It should then say, "Connected" just above the "Pairing" icon.

7. Select all the, "OK's" on the camera, hit "Menu" to exit the setup mode in the camera, and "Menu" again to exit to live-view on the camera (I turn my screen around so no one can see it if I'm shooting in public - like time-lapses of a mall or something).

8. Go "Back" on your phone to the main EOS Remote menu page and select, "Remote Shooting."

9. Tips: I use a spot-focus for most of my shooting, so I just touch the box on the phone and it corresponds to focus on the camera, whatever I tell it to focus on, yes? To change shutter, aperture, iso, just touch the corresponding icon on the lower part of the phone's screen. (example; 1/60, F1.8, ISO 640)

10. Take remote pics of pretty girls and post for all to see... (or hot dudes for the ladies here..., don't want to be sexist or anything...)

Then again, the T4i is half the price too..

Your setup is the exact as mine: 70D, Sigma 18-35 1.8. This lens is TACK sharp at 1.8 too. Stays on the body 95% of the time. Video, stills, etc.

Afaik as the ML code base is very stable by now, hard bricking is very unlikely even on new ports - and soft bricking can be avoided by not writing props to nvram in the first builds.

What will need testing (same for 6d) are the small things, does this feature work 100% or only 70% or only in some cases? Why does only model xyz show this behavior and not abc (i.e. why doesn't this key respond on 70d even if it does on 60)? This is what takes really time and systematic work from bare metal "Hello World".

My other two favs for my 70D, are the Tokina 11-16mm. When I travel I like to start off with this lens.  Get the big pictures, especially sweet for nightime neon shots. Its parfocal so good for video. Its on 10% of the time.
Second fav is the Sigma 50-150mm ( I went for the II cheaper and lighter than OS), but is very sharp, and again not bad for night time. Its on 15% of the time. Constant f/2.8. The OS is parfocal.
The 18-35mm however competes with f/1.4 glass, because it doesnt need to be stepped down to be sharp.  The smallest gripe is that its max f/16 and not f/22.  Its on 70% of the time, and is also great for macro duties in low light.
Dont forget with the 70D in video, you can use the 3X lossless zoon, that makes your 18-35mm, a 54-105mm !!! However you lose the touchscreen follow focus when its on.
Title: Re: Canon 70D
Post by: TomJ on June 12, 2014, 06:27:51 AM
Yeah, F/16 is tough, but I always carry a variable ND filter for outside, bright sun. I can still get a shallow DOF and correct exposure.

You know, I've never tried the dig zoom in video? Didn't even consider that. I'll have to play with it, thanks for the tip!!

Is there any clue on what is the max bitrate or transfer speed for the 70D already? As this is the most important spec to consider the RAW capabilities of the camera. I saw this on a website, It's sayin it can do 91mb/seg or am I wrong?

8bits = 1Byte

Let's do the math.

91/8 = 11.375

That's only 11MB/s... my brother...

(http://i1113.photobucket.com/albums/k502/darkcashyz/2014-06-13_12-26-47.jpg)

And yes, I'm curious as well. But I bet that the 70D storage interface write speed is not that great, shouldn't be better than 6D. I'll be surprised if it's any better... as I hope for that too...

Just 1080p RAW video for 20-40 seconds is more than enough for me for a camera at this price w/ Magic Lantern capabilities. That would make sick stock videos... except moire & alias thanks to Canon. :o

Hey everyone!

A (kinda) new 70D user here as well :)
My lenses are a
50 1.4
18-135 (I bought it as a kit)
and a 70-200L IS II
but I see a lot of love in the last pages for the Sigma 18-35!
 
I'm def gonna check it out, other than the obviously awesome f1.8, how does it stack up to the 18-135? I shoot weddings so I immediately see the use for a good wide angle low light lens for group shots... anybody else doing weddings with this?

My usage with video is pretty limited, can you explain how you did the following 3x lossless zoom from your below quote please?

Dont forget with the 70D in video, you can use the 3X lossless zoon, that makes your 18-35mm, a 54-105mm !!! However you lose the touchscreen follow focus when its on.

I was recently at a concert and even though I had my 70-200 with a 1.4 extender on, I could have done with some lossless zoom love! :D

Post by: ShootMeAlready on June 18, 2014, 02:57:48 PM
Most users report that only 3X is lossless, but zoom upto 5X is very usable (depending on how much up-resolution you need).  After 3X it starts into the algorithmic digital zoom.  You wanna shoot the moon?  200mm lens x1.6 crop x 3x = 960mm FF equivalent.  With a 300mm lens it becomes 1440mm ...

Ok get ready to be blown away.   You want to eliminate aliasing and moire in HD DSLR video ?
Well here is a video for the T3i, that demonstrates. 
https://www.youtube.com/watch?v=AixwZupTyeA

He uses the 3X video zoom mode to remove the moire.  Ive watched another video using a Canon 5d Mark III, that does the same thing with 5X recording (which he thinks is actually 3X, I dont own a 5DMIII so I cant tell if that is so), they claim that the 3X zoom does not skip lines, and that's how it works.

And after watching the T3i video you can be thankful that the only other Canon crop with 3X video zoom is the 70D.  3X video zoom is not a gimmick anymore.

Apparently some folks have known about this for over a year.  This link also lists some lowlight macro and tele advantages.

I just tried this with my 70d & it did help eliminate moire but the video quality looked much softer.  :(

I think the same was mentioned in the conclusion from the video:

"Conclusion:
To me, the results are great. The moire is eliminated. I know this won't work in every situation, but it is a handy trick to have available.
There are unsurprising costs. The depth of field is deeper. The image appears just a little soft with the digital zoom, albeit with decent detail -- and I might not have the focus perfect. For me, I'll trade off the moire in favor of a little softness in the image if I have no choice. The other cost isn't shown in this video, but I've seen it in other video I've shot with the 3x zoom. The noise at higher ISO's is (not surprisingly) worse in the 3x zoom mode. So, the tradeoff might not be so clear in a low-light setting, as the ISO noise might be more offensive than the moire. My guess is that this might become an issue at ISO 800+ or so. But, in daylight, is unlikely to be an issue.
... Since I already have the Tokina (and love it), I'll use it with the 3x zoom when I have to in order to eliminate moire. I will not use it to replace a 50mm otherwise, as I prefer having the sharpness and shallow depth of field option if I don't have to worry about moire."

Who would want to shoot a potential aliasing/moire subject in low light? That's kind of like shooting a polar bear in a snow storm and aiming for detail.  COMPOSITION is sometimes is influenced by common sense.

The other video using 5D MkIII, noticed less contrast in 3X shots. That's something which can be addressed by changing your exposure or shooting RAW and address in post.  Its not a perfect solution, but if handled correctly a livable one.

Perhaps if you add a bit of hard lighting, it will increase the contrast as well?  Hmmm ...

Back in the early '90s a few camcorders featured a digital 16x9 mode that did create the intended 4x3 squeezed video that needed a 16x9 TV to be view correctly. Everything looked skinny until the 16x9 TV "unsqueezed" the video to look normal. Because the video was created digitally, not optically, digital sharpness increased in this mode as well. So, the results was an over-sharpened, color faded, soft looking video. It was a failed experiment at best. This was also my impression when recording @ 3x in the 70d. Nice to know the camera will do this. Maybe some will use it but doubt if I ever will.

The 3X is not a digital manipulation. Its lossless and from my observations sharp. However all my zoom lens have softer contrast and colour at their farthest reach/zoom.  When you zoom, you also get less light on the sensor.  So unless you collect more light (some how?) when you zoom, it must be softer.  The 3X zoom pic. should be softer than one taken from a prime of the equivalent focal length.

I thought a bit more about this. The 3X zoom, really turns the APS-C sensor, into a 1/3 Aps-C sensor.  So even though its sharp, the light collected is on a smaller sensor portion.  Well we all know that smaller sensors have less intense colour/contrast and handle low light worse increasing noise.  So the 3X zoom, keeps the same number of pixels but now its over a smaller sensor.  So with less sensor it has to be softer.

My 1st impression of the overall results, however IMHO, do look soft, less contrast & weak color. I believe your "...1/3 Aps-C sensor..." assessment is correct. This would explain the "soft look", etc. I will experiment with 3x a bit more.

I believe your "...1/3 Aps-C sensor..." assessment is correct. This would explain the "soft look", etc. I will experiment with 3x a bit more.
The more I think about this question, the more I think I get what's going on.  I think in normal mode, the processor is basically skipping or selectively using lines. Why you ask does it skip any lines? I think with the higher receptor density on the sensor, in order to minimize noise effects the processor skips lines (hence the true source of moire /aliasing is this skipping).
This explains why smaller sensor portion handles low light worse (its not just a crop of same lines, its using adjacent lines with more noise).   More noise also explains weaker colour / contrasts. 
The processor in normal mode probably cant process all the lines as input anyways (hmmm ... always seemed RAW video limits is most hampered by the weak processor), so aliasing and moire may also be there due to processor limits as well.
Having skipped lines, probably also reduces noise on the luminance/colour receptors, so better contrast / colour.

That's the trade off, less moire / aliasing with a softer picture (more noise) or better contrast/colour (less noise) with aliasing /moire.  Neither is perfect solution, knowledge is power ... It seems a low moire / aliasing shot should be done with ISO 100.     Add whatever lighting / ND filtering to stay at ISO 100 to get the least noise and best picture.  That's my humble suggestion - Gaross try a 3X zoom clip at ISO 100 with proper exposure on a decent prime lens and see if it removes the aliasing /moire and the softness?     

BTW it seems if the camera processor was 3X more powerful, then regular mode should use every line, and then it should be the same as 3X zoom mode.  And to improve noise even more you need a 3X bigger sensor, so the adjacent lines are further apart.

3x does what it says it does... but at the expense of video quality. I did a few test over the weekend & got a lot of moire while recording video of a nearby home's vinyl siding in standard 24P & 30P. I had the zoom set to approx 50 - 60mm for the standard test, then set it @ 18mm @ 3x. The frames matched fairly close. True, moire was reduced but at the expense of video quality. I prefer moire over poor PQ. It's an interesting feature but not one I'd likely use.  :o
Title: Re: Canon 70D
Post by: ShootMeAlready on July 02, 2014, 05:40:16 AM
I did some of my own 3X tests.  I first shot 50mm f2.8, in low light, and found great colour, no CA, but aliasing and moire observed on some clips.
I went out another night, used my Canon 85mm f1.8, ISO 100-400.  I tried the 3X zoom, shooting taxis & streetcars in low light. 
I found the CA purple fringing was horrible on the car and taxi headlights for 3X. The 3X amplifys the CA!  Apparently this is pretty common, even wikipedia states CA occurs with lens wide open in high contrast.  I have shot a lot of neon lights at night using f2.8 on my Tokina, so I know the fix.  Again it comes down to knowing your gear, and how to tweak it to get the best shot.
1. Aliasing / moire use 3X zoom, at ISO 100.  Bump the contrast & saturation & vibrance up in post. I always shoot video with lowest contrast and slight desaturation then add back in post.  However There is no easy post production fix for aliasing /moire once its in the footage.
2. High contrast avoid CA by using f2.8 or higher.  Bump up the exposure +1 or so in post.  Post production After effects "Change to Colour" removes it.

Apparently, 3x is for special needs. As your tests indicate, much preparation is needed in order to get a clean shot. It's results are very conditional - some good, some bad. I guess if you practice enough you can adjust quickly & obtain good footage; especially where moire conditions will be high.

Another Question about video shooting with the 70D: What picture style are you using? Or don't you use picture styles?
Big topic you ask (ok Ill stop the Yoda speak).  My HDDSLR guru says to use a custom picture.  Contrast = 0. Slight desaturation (-2 or so).  Sharpness = 0.
This is for MOV shooting which is ETTL (expose to the left).  MOV is like jpeg in that, once you have a blown highlight detail is gone and can not be recovered in post.
This is true for any colour histogram.  So you want a margin of error, hence expose to left of zero.  Add contrast and colour/saturation with the software (not the camera).
Heres a link to my guru:  https://www.youtube.com/watch?v=FPIOPc71REY
If you subscribe to the channel and watch all the video, you too can talk with a cool German accent and be a fount of wisdom. I think of him as my DSLR video mechanic.

If we ever get 70D with ML, then this is thrown out the window, because shooting movie in RAW means ETTR (expose to the right).  One would probably adjust the pic style to flat/neutral then shoot ETTR (1/3 stop or so) to max. the captured colour/contrast bandwidth.  This means more detail to work with.

Sadly, it's too heavy. My 70D is like car's equipment now. It stays within a car and doesn't go anywhere(well, it did once in this vacation, and it went back to the bag within 10 minutes due to its weight/my effort). So I decided and took shots with the S5 since the quality is quite OK for life logging and it goes underwater. I only use DSLR when needed...lately...

And yes, the 70D body itself is great. I barely have use manual focus in video. It's worth an upgrade from my previous 60D.

Excuse my shooting and editing. I have no idea about color correcting. haha (The video is in Thai)

This camera is already something without ML. With ML, it would be something greater. Many ML features in 60D and EOS M had helped me in many situations. I just wish EOS M II had the same sensor as 70D's or at least the same liveview auto-focus capability. So I can always bring one plus 22mm f/2 with myself for any vacation.

I was wondering about the max. write speed of the 70D.  I need some faster SDHC cards, as I am learning to shoot Dual ISO RAW on my T3i/600D. 
And as such I would like to ensure I get a write speed suitable for the 70D in raw Dual ISO.  As far as I can find the fastest SDHC is something like 95MB/s read and 90MB/s write.  I am wondering if there is any good campare point for the 70D to an existing ML Dual ISO running camera with Digic 5 processor and 7fps shooting?

Answers: Ok read earlier threads looks like 45MB/s write, which suggests 720p raw max. res. 
The SDXC is faster bus, perhaps runs faster than SDHC of same write speed.
6d is closest cpu and write speed comparison for 70D. Nice chart
https://docs.google.com/spreadsheet/ccc?key=0AgQ2MOkAZTFHdFFIcFp1d0R5TzVPTVJXOEVyUndteGc#gid=5
Now the faster cards would help with -
Dual ISO raw provides 14 ev, which may yield better results than 720p raw.
Slower FPS video, with Twixter interpolation in AE, allows highest raw resolutions at 24fps. But I am not clear how well Twixter interpolates missing frames when theres motion??? hmm.

For me, the first thing to check is the card.   Is it close to full? writes slow down when its close to full (5% or less free).  What's its write speed?  I have been using a 20 mb/s write speed video 24fps FHD without issue.  And its the write speed that matters, most cards advertise the read speed.  Amazon had some nice prices on Sandisks Extreme Pro UHS-I 95mb/s read, 90 mb/s write.

Got a fist full of Sony 32gb class 10 cards a while back that I use. 94mb/s read, 45mb/s write.

