Thought I'd check in on this today.  Not that I expected there to be any news on this front, it's just still disappointing this camera most likely wont get ML when it has so much potential.  Oh well

If there hasn't been anything posted on the progress of it in weeks, I think it's safe to assume it's dead.  At least for the time being.

Anything ! :-\

Don't hold your breath, if it ever gets ML (and thats a big IF) it wont be for quite a long time.  I don't think anybody is even working on it at all right now, save for maybe Alex spending a little time in QEMU here and there. An ML 7D2 would likely be the best ML cam since the ML 5D3, probably even better, so of course there is incentive.  But ML development isn't what it used to be, it's more about maintaining the cameras that already have it at this point.

By the time ML is ported to the 7D2 the camera will likely be a whole lot cheaper, at which point it will be a great cam to get.

Looks like it will take a while? More like it looks like it'll never happen at all.

I wouldn't hold your breath for it.  ML development is extremely short-handed these days :/

Holy crap!  I've been away from this forum for a few months now and I gave up hope we'd ever seen ML for the 7DII, but I checked for a new 70D build today and saw this!  Amazing news, the potential for this camera is insane.  I know a port is still a very long ways off, and not even a sure thing, but to see any progress at all makes me really happy!  Right now things are kinda tight financially for me, but I'm gonna try to pony up some cash to donate.

7
The bottom line is: we know how to do this, and it would work, but it is a lot whole lot of work to implement, and might not be worth the effort (compared to what could be done spending that time on other things like FRSP for example)
I might be a bit misinformed regarding FRSP...but how does FRSP improve video capabilities on the 550D and 600D? ... I don't see how this would improve video quality on the lower end models.

Both of these things could actually work together and be extremely worthwhile for future Canon DSLRs with USB 3.0.  It's maybe a longshot, but something monumental could be accomplished on the 7D Mark II with both FRSP and USB writing combined: "5K" raw video.  Obviously, the 7D2 is the first Canon DSLR with USB 3.0.  It also has a CF and SD slot to go along with it, which together can reach a combined ~175MB/s.  USB 3.0 in the real-world can reach at least 400MB/s (if not more when there's no encoding).  If you could span files across all 3 interfaces (not sure more than 2 is even possible) we're looking at a theoretical 575MB/s (or more) possibility.  If it's limited to just 2, USB+CF is still 500MB/s which is crazy.  Now, I don't remember what the max speed of the EDMAC is (500MB/s?) nor have I calculated the speed required to readout a full 20+ megapixel sensor at 24fps continuously, but I think you get the point.

As it has already been established, it would require a huge amount of collaborative work, and maybe it's not worth it for older USB 2.0 models, but I think it could allow for some incredible things with the 7D2 and future Canon models.

8
60 MByte/s for USB 2.0 is just theory. In practice you will have less. USB 2.0 is known for terrible protocol overhead and you will see only few devices reaching 40 MByte/s.

Yeah I rarely see USB 2.0 transfers reaching even 30MB/s.  But that's pretty good if you're adding it to the existing 40MB/s via dual-writing.  And as g3gg0 just said, faster is possible under the ideal circumstances (like no compression).

As far as my own experience, usually Windows reports the exact transfer rate to me while a file transfer is in progress, but for some reason it wont tell me when copying from camera to PC so I had to hand-measure it.  I was able to copy a 1.13GB h264 video from my 700D to my SSD in ~45 seconds.  In base 2 definition, that's 25.89MB/s.  Of course there's going to be some human error in hand-measuring, but it's definitely at least 20MB/s.

yeah its honorable.

but we have thought of so many things we could use to write at higher rates.
its not about "connecting edmac a and thing b and we are done".
its about massive work to be done

Right, I didn't expect that it would be some easy task or anything like that.  I was first and foremost wondering if it was even a possibility.

9
Trust me, if I had the financial resources, I'd own one of those cameras.  And if my programming knowledge was more advanced, I'd do it myself.  Just trying to see if there's anything left to squeeze out of these DSLRs.

10
if it ends in such a split-file-combination you just raise the upper datarate-limit - but it cant avoid copy/merge-orgies. and it wont(!) give advantages for storage size, its just an option on top. the main speed is still on the cf-card.



Every bit of speed counts, especially with these SD-slot cameras  ;)

Hi! Welcome.

1. As long as your card can write (not just read) above 40MB/s, you're golden.

2. The bitrate of 720p raw is wayyyy higher than the default compressed 1080p (like 6x higher) so yes, much more information is being recorded as far as dynamic range, color range, and detail are concerned.  Unfortunately I don't have a side-by-side comparison to give, but personally I'd say raw 720p upscaled to 1080p (or even just left at 720p) looks better than Canon's h264 1080p, especially considering the extra flexibility you get in post. HOWEVER... you're not strictly limited to 720p.  Obviously going from 16:9 to cinema-standard 2.39:1, you can get higher resolution.  You can get at least 1504x630, possibly even 1536x642.  In fact, you can go even higher than that for short clips (maximum for the 700D's sensor is 1728 wide).  The higher the resolution, the shorter the clip you'll be able to capture before recording stops. 

