I don't know if it is appropriate to say it here, but after upgrade to 7D's latest firmware 2.0.5 from Canon, I was no longer able to boot into ML, the camera was just dead. I had to  pull the battery for 10 seconds to revive that thing (without ML card in it). I deleted the ML directory and autoexec.bin from the root directory, but still could not boot with the camera, so the only solution is to format the card before put it into the camera, but I have loads of photos and movies in the card which I don't want to delete for now.

Any remedy? I am not sure downflash the camera to earlier versions would help.

So prewarning: if you want to keep ML on 7D, don't flash to Canon's firmware 2.0.5.

Does the camera boot without the card?
If you don't want to lose the files off the card but still want to format just back them up on you computer and then put them back in after a format.
Why did you bother updating to 2.0.5? the update doesn't really add anything unless your planning on transferring files wirelessly.

Anyone can use ML, is open. What kind of moderator are you?
Moderators are polite and educated.
Contain yourself my "friend".
Kick me if you whant, but we no deserve this kind of attitude, even if it comes from a moderator.

Firstly the 7d version of ML is still in alpha, he is correct when he said that you probably shouldn't be using it as there are bound to be issues that will require you to have advanced knowledge in post production, RAW itself requires a hell of a lot of knowledge itself.
Not sure why people act as if they paid for Magic Lantern, everyone needs to remember that the devs here give this to you for free, we should be thankful not demanding, do not act like the devs owe you something or should be polite in any way.

I do most of my work in after effects, a lot of people on this forum seem to spend a lot of time converting and resizing footage in other software to make it compatible which I can understand your frustration if that's the case as it can take a lot of time, it's why I recommend AE as it's as simple as importing the DNG sequence and scaling it up by around 11%, it literally takes a few seconds to do and works perfectly.

[Prepare your CF card]

Hey guys having an issue with the new builds.
Original had an early build from back in August on my 7D that I put on using the process in this post http://www.magiclantern.fm/forum/index.php?topic=7464.0
Just tried out the new Nov11 Tragic Lantern build and it loads the first time after I do a firmware update but the next time I load it freezes the camera and I have to wipe the ML files and replace them to make it work again.
Anyone have any idea what I'm doing wrong?

Are you using a new or different card, make sure you have done the Prepare your CF card section on that link you sent.

Hi, just installed ML from thread - http://www.magiclantern.fm/forum/index.php?topic=7752.0
I observed strange pixels on the bottom of image.
No matter what resolution, white line is always there.
If anyone can help and explain why is that I would be grateful.
I use Pretec CF x567, Canon 7D, 50mm f/1,8II, macOSX

The build on that page is from back in august, I believe that version is out of date and had issues with vertical resolutions above 600, check to see if the problem shows up on very low resolutions if not you need to get a newer version, you can find a lot of them here.

Quick question- when not using FPS override we can assume frame rate is canon native? (i.e. 23.976 not exactly 24 when set to 24 in canon menu)

correct.

While that's true in normal mode I have read that in zoom modes it defaults to 30 FPS when not using FPS override, I have not tested the FPS override so can't be sure, maybe someone can confirm that.

I'm still a tiny bit confused about how resolution and crop mode affect the image... is resolution simply determining how much of the sensor area to use and zoom mode becomes only a crop?

i.e. if we stay in the same resolution as regular but do a 5x "zoom" (read: "crop"), is it the same quality but simply a smaller field of view and no aliasing?

Also, does crop mode affect depth-of-field (assuming same distance from subject)?

Thanks!

Resolution is simply the output size you want to record in.
The difference between normal and crop is not a resolution change but how information is read from the sensor, let's assume you want to record at 1080p we'll in normal record mode the camera uses the whole sensor but because the sensor is so much larger than 1920x1080 it has to throw away a lot of data in between lines, in crop mode however it uses the very center of the sensor at 1920x1080 resolution or what ever res you picked, while it's true that the sensor is being cropped in zoom modes you are actually getting a 1:1 ratio in pixels unlike in normal which is splitting up lines from the sensor to match the resolution you picked and can end up with some nasty moire aliasing.