But being full might just have been it. Was also shooting at 24fps FHD, but card filled and had to swap out, I remember that. Just as I was finishing an event. Might have been that. Thanks for the tip, never had issue with that before (losing data as a card filled), but I'll test it out and make sure I swap cards at an opportune time (as I usually do when covering an event that I can't make-up).

I have only had the "near full" scenario happen on my T3i with ML with a 16GB slower card.  Strange things happened as it over-wrote some of ML, and my display went foobar, and it noticeably slowed down.  There was some free space when I checked in Windows on the card but less than 5%.  Never tried it with the 70D, but with lots of video strange things could happen, but even if it just slows down that alone would drop frames.

Post by: ShootMeAlready on August 04, 2014, 10:49:10 PM
OK, so I have done quite a bit of testing with my 600D/T3i in raw.  Based on my testing I can start to project what to expect from the 70D raw (assuming some dev can deliver such a build for our humble testing).  Certainly the continuous focus is the main draw (for now and in this snack bracket). Firstly lets deal with the pretenders, the Black Magic pocket camera, the sensor is smaller (3/4) and it has 12 bit colour depth. If you compare to 12 bit depth and bigger aps-c sensor (I realize this is new ground for aps-c users who keep getting put in our IQ place by FF users) then you realize size and depth both matter.  Personally I would rather buy a used 50D and shoot in 14bit raw with dual iso, then a 12 bit Black magic 3/4 sensor anything camera.  I mean if you are going to wait that long to process your film then why stop at 12 bit blah!I think some H264/MOv of the 70D can match 12 bit raw blah adequately.  Its in the physics 14bits beats 12bits, so sorry BMPC users suck it up.

So lets cut to the chase, the bottle neck on the 70D in raw is the SD card write speed, which is 40-45 mb/s.   This is the albatross we have to deal with.
This is what I learned from my 600D/T3i:
1. Anamorphic means higher resolution than 16:9.  If you want to shoot a film, then 2.39 aspect ratio is your friend. I am not sure what the highest ratio for the 70D will be, but I can tell you that with the 600Dat half the SD write speed, it can go 1142x482, which is 80% of 720p anamorphic.
2. With a SD write speed of 40-45mb/s, your best option for 16:9 aspect is 720p (1280x720). Compare to the 650D which has the same SD controller speed.  The 650D supports continuous 720P HDDVD  at 24 fps (cinematic quality). That's what to expect with the 70D.
3. Now lets say, you want to use the awesome continuous focus of the 70D at some high frame rate or 1080p res., then you may think that based upon a slow SD write speed, you are SOL.  Well if you have a shot that is slow camera movement and slow motion (OK I mean an establishing shot), then you can shoot raw at higher res. with a slower frame rate (on my 600D I was able to shoot 1600x670 at 12fps), perhaps even 1080p anamorphic ??? (I am not sure what's the limit but with anamorphic you have a great chance to get to max. res.), then in post interpolate frames to add the missing frames.  As long as your shot is slow camera movement and slow motion this will work (Ok so lets just say real estate videos of properties are in the bag).
 
PS: Did I mention that dual iso (11EV) 14 bit raw blows the snot out of a Black magic pocket camera 12 bit raw with a teeny-weeny sensor ... So if you shoot dual iso raw be prepare to be gob-stopped.

Correction:  Use the right tool for the right job.  Up to 14EV shooting video 14bit RAW can be had for 43rds, aps-c, or  FF cameras, so its not a limiting factor.
43rds provides super 16mm DOF / look.  Useful for run & gun documentary style.  Its superior sharpness /deep DOF good for landscapes with detail.  Its common 4K resolution is good for cropped shooting (i.e. action scenes shot wide then cropped in post).
APS-C is best choice for the Super 35mm look of classic film. Also a good choice for wildlife and sports shooters stills, as the aps-c 1.6X added reach, saves huge $$$ on telephoto zooms and much lighter/smaller lenses help out in the field.
FF is best choice for stills with shallow DOF, and low-light. Its use in video permits low light shooting, shallow DOF, wider FOV for an "anamorphic like effect" all creative tools permitting a different look than the classic 35mm look.

You say:
"So lets cut to the chase, the bottle neck on the 70D in raw is the SD card write speed, which is 40-45 mb/s.   This is the albatross we have to deal with."

Perhaps i missed something, but i never seen this limit concerning 70d, processor has changed from 650d, 700d, 60d, so the limit could be the write speed from the card, not from the 70d itself.  Some SD cards are now able to write at 90 MB/s and this could be an interesting improvment.

Post by: X-STATE on August 05, 2014, 01:53:04 PM
The processor (DIGIC) has nothing to do with it. It's the card interface.
As of today there are 2 speed limits detected (SD-card): Low end with about 21 MByte/s when writing. High end with about 41 MByte/s.

5D3's sd card interface is limited to 21 MByte. DIGIC 5+ doesn't help here ...
Walter, as I remember, you have contacts with the developers :) Do you have any news about the status of the port on the ML 70D?
Title: Re: Canon 70D
Post by: X-STATE on August 05, 2014, 03:51:55 PM
Yes. I post messages here and sometimes there is some interaction between some guy who happens to be a developer and me.
Why don't you send a message to Nanomad and ask for yourself? But I have the vague recollection about Nanomad taking some time off. I hope he is enjoying it and it's not because of work/study/... related priority stuff.

Ciao

So I do not ask to Nanomad he dropped everything and worked only port. :) I just thought that maybe you have some information  ;)

Post by: Jackeatley on August 11, 2014, 06:19:11 AM
OK, so I have done quite a bit of testing with my 600D/T3i in raw.  Based on my testing I can start to project what to expect from the 70D raw (assuming some dev can deliver such a build for our humble testing).  Certainly the continuous focus is the main draw (for now and in this snack bracket). Firstly lets deal with the pretenders, the Black Magic pocket camera, the sensor is smaller (3/4) and it has 12 bit colour depth. If you compare to 12 bit depth and bigger aps-c sensor (I realize this is new ground for aps-c users who keep getting put in our IQ place by FF users) then you realize size and depth both matter.  Personally I would rather buy a used 50D and shoot in 14bit raw with dual iso, then a 12 bit Black magic 3/4 sensor anything camera.  I mean if you are going to wait that long to process your film then why stop at 12 bit blah!I think some H264/MOv of the 70D can match 12 bit raw blah adequately.  Its in the physics 14bits beats 12bits, so sorry BMPC users suck it up.

So lets cut to the chase, the bottle neck on the 70D in raw is the SD card write speed, which is 40-45 mb/s.   This is the albatross we have to deal with.
This is what I learned from my 600D/T3i:
1. Anamorphic means higher resolution than 16:9.  If you want to shoot a film, then 2.39 aspect ratio is your friend. I am not sure what the highest ratio for the 70D will be, but I can tell you that with the 600Dat half the SD write speed, it can go 1142x482, which is 80% of 720p anamorphic.
2. With a SD write speed of 40-45mb/s, your best option for 16:9 aspect is 720p (1280x720). Compare to the 650D which has the same SD controller speed.  The 650D supports continuous 720P HDDVD  at 24 fps (cinematic quality). That's what to expect with the 70D.
3. Now lets say, you want to use the awesome continuous focus of the 70D at some high frame rate or 1080p res., then you may think that based upon a slow SD write speed, you are SOL.  Well if you have a shot that is slow camera movement and slow motion (OK I mean an establishing shot), then you can shoot raw at higher res. with a slower frame rate (on my 600D I was able to shoot 1600x670 at 12fps), perhaps even 1080p anamorphic ???

Yeah yeah.... The blackmagic is producing 12 bit log, the canons produce 14bit Lin.  When you put that blackmagic footage back into resolve it "unpacks" to 16 bit lin. Therefore making it better...

It also has a super 16 sensor. Which is a long established cinema format with a wide range of glass.

The 50d also does not support dual ISO video.

It also in its aps-c mode us limited to around 1500px rather than the 1920 the blackmagic produces.

So all in all a pretty sill argument you made.

Does this mean that you have dual iso working already on the 70D? If so, how does it work? per "dual pixel" line (so the two photosites under the same microlens are binned and thus it works like on previous cameras) or can you actually read the two photosites under a microlens individually and apply different gains to them?

I own a BMPCC and a 50D and I'm calling you out on this post:

- The sensors in the BMD cameras are 16-bit. The hardware in them encodes that 16-bit linear signal into a 12-bit log CinemaDNG, which maintains all the information through the post chain. It works seamlessly and provides just as much information as MLV 14-bit, if not more.

- BMD cameras use the entire sensor rather than line skipping or pixel binning, which means you get a really accurate image at the full resolution of the sensor. I'd put a BMPCC against a 5D Mk.3 in resolved detail any day and I think you'd be surprised at how well the BMPCC performs.

- What's wrong with smaller sensors again? There are wide angle lenses for the Micro4/3 mount, the glass is fast and sharp, and the MetaBones Speedbooster gives you a ridiculous amount of options. Besides, the Super16 image circle has a long and storied history in cinema and creates beautiful images.

- Dual ISO is a great idea, no doubt about it, but there are very real tradeoffs with high frequency detail in your images. It's good to have in an emergency but I couldn't see myself using it unless I had no other option. It's also only available on two cameras as far as I know (the 5D Mk.3 and 7D).

- The BMD cameras are a stable, proven platform to work with in a production setting. With all due respect to all Magic Lantern developers, ML is experimental. The BMD cameras aren't perfect but when I use them I know I am using a camera that was explicitly designed to record RAW footage for motion picture cinematography. It shows in the workflow, the stability of the software, and the camera interface design.

Once you get some more experience under your belt I'm sure you'll realize that cameras are tools and this whole dick-waving competition is pointless.

I have tested on the T3i/600D, in mov, raw, and dual iso raw.  It is not working on the 70D yet, but the SD controller write speeds are similar to the 650D, so one can expect 40-45 mb/s.  That means to expect continuous 720p raw (16:9).  It is likely that anamorphic (2.39) will be very close to 1080p. Would love to find out what the 650D max. pixels for continuous anamorphic @ 2.39???.  My observations are that raw beats mov, especially in lower light (everything else being equal).  Dual iso raw beats raw by about 11ev on my T3i (its some what like having a bigger sensor, in that it handles lower light better  yielding richer luminance depth).  The dual iso raw workflow, is one extra process on the DNG pics.  It takes the dual iso values (100/1600 etc.), and combines both (need to check raw dual iso threads for the details of how it works).  I have tried HDR video, and its more finicky, and does not handle fast movement (adds blur) so its only good for slow moving master shots.  The dual iso, however handles motion no problem.   The one area the dual iso raw is weak from what I tested was moving high contrast edges/lines (some moire on the fringes, we are talking  bright white shirt against dark black background in motion), suggest its best to shoot those in vanilla raw or perhaps 3X zoom mode ... hmmm.

I think this is poor etiquette on the developers part especially considering the 70d was funded by the community. Not pressuring the dev for an ETA just asking him to pop in here and give us some form of update and whether or not he thinks the RAW port is possible and if he has taken up the coding offers of help from this thread.
The current route of a complete communication blackout is not helpful. Personally I am only holding onto my 70d in the hope of gaining some form of RAW recording support. If this is not possible or the current developer is not continuing with the process then I would like to know as I will sell my 70d now as technology depriciates in value in light of new releases.

The matter of ETA is covered in ML's FAQ: When it is ready!
You have two options (at least): Wait for something to come without the last chance to get an ETA. May come soon, later or not.
Or go for something offering the options you want to have.

PS: Did I mention that dual iso (11EV) 14 bit raw blows the snot out of a Black magic pocket camera 10 bit raw with a teeny-weeny sensor ... So if you shoot dual iso raw be prepare to be gob-stopped.

So I wanted to correct my post.  I looked a lot more into the 10bit raw vs 14bit raw, and have to admit that after the compression is taken into consideration, that its not the issue.
For those who wish to read about sensor size, and its impact here are some links & key points.
Here are some crop ratios:  5D MkIII  FF sensor crop 1.0,  70D APS-C crop 1.6, BMD CC crop 3.02.  The difference in the the BMPCC is about the same difference as an APS-C is to a FF.
So what does that mean, here is a highly technical university of chicago paper analysis.  For those who are not inclined to scientific papers, just go the end and read his Bottom Line conclusion.
 http://theory.uchicago.edu/~ejm/pix/20d/tests/noise/noise-p3.html#bitdepth~  The bottom line finding:
- "bigger sensors yield higher quality images, by capturing more signal (photons)."  Of course Ive watched many FF vs APS-C video comparisons which illustrate this finding.
- He also mentioned that larger sensors capture more image in lower light (but again anyone of a 100 videos on the subject demonstrate this).
A few more well known points gleaned from Wikipedia (included as a nominal reference). http://en.wikipedia.org/wiki/Image_sensor_format
- increased noise SNR (proportional to square of crop factor), which is a bad thing.
- diffraction impacts sharpness, which increases with smaller sensors, which is a bad thing.
Now lets look at a rather interesting comparison done by Blunty (an Aussie photo blogger), comparing the BMD (the Aussie company). Surely if anyone was to be bias Blunty should be.
Blunty Compares 70D with BMPC -   https://www.youtube.com/watch?v=JAIF5Q5tPAQ
- What I see in every shot of the BMPCC is that its washed out colour depth compared to all the other APS-C cameras including the 70D.  No surprise the science suggests that.
- The BMPC handled detail in the shadows, that was its main advantage, perhaps due to raw vs H264? Not quite sure to be honest (????).
Another video, BMPCC vs 60D - http://vimeo.com/80026804
- This uses a 60D its not a bad 70D comparison point.  The BMPCC has very washed out colour, flatter pic, and lower sharpness (again agrees with the science).

SpeedBooster - for BMPC
- This is rather fabulous enhancement for the BMPC.  Prices around $660USD, was what I saw, and provides a 1.75 crop but it does not increase the sensor size.  Its pretty much essential for BMPC.
- It improves the lens list and provides awesome fast apertures.  These create a niche where the BMPCC has some of the fastest aperture glass !!! (turns a sigma f/1.8 18-35mm zoom lens into f/1.0).  It WINS in this aspect.
- However wonderful the low light glass ability, the colour depth and image quality is still constrained by a small sensor.  Scooped from a pro blog, 
One has to to shoot using the waveform, with everything "over exposed" and pull back in production. Need an external monitor one on back not useful.
"You have to get every photon on sensor you can".  Life is not good in this aspect. 
- PS: Strange thing about the BMPC is that BMD dont provide a Canon lens list, and when you read through the blogs you keep finding one saying yeah a lens works and others finding well not in every aspect
on many lenses so its never clear what glass fully works???

Correction: GH4 is better than BMPC.  If you want to shoot super 16mm digital equivalent, with extra goodies like 4K picture, and FHD 60fps its an affordable choice. Run & gun documentary style its a great choice.