But that's not all - if you go into 1280p60 mode (through the Canon menu) you can squash your video vertically, sacrificing vertical resolution for extra horizontal resolution.  In "squashed mode" with 2.39:1 aspect ratio, you can record at the maximum width, 1728x516 24fps continuously, and then stretch your footage vertically by 1.4x in post to get a normal-looking image.  You can even go up to 2.20:1 aspect ratio with 1728 width and 24fps before hitting the 40MB/s limit.

3. For future reference, in the raw capabilities chart linked by Rshred, the 700D is identical to the 650D in most respects.

4. The "pink grid" you are describing is a well-known problem with every 700D and 650D, your camera's not broken.  Those are "focus pixels" use for AF and current there's no way around them, but they can be removed.  See my post here for instructions on how to remove them: http://www.magiclantern.fm/forum/index.php?topic=14218.msg137317#msg137317
(short version: use raw2cdng with chroma smoothing 2x2 enabled).

5. As far as the "flying red dots," I'm not sure I've ever heard of that before.  Could you possible show an example of this?

12
I'm curious if it's at all possible to write raw video files out through a camera's USB port directly onto something like a USB flash drive, something like having the EDMAC copy the sensor readout to the USB controller instead of the SD controller.  Of course, all current ML-supported cameras have USB 2.0 or slower, which in real-world situations tops out around 20MB/s, so this feature would only be practical if it were possible to dual-write to both the SD/CF and USB port at the same time (same way the 5D3 can dual-write to both CF+SD at the same time).

I know this idea has been kicked around here from time to time (like here: http://www.magiclantern.fm/forum/index.php?topic=6128.msg57345#msg57345) but it's never really been seriously pursued.

If this could be done, it could provide a pretty significant boost to all cameras (at least 2.0 models) in terms of raw recording capabilities.  Cameras like the 650D, 700D, 70D, and EOS-M could theoretically write up to ~60MB/s.

Looks great! I'm actually going to be doing this exact kind of thing soon, hip-hop music videos, and I'm trying to be creative and do them differently then most lame generic rap music videos made these days, this definitely gave me some inspiration!

And yup, YouTube's compression is disgusting.  I hate the way it violates beautiful footage...

Hi guys. I want to also report, that after tweaking the MP menus around 5-10 minutes, I felt my camera hot in my hand, when I looked to the temp counter it was 80 degrees. That is too hot. I see the next update will alleviate tis problem to some extent, but I wonder, why is it happening? What is the ML menu doing? It is not like it is recording video during the menu operations?

It's not actually 80 degrees, ML is reporting the wrong temperature.  It's being fixed to report the real temperature.  I think the 70D just runs hotter than other cameras, mine would get just as warm to touch even before ML, ML is not making it hotter.

Another question (valid on every ML version), if you success to record raw video and change the fps rate, the video size, the debit in H264. Isn't possible to take 1080p 60fps or 1440p video ? The captor, buffer, card speed and even processor are enough to do it no ?

No.  http://wiki.magiclantern.fm/faq#troll_questions

There's a hardware limitation and a long technical explanation that isn't worth typing out.  Trust us, it's been tried and it's just not possible.

Please read the FAQ and guides and use the forum search tool before posting questions, you'd be surprised how often a question has already been answered elsewhere.

Raw_rec works good. I shot with 24 fps (screen resolution - 1600x800) for 30 seconds. With the screen resolution 1344x672 my 70D works with no time limitations.  My memory card is SanDisk Extreme Pro 95 MB/s 64 GB. My test-shot is here: 
Thanks a lot for your work!

Nice video! The raw footage really puts in perspective just how soft the h264 footage is.  Can't stand that softness.  I also found it very interesting how switching to raw almost completely eliminated the color aliasing in the 3rd shot.

Hey guys, can anyone confirm, if the dual-pixel focus thingy works when shooting RAW?

Yup, dual-pixel AF works when shooting raw.  Currently no AF box, but it still focuses where you touch.

People, Does this raw has Pink dots ?, I know there are ways to solve that, but does this has ?

No dots, clean image.

Tested raw in 720p60 mode and did indeed get a video height of 434p, which means squashed raw will need to be stretched by ~1.66x.  I was kind of hoping it would be 1.4x like my 700D, but on the bright side 1.66x does allow us to shoot 1856px wide in up to a 2.20:1 aspect at 24fps continuously.