If you are trying to frame the same shot in normal and zoom with the same lens it would require you to set the camera a lot father back in zoom mode which would affect your depth of field I would say.

This might sound like a crazy question but I have been thinking about this for a while, the 7D seems to be capable of some really great footage but seems to be held back a bit by it write speed to the card slot, what about the HDMI port?
Is it possible to output a clean uncompressed/RAW image out through the HDMI port, if so wouldn't we theoretically be able to record at the cameras max resolution and would also give people the option to record in any format they feel like with an external recorder.
Would be something the ProRes guys would probably love.

The Lexar 800x cards have Max. Read Speed: 120 MB/s and Max. Write Speed: 45 MB/s.
So don't expect too much from that card.
(The Lexar 1000x has 150/145 MB/s spec.)

Thanks very much Pelican, that explains a lot, I will be ordering a 1000x very soon I think. =)

I do not yet own a Lexar but if people on this board a correct it seems the 1000x cards are the way to go, the 800x for some reason even rated at 120mbs seem to have trouble reaching even half that speed. I would be interested to hear if anyone with a 800x has managed to hit 80mbs on their 7D?

Hi All

Long time lurker over the last couple of years. Thanks to all the devs for making this incredible hack - it truly is remarkable!

Don't know if this has been discussed or even possible, (and I have read a LOT of posts and didn't see anything), but are there any plans on creating a module that could write either ProRes or DNXHD to the CF card? I don't mind not having RAW controls and would love the option of having a 10-bit 4:2:2 Prores I could work with. Even maybe MJPEG (like the 1DC) would be good for me.

Cheers

This post is for discussion on 7D raw you would be better off asking that in the feature request section of the forum, that being said I wouldn't count on a module to do that, I couldn't imaging it would be fast to covert footage on the camera to prores ect why would you want to anyways, RAW is superior to ProRes and DNXHD except in file size. Once you taste the true power of RAW nothing else compares.

Edit: after reading the stickies in the feature request board again it seems asking for codec support on camera is not allowed, it seems MPEG might be possible but anything beyond that won't be on camera ever.

Just a warning to anyone buying cards on ebay, there are MANY fraudulent cards out there, with different stickers or even modified to say they have a higher capacity in windows than they really do. Always format the card and run a benchmark / test utility (Google it, there are many) to check that the card has the speeds and capacities claimed.

http://www.ebay.com/itm/GENUINE-Lexar-16GB-Professional-1000X-Compact-Flash-CF-150MB-s-UDMA7-VPG-20-HD-/270999842800?pt=AU_Electronics_Memory_Cards&hash=item3f18d96ff0

I can recommend this shop 1800 Memory on ebay, I have purchased 3 SanDisk card off them and all have been genuine, I plan to pick up a Lexar from them maybe soon, not sure if I prefer to get a Komputerbay because they are cheaper but I have heard they are unreliable so will probably go for a Lexar.

I made a short video to show the high write  speed of canon 7d.
To get the camera to wright at 90,4mb i lowered the fps to 3.

Am I missing something here, the camera even if it says it's writing at around 90mbs it's clearly not actually writing that much to the card when you are recording at 3fps.
The file size right before the speed indicator is a good example of this, it took you 11 seconds to write 92mb or raw footage.

@1% What exactly is that speed indicator, i was under the impression it was the actual write speed to the card, is it a theoretical max speed or something?
Shouldn't it be telling us in MBs how much is actually being written?

If your willing to record in 5x mode then you will never see moire or alias issues, I'm considering getting a filter soon to test the performance with 1x mode but I'm almost certain that it will just decrease but not completely remove it in 1x mode.

As for professional use I would ask what camera alternative at the same price range would you consider?
I don't know of any I would like to buy that can do what the cannon cameras can atm and not break an average consumers wallet, if you can afford a 5d3 then yes it will be a better option but its also a lot more expensive for what I consider minor improvements, I would only recommend people spend the extra if you have cash to throw around, the black magic is another but I personally hated the camera design even tho the image is reasonable.