"Did I mention that dual iso (11EV) 14 bit raw blows the snot out of a Black magic pocket camera 10 bit raw with a teeny-weeny sensor ... So if you shoot dual iso raw be prepare to be gob-stopped."
- Well it turns out that the 50D, which can be had for about $500USD, has 11EV of dynamic range from dual iso in raw, and combined it tends to blow the ... well you know. 
Lets see, bigger sensor and 11EV more dynamic range (which makes an APS-C seem closer to a FF),  all for less than a quarter of the money of a BMPCC+speedbooster+monitor+rig (yeah it needs a rig!).
... hmmm tough choice.  And a 70D with dual iso raw [email protected] (when it arrives), auto-focus, with 3X lossless zoom for anti-aliasing, even better still for film ... 


Still doesn't change the fact that the 50d can't do dual iso video, its a dead horse point.

The smaller sensors have advantages too, they increase depth of field making critical focus easier, they also tend to make everything look sharper for that reason, which is why all the blackmagic pocket vs other things look sharp because they haven't compensated for the DOF change.
Title: Re: Canon 70D
Post by: ShootMeAlready on August 19, 2014, 09:58:09 PM
Interesting point on the sharpness of smaller sensors being better suited for critical focus (any references on that? its interesting).  But the part that confuses me on that is why FF can out sharpen aps-c often ?(except for the sigma 18-35 f/1.8 comparisons which is because of the superior glass).

I dont own a 50D.  But from what I read it was one of the first to offer dual ISO.  Here is one video where he used 50D for dual iso raw  http://vimeo.com/73732208
I like dual iso raw for smaller sensors because it gets a richer luminance, and starts to recover detail in shadows.  Its a much better comparison to the BMPCC raw.
However before one gets hooked into thinking everything must be dual iso raw, let me say that its a whole lot easier with vanilla raw.  Not every shot will benefit from dual ISO.
I think the true champ for aps-c raw is the 7D (near 1080p continuous), but its still a rather expensive camera especially if you already have invested in a 70D.
When I have the extra cash lying around, then I would go for a 7D over a 50D.  Until then I will explore raw and ML with my 600d.
However if you were buying right now and wanted a B cam that utilises aps-c glass and does raw, the 50D is best bang for the buck.
 
 
Correction: for 7D & 50D dual ISO is still pics only sadly not video ...
Dont think I would buy a 7D for raw, as its rather expensive for what you get. D50 best aps-c raw bang for buck.
5D MarkII used, is better buy than a 7Dfor raw, and slightly out performs for about same money used. 
5D MarkII is FF, so you have to consider your lens costs to cover your FF lengths.

Depends on what your output is used for. We had a 7D and went to the T3i (cheap and had ML at the time), then T4i (for AF and ML capability + articulating screen for use where you do NOT want to put it up to your face).

If all you care about is RAW, then perhaps the 7D. But you'll take a LONG step back in AF capability for video. ML will be out soon for the 70D and you have ltd RAW output.

Its hard to know what is perfect for you as these decisions revolve around budget.  If you like DSLR and not BMCC ($3K)to shoot raw then the champ is the 5D MIII ($3.3k), it has the biggest sensor shoots raw that is motion picture quality, but its glass (3 f/2.8 zooms, and 4 primes) run around $8K.  Then the second question is do you want to pull focus? If that's your thing then a 70D is not a help.  The setup that some like is the 5DMIII to shoot raw, and the 70D for its continuous auto focus.  So for a raw shooter the 70D is a B cam, used for certain shots (ETTL and color graded to match).  I think there is no decent replacement in video for the 70D, unless you like to pull focus manaully. Now if the 5D is to rich for your blood, then the best aps-c glass raw resolution is the 7D (used about $750) it has some banding issues which limits your ISO (meaning very low light is more challenging, but some claim the post software can fix it?).  Now if that's too steep there is the 50D ($500 used) its a great picture but no audio so that its own issue.  As for VAF you will need that for all canon DSLRs except perhaps the 5DMIII, and the T3i/600d and the 70D (which have 3X zoom mode which removes aliasing).  So look at budget and focus pulling ability before you decide on the 70D.  As for 70D raw, well that may not be for a year (its not for sure).

Thanks! I understand the point. I'm using manual focus lenses, ver old ones and I'm not really interested in automated focusing. With ML Raw the 7D can do better resolution videos than the 70D would with its around 40Mb/s... so, the last point would be the image qualty, noise and how both cameras work in low light situation, wich I think they do almost the same as I far as I have seen on youtube videos...

I offered to do it myself or at least to act as an escrow if someone else wants to do it. Si far no one has replied to my request to send me a PM if willing to contribute. I do restate my offer though.

I have just pm'd nanomad that I stand by my offer to contribute 1/3 of the cost of a 70D body. I invite you guys to join!

I understand there can be no guarantees, but that's life. If you want this to happen, sharing in a minor portion of the cost is the least you can do. Most of the resources will come from nanomad anyways, via his time and opportunity cost to take on this project.

Greetings to all of you. I helped kick off the donation and came through with a third of the cost.

You know that I know there were no guarantees as to the outcome of the port.

Some info now and then I would appreciate though.

Cheers
Philipp

Philipp,

As a contributor who put his money where his mouth is and helped us all, first, thank you for what you did. It (hopefully) furthered the development of ML for the 70D immensely.

Second, that is reasonable to want to hear something about development, where things stand, what the road blocks are, etc.

I know it's a long shot.. but I just purchased the 70D but the one thing that I found annoying was that it can't record 1080p at 60fps yet surely this camera is more than powerful enough to support it right?

Could 1080p 60fps support be added in a future official firmware update or possibly added with ML?

Just ordered my first semi-pro cam ever.... The Canon EOS70d

The choice stood between the 70D or the Lumix GH4.. My main use for the camera is to record my band while playing gigs. I already have the tascam dr60 mobile recorder and awesome mics to go with it.

I would really have liked the 4k video on the Lumix, but after searching a bit and wavering between them it came down to difference in price, filesizes for the 4k and wanting to have a camera which also will take good stills (which I'm sure the Lumix also does) But the better AF, bigger sensor and lower price on the 70D made me go with that one....

Now, the one and only thing I really need (which goes for them both) is to go beyond the 30 min recording time (Because of the lame EU law) since I sometimes will set it up and start record and then I go on stage and play, and we play for like 50-60 minutes which mean I wont get the whole thing recording... Again, lame EU law...

so a ML with the recording time limit removed for the EOS 70D would be insanely much appreciated... :-)

Canon 70d has faster autofocus for video and is better all around for photo. But, considering all the video attributes of the GH4, I'd give it serious consideration over the 70d. The video quality comparisons I've seen of the GH4 make it more inline with Canon 5d Mk III. Add the fact that the GH4 can do 4k now & who knows if the 70d will ever be able to, may be the deciding factor. Good luck!

Canon 70D è dotata di autofocus più veloce per il video ed è meglio tutto intorno per la foto. Ma, considerando tutti gli attributi video della GH4, darei seria considerazione sulla 70D. I paragoni di qualità di video che ho visto del GH4 rendono più in linea con la Canon 5D Mk III. Aggiungete il fatto che il GH4 può fare 4k ora e chissà se la 70d sarà mai in grado di, può essere il fattore decisivo. Buona fortuna!

 from having the 60d and going to the 70d is awesome.
such a better camera all around.
 I too try to offer support for ML (and specifically the 70d) but don't seem to be able to (easily) locate the page(s) or how to help out.

 is there a (simple) place or location where there is a list of people to contact and work with towards helping ML (even if its the man pages)?

Well, sad to see that this is holding up dev, but I have the same things going on in my life and it suddenly made me realize that the dev's also have lives, ups, downs, good, bad, not just sitting with a camera, cable and computer day after day, night after night.

Had a chance to buy a 7DII, but after seeing that they STILL haven't gotten around to an articulating screen (that I've found I can't live without these days), I'm sticking with the 70D. Maybe not be as tough, but it has what I need for the jobs I do. The 7DII, well, it doesn't. So to me, the "pro" camera is the one that gives me saleable output. The 70D does that, the 7DII would not (at least for a lot of the kind of shooting I do). So for me, the 70D IS the "pro" camera. Still.
Title: Re: Canon 70D
Post by: ShootMeAlready on September 16, 2014, 04:31:13 AM
Have to agree life sometimes gets in the way ... life is what happens to you while you are busy making plans ... John Lennon.
The 7DII has some awesome features for birders & sports shooters.  For still shooters the 65 focus pts, and 10 pps is excellent. Aps-c with the 1.6X for birders and sports shooters helps. But if you want it to shoot video it comes up short.

According to an emmy award winning director of photography the number one thing is focus, and the 70D trounces all others as its the next best to having a Hollywood focus puller.
Well without the touch-screen, youve lost your focus puller (unless you are really handy with dials when shooting video).!!!  This does not replace my 70D period (it loses right there).  The 70D articulating screen, is very good when not using a tripod, overhead shooting, and angled in sunlight still permitting touch screen follow focus.  Putting a 3X hood on the 7D makes sense it will help manual focus and sunlight shoots but that setup is not as versatile as an articulating touch screen.
It seems the 7DII's use of AF is really about tracking for still shooting subjects before you click.

The same emmy award winner picked low light performance as number #2 importance.  The 7DII sensor has not been put through its paces but I would be very surprised if it rivaled the 5DMII/III which the same director picked as HDSLR standard low light performer.

For video the 7DII uncompressed HDMI 4:4:2 8 bit FHD from the usb port is rather sweet as you could stream live to a lap-top (for a studio/tripod setting that's nice - get 8 of these and you can live monitor/stream a hockey game).  Although everyone wants to monitor audio, I did not read about XLR input so its not going to be used for quality audio recording just monitoring.  The slo-mo 60P FHD is another video advantage.  Its certainly useful for video but it does not replace the 70D's fast continuous AF on moving subjects for video.

I keep reading up on the GH4, the camera of 2014 so far, but it seems from the blogs and clips, no one can get decent cinematic skin tones, its challenged in low light & in artistic bokeh, and I keep bitching about the harsh/washed out colour tones I see in all clips due to MFT sensor size.  However for run & gun documentary style its light weight and a interesting choice (if you can suck up its colours).  Its 4K video, 60 FHD fps, are all interesting and certainly useful when needed.   

Also why did Canon not solve with the 7D the aliasing/moire crap?  Canon really does not get it, they aught to be releasing 4K raw video shooters in aps-c with the 70D AF touch screen (JM2C) perhaps this will be the 80D, a dream for indie film.

Hello everyone i'm new so sorry for the stupid questioning :)

i just bought a 70d hoping I could install ML. as read on this site the stable version is still in developing (did I understood good?).

So what i was thinking is to install the nightly builds, that are released for the 70d too.

what i do not understand is:

Some feature does not work (ok this is a beta, this means that if i get some error i can damage my camera? or just that feature does not work and i cannot use it?)

The firmware ML load every time from the sd card: this means that the original software will never be affected in changes? so if something wrong succed, i just remove the sd card and boot the original firmware?

and last, did someone tried on the 70d?

thank you.

You should ENJOY your 70D for 3 to 6 months or so, learn it...love it--AS IS.  Then and ONLY then consider Magic Lantern.

When THAT day arrives, read and read and read and read and read the forums.  For every question you write, you should read at LEAST 50 posts--all the answers are in here, REALLY.  Use the search feature, too.

Post by: ShootMeAlready on September 25, 2014, 06:23:12 PM
For those who want to enjoy the 70D as is for now.  My suggestion is play with picture styles.  Read up on flat picture styles, because that's the best way to max your EV in H264 (without ML).
Three I have rather liked include the two from Marvel for free 3.3 (slight orange skin hue - good for southern sun) and 3.4 (slight green skin hue - good for northern sun), and look-up Simlaar's flaat_11, (slight yellow skin tone hue - good for indoor lighting).  The flaat_11 really max out the EV (11 EV).  There is a flaat_12 (which is more of a 11EV+) but its very noisey in heavy shadow, so I am not able to use it to get 11+EV. 
Load the picture styles and remote shoot using the canon lap-top usb utility, you will see a curve which shows you just how effective a flat/flaat picture style is on the curve.
Also white balance is so important, as with H264 its baked in, and canon's auto WB is crap.  So until ML raw is here, I humbly suggest play with pic styles & WB (oh yes turn the contrast & sharpness all the way down, deSat = -2, for flat shooting).

There is a whack of picture styles for canon out there for free, that are like special effects (sin city: only red, only blue, only red-yellow, etc.). 

Correction: Skip the Simlaar flaat_10, _11, _12 for high contrast shots.  They fall apart in shadows.

Hi,
I have been interested in picture styles and am spending more time trying new things as I wait for ML to arrive.

I have seen that there are many picture styles available, from many users and as a newbie to the party, it's been a painful task trying to find one that is either good, or does what I need (as there are so many)

I have read that their are some picture styles that allow users to shoot (in camera) a style that is much like a Hollywood action trailer, Inception, dark night, terminator etc?

As I won't be grading, port processing these particluar clips, I'm looking for a picture style that would let me shoot a short video clip that straight out of camera, would have that cinematic look and feel to it? Like a Hollywood action movie, very dramatic looking.

Is this possible with picture style or are most of them designed for flat look which requires the users to grade it later in lost?

I just want to create a little trailer that requires no post, no grading, no after effects and will look like a dramatic Hollywood action trailer sooc?

There is a website with 123 picture styles, but I try them, and to be fair, most of them are not that great and look bad? Do you know of a resource that has curated, the best, high quality, tested picture styles that are the cream of the crop? As I'd love to have a "dream" picture style for making short clips of the kids and/or wedding snippets, action or dramatic movie for when my friends are bmxing or Doing stunts etc, but there are just to must floating around that are supposed to be able to do this, but after going through the painful process of testing about 70 of them, I feel like giving up :D

Is there a good resource, comparison or example location for picture styles or do you happen to know of any amazing picture styles that can do the above?

Cheers

You want dramatic but dont want high EV.  Hmmm.  Your best bet is monochromatic.  The film noir look is the best in camera dramatic look.  The reason most folks post process is things like skin colour, sky colour, and to get a high EV contrast with detail not just blotchyness (as well as a host of presets which make life easier to get the cinematic look one wants).  For accent I would suggest try the sin city looks (only red, red-yellow) combined with your monochromatic that's about as dramatic in camera s it gets.
Here is a thread on the sin city look: http://www.magiclantern.fm/forum/index.php?topic=1398.0 
Look around you will find only red, only blue etc.

However if you really must shoot in camera with skin tones the 3 I recommended can be used, just set contrast & sharpness and saturation to values achieve your final look (test it on some short clips).
Film grading for digital video, however is very important, in the very least you should quick colour correct every clip.  White balance is crucial with H264.  Have fun, learn something and see if you like the results (better to be shooting
than not!).

Thanks for that :) I'm going to check that link out now as that sounds very interesting indeed.

Yea I know it sounds weird to not want full range and quality. But I'm not a film maker, just a hobbyist looking to create fun movie style videos of my family friends etc in specific scenarios for my own entertainment and not for paid work or commercial etc.

Quick question, I've just bought the cinebooster picture style for £5 and it comes with a pf2 and a pf3 which one should I use on a 70D? No reply from their sipport site as of yet?

