Camera-specific Development / Re: Canon 50D

I've got quite a lot of ML video from my 50D, recorded at 23.976fps. Its metadata reports it is 30fps (as noted elsewhere).
If I put it into my NLE (Lightworks) and slow it down to 80% normal speed, the NLE does this by inserting extra (copy) frames once in a while, which is a bit clunky. If I use FFMPEG to re-label it as 24fps (near enough!), it only seems to be able to do this by re-encoding, which given that these are lossy codecs is, again, a bit clunky - not to mention time consuming.
Has anyone figured out how to just change the appropriate metadata in the ML output so it is correctly labelled as 23.976fps? This mis-labelling by ML is proving to be a very irritating bug!

In premiere you can 'interpret' the footage to be whatever framerate you want.

If you convert your ML raw files with one of the available free softwares you could also convert it to a DNG sequence and import it that way. In After Effects you can select a default fps for importing image sequences for example.

Alternatively you could convert it to a prores file with MLRawViewer prior to importing in your NLE.

I have a Canon Rebel xSi and am looking to upgrade to a camera that can run Magic Lantern and record RAW video. Ideally, I would like to upgrade to a camera which can record at least 1920x1080 RAW video at 24 fps. The frame rate does not need to be higher than 24 FPS, but it's OK if the resolution is greater than 1920x1080.

I've been researching Magic Lantern and its compatible cameras for a few weeks and haven't been able to nail down exactly which cameras are capable of this. The best that I could find is this spreadsheet, which is presumably out of date.

My first question is, which cameras with Magic Lantern can record 1920x1080 (or higher) RAW video at 24 fps?

As of right now, I've only been able to confirm that the 5D Mark III that can record at that resolution/frame rate. On eBay, I see a huge price difference between a used 5D Mark III and the other ML-compatible cameras. The difference is so great that I may consider getting a camera that has almost a 1920x1080 resolution but can run at 24 FPS. So my second question is, if you were to pick a non-5D Mark III camera that is as close to my desired specs as possible, which one would you pick, and why?

That spreadsheet is a bit out of date, but does present what is fairly stable in terms of raw video. What is not shown on this spreadsheet are the more new/bleeding edge features such as lossless compression,lower bit depth, 3k/4k and other smaller tweaks and improvements for various cams.

The cheapest Cam that does decent full sensor width at 24fps without the experimental tweaks is the 50D, which is what I have(in crop mode it can do 1080p). If you want to spend just a little more, get a 7D if you want more resolution and audio. If you don't need continuous recording or are fine with experimental lossless compression you could go for a 6D for a little more money, this bumps you up to a full frame sensor. Next up would be the 5D mark II. This currently probably the number 2 cam in terms of features and stability for ML behind the mk3, but that could change anytime depending on various factors.

Do you think that 5D3's full-frame sensor and low-light capabilities, along with recording at 14-bit, put the 5D3 at an advantage over P4K, at least in the realm of strictly 1080p video quality?

Yes, the 5D3's sensor is larger. With a speedbooster you can get close(around 1.2 crop factor with an xl speedbooster I believe), but not full-frame. The low light is something I cannot objectively compare, as I cannot find reliable data on it and I don't have both to compare, but the BMPCC4K is pretty darn good in low-light with it's dual ISO. In terms of bit depth, yes I guess the 14-bit has an advantage as well, but this is much more theoretical than practical. You really need to be pushing your image in post a lot before you'll see differences... Remember, with normal shots and grading people are having issues seeing the difference between 8-bit and anything higher. When comparing 1080p video, keep in mind also that on the p4k it will downsample from 4k to deliver a much sharper 1080p, bypassing or 'fixing' some of the issues a bayer sensor gives you.

I just want to post that the disadvantages listed on this post  are the opposite from my experience and these are actually the advantages of the 5d3 with ml
Also another huge advantage is that you have a world class still camera

But the choice is up to the individual and their needs

While I fully agree on the stills camera bit, I do want to challenge you on the disadvantages you think are advantages, let's go over them:
- 5D3 is raw video: Okay, this is clearly also an advantage, but the p4k also has raw if you want to use it. The disadvantage is that the 5D3 only has raw video and quite compressed h264(only at 1080p if I'm not mistaken). The p4k has a range of options in between, depending on your needs for that shoot, and they're all just as reliable.
- While I cannot comment on the 5D3 ML reliability, it is my experience with my 50D with ML that you sometimes run into issues. Nothing that a battery pull or reboot won't fix, but it is there nonetheless. This is not the case with the p4k.
- Workflow: Sometimes, when you need quick turn-around time, having a light prores file(with optional baked in LUT) is nicer than having raw files.
- Codec capabilities: Again, p4k can do many flavors of prores, as well as avid, as well as raw compressed and uncompressed, and BM Raw in the future. 5D3 only has h264 and RAW.
- Resolutions: If I'm not mistaken, the 5D3 cannot go full cinema 4k at 24fps (with liveview), and the 4k resolutions are only in crop_rec mode, not full sensor. The p4k can do 4k60 and with a speedbooster will have a larger 'effective' sensor.
- Framerates: The p4k can do 60p and 120p. The 5D3 will, unfortunately, probably never be able to go over 60p.
- Connectivity: The p4k has xlr, external power and USB-C for charging and data storage, things the 5D3 will never have.
- Onboard audio: I would argue the onboard stereo mics of the p4k are better, but that's maybe subjective.
- The (touch) user interface is exceptionally nice to use and fast, and has all sorts of nice features.

Another thing I'd like to mention is this: Thanks to ML the 5d3 has a lot of really cool features, but you cannot use all of them at the same time: You cannot get the highest 4k resolutions with audio and nice liveview and nice on-screen tools like zebra's etc.