Am I planning to use the 7D professionally? Yes indeed I will be, have I yet? No not yet due to some limitations that are mostly just due to the fact the firmware is in alpha and needs some love which I'm happy it has been getting a lot in the last month.

I have definitely seen Alias issues in 1x mode when recording things like fences, brick walls, dense shrubbery and certain types of clothing, color banding/moire ect not so much.
I have pretty much stuck to 5x recording because these issues are literally non existent when using it.
I don't have a VAF filter so I could not tell you if it works.

I find that the aliasing is worse in raw but you don't really see color banding like the image you posted above, I'm guessing to colors have a lot to do with the h.264 compression.

When scaling your footage to 1080p the aliasing is decreased but still apparent.

Quick Question.
My girlfriend is doing an outdoor static trapeze performance on friday and i would love to use raw to record it, the "professional" videographer used a old camera that did it 480i for her last performance and i was pretty pissed.

Its going to be about 4 and half minutes long. I have a 16gb sandisk Extreme card (not extreme pro). Even recording in 720p24 would be fine if 1080p24 would be a problem. Is any of this feasible at this point. Thanks for the noob help.

You should be able to get over 6 minutes of 720p on a 16gb, 1080p is not yet possible.
Be aware that this is still very much in alpha so it might not be the best idea to take footage of an event that can't be repeated as there always a chance something will fail with the build, I would recommend you try the latest build out and get used to it and decide for yourself if its stable enough for what you want to record, finding out on the day would suck.

I know that 7D is 1729x972 RAW. this is a sub hd output and I do not know if it useful for professional use.
but RAW have better detail than h264.do you believe that 1729x972 RAW upscaled to 1920 is better than a native 1920x(X valor) in h264 native? or the image is less sharper, blurred?

thx for help.

The 7D can already record at higher resolutions than that but if the question is about upscalling in general then yes even back when we were locked to 600 vertical res it was still a much cleaner less blurry and artifact free image when upscalling to 1080p compared to h264 compression, I would not go back to using h264 professionally after raw.

Most profesionals in the film industry wont touch a camera that doesnt support raw, the whole point of getting a camera with raw support is for professionals who need a lossless image to work with.

Is it just possible that no one has tried the FPS override till now with the latest builds?
The build that it was disabled in is from last year.

I agree with levisdavis, while the 128gb would be fine for 720p you won't get close to 1080p because of the write issues.

I also agree with his suggestion to buy multiple card but I will elaborate more, it's almost always better to buy a lot of smaller cards over one large card, the reasons being that it ends up being cheaper in most cases, if a card fails you have backups compared to not having any card if you only had one, while your transferring data of one card you can be recording with another which is really important if your doing many hours of filming which It sounds like you might be doing, the only time I could see it worth buying such a large card is if you have to do one long nonstop 30 minute shot.

As for cards that can do 1080p I've heard many conflicting reports on the matter, it really is impossible to tell just which cards are best until the FPS override has been implemented.
The best cards I've seen so far reported though are the Lexar 1000x cards managing to hit around 90mb/s but maybe someone who has one can back that up.

Put the mlv files and the mlv2dng in the same folder together, then drag and drop.

You don't actually have to have the MLV file in the same directory as mlv2dng, you can drag and drop it from anywhere and it will output the DNG files to the same directory that the MLV file is in.
I like to put each MLV in its own folder and then do this so that they are all nice and organized and I don't have to move multiple files.

Hi, I'm looking to buy a new card to shoot for a web series I'm working on.  I want to shoot RAW, but I also don't want to create massive file sizes.  It seems like maybe 720p would save me a lot of file space and probably wouldn't make much of a difference since I'm outputting to web.  How many minutes of 720p raw would a 64 gig card hold?  I assume RAW has a fixed data rate for each resolution, right?  If I can't get at least 30 minutes on a 64 GB card, it might not be worth it.  It looks like the 128 Komputerbay is a better bang for your buck.  Would the lower data rates of the 128 give me the ability to shoot 720p RAW?