Pf2 is 9kb and pf3 is 400 and something kb... All my others are pf2 and this is the first time I have seen a pf3? Should I stick with the pf2 or use a pf3 if it's abailable? What's the difference? If they are the same why have 2 at all?

Cheers :)
Title: Re: Canon 70D
Post by: ShootMeAlready on October 01, 2014, 06:31:51 PM
 cinebooster picture style  pf2 or pf3

Well I tested both in TV mode, shutter=1/50, EV=0.  I tried then in low light and bright light.  I adjust Sharp&Contrast all way down, and sat -2 (this is the video flat settings).  I leave hue to whatever the preset is.
What I found was that when the AF subject was in bright light, the background shadow area falls apart (noise and banding).
I also noticed that Simlaar's flaat_11 and flaat_10, which retains higher DR, seems also to have banding in shadow with such high contrast shots.

The Marvels 3.3 and 3.4 worked beautifully.  They did not have the highest EV/peak retention, what they tended to due with shadow was underexpose, which was more cinematic than banding/noise.

When the AF subject was in low light, the fore/backround in bright light, I observed for the flaat_11/10 in its attempt to remove shadow it brought in detail with noise/banding, but the Marvels held their own
AF subject had negligible noise. 

Annother one I liked, from Cineplus was CINEMA.pf2. When adjusted to video flat settings, I was amazed that at sat=-2 the colour was too strong! Its preset was sat=0 which looks best.
Now it is generally darker then either of the Marvels, but where it shined was when your AF subject is in low light, and there is bright light in the fore/background.  Its general darker
picture clamps down on the highlights adding detail (acting like an ND filter).  In high contrast settings you have to choose between overexposure and under exposure, your camera cant handle both,
and so generally you expose based your AF subject light, so that means with fore/background you get one or the other?  Overexposure is worse because a subject framed by white without detail looks very cheap, underexposure
looks more cinematic because it frames your lit subject in blackness.  When you use the CINEMA profile it rescues the overexposure detail as much as possible, so its a special purpose picture style.  You could use
it to shoot very bright AF subjects as well since it lets you open the aperture more for blurs backgrounds acting like an ND filter.  The colours for all three of these pic styles were very nice on skin tones,
as they all have been crafted and tested for this (assuming your white balance and exposure are good).

I did this all on the 70D but its only slightly better than the 600D/T3i, and I think the same will be true for canon aps-c.

I shoot flat, but even if you shoot with the default preset settings of each pic style, the above is still true for HDR settings in terms of banding and noise.
For general shooting, its safer to go with picture styles that handle challenging HDR environments as they are the most versatile.

From what I know from 100D, Canon's task structures changed, so QEMU will definitely help with this step (this will also be useful for 6D). But we are pretty far from emulating most Canon code in QEMU, so it has to be done by somebody with a camera.

But running ML in QEMU is a good exercise to get started. Here's the dumper, confirmed working by k1w1 and hpfrnsk:

dumper-70D-qemu.fir (http://a1ex.magiclantern.fm/bleeding-edge/blind-dumper/dumper-70D-qemu.fir)

It dumps 32 MB from 0xF7000000, which covers both ROM0 and ROM1 - that's what you need to run ML in QEMU. For analyzing the code, you can load ROM1 (the second half of that file) at 0xFF000000.

Usage: run firmware update, then go to play mode (make sure you have an image there), then look on your card. Keep the dump for yourself, do not publish it online.

Ok this is where I got today with QEMU:

Code: [Select]
[DebugMsg] (129,3) @@@ dwHdmiPhysicalConnect = 0(964)
[DebugMsg] (138,3) Variangle State 1
[DebugMsg] (138,3) HotPlug WifiSetting = 0
[DebugMsg] (138,3) CreateTask Master End
[DebugMsg] (141,3) emSlaveChangeCBR : AUTO_POWEROFF (1)
[DebugMsg] (141,3) emSlaveChangeCBR : UILOCK (0x0)



 8) 8)


So does this mean that ML is actively being worked on, if so that's fantastic! I'd love to get even a few of the ML features on my 70D it would release me from the awful constraints of the standard FW! This is fantastic news if you are working on it! Fingers crossed and thank you :)

re: 70D
Hi.  I'm the emmy award-wining DP "justshootme" referred to.  We're finishing a documentary of cranberry harvest in Oregon and the 70D proves itself to be light years ahead of other cameras in the doc style shooting.  Instant focus both through the touch screen and AF button enables a doc cameraperson to keep up with the action and be in focus.  Only downside for me is the noise that begins to appears at ISO 800-1000.  So if and when ML takes off the shackles of the 70D it will be without a doubt the best for the street (outside-the-studio, no focus puller) filmmaker. 

Does anyone know what bit rate the 70D's capable of processing and what bit rate would be required to output ML raw video off the sensor to the card?  I read sometime back on the ML website that the 70D never would be capable of ML because it's processor couldn't handle the bit rate.

(And just to finish my findings on focus - The GH4 takes 3.5 seconds to find focus. The Sony a7s takes longer and does that disgusting creeping in on the final mark which by that time is now out of focus.  Focus first.   That's the priority of the cameraperson. The 70D's a dream to use in a fast0-unfolding scene.  I'm going on about this because so many "experts" jump over the primary responsibility of the cinematographer so they can talk about how new cameras can shoot 4K or at insanely high ISOs.  What does it matter if the shot's out of focus.  The 70D is the quiet king of the hill.  The only flaw is the sensor.  For fast focus, the 70 D is king. Please see this video to see how it performs:

1. Sony shooters only care about shadow detail and dynamic range.  Focus--so passé!

2. The sensor/processor of the camera isn't the issue but the write speed of the SD card.  I believe the ONLY body capable of FULL HD RAW is the 5dM3 (CF).  The 70D shares the same SD capabilities of the 6D (among others) of 40 MB/s (unless I'm mistaken), so you might go there

Thanks Fletch for the video.

The 70D RAW video expect in 16:9 aspect 1280x720 @ 24fps continuous.  If one changes the aspect to 2.35, then one can shoot 1280x544 @ 30fps continuous.  If you use 2.35 aspect then you can shoot 1152x350 (1.4X post stretch to 1152x490) @ 60fps continuous.  It will also do 1920x1080 @ 11fps (crop mode) and 1920 at 2.35 aspect 15fps, and at 2.67 aspect 17fps .... all of which is good for establishing shots with minimal motion.   If we look at the 6D (which is closest in memory and controller speed) 1792x1008 (no crop) for 120 frames (5s) @ 24 fps with motion (I expect at 1920x1080 with crop it would be close to 5s).   This is based on a 40 MB/s controller, so memory card write speed (which is unreliable as it says "up to") should be 50 MB/s+ to realize this.

FF have bitch of time to nail focus on moving subjects (all the Shallow DOF is too much), the 70D is the B camera for Rack focus shots and well lit action shots.  The 5D mark iv rumoured for Q1 2015 release may do it all, have the FF & 70D focus system (or enhanced version), the tea leaves need consultation on that but some are suggesting it will.  Even when it comes out, there will be some time before its shooting raw (1 year lets guess), as it will likely be a new code base for the ML team to ferret their way through - so the long and the short of it is the 70D will be the best HDSLR AF in town for a while.

I am planning to work on this in my spare time. This was a nice adventurous journey for me in regards of learning QEMU and learning how ML code parts are related to each other.

Post by: fletch_cinebootcamps on October 14, 2014, 06:31:12 PM
This is a deep question for someone whose been "under the hood" of these Canon DSLRs.  Is the 70D's sensor noise (visible dancing in the gray tones when you get above ISO 800/1000 filming video) 1) just a function of the sensor itself and the 70D's ML RAW video will never look as good as the 5D M3's ML RAW video, or 2) a product of the cheaper components used for compression in the 70D (so if Canon put better components in, the "noise" would not be apparent until you reached ISO 1250 or even 2500), or 3) the processing path in the 70D is the same as the 7D's but Canon has turned off a few noise filters to degrade the image to align with the 70D's price point (and make the 7D seem like a "step up" in quality)? 

I heard that often it costs so much to make a variety of chips that Japanese manufacturers had the same chips in their gear, and they would deactivate and activate features to make the higher priced gear appear better, but the innards are all the same.

With that said, here is my final question: So, has the ML update that's working in other Canon DSLRs helped other Canon DSLR sensors become more noise free? Or is the sensor/processing flow just "noisier" and the ML workaround won't bypass the "don't fix the noise" switches I'm guessing exist?

Thanks, dmilligan.

I emailed Roger regarding this issue to get his response.

As you may know the Canon 70D has an incredible breakthrough in focusing which is excellent for motion picture people.  See my tests of the rapid response of the 70D with a 70-200mm Canon lens.

http://vimeo.com/102350772

And more appropriately this test of noise between the 70D and 5D M3.

http://vimeo.com/101311268

So, I look forward to Magic Lantern unleashing the power of the 70D's sensor but I'm wondering if ML can do the whole job of removing noise or is the noise from the sensor itself (and not from compression and processing Canon does to the image) and ML will have little effect on it.

BTW, while I enjoy reading, I'd like your opinion.

I find myself in the position I was in when I asked an Alpine Electronics rep to tell me the things Alpine does behind the curtain to make their car stereos so much better than the competition.  He just smiled and shook his head, "Let's just say that it sounds better."  Later I found out the whole story (Alpine's the only car stereo manufacturer that doesn't make living room stereos. Hence Alpine uses only components designed to be in sub-zero and death valley temperature ranges, plus endure vibration tests, ambient noise in the car environment and on and on.  Everything they put in the stereo was designed to be in a car.)

I'm wondering if ML can do the whole job of removing noise or is the noise from the sensor itself
The first link I posted details all the various sources of noise.

At high ISOs the largest noise component is usually not the electronics or even the sensor, but the light itself. This is known as "photon shot noise" and it's due to the discrete, quantized, particle nature of light. At high ISOs we say that the image is "photon noise limited". This type of noise is very difficult to remove, and removal is best done in post with a high powered computer (not a dinky ARM processor in the camera).

At lower ISOs, the largest noise component is typically FPN "fixed pattern noise". FPN is due to slight manufacturing imperfections (when CMOS chips are made, not every transistor is perfectly the same, so some sensels may end up having slightly more or less amplifier gain). This gain is "fixed" in that it doesn't fluctuate from frame to frame, so we see a fixed pattern of noise. This is the easiest type of noise to remove because it's not random, so we can simply take a dark frame (capture an image with the shutter closed, no light), which will show the FPN, and subtract it (http://en.wikipedia.org/wiki/Dark-frame_subtraction) from a light frame. This is what the "long exposure noise reduction" option in your camera does. It takes a regular frame, and then after that's done, it take another identical one with the shutter closed and then subtracts them. You can also do this for raw video using ML, though you have to do it manually in post. You can capture a short video with the lens cap on and then use that in post to subtract it from your actual footage. This only works for raw data though, once the image has been demosaiced and "non-linearized" (and compressed, as in H.264), the subtraction doesn't work any more.

Are you telling me NikFreak and got this working in Qemu in a matter of days! This is outstanding and I for one am incredibly grateful for this work. €1500 euro went to the dev, and from what I can tell no work completed or present to the backers, you have amazed me in what you have displayed for free in a matter of days? Truly fantastic!

If there is anything I can do to help (70D owner) I am here to assist in any way I can. I am desperate for some of the ML features on my 70D such as Dual ISO, intervalometer, more FPS options for video (like the easy MP4 time lapse effect) M mode + Auto ISO with EC etc as these features would really allow me to do the creative things I want to do with my camera.

It would stop me from being confined by the arbitrary restrictions of the poor/lazy default firmware, and would allow me to get creative with my camera by removing the restrictions that are imposed on the hardware for no apparent reason.

It's features like ML that truly allow users to use the tool in a creative way, not just in the way we were told to.

This allows our imaginations to be the limit, not the firmware!

I can not wait for this to be available. If there is any thing I can do to help, please let me know. If anyone else can help, test, code, bug test, troubleshoot add features etc let's all assist nikfreak and make this a reality for the 70D!
It really would completely change the way I use this hardware. We could all probably benefit in some way from it :)

Which camera will be better for video shooting? Im not good at manual focusing (im wearing glasses etc), but im a good at raw postprodction and color grading.

70D or 7d mk1? Is there any possibility, that in future 70d will be as good as in raw shooting (or not so far) as canon 7d?
I know- 7d has CF cards, dual processor, but 70d has new digit 5+, and MAYBE faster SD writer/reader than 6D or 60D?
I am doing a lot of documentaries, sport, traveling, but also music videos, very short movies or simply ads.  Objects in focus are same important as colors, levels, blacks, wb, shadows and highlights....

Which one will be better?

Read the last 6 pages or so, Ive made a number of posts on what the 70D can do, and should do when ML with RAW is available. 
Basically focus is your most important concern before RAW with video.  The 70D is hands down best.  Check over last 6 pages my posts you'll find links to videos that show the 70D AF test vs 7D (Northrop video).  The 7D is not that great as a primary video camera.   I would suggest look at the 50D over the 7D for cheap RAW, of comparable quality.   You might be able to afford both the 70D($900 new) & 50D ($400 used), which can share lenses.   

Correction: Did not see the Northrup AF test links, I put them on another site.  So here are the AF test links.

70D AF test, low-light test and comparison which puts the 7D to shame and shows that the 70D in low light is good to ISO 3200.

The 7D MII has the clean HDMI output 4:2:2 8 bit.  It has the 70D AF system as far as locking.  You could on a monopod track movement as long as the subject stays in frame.  However its focus is obtained by dialling up the focus point using buttons.  What it does not do is pull focus by touch screen (if your very good with buttons or MF you can pull focus during video).  I dont think the 70D will ever get clean HDMI outs.  It will get RAW video, at 720p for the most part (see back posts last couple of pages for details) you may want to look at the 7DMII for steadicam work.

With regards to the discussion earlier about the 7DII versus the 70D, the main consideration is price point (at least, for me).  As I posted last night, I picked up my 70D for about $850, after shipping.  The 7DII will clock in around $1800 until prices start to drop a bit.  That leaves me with almost $1000 in my pocket to pick up accessories, such as the shoulder rig, battery grip, spare batteries, and memory cars I also ordered.  It also leaves me with enough cash to get another STM lens to take advantage of the 70D's smooth tracking focus.  If you are looking to pull focus manually, a follow focus rig is the best way to go, regardless of what camera you are using.  I'm holding off on a follow focus system addition to my rig until I see just what the 70D can do on its own.  As a beginning filmmaker, the 70D is speaking all the right language to me!

The 70D doesn't "require" a filter of any sort, let alone something like a VAF filter.  Why would I use something which both reduces my resolution and hinders the autofocus?  If noise or moire is an issue for someone, the options are better planning for the shot or using software tools in post production to reduce the noise or moire.  Neat Video and NoiseProof Pro do a fine job of this and without costing resolution.