(and not the crew who can't follow instructions and are surprised that canon stuff is made in japan! with firmwares!....but anyway, if you don't want to take a picture when you need to reset the metering, mount the card and write/flush the buffers ie straight after the firmware-sensor clean...don't...same as if you want to burn out your camera early keep running full res raw on alpha code, that'll work)

Look, you really need to watch yourself with the talking down to others.  Almost every post you've made so far has had some sort of condescending tone to it.  It's not at all constructive or useful, and to be frank, you're a forum newcomer with a total of 5 posts.  You haven't exactly earned the right to speak to others that way here, if there was such a thing.  Good for you that you are an admin elsewhere, but you aren't one here.

Your method of installing this build worked for you personally, but that's actually not what nikfreak's original instructions specified.  They simply said to have at least 1 picture on the card before running the FW update, there's nothing about snapping 1 picture right after the FW update (look again if you don't believe me).  Glad to hear that worked for you, but as you can see in this thread, not all 70Ds are the same.

Confirmed this morning that the FPS (set to 24 on the canon menu) is locked at 21.576 and deviates +/- .002 FPS during recording. I'm sure there is an issue with the algorithm that regulates frame rate, @Nikfreak, I looked through Raw_Rec.c and couldn't find the part that actually controls frame rate/how data is recorded to the SD card. Is it in another place?

EDIT: I found fps.c, am looking through it now.

Yeah you wont find anything that controls fps in raw_rec.c.  I've given a1ex the FPS timer values and he's already working on a fix.  However, your camera is probably still recording at the FPS value set in the Canon menu despite what ML says.  Are you getting the 21.576 from the ML overlay or from the actual file information?  When I go to 1080p24 mode, ML EVF says 21.576 but my raw footage still comes out to 23.984fps.  Haven't tested any h264 though.  I am running a slightly earlier build that includes FPS control but I leave it off when not looking for timer values, so it shouldn't be any different from Alpha0.

EDIT: Maybe not?  Just tested raw 60fps and got the 53.976 specified in the ML EVF.  So maybe FPS is screwy even when FPS Override is disabled.

   Are you sure about that 80ºC ~ That would be 176ºF & you would not be able to hold it If So ~ I have Run My70D in Mov'Mode for up to @Least 8Hrs stopping only a few seconds @ the 30MinMarks & whenever it needs a Batt' or Card Change & it does get VerySlightlyWarm in the Batt' & Card Area with the Card getting the Warmest ~ But Even the Cards never get anything more than just Warm ~

                                                                                                                                                             ORR ~ DeanB

It's just the temperature ML is reporting, which could be wrong for all we know. And it's the internal temperature of the camera, the exterior shell will always be cooler. I think I did read in the 70D manual that Canon actual recommends not holding the camera in your hands while shooting video as it can get hot. Idk, I guess that's just the way it is.

Hello,

Thanks a lot for your great work!
Before trying this new ML, i'd like to be sure there's still an Advanced Bracket ( as i only make HDR photos )


Regards,
Vince
Unfortunately Dual ISO is completely non-functional at this point.

I'm getting the same temp, but it doesn't feel any warmer than usual, especially around the SD card slot, which usually gets hot. It stays warm (cooler than usual) even when recording 1600p 2.35:1 Raw for 3 minutes.

Hmm... well at least I'm not the only one.  The camera would get quite warm in my hands even before ML and I suppose it's not any warmer than it already was.  I guess these things just run hot?

4) the 70d does NOT go automatically to playback mode, yet it operates normally like if I didnt update or touch the firmware. pressed playback, took pictures, but does NOT show " bootdisk enable ", even waiting for a few minutes with screen on playback mode.

Did you have a picture on the card before running the firmware update?  That might be the problem.  When I do the installation it doesn't automatically take me to playback either, I had to press the play button manually and wait a couple seconds.

Also - sorry this is a little OT - I noticed in Canon's menu that my lens has its own firmware, and there's an option to update the lens FW.  It's the new 24mm f/2.8 STM pancake.  I had no idea a lens could even have firmware!

To anyone who is running this build on their 70D:

What does your camera temperature (on the ML overlay) get up to?  My 70D gets up to about 80C after ~10 minutes of usage (in either LiveView or Movie mode) every single time I use it.  Even when not recording.  I'm wondering if ML is causing my cam to get so warm (doubt it) or if it just always gets that warm, and whether that's common for 70Ds or just a problem with mine.  I'm betting it would overheat during an outdoor shoot in the summer...

Another strange thing :

shutter speed value shown by ML in video doesn't match with the value shown by the LCD screen on the top of camera :

ML shows 1/27 when camera says 1/30, then 1/32 for 1/40, 1/40 for 1/50, 1/50 for 1/60 etc... like if there was a gap of one stop between the two, is it normal ?

Not normal, but it's a known bug

-HDR video : don't know how to activate it, asks for manual iso.

Yeah I forgot about this one, happening with my build too.  Features that require manual ISO will claim that manual ISO is disabled even when it is set to manual.

Also, I reported that the flashing zebras were fixed but I was wrong.  They stop flashing when AF is disabled, enabling AF causes both zebras and spot meter to flash on and off.