Thanks to all the developers who are working on this and arrinkiiii for putting together the donation.  I hope my 20 bucks helps!  I'd be interested in continuing to find ways to empower the active community of 7d enthusiasts with ways to incentivize developers.

Even 720p RAW will take up a lot of room but not too bad, I'm taking a rough guess you would probably get at least 30 minutes onto a 64gb card at 720p, as for speed even on my 60mb/s SanDisk I can record resolutions above 720p, the 128 Komputerbay is rated higher than that I think so should be fine.

alsey7 what settings are you using, what type of lights are in that room, what ISO you set on ect ect.
The more info we have the better we can help you.

It looks like to me you are trying to take footage in a very dark room at a very high ISO with Dual ISO turned on and its causing a strange vertical pattern as a result.

Hi everybody,

I've been reading this thread for a while, can't tell how amazed I am with all the stuff going on,
now I feel ready to try and unleash the power of our beloved 7D.
One little question regarding external monitoring:
I read some posts saying that it would be ok to use external monitoring, but not being able to playback footage.
Than I read another post warning not to connect anything to the hdmi port.
Can someone help me with this? I really love my electronic viewfinder..

Greetings from Brazil,

Daniel

While the external monitor will work I found it to be incredibly unstable, the ML interface would not display correctly and I would get lockups doing things that would not lock up without the monitor, you should be safe trying it as different hardware may have different results just be prepared to reset your camera a lot.
I ended up just removing mine for now because it frustrated me too much.

FPS was the problem on 50D, you can only 30P the non zoomed size. If that is fixed here you should have 1080P.

That was the conclusion I jumped to also.

I'm sorry if I confused anyone earlier, as of right now 1080p is not available continuous but with the cameras specs it should be theoretically possible in the future when the 7D has had some tinkering and then ONLY with cards that can unlock the cameras true write speed.
Don't expect 1080p raw on your 60mb/s SanDisk as I know a lot of people here have them.

While the 50d does seem like a nice option the slower write speeds, smaller native res and lack of audio puts me off, the 6d as well lacks potential from what I've read due to the limited card speeds the slowest of the cameras you mentioned.
I'm assuming that continuous recording is what he wants, if its just short clips then it really would be a different situation.
Speaking of card speeds I could be wrong but isn't the 7D second to only the 5D III, it's the only other camera I think has the potential to do 1080p continuous If that is going to be important to you, although we still don't know if it possible yet.

I currently have a 60D which is pretty limited shooting RAW. Is it worth it to pick up a used 7D for 6-700 bucks for RAW now? Or should I wait til the builds are a little less volatile? I'm really on the verge of bartering some music equipment for a BMCC.

Before the live view was fixed and the vertical resolution was limited to 600 I would have told you to wait but with the latest build I would say yes go for it.
I had very little issue getting it to work, as long as you read carefully how to install it you will be fine.

I will point out some pros and cons as best I can to why you should or shouldn't get one.

PRO
Write speeds reported up to 90mb/s
Dual ISO 14 bit Recording, I can't stress how awesome this is.
Continuous Raw at Native Resolution 1728x972 with fast CF cards.
No moire or aliasing in crop mode.
7D is a very well build and we'll thought out camera in its layout and features.
Still in my opinion one of the best still cameras around if still pics matter to you also.

CON
Dual Processor means its hard to hack, ML builds are always behind other cameras.
No final build of ML, 7D is still very much in alpha.
No 1080p.... Yet crosses fingers.
Occasional pink frames in footage, easy to cut out to be honest.
A few bugs that cause lockup s, annoying but not the end of the world.
No FPS override in crop, yet.
Aliasing and moire in non crop mode is very noticeable when filming patterns.
External monitor support in this build is very broken, don't even plug one in till fixed.

Even though I have listed more cons they are minor issues and the pros really do in my opinion make this camera the second best for raw behind the 5D III, I would say if you could afford the 5D III get that as it's better supported but for cost the 7D is simply amazing for video since raw and dual iso was unlocked.

Its probably just something that needs some tweaking, I would settle for 1728 res in crop continuous but yes 1080p would be a dream come true.