If someone has the money and desire for a 7D, more power to them.  I would prefer to work within my budget to keep funds free for more or better lenses and other accessories.  The 70D will work nicely for me.

VAF Filter is an absolut need for the 70D, I use The VAF with the 700D, 650D, SL1, No autofocus problems at all.
70D Moire is Huuuuge. What you have to do is buy the VAF, and sharp in post, Noise on Iso over 1600, is considerable, but controllable

Ok up till now I was excited about the fast video AF tracking of the 70D. 
So take a gander at these still photo racing shots made on the 70D.  All of the left turns made on a 70D, and some of the right turn as well.  Simply awesome.

https://flic.kr/p/pSixoL

As for the curious like me here's what the shooter told me:
"I used the 400mm f5.6L for that shot. Another lens I like and used for many shots is the 70-300mm L. "
"Shutter speeds were 400-1250 in shutter-priority mode – often with exposure compensation, ISO 160-640, F5.6-F9, AI Servo focus set for fast change. Many reasons for all changes of settings depending on whether panning or not etc.
All the shots from that left hand corner were with the 70D. Some of the others too but right-hand corners were about 70% with the 5DMKIII as I could get closer."
He also stated he was very happy with the 70D, and found some features lacking on the 7DMII, and since he told me he's bought every version of the 5D, I don't think cash was holding back.

You really think the 7D2 wont need a VAF filter if a 70D does?  The cameras are really not that far apart... from what I've read, the Moire problem is still there with the 7D2.  Either way, if the 70D "requires" a VAF filter, I'm assuming the 7D2 will also "require" one.

Anyway, I'm a proud new owner of a 70D, and I absolutely love it so far.  I ended up discovering Magic Lantern after ordering the camera, but at least I also have a 700D to use it on.  Very excited to see a 70D port is being worked on!  Bummer that the dev's work will be shelved until December, but at least it's in progress, and I can't wait to start using it on this 70D, especially if it enables clean HDMI 422 out.  :D

So its kind of occurred to me, that when I shoot video with Tv priority (i.e. 24 fps, Shutter=1/50s, EV=0), on any of my zooms, that not only can I pull focus with touch screen,
but with AF facial recog. set it locks focus as I zoom.  And the interesting part is its not screwing around with aperture/shutter settings as I zoom, so the 70D is making my sigma 18-35mm parfocal!!!

It does the same for my sigma 50-150mm II f2.8.   It can behave the same with manual. 
Its just the Tv mode helps you get a fast consistent exposure when you dont need shallow DOF or if the lighting does not change.

If the light is changing as you pan/follow the subject or need shallow DOF then by all means use manual and you can still achieve a parfocal zoom.

So let's see the 70D not only pulls focus it can make a lens behave parfocal.  Rather awesome.
Not every camera has a decent AF live focus lock, so this is not common.

Is there any hope for clean HDMI 4:2:2 output on the 70D?  If Canon can enable it for the 5DIII in an official FW update, I get the feeling they could also do that or the 70D if they wanted to, but they most likely wont if only to help justify the 5DIII's price tag.  Just reviewing some footage I shot this morning and holy shit, the compression makes my eyes bleed.  Crazy how my 700D can shoot better looking video than my 70D because of ML, when I paid $550 for the 700D and $1K for the 70D.  Anyway, if ML can enable clean HDMI out, I will totally be getting an Atomos Ninja to pair it up with.

Nevermind, just saw this in the "don't request" section...  whomp.

No 1080p RAW for 70D.  A camera with so many awesome features, but doomed to yucky compression for eternity.

If your need for video is 50% or more of the time, you should purchase a GH4 or other TRUE video cameras. In my opinion, the GH4 is more like an 75-80% awesome video camera that takes decent stills but cannot match the 70d in photo sharpness & overall quality.

If you occasionally shoot video, but mostly photo, the 70d is perfect because even a novice can get decent results & the correct focus without too much effort. ML will improve the 70d but I doubt if 1080 will be achieved. Read the ML 60d thread. Expect similar but better results than what ML obtained with the 60d.

Just thinking... the 7D2's LCD screen wont be a touchscreen right?  That kind of gimps the whole video autofocus thing.  The camera can't read your mind, and often times, if there's not a face to focus on, the focus will go somewhere other than where you want it to go.  Half of the reason the 70D's autofocus is such a joy to use is the ability to simply touch where you want the focus to go.  It's so easy to rack focus between 2 or more subjects in a shot.  I'm sure there will be a way to select focus points that aren't faces with the 7D2, but I doubt it could be anywhere near as just tapping.  The 7D2 should really have touchscreen to make best use of the dual pixel AF.

Here I was thinking that eventually, down the road, I'd upgrade from a 70D to a 7D2 and finally have all the features I need in an APS-C dslr (dual pixel AF, 1080p60, most likely 1080p30 raw, and the ability to use my Canon STM glass) but I really don't think I can give up touch-to-focus.

I wonder if Canon will ever make a prosumer-level DSLR with both touch-focus and a CF slot...

I do ~75% video and ~25% stills.  You're probably right about the GH4.  I don't know why I'm so loyal to Canon, they don't do much to deserve my loyalty.  I guess it's partly because of the money I have invested in Canon glass and my familiarity with Canon equipment.  When studying video production in college, we had mostly Canon and Sony gear.  I always went with the Canon video cameras and DSLRs, so now that's just what I'm comfortable working with.

IMO the 70D's AF still bests any mirrorless DSLR's AF system right now.  For shots where my focus distance is mostly static, I'll still manually focus, but for rack focuses and tracking while both the camera and subject are moving around, dual pixel AF and touchscreen is just unbeatable.

DigitalVeil - In the early 2000's I did a lot of video work; weddings, etc. so, in my mind I want to cover both worlds; great video & photos. I'd love to find one product that fills my needs without compromise. But, these companies don't work like that. If they load one camera with virtually every needed feature they'd loose money! There would be no need to upgrade. Companies fill consumer needs to what price point the targeted consumer can afford & that's it. Consumers would ask why buy a EOS Mk5 III when I can save $2500 & get a 70D. The 70D has a smaller sensor but big deal. $2500 buys lots of great lenses. Like all companies, they do a market study & aim their product to hit that market.

Like you, I'm vested with Canon lenses. The truth is, Canon has that familiar feel that I've grown to like. Reinvesting in a new brand would be expensive. The GH4 IS very tempting & the truth is if were marginally close to the 70D's photo quality, I'd make that investment. But, as the GH4 blitzes the 70D in video; the 70D blitzes the GH4 in photo. I take more photos & that ends the debate.

Hope this helps!  :)

For christ sake, if you're fortunate enough to own a pretty decent dslr like 70D make use of it rather than pleading devs and that lone person, who doesn't have camera but still does something. These things, they take time. Give them that time. In the meantime - use your gear to the fullest, study it, use it. There are bottlenecks, yes, but can get around a lot of things. It's far easier to have a more friendly software than it is canon's, but (except for the backers of 70D) we're getting this awesome stuff for free. Learn to use your equipment, rather than asking for someone to make it more usable.

Whoa there cowboy.  Chill out.  I think people are just excited at the prospect of what ML could do for their 70D, and they know it's close to being finished.  If Nomad is tied up, and nikfreak is capable of finishing it... well then I see no reason to have a problem with that?  Nobody is angrily demanding this port, we're just excited by the possibilities of a 70D+ML, which is now within arm's reach but on a snag.  And obviously we are using our cameras to the fullest extent - you don't need to tell us to do that.  Nobody is going to buy a $1K camera and let it sit there uselessly until the ML port is finished.  But let's be real here - no matter how much you work to maximize your footage quality within the limits of the default Canon FW, the h264 compression at the standard ~10-12Mbps bit rate still looks yucky.  My 70D has become my secondary camera for my video shoots now because my 700D is the one with ML at the moment.  So obviously we're anxious to see ML on these devices.
Title: Re: Canon 70D
Post by: ShootMeAlready on November 06, 2014, 06:21:35 AM
I am probably getting ahead here, but I think the 70D will face a rather unique challenge compared to the standard ML build.
The touchscreen focus, is an integral feature for the 70D, and yet its not clear if that can be handled with ML.

My observation is that DSLR controller app (Android), basically does not work with MLV raw.  Why? because it hooks into the Canon firmware.
Canon's EOS utility does not work with MLV raw, probably because of the same reason.
So the 64$ question is will MLV raw support touchscreen AF??? And if so, are we doomed to a 3" touchscreen.  Its just that putting a 3X LCD hood + diopter will not work because you need to touch it! (foldable's are not practical for touch either).
If you use the HDMI port then you only have a monitor, but where's the touchscreen???

To really unleash the 70D AF, it seems we need MLV raw working on either a EOS utility (like) on a 15" laptop via usb or DSLR Controller app (like) on 7" tablet via usb.  ~ JM2C. 
Since the issue with the EOS utility is that its framerate is too slow, its unlikely that it will be improved unless Canon does an update of the software (meaning its not an interface issue).
However the DSLR controller, seems to be a better choice, perhaps a ML interface emulator can be run on the android, so that DSLR controller thinks its talking with canon firmware ???


The hybrid approach would be to use the 3" LCD for touch, and port the screen through HDMI to a monitor.  But this only works if the 3" LCD is not blanked while it outputs the HDMI.

There is always the clean HDMI out "ML solution" but that seems to be a rats nest, which we are encouraged to be discouraged about, which basically means not raw even if it happened.

CORRECTION:  It appears HDMI outputs, will never work, as the LCD will always be blank ...  It appears the clean HDMI outs is something ML cant make happen ...
So another approach that will work (somewhat) is to hack the LCD loupe, basically cut out the bottom bellow the 3X magnfier, so you can fit your finger in.  Then you will have 3X magnified screen, and be able to poke around.
This is a hack of a different kind.
 
Another approach, which may prove simpler (dont know if folks have hacked wifi controls ???) is hack the RC-6 wireless controller or the DLR remote (i.e. interface wrapper), so that when it triggers a still shot, in MLV RAW the video record turns on/off.  Either one if used with DLR Remote program means a 7" Android tablet can be used with touchscreen AF.  However since we have not seen MLV raw video stream over wifi, the question of data stream throughput / overload has to be looked at.

Vagabond

Ive looked into this quite a bit previous on this thread.  What folks and I observed was that in crop mode on a 70D, when there is no line skipping, there is more noise.
The increased noise provides for a softer picture.  So although the video you linked, recommends sharpening in post (which is good), its still a softer image which is less to work with.
With full frames, crop is better because they have less noise to start with because of the sensor design.   If they end up with aps-c quality noise, its still good !!! Also FF benefit in a wider FOV when cropped as they don't have the 1.6X.
I bought a 70D VAF, because I like to shoot video that includes streets, hydro wires, street car tracks, bricks, blinds, wooden fences, etc. that cause moire/aliasing.  I do think 3X on aps-c is good for moon shots or other high contrast/vivid colour shots with softer edges (sunsets/rise good).  However 3X on street/car lights or any sharp high contrast/vivid colour edges create CA (the dreaded purple fringe, fixable in post but a pain). 
I think its kind of the same issue with MFT as with aps-c crop, harsh/softer colour tone (hard to get great skin tones), low light poor, and weaker shallow DOF.

I made my 70D repository available for public on bitbucket.
Remember: This is for QEMU and boots up in QEMU but the device tree (70D) should be fine to be used (copy & paste) with unified when you adjust the makefile. Sent a request for an installer fir weeks ago to a1ex but didn't get one.

I won't be held responsible for what you guys do with this. I doubt that some of you writing me PMs know what they do cause I got some strange questions but anyways I am just sharing what I did upon requests. I still recommend y'all to wait for nanomad but wish you luck with this if you still try it out. I cannot blindly do it.

Many of us here, who've owned the 70D since its debut and have run ML on previous bodies find ourselves being pretty damn virtuous and in your same position.

My advice would be for people NOT to buy the 70D in hopes of using ML on it. Will be obsoleted by the next thing out before ML is working. Just not enough dev's and too many FW's out there, so ML dev's have to pick a battle and go with what's chosen. Sadly, it's not the 70D.

Title: Re: Canon 70D
Post by: ShootMeAlready on November 25, 2014, 03:59:41 PM
A main advantage of the 70D is the touchscreen AF, with smooth continuous focus.  Yet for ML RAW shooting that's a problem, how do you set/check focus?
Using a HDMI out screen, means blanked LCD, and loss of touchscreen.
Using USB apps (laptop or Tablet/android), yes touchscreen AF is kept but the problem presently is no software supports MLV RAW.
You are left with shooting MLV raw off a 3" LCD, which means ML 5X-10X zoom is all you have.
The only solution I come back to get a bigger than 3" screen for focus set/check, is a hacked loupe, 3X magnification with cut out bottom so you can poke around with your finger.
The other MLV RAW limit on a 70D is the 720P res imposed by the SD controller speed.  For those who crave higher res RAW with great IQ, look to a camera with a fast CF controller (5D2 or 5D3 cinematic giants).

70D has great IQ, excellent quality for say indie film. I never bought this camera thinking ML support as the make or brake for it. 
Using EOS remote or DSLR controller app on a 7"+ touchscreen, Marvel pic styles, and decent grading it can produce great  footage right now, that's why to buy this camera. 
The 70D could be a RAW fast smooth continuous AF champ, that's were this tool wins big over the rest.

Tom, you could say that about ANY camera.  Not many people upgrade their camera every single time the next iteration comes out.  It's not like ML will be immediately available for the 80D or 800D either, and just because those cameras might not get a ML port until the next generation is around the corner doesn't mean they'll suddenly be obsolete when they get ML.  Most of us 70D owners probably bought one intending to keep it for a good long while, and since we do have a 70D ML port working in QEMU already, I think there's a good chance we will see it in practice while the 70D is still relevant.

I'm not following what you are saying here.  Yeah you're stuck with the 3" LCD if you wanna keep touchscreen AF while shooting RAW, but besides a larger view, what else do you gain using an HDMI output screen?

DigitalVeil

A larger touchscreen just means more fidelity in AF set and checking.  Do want to keep plugging in a monitor just to focus check your last shot? Plug-in then take it out to shoot your next raw clip.   A 3" LCD is fine for run & gun, but even then Ive seen some 7" tablets in the hotshoe which are even better for run & gun.

Congrats nikfreak  8)

Wish you all the best with your new Friend.
 

I am a newbee on this so my question maybe is trivial.
Is it possible to have the 70D shot only with electronic shutter like the 40D , 50D or 5D2 does and now many Olympus or Sony Cameras?
Timelapse use a lot of shutter actuation so it would be great not having mechanical movment for shotting: it would save a lot of the 70D's lifetime.

Cheers,

Longtime lurker.  Had ML installed on my T1i which I have since gifted to my sister.  I upgraded to a 70D for a relatively cheap and versatile DLSR for cinematic shorts.

Can't tell ya how excited I am to see a ML version in the works for the 70D!

Tom, you could say that about ANY camera.  Not many people upgrade their camera every single time the next iteration comes out.

They do when it's their livelihood and the camera is "upgraded" enough to warrant the features. And the 70D is right in that place where it provides professional results but at a cost that only produces a terse session of expletives when it dives overboard, a housing leaks, or it takes a hit from a rapidly moving projectile (around 2,400fps to be somewhat accurate)

Just got a great deal from Canon on 70D refurb, like new, only 250 clicks. It would be great if ML is ported to 70D, loved it on 60D. Keeping fingers crossed...

Hi, any news about .fir from A1ex?

I'm waiting to test it compiling the source by myself.

I'm keeping italian ML users updated here: https://www.facebook.com/groups/magiclanternitalia/

nikfreak let me know.

Is Alex the only person here capable of making a .fir?  I mean, it's almost seemed like he's been oddly against even the idea of a 70D port from the beginning for some strange reason. Doesn't make sense, but his early comments seemed to give off that vibe.  I think he's also kind of drifted away from working on ML as a whole lately, like he was fed up with it or something.
Title: Re: Canon 70D
Post by: nikfreak on December 04, 2014, 10:49:04 PM
The 70D port won't arrive earlier by claiming such things. It's the total opposite of what you wrote. I know this for sure  8)  8)! Again, just a little bit more patience.

You might also have missed this:

...
My spare time has dropped to almost zero (usually I can barely find time to read the forum), so please don't expect major progress from me in the near future. I expect things to clear up around January or February; until then I'm stuck with personal stuff unrelated to ML (and unrelated to Apertus).

He's not the only one, but not everyone can. .fir files are AES-encrypted (and signed somehow IIRC?) and although the keys for some older models are available online, as far as I know those for the more recent cameras are not. But the .fir format is documented, you just need to find the AES key somehow, if you want to create a .fir.

I'm sure he will create an installer .fir once ML becomes usable on 70D. The code for that already exists.

It feels like Stripes, where we have to complete basic training ourselves.  That's a joke.
So without any offense to A1EX or G, who have done great work and spent long hours on the common code base which we presently enjoy,
lets enlist a guide on the .fir build process.   I think most want a ML drop under the xmas tree to play with over the holidays ... and things only get busier as the fat man's date night approaches, so lets organize the troups.

Inspiration here's two 700D raw videos, which if shot on the 70D, we hope could have been even better (not that he didn't do a great job).

The hard part isn't figuring out the .fir structure, really. In fact it's already documented on the ML wiki. The thing is finding the encryption keys. Those will likely never be published publically.

I've felt that from the start with the 70D. The T4i came out like butter, 70D seems abandoned and we're already over a year on..., so..., prob up to us. More on this later, but yes, I'm willing to dive in myself on it..

Cut some slack for @a1ex -- obviously he has already done a whole lot for all of us (along with the help of others DEV's such as g3gg0 & everyone else on board) & please let him enjoy as life as much as we all do, respectfully so.

Time we only tell if the ML crew feels the need of a ML for 70D and I know it'll come sooner rather than later.

You have read the former discussions about this topic?
Have you any new arguments to offer? The "we are more than before" doesn't count that much because it should be pretty obvious that this argument was valid then, too.

And one thing I really like to have covered is "Why may a profit oriented company as Canon (Nikon/Samsung/namethemall) be interested to add functions in cameras already been sold? Thus preventing the customers to have to buy new equipment and therefore diminishing the company's and shareholders profits?"
Title: Re: Canon 70D
Post by: ShootMeAlready on December 11, 2014, 04:14:19 PM
I heard a recent interview from one of the Panasonic top Dogs, and he expressed that he thought folk DIY developing firmware was interesting and exciting and viewed it positively, however they could never warranty issues arising from it.
So I suspect Canon feels much the same way, without ever officially admitting, they value the ML effort, but cant be seen to warranty one iota of it. Let's put it this way, canon loves to brag about how many motion pictures
a canon DSLR has been used.  And when you read the interviews you start to realize that ML is one of the key reasons.  So ML is actually adding prestige, respect, and notoriety to Canon DSLRs, which is way more than
their sensor development team has been earning.  So the extra publicity also adds loyalists who like FLYs on a flypaper, once they have sunk a few grand in glass become stuck.   JMHO.

I said it earlier maybe some donators missed it: I used nanomad's repository and continued his work. Without that it would have taken lots of time to get where we are now. So thanks to all donators and nanomad. We encountered some problems but finally discovered that there are different 1.1.1 factory fimware and that caused headaches. Anyways, I attached a screenshot of an early running minimal installation on my 70D. Made some good progress today  8)

Am happy that he set up the bases for you to continue and give to all of us ML for 70D.

one more:

(http://i60.tinypic.com/28nu6p.jpg)

some additional facts:
Title: Re: Canon 70D
Post by: DigitalVeil on December 31, 2014, 07:21:24 PM

  • Write speed for UHS-I sd card is max ~40MB/s (no difference to 6D / 700D)
  • Unfortunately we will encounter this same bug (https://bitbucket.org/hudson/magic-lantern/issue/1974/6d-in-live-view-mode-ml-menu-times-out) as on 6D (in fact actually it's a usable 8-10 seconds)

The 40MB/s is disappointing, but expected.  This is Canon after all, and they know good and well what they're doing.  They could have easily put a SDR104 (UHS-I 104MB/s) slot/bus in this camera for likely the same or minimally higher production cost, but they're aware of ML and they'll make sure it's literally impossible to shoot full 1080p raw on anything other than that $3.5K 5D3 (and maybe now the 7D2).  Even if there's some way to get clean 422 HDMI out of the 70D (highly unlikely), I dont think touch-focus will work with it, and it's still 8-bit.  Do you know yet if it's possible to go beyond 1728 width? Being able to shoot 1920 wide would be cool, even if that meant heavily cutting the video height.  I'm at least excited to shoot h264 All-I combined with 3x bit rate.  Should end up around 35MB/s and look a bit better than my 700D's IBP 3x compression.

All I want is a Canon camera that has both the dual-pixel CMOS touch-AF awesomeness of the 70D combined with the ability to shoot 1920x1080p24 raw.  I'm guessing the 7D Mark II will be able to shoot max res raw because of its CF slot, but the lack of a touchscreen really limits what the dual-pixel AF can do.  If there was a Canon camera like this in existence, I'd probably pay the huge price for it.  Guess I'll just keep waiting =P

Also, does the ML menu timeout occur every time the menu is accessed, or just sometimes? This same problem happens on my 700D, but only the first few times accessing the menu after boot.  After that, it stops timing out.

Oh, and great work again  :D

Title: Re: Canon 70D
Post by: ShootMeAlready on January 01, 2015, 06:44:53 PM
DV at 40 MB/s, expect for 1080p only in crop mode: @ 11fps continuous, and aspect 2.35 @17 fps continuous, and if memory buffer of 70D if its same as 6D, @ 24 fps for 5s.

Like the 700D/6D expect for 720p no crop: @ 24 fps continuous, and at aspect 2.35 @ 30fps continuous.

For 1152x350 no crop aspect 2.35 (stretch mode) @ 60fps continuous. Never tried crop with stretch mode, so perhaps with crop some higher res. @60fps is possible.  Probably avoid raw video @60fps for projects other than QHD.

And that's iff you have cards that actually write 40 MB/s.

Many thanks for your intellect and hard work.

You guys are overreacting.  40MB/s is good enough especially since the 6D is the same and i have gotten some great RAW video on the 6D.  If i remember correctly,  With a 64GB 95MB/s Sandisk card,  i was able to shoot over a minute at 1600x600 and roughly 45-55 seconds at 1792xXXX with 2:35:1 aspect ratio.  I went from a 45MB/s card and was told on this forum it would not be much of a difference but it was.  it doubled my recording time.  So the Card you put into the camera does matter.  Lets just hope the Dual AF works well with RAW video.

It's not "good enough" when UHS-1 slots can reach 104MB/s.  I'm not even talking about UHS-II, this is the UHS-I slot that is already in the 70D and other less expensive Canon DSLRs.  I think it's kinda bullcrap that the 7D Mark II has an SD card slot that reaches 75MB/s in addition to its CF card slot (redundant) while the 70D only has the 1 SD slot and it's limited to 40MB/s.

I almost wish these Canon DSLRs shot raw at 12-bit instead of 14-bit.  Obviously that makes them worse for still photography, which is their primary purpose, but when it comes to video the most noticeable improvement comes from 8-bit to 10-bit, above that it's hard to notice.  I know if these cameras shot raw video at 12-bit instead of 14-bit, we could definitely fit higher resolutions through that 40MB/s bus.  This is why I wish we could set higher than 3.0x bit rate for h264 shots.

Just wondering if anyone has tried ML with one the usb to CF or SDHC card writers.
It seems that if you avoid using the internal SD card writer and output to the usb, things might be faster ???

http://www.walmart.com/ip/All-in-1-USB-3.0-Compact-Flash-Multi-Memory-Card-Reader-CF-Adapter-MicroSD-MS-XD/40995370

Its a bit outside the box, not sure what the internal card writer does vs ML functionality in that department.
If we are lucky perhaps just a driver is needed???

but they're aware of ML and they'll make sure it's literally impossible to shoot full 1080p raw on anything other than that $3.5K 5D3 (and maybe now the 7D2). 


This is a little paranoid. Canon decisions are not about us, it is about their bottom line and ensuring all part specs are as minimal as possible so they can max their profit. I suspect ML has improved Canon sales to those who know, but has no impact to their other products. Anyone believe or know otherwise?

You could use an OTB (USB 3) cable to connect to the camera, and the writer.
The question becomes can ML use this device???  Perhaps a s/w driver is needed. I wonder if there is an Digic/ARM config. to use it.
I like the USB port connection because unlike the HDMI it doesn't blank the LCD screen, so if we can bypass the slow ass internal card writer ...

Does the 70D have a 3.0 or 2.0 USB port? I assumed 2.0 but I could be wrong.  The maximum theoretical throughput of 2.0 is 60MB/s but for reasons beyond me (overhead etc) you pretty much never see any USB 2.0 connection ever going above 35MB/s, so we wouldn't gain anything there.

Agree but it is what it is.  How do you know the 7D Mark II has 75mb/s?  Also I think Magic Lantern Chooses not to do 8, 10, 12 bit RAW and i think it should be an option.  It's silly and i do not believe their reasoning behind it.  I really think we can push these cameras to 1080p + if we had the ability to do 10 Bit RAW.

Unfortunately it doesn't really work like that.  The image sensor in these cameras natively uses 14 bits to determine what color a pixel will be. Recording images in 12-bit color instead of 14-bit color would actually require the camera to do extra work. In fact it probably takes the same amount of processing work as converting to 8-bit like it already does.  Raw essentially works by taking the full sensor readout, bypassing the h264.ini, and dumping that data directly onto the card without any modification.  Someone correct me if I'm wrong, but I don't think you can just "drop" the 2 or 4 least significant bits of a color value without completely ruining the whole picture.  You wouldn't just lose the range, you'd end up with an entirely different color for every pixel.  To convert from 14-bit to any other bit-depth, you'd have to run through an encoder again, and I'm 99% sure the h264.ini cannot be modified to do anything other than 8-bit.

You're wrong ;)

You can just drop the least significant bits without loosing much image quality, b/c these bits are mostly just noise anyway (if you lost anything, it would mostly be very dark, noisy shadow detail). The "correct" or "best" way to reduce bit depth would be to round with a little bit of random noise thrown in (for dither (http://en.wikipedia.org/wiki/Dither)), but there won't be a whole lot difference between that and just dropping the bits (it certainly wouldn't "ruin" the picture).

But even just doing something like dropping bits is too time consuming to be able to do it in real-time with the dinky little ARM CPU.

ML Raw recording doesn't even use the CPU to transfer the raw data from the raw buffer to the SD/CF card because the CPU is too slow for even that (just a direct copy). Instead we use some special hardware called the EDMAC. This special hardware device can move data around memory very quickly without incurring CPU overhead. Without the discovery of this hardware and figuring out how to use it, raw recording would not have been possible.

So, if we also want to do something like change the bit depth of raw data, we need to find some hardware that can do it for us fast enough, because while it would be very easy to write some code to do this, the code would never be able to run fast enough on the ARM CPU (b/c like I mentioned previously, even a simple direct copy isn't even fast enough). To date we haven't found such hardware or at least if it's there, we don't know how to use it. In the link I posted there is some indication it *might* be possible, should we ever figure out how to use the hardware mentioned in that thread to do this sort of thing.

While I have yet to read a Canon spec sheet that says its usb 2.0, the fact they have not noted it as usb 3.0, or provide clarification that such a compatible device is needed
it is probably usb 2.0.  More than a few folks have noted that actual usb 2.0 reader speeds max at 35 MB/s.

http://www.dslrfilmnoob.com/2014/02/01/usb-3-0-card-reader-speeds-matters/

So it looks like the next point of interest would be to connect to a SSD drive ???  That should maz. throttle the transfer rate.  Perhaps enough to get past 40 MB/s.
And if so that would work for even 550D and above cameras.

I do know that the 70D inherited the 90 MB/s All-I compression from the 5D MarkIII, so its got to have superior throughput processing somewhere? that can be tapped.

Thanks for explaining all that  :)  Good to know that about bit depth.

The specs say USB 3.0, which means much faster than 40 MB/s. 

http://www.cameraegg.org/canon-eos-70d-specs-new-sensor-digic-6-usb-3-0-gps/


Now the DLRfilmnoob found that usb 3.0, wrote twice as fast to fast cards as usb 2.0.  Since more than a few folks have noted that actual usb 2.0 reader speeds max at 35 MB/s
this at first estimate suggests a 70 MB/s card write speed.

http://www.dslrfilmnoob.com/2014/02/01/usb-3-0-card-reader-speeds-matters/

Which by the way, assumes your USB 3.0 connects to a card writer, how about instead a SSD drive ???  Now that would be fast!

But perhaps with ML on a 70D, the USB 3.0 maybe fast enough to refresh EOS utility (as it runs on 5D MkIII) which gets you into AF raw video on a 27" touchscreen. 


Interesting.  Maybe there is some potential there? Seems unlikely the camera would be able to drive the device, but I'm no expert on this stuff (yet :P)

Yeah with the 7D2 they specifically make a point to say it's 3.0.  If they didn't with the 70D, I'm sure it's 2.0.

I do know that the 70D inherited the 90 MB/s All-I compression from the 5D MarkIII, so its got to have superior throughput processing somewhere? that can be tapped.


All-I plus 3.0x CBR should be at least bit of a step up.  I wonder if the h264 encoder will actually be able to handle ~35MB/s without stopping.  Does anyone know if that works on the 5D3?

2 AF point is 19 .

I have a question the problem with the writing speed is for the camera or memory? if the answer is memory, we can get a memory with 95/MBs to 280/MBs and the problem gonna be solved...
Title: Re: Canon 70D
Post by: walter_schulz on January 03, 2015, 09:53:02 PM
280 MByte/s requires UHS-II and no camera supported by ML has this interface. When used in UHS-I mode Sandisk's UHS-II card will be good for about 45 MByte/s.
And Canon's SD-card interface is limited to about 41 MByte/s on 6D, 70D, 650D, 700D. On all other cams running SD (excluded 7DII) the interface is good for about half that rate.

Neither... it's the SD slot.  It's a gimped UHS-I bus with a max rate of 41MB/s.  You can use the fastest SD card on the planet and it will still be 41MB/s.

We talked earlier about attaching a USB card reader to the camera's USB port... if ML ever made that possible, I'd skip the card reader and just plug in a USB flash drive.  I've got a 64GB USB 3.0 stick that writes at 175MB/s, it would be amazing if I could just write date to that thing!  Only problem is there is currently no Canon DSLR that offers USB 3.0 that doesn't also offer a CF slot...

The pink/blue dots on the 650D and 700D are "focus pixels" which perform contrast-detection when autofocus is enabled in video mode, instead of recording color information.  Normally these are thrown away, but they are kept when recording raw.  The 70D has a totally different video AF system and shouldn't have that problem.

Post by: ShootMeAlready on January 05, 2015, 04:03:53 AM
Ok still thinking outside the box here:
It seems that 70D should have dual processor power, for its AF system.

If you put it in MF, then there is a lot less going on with the processors.
So it seems that if you load up one processor sends to the EDMAC to write to the card at 40 MB/s
Then with the other processor you write to the USB, now the only bottle neck is the bus. 

I did read in some article a 50MB/s bus limit, but you know I haven't seen any hard facts or measurements to know if that is credible.
The outcome is now raw video in two places, USB file, and card file. That's a crazy work flow, and likely best done by equal distribute between both.
But like I said its outside of the box, and perhaps an avenue for higher raw resolution investigation at appropriate time.

Another more generic thought, is that for all ML cameras,  in MF/Manual mode/Manual ISO  a lot less is going on with the processor.
So why not attempt the same, and see if writing to two places can max out the bus, and improve raw video capture!!!  Perhaps FHD on a 550D/600D (we can dream) !!!

Title: Re: Canon 70D
Post by: DigitalVeil on January 05, 2015, 06:16:01 AM
The 70D only has a single Digic 5+ processor, not two.  Even if it did have two, and disabling AF left one of them totally dedicated to copying bits from the sensor to storage, a dedicated Digic 5+ CPU still wouldn't be fast enough to do it at 24fps.  The 5D Mark III also has a single Digic 5+ processor and that camera must also use the EDMAC to copy data to storage in real-time.

I'm sure this is also just as unlikely, but I'm wondering if it would be even remotely possible to open up a 70D and swap the stock SD slot with a 104MB/s part.  If it were possible, I'd try it, working with hardware is something I like doing.

DV you may want to buy a spare SD card part first, and disect/ discover the components and PCB pin layout ... just a thought before you rip into your camera.
Here is a few for a 600D which I had been thinking to investigate.

Title: Re: Canon 70D
Post by: ShootMeAlready on January 05, 2015, 05:34:31 PM
AK you have raised a good point, one I have been wondering about.
Could one swap a 700D PCB for SD card into a 600D, and upgrade it to 40MB/s
But why stop there, why not try and swap a 50D or 7D PCB to get into a CF card? (assume one cuts into the body for the access?)

Then there is the 5DMarkII which in many physical size respects is similar to the 70D.
Could one swap its 80 MB/s PCB CF card ?
Even if the swapped in card in not fully maxed, would one get an improvement in raw video res., until max. limited by the bus or cpu?

I think if one were to buy a slew of these one could start determining do you need the whole card or can you just get a chip or just what?
We do know that Canon gimps models and reuses a lot architecture, so there is reason to expect some success in these swaps.

Maybe a few models share the same part, but the majority of them have different parts, which likely means each camera has a unique SD PCB custom-built specifically for that model.  The only Canon camera that possesses an SD slot spec'd above 40MB/s is the 7D Mark II which probably has the 104MB/s part.

In a perfect world, you could just open up a 70D and a 7D2, move the 7D2's PCB to the 70D, maybe do a small FW hack, and it would work.  The chances that would actually work, let alone the chance that the 7D2's PCB would actually fit into a 70D, are pretty damn small.

I'm not into unicorn chasing, but by buying and inspecting/measuring/dissecting/identifying component elements/chips for a few fast SD PCBs one might be able to make more informed conclusions.

Browsing around the forum a bit yesterday, I found another thread in which writing data to USB storage instead of CF/SD storage was discussed.  A1ex commented on it and surprisingly didn't say it was impossible.  Judging from his tone of words it almost seemed like it would be that far-fetched of an idea, basically saying you could theoretically write data to both the USB device and SD card at the same time and merge the frames in post, just like combining the 5D3's CF and SD slots for 100+20MB/s.

I'll try to look into it myself, although my programming knowledge is limited and I'm still very new to ML as a whole.  If this was possible we could unlock greater RAW recording capabilities for pretty much all ML cameras.

I do, but I'm not sure I'm in the financial position to risk breaking a $1K camera  :P and then I'd also need a $1.8K 7D2 to open up and tear down, unless someone can find the part sold by itself... And then what if the PCBs aren't the same physical form factor after all that?  What if the pins are different?  It's a looooong shot.

DV the journey of 1000miles, starts with the first step.  Here's an approach to consider.
1. What's the best upgrade chance?  Either 7DII, 50D, or 5DII. 
2. Get pics and measurements for all the three boards.  This is research by asking tech supports who sell the parts, for info. before you purchase.
3. Ask a tech support  for their opinion?  They probably have thought about this already, and may be able to point out any obvious pitfall.
4. Now if all is good, buy the one that fits into your 700D (for instance), the PCBs I found were not that expensive.  You may even want the tech support guy to do the install or write out the steps he would follow??? 
This is to minimize the risk, if you like H/w exploration you will eventually have to crack open a camera.
5. As for programming, that is probably not needed and if so that's what the ML team can handle.

Sorry Im too busy and have a shooting schedule for next few months. 
Besides I would want to upgrade a 600D, as that would be pure hacker glory to have it shoot FHD raw.  JM2C.

I think the time to explore the dual write s/w upgrade is after ML works reliably on the 70D.  Which I hope nightly drops soon occupy me.

Ok I could need 1 tester for a "pre-alpha" build. best case: He / She has bought the 70D in 2014. You won't be able to remove the bootflag again. Just drop me a PM or take a look in IRC...

Update: Let's say I need 5 testers. If you already got some dev knowledge and have no problems with compiling ML then don't hesitate to PM me so we can run a few test days before making anything public.

We'll see.  If I spend my time figuring out how to upgrade the SD slot and (only if it's possible) writing up a detailed tutorial, I'm only helping myself and a few other brave souls willing to perform surgery on a $1000 camera.  If I spend that same time trying to figure out how to write files from the camera out the USB port, and I'm successful, I'd help a whole lot more people.  I don't have much time for either one for at least the next month, and when I do have time, I'd sooner investigate the USB idea.

Great work @nikfreak -- PM me if need a beta tester on the 70D otherwise I'll be happy waiting until its release.

and yes there are different ICU's in each 70D regardless of which year it was made. Mine was from early 2014 I believe (or late 2013 but will double check) which didn't work during the small "Hello World" testing several days ago.

The newest ICU release date is about 25th September 2013.

But there's also one from July 2013 installed on some cameras.

Patience is virtue!

Title: Re: Canon 70D
Post by: walter_schulz on January 07, 2015, 05:01:38 PM
What.
A cam with bootflag set will look for a bootable card.
If a bootable card is found the cam will load Magic Lantern. If the files are there.
Formatting a card using a cardreader and PC/Mac will produce non-bootable cards.
If no bootable card is found the cam will just start. With a slight delay. And this delay will happen leaving powersafe, too. We're talking about 1-2 seconds here.

It won't really matter. we are going to support all known fw revisions (till date there are 2 of 'em). But first let's make one (the one I am working on) stable. Stubs are well documented and we will be easily able to match the differences

Looks like the 70D VAF has just recently arrived, right in time for the ML port release! Good timing! Can't wait to see what kinda footage I can get with both ML and the VAF  :D

DERP.

Speaking of the VAF though, does anyone know if it has a different impact on ML raw footage compared to h264 footage? I'm not exactly sure how the Mosaic Engineering VAF works, and I'm not even sure I understand the differences in the way the sensor is read between raw and h264, but I know recording raw reads only 1 of every 3 vertical lines and recording h264 does something different.  Which makes me wonder if the VAF alters the image differently when recording raw?

I think the idea is to keep it on the down low till bugs are exterminated or people will complain.

As well they should. People will try it and complain when they soft brick their bodies. Best keep it under till alpha.

On the T4i the pre-alpha was rock solid for me, for what I was using it for, but I'm asking a lot more from the 70D as are most. Let's just back up our devs while they do what they can to bring ML to life for the 70D.

Post by: emvee on January 08, 2015, 10:16:37 AM
Sorry if this sounds like a newbie question, but just so I'm clear, is the reason that the 70D won't be able to record RAW video at 1080p because the SD controller can only write at around 40 mb/s and RAW requires faster writing speeds?
Title: Re: Canon 70D
Post by: walter_schulz on January 08, 2015, 10:26:49 AM
Yes. ML RAW/MLV writes uncompressed data.
Write rate (Byte/s) = Vertical pixel/resolution * horizontal pixel/resolution * 14 * frame rate / 8

For [email protected]:
1280 x 720 x 14 x 24 / 8 = 38707200
about 37 MByte/s (24 is not 24 ...)

For [email protected]:
1920 x 1080 x 14 x 24 /8 = 87091200
about 83 MByte/s

Actually you can record 1080p but only for very few frames.

Sorry if this sounds like a newbie question, but just so I'm clear, is the reason that the 70D won't be able to record RAW video at 1080p because the SD controller can only write at around 40 mb/s and RAW requires faster writing speeds?

Correct, but that's only 1 of 2 reasons.  The other reason is the sensor.  Due to the way raw video is recorded (reading only 1 of every 3 lines) the maximum resolution you can read from the sensor is 1856x1044.  So even if it had a CF slot that could write 100MB/s, it still couldn't shoot full 1080p.  Which sucks, because the video these cameras shoot is already pretty soft, upscaling it will make it even softer.

Speaking of that, I wonder if the 3x crop mode will allow the full 1920?  It wouldn't matter for this camera, but it might matter for the 7D Mark II (same sensor).  If so, you could use a really wide-angle lens to get a full 1080p image at a reasonable FOV.

So will this ML be able to override Canon's 29:59" recording limit? They have it programmed so it can't record any longer than that.

I really wonder how can Canon put some much limitations to its cameras when they have the Panasonic GH4 as a competitor !  ::)

Canon owes the ML devs a ton of money.  If it wasn't for ML they would surely lose a lot of sales to their competition.  Right now, the 7D Mark II and GH4 are only $100 apart, and with the 7D2's lack of ML, the GH4 craps all over it.  Even with a ML port the GH4 is probably still the better deal.  I've never bought a camera over $1K but if I was choosing between the 7D2 and GH4, I'd unfortunately probably choose the 7D2 purely because of the investment I've made in Canon lenses.

Look at this: https://www.youtube.com/watch?v=nH5fafQQddg

If you ask me, I'd say the compressed GH4 footage still looks better than 5D3 raw, and obviously destroys the compressed 5D3 footage despite a bit rate that's only slightly higher.  Canon's compression is so disgusting, you'd think in a 1080p YouTube video, 91Mbps 1080p footage would look better than 100Mbps 4K footage.  But no, the GH4 can record 4x the amount of pixels at almost the same bit rate with much better detail.  And not to forget after all that, the GH4 literally costs half of what the 5D3 costs.  The only advantage the 5D3 has is sensor size.  If the 5D3 didn't have ML? lol.

Yes, I understand the whole "cinematic" argument but IMO it's easier to soften in post than it is to sharpen.  Removing detail will usually work better than adding fake detail.  Still photography is a whole different story, and obviously DSLRs are made for photography first.  But I can't advise any aspiring videographer to choose any Canon camera over a GH4 or a Black Magic or a Sony for video production.

Post by: AntoineLavenant on January 08, 2015, 05:23:02 PM
DigitalVeil => Yeah, totally agree. Right now, to me the lenses are the major argument for Canon. Sometimes I wonder if I should sell my 70d+lenses and go to a gh4...
I already saw some comparison of gh4 vs 5DmkII and it's crazy how sharp the gh4 is.
Still love my 70d and thanks to Nikfreak work, it will soon be a lot better !  :D

Post by: GARoss on January 08, 2015, 07:56:21 PM
It's hard to argue against the GH4 for video. But, certainly an argument could be made for the 5mk3 for photography. They are different animals. In this case you can't have your cake & eat it too. I wish that wasn't true but it's not.

I take vastly more photos than video. That's why I bought the 70D with hopes ML would bring RAW video to it. That would be having your cake & eat it too.  ;)

Ive been biting my tongue. But here goes a little bit.

Ive seen great video shot on a 550D, h264, and with very little gear.  Check out the link, and "Portrait of Macerata" clip at the bottom.  The other clips he explains how he did it with very little gear.
http://philipbloom.net/2013/09/13/part3/

Ive seen great video shot with a 600D, H264 with just a monopod as in the clip bellow.  Thes guys have a whack of tutorials on how to shoot cinematic with DSLRs.
https://vimeo.com/51671122

Ive seen great video shot on a 60D in H264.
https://vimeo.com/15529823

So aps-c H264 is extremely competent.

Dont tell me the 5DMIII is crap compared to a GH4.  The GH4 is a different tool.  You can shoot 4k also on a galaxy not phone camera that's sharper than a 5DMIII ... so what?
Cinematic film, rarely needs a 4K sharpness infact most cinematographers soft focus more often than sharpen for film. 
The skin tones on a GH4 always suck, and its bokeh is ugly.  Its just not that kind of tool, its well lit master shots are great. Its DR in the well lit master shot is great.
You can crop it in post great.    The 5DIII bokeh, low light noise, shallow DOF, RAW colour, are all fabulous with right glass/skill. 
And for general 35mm film, the aps-c sensor size sensor is the king, its what's in a RED ONE. 
Film set guys complain about the FF cameras, because the DOF is so shallow, it requires a lot of takes to nail it.
You want to get it done, an aps-c camera is your bread and butter.   
I like all three of these 70D, GH4, and 5DIII but each for its own strength, neither does it all. 

Walter is right, sorry for tangential stuff.

That Comparison sucked, and call me crazy but the second shot inside the shade looked like the 5D was sharper and had more detail overall.  Yes the GH4 shoots 4k but that doesn't mean its good at it.  I would gladly take the 5D Mark III RAW Video and High ISO performance over the crappy High ISO and Highly Compressed footage from the GH4 not to mention the crappy Lens lineup too. I was surprise Dave Dugdale sold all his canon gear to shoot GH4 and A7s.  It makes no sense,  RAW gives you so much more Possibilities in post.  Only thing you can do with the 4k Footage is crop.

IMHO you couldn't be more wrong there, I've just bought a GH4 after shooting ML Raw and i'm very impressed, I can see why with a speedbooster Dave Dugdale did what he did. The high sensitivity performance is not bad at all, it is average, alot better than any canon bar the 5d3 1Ds and 6d. With the correct curves in camera and careful exposure the amount of latitude in post in very very good. I've tried a 70d, it was like digging up the garden with a small trowel and a broken wrist as a opposed to the JCB that is the GH4.

Detail and sharpness in a 5D image is deceptive, Your probably looking at aliasing and god knows what other nasties, I doubt that's real detail.

Yes the GH4 is compressed, but its done so well the resulting image if your doing it right is truly stunning, my mouth dropped when I pulled out the card and watched on a nice display after my initial test. I also love not worrying about batteries getting killed and changing 64gb cards every 15 mins, in fact its bliss.

But there's still a place in my heart for the canon raw, it is such a nice image in every department other than the aliasing and rolling shutter issues.

But don't kid yourselves folks, IMO as a video camera goes, the 70d does not hold a candle next to a GH4, sorry.

I'm far from wrong,  You're comparing JPEG vs RAW.  RAW will always be better and i would NEVER Shoot JPEG even if i was running out of space.  Correct me if i'm wrong but did you just say the GH4 is better than the 5d3 1Ds and 6d ISO performance?  The 6D and 5D Mark III Blow away the GH4 in Low Light.  GH4 vs 70D High ISO would be a more proper Comparison to which the GH4 is a tiny bit better.  Yes Video Compression is getting better but the point is, it's still compressed,  You're still limited regardless but if you shoot in RAW,  You gain a lot more Data to play with let alone sharpness. 4k Video is not a standard yet so until then it's almost pointless.

I did buy the 70d as soon as it was released and has been missing Magic lantern ever since, coming from a hacked 600d.

I also own the gh4 , gh2 (hacked) and a hacked dmc-gf3 (basically a mini gh2). All of theese cameras has got better video compared to 70d , in terms of sharpness and detail. But the touch focus and the image quality on the 70d is still nice and very capable of producing nice images. Hope this will even get better With Magic Lantern.

Among the testers of the early 70D ML, Has anyone succeeded in using the focus peaking ? I'm very interested by this function.

Another thing : Could it be, at least theoretically speaking, to modify the AF properties in video ? For example its speed; Dual pixel af is very fast, but sometimes it's even too much. If it was possible to make it slower, it would allow smoother focus transition in this mode.

For example I find the focus transitions of the GH4 AF much smoother : https://vimeo.com/96882002

Of course the GH4 is not as accurate as the 70D for continuous AF, so we can see in the vid that the GH4 af sometimes goes forward and backward the subject, but transitions are still a bit smoother due to its slowness.

Considering that the sensor phase detection turns down the speed in video compared to live view, I'd say that might be entirely possible. We'll see.

I think there're a lot a new possibilities with this 70D, even if it is limited by the use of SD cards for RAW video, compared to 7D's/5d's. I often need to edit my videos really quickly, and RAW needs too much time and a more complicated workflow compared to H264, so shooting in raw not my main concern for the 70D. But still an amazing thing.

If all one needs is say 15s raw clips for master shots, sunsets, wide angle shots of the beach etc.  then 1792 x762 will do just fine.
The kind of clips X-state has been posting.  Itching to try 3X crop, and see the max. res for 10s (that's about all one needs in a master clip).
I think RAW is waaay over used by some,  too rich colour (even if its 14 bit raw) can make a person look like Barbie.

I just attached my loupe sheet to my 70DLCD. Had to poke out the screen cover to get touchscreen access.
Next up is to cut into the bottom, ever so carefully for a finger access.  I'm getting ready for MF lowlight raw.

Canon's h264 is so gross (to me), especially at the default bit rate.  3.0x is not much better, but it's still a slight bump (and hopefully ML is updated to remove that limit at some point as 20.0x has been done on the 7D).  I feel embarrassed doing paid gigs with h264, but it's all I can manage on my limited budget right now.  14-bit raw is truly awesome, I really hope we can figure out how to write footage to attached USB storage, that could theoretically raise the max write speed to 55-60MB/s with dual writes, which may be just enough to get squashed 1856*xxx at 24p continuous.  Otherwise maybe I'll have saved up enough for a 7D Mark II by the time it gets an ML port (although I'm not so sure I wanna stay with Canon)

Ok so for those who want to use a big LCD screen for focus check/set while shooting ML raw, here is my loupe hack.
- permits touchscreen access, and the loupe, good for both AF & MF without removing the loupe.
Recall
the HDMI outs blanks the LCD - so you loose touchscreen AF when used
the usb solutions of DSLR controller App on Android or EOS utility on Windows/MAC does not work with ML raw.
So my approach is one option that works and keeps the 70D touchscreen access!

Hi everyone,

Sorry in advance if my question is already answered somewhere else. But i've been searching the web for days and have not found a solution. Magic Lantern is new for me too. And as always, there suddenly a rush to have answers :P

I'll just state my issue first: I'm an amateur photographer who has more experience as a video-cameraman. I'm starting to use my 70d for video now and there are a few bumps I would like to take. Foremost; i'd like to have the equalizer/audio levels in my screen and be able to listen to what i'm recording. As I understand after reading here, there is not yet a full version ML for the 70D and controling the recording level for a mic is not possible, and it's also quite complicated to plug in a minijack for headphones etc.

The video below was confusing for me: The uploader has an option in the bottom left when in M and in movie-mode, and he can atleast see the levels. No matter what I do, but the option is just not there for me, it's blank, and he's dradding the levels with the touch screen too wich I thought was impossible. See from 2m40

When set to manual, the levels are indeed shown in the screen. I understand now that when you press [Q] in de live-view screen you can drag the levels as desired wich is easyer than exiting the videomode, go to settings, adjust and go back to filming. But during filming it's not possible.

Hopefully ML will make that available in the near future :)

I made a RAW vs H.264 video, I think its a big step up! Make sure to hit that HD button.


Yup, the difference in detail and color is unbelievable, even after YouTube's disgraceful compression.  What resolutions did you shoot for both the raw and h264 clips?

Also, speaking for raw, random noob question: Is raw video 4:4:4 or 4:2:2?

Yeah, as we saw on other canon cameras, the difference between h264 and ML RAW is amazing.  :D
Really looking forward to working with it !

I would also be interested to know in what resolution you shot these and also if you applied any color correction, noise reduction, etc....

Thanks a lot for your video anyway (y)

I still wish we could just "cut off" the 2 or 4 least-significant bits when doing the EDMAC copy from sensor to card, I'd definitely exchange some depth for some increase resolution  :P

Although I guess if you do the math, even lopping off the last 6 bits still needs over 45MB/s for 1856x1044 raw, and 8-bit sucks for editing...

DV " Is raw video 4:4:4 or 4:2:2

14 bit raw refers to the sensor data.  Each pixel is 14bit of information.  When a CODEC is applied, it converts/compresses this to 4:4:4.  H264 compression is generally 4:2:0, which is the delivery standard.
Adobe raw codec works with 4:4:4.  The big difference in the 0 vs 2 or 4 is in the colour range/granularity which the human eye is really not able to distinguish that well.
Again the goal is to export your final delivery in H.264 4:2:0 as that's what most TV's are (I thought 4:4:0 for tVs).  That's my limited understanding.

The less detail in the shadow areas of an H264 is a direct consequence in how it compresses.  It tends to provide detail in areas of light, and compress harder in less lit areas.
That's why shooting flat & ETTR is so important with H264 as you want to maximize detail in the shadow.  I dare say that many of H264 vs RAW tests, are so different because
they did not take the kind of care needed to get the most detail in shadow from H264.  Also using lights creatively helps to retain shadow detail inH264.

Look at the videos in my I bit the tongue post at some of the stricked out video links, and you can get a better idea of what H264 can do, when handled well.
That said raw video, does have more information and when equally well handled provides more creative options (and needs less lighting kit).
Yes raw is better to capture/edit in but at a workflow/time increased cost.

Do you mean 4:2:0?  I haven't heard of 4:4:0.  But yes 4:2:0 is fine for your final product as you wont be altering the image anymore.  For editing you definitely want 4:4:4 as that gives you way more flexibility to color grading, effects, and other alterations.  Editing a 4:2:0 clip too heavily can quickly turn it into total mush.  I was just assuming ML raw was 4:4:4 because it's just a straight copy of sensor data, but I wanted to confirm whether it was or not.

Also, what's considered a dangerous temperature for these cameras?  My 70D has regularly been reaching 70-80C while running these early alpha builds, I don't think my 700D has ever gotten that hot.

Yikes.  You mean turn the entire LCD off? Kinda need that  :P  I wonder if it's ML making it hot or if my particular camera just runs hot, because I did a shoot with it a couple weeks ago (no ML obviously) and it got very warm in my hand just shooting h264.

Regarding your first question, for what it's worth, I can get around 5-6 seconds at 1856x1044 (16:9) 24p before recording stops.  Haven't tried anything else yet, but I'll see what I can get for 10s at 2.35:1

Specifically around ~135 frames, so closer to 5s at 24fps.  Not too great.  Lowering res will obviously grant a few extra seconds but at that point you might as well drop down to something sustainable.

What walter said.  Wireless N is dependent on the number of antennas, the 70D probably only has one (based on Canon's defining 150Mbps) and that's only achievable without signal interference, which is the other problem.  Even if it could transfer at 600Mbps, wifi is easily interfered with and rates fluctuate.  It's nowhere near reliable enough for writing video files in real-time.

Longtime lurker, first time poster. Have there been any discussions about ML and the 70D and re-enabling wifi during video? It would be nice to use an iPad as a monitor, especially for touch focus pulling  :)
Title: Re: Canon 70D
Post by: ShootMeAlready on January 13, 2015, 05:59:52 PM
6ft - Wifi for video would only work with H264.  Hardly worth the effort when you can buy DSLR controller app for $8 and put the Android tablet/Smartphone in the hotshoe via usb.
The wifi for ML shooting raw, is hopeless because of what Walter said.  TX rate to low.

There are a number of wifi solutions for DLSR controller app, but its Android.

@bigorna - Hi there!  That's why sixfootgeek was asking; to find out if ML could enable this feature.  That's a big part of ML; enabling great features that Canon has otherwise crippled.

@ShootMeAlready - Howdy!  Everyone has there own purposes and techniques for their individual needs.  I know a lot of you are mainly only interested in RAW video.  But for others, the ability to setup the camera for video and remotely control it from 100 feet away via WiFi, would be a highly sought after feature.  :D

That's right. If it is something that is not limited by the hardware, maybe it can be enabled by ML...

Yeah enabling wifi during video would be great, even if its only with H264, really helpful for the ones using steadycam for example, it would allow to use the touchscreen functions without having to actually touch the camera and unbalance the whole thing.

I don't see why they would disable something like that if there wasn't a hardware limitation.  But I guess it's worth looking into as it would be extremely helpful for situations like that.

Yeah I assumed wifi with video took too much power or processor speed or heat but maybe at 720p it would be fine. I guess I'll hope canon only wants it on higher end models and it's a simple tweak.

Was the 100ft wifi comment an exaggeration because even with clear sight my reception isn't close to that far. Maybe there is a way to setup a repeater or something.
Title: Re: Canon 70D
Post by: TechnoPilot on January 14, 2015, 04:41:29 AM
Honestly, if you want WiFi with video, just buy a TP-Link MR3040 and install the DSLRController firmware onto it.  It is a far more power and faster WiFi device then what is in the camera and it is far easier to use! I'm sorry but what Canon implemented for WiFi in the camera and the cludgy interface they made to set it up is sadly disappointing, especially considering they had a touchscreen to work with.  I tried the 70D's WiFi function a couple times and compared it to the TP-Link, onboard WiFi could not even give me smooth consistant framerates in liveview when in hotspot mode, the TP-Link always does even in some pretty RF saturated environments.  The only time I found the camera would give decently smooth liveview over it's own WiFi was when I made it join my home's local network and then connected to it with DSLRController.  Plus with the TP-Link it is as easy as plugging it in and turning it on independent of the mode you are in.  For video work, it is always on my camera, mounted off the side of my hotshoe next to the mic.

Now if only ML and the guys from DSLRController could make them function together, then we would be seriously cooking! But we are getting into a relm outside the discussion of this thread.

JG , there are some wireless usb solutions that are not android, but that assumes you have an app on your ipad that works via usb.
The DSLR Controller app is significantly better than EOS utility.  I have yet to read of any decent ipad app that competes (in price, function or value).

TP that's one sexy lady, it peaks my gear lust.  Did you polish it up? It looks too clean (there's no drool stains, paw prints, or claw marks). 

TP I though TP-link is just a router, so how/where do install an android app on it?  Is that the special wifi version of DSLR controller app? Dont you need a cpu & storage to run it?

16:9 no-stretching: 1280x720
16:9 1.4x stretch: 1536x864
2.39:1 no-stretching: 1536x642
2.39:1 1.4x stretch: unsure, will update

All of these are assuming 24fps and an SD card that never dips below 40MB/s, not even for a moment (many SD cards, despite being advertised to write way beyond 40MB/s, will experience random drops that could stop your recording or result in frame skipping).  By 1.4x stretch I mean recording a squashed image and stretching it vertically by 40% to get the listed resolution.

@ShootMeAlready - That is just what the glorious Sigma 18-35mm f1.8 Art looks like out of the box, I honestly can't say enough about how this is the perfect all around zoom lens for the 70D that is available right now for both photography and video.  I have compared what I can get out of it directly with shots taken by a friend of mine who is running a 5D mkII and dropped more then I paid for my body and this lens on the new Canon 24-70mm f2.8 USM II and the Sigma 18-35mm Art matches his setup for not only sharpness with actually the same preceived megapixels, but also for actual depth of field and low light performance, yet focuses better and has a less vignetting and even a little less chromatic aberration.  I was blown away at how well this not only matched up to his setup, but actually out performed it.  The only thing I could do with is a little more reach then 35mm so it actually equated to 70mm, since the 35mm only gives you an effective 56mm.  Honestly though I don't really care, I'm in gear lust of my own setup with this, here is another shot of it below for fun! :)

(http://tapatalk.imageshack.com/v2/15/01/14/04e27153bfd586bfddfe8a57e19d77a6.jpg)

Now as for the TP-Link, it uses a specially configured flavor of the open source router firmware OpenWRT available here  http://dslrcontroller.com/guide-wifi_mr3040.php  (http://dslrcontroller.com/guide-wifi_mr3040.php). Just ensure you use the correct revision for the MR3040 that you purchase as they had two revisions if I recall correctly.

Anyways I wanted to answer your questions, but we should keep the discussion here to the ML port to the 70D.  Please feel free to message me privately if you or anyone else has any questions.