I love what ML has done to boost these cameras in features, and I don't want to start a fight, but we should not be blind to the fact that they are not as complete or as stable as a product that was designed for (raw) video from the start, nor should we hide the facts from new users who might be deciding a purchase over this. But I'd love to know what you think.

Innocent question here: Are there any other ways in which the BMPCC4K is superior in video quality to 5D3 w/ Magic Lantern?

Apart from the differences in dynamic range, the 5D3 has a full-frame sensor, better low-light capabilities (maybe?), can record in 14-bit lossless, can also achieve 4K through crop_rec, as well as achieve dual ISO through the

Software reliability aside, I too have been debating with myself on whether or not to invest my money in a 5D3 as opposed to a BMPCC4K from a purely video quality standpoint.

I own a bmpcc4k and still own my 50D with ML. Have not used ML on a 5D3. The only way my 50D(and probably the 5D3) is better is the ability to take higher resolution pictures than 8 MegaPixels and maybe the colors(mainly skintones) a bit, the quality and strength of the physical body, and the ability to tinker. Other than that the pocket is better or nearly equal in every way imho. You can get larger than aps-c look with a cheap speedbooster knock-off and close-ish to full frame with a with an XL speedbooster.

It's not just about the specs and capabilities, it's about the workflow and reliability. If you do video and want a very good camera that just works for a lot of scenario's, the pocket is great. You can use it casually with a kit lens, onboard audio, with a baked in and good looking video LUT to lower bitrate prores footage on sd cards that can be edited on a laptop, which is what I did on holiday just now. The disadvantage the 5D3 has here is the raw conversion workflow, reliability is less of an issue.

But you can easily build up the pocket and use it in a pro environment, both for cinema as for studio or event coverage, knowing it will perform and will not let you down. The disadvantage with the 5D3 is the reliability, workflow, codec capabilities, resolutions, framerates, connection options, onboard audio, interface options...

If you like the tinkering and the alpha and the bleeding edge, ML is awesome. If you want to just go and shoot and stop worrying, grab a Pocket. It's crazy how much peace of mind it has given me.

As mentioned above, benchmark the card, also try disabling on screen items such as histogram, peaking, zebra's, or better yet, disable global draw entirely. The right card matters, check the forums for suggestions.

Not sure as to the rules of the forum, but most people here probably won't be able to help you in French. As to the image you posted: I don't see any black borders, where are you seeing this? Also, as far as I know you should not use both Raw and MLV, choose only one. BTW :the resolution you posted is low and is also not 16:9.
No, no adapter is fast enough.

EDIT: Okay, so I decided to try and reformat the card and now it works fine. I apologize if this is a common fix that I wasn't aware of. But when this started to occur, the card (lexar 64gb 1066 card) was only about half full. Will this happen every time the card fills up, or was there just some kind of glitch that was fixed when I reformatted the card? Also, if I remember correctly, the problem occurred after I received a funky file that was pink and digitized... Could that have been the cause?
Might be that the card was not able to record fast enough before formatting. Formatting or erasing a card that's been used for a while can really help.

I have been reading through this thread looking for the best settings that the 50D can achieve. I currently have a 70D but the RAW recording is sort of limited (SD card write) as well as the occasional overheating/ERR70 messages.

I am now looking at picking up a secondhand 50D just for video.

What is the best resolution/FPS that can be achieved for RAW video? and how long would this record for? Taking into account any overheating?

Will any CF card rated 120mb/s be OK for this or tare there specific brands only?

Some of the RAW video tests I've seen posted look amazing.

See: for current capabilities. Can confirm those numbers with a good card. Best to buy a known good card, ratings don't mean much. If it needs to be cheap I've had good luck with 32gb 1000x KomputerBay cards.

Not aware of this issue, then again, using a much much older build. Will try to reproduce and report back.

1 & 2 / First of all, I have to reccomend you to use the latest nightlies. I had more stable recordings by sticking to the latest nightlies.
Thanks, good to know, do you have a specific nightly build you're comfortable with?

Quote from: justinbacle on April 18, 2017, 11:44:40 AM
When I had this problem (happened to me several times) I found out that the "big" corrupted files were in fact recording that stopped at the beggining that I had to stop by removing the battery. These files are actually almost empty but are reported with a wrong size on the CF card. May be wrong, but that is what I think.

Well, I have those types of corrupt files too sometimes, but this looks like a different kind of corrution. The camera never indicates a problem or crashes, can review shot using MLV_play but cannot copy to computer(see details above).

Quote from: justinbacle on April 18, 2017, 11:44:40 AM
3/ I use MLV_Rec more because the interface is more usable IMO. The latest MLV Lite is mor usable though. I'd reccomend both other the old raw_rec as MLV files are much easier to handle ;)
I'll try MLV, thanks!

I've been using an old nightly build for quite a while without major issues. Also recently picked up a new card(KB 128GB 1066x). On a recent shoot with a lot of long takes I've had a couple of seemingly corrupted files(besides the occasional skipped frame). That is to say: seemingly records fine, can preview in camera but when copying to a computer it won't let me(on mac the card is not recognised until the problematic clips have been deleted, on windows the specific file fails to copy while copying and card is ejected). Also tried dd entire card under linux with similar results. This seems to happen more on the new card than my older 32GB cards.
My questions are:
1) Has anyone noticed something similar and on what build was this? Did you manage to resolve this in any way? What can I do/provide to get to the bottom of this?
2) Is anyone shooting on a newer build for a while you are happy with(and you consider solid)?
3) Do you find mlv_rec(or another setting) to be more stable/less skipped frames?

Build: Nightly.2015.Nov15.50D109
Settings: Expo. override: on, GD: on, zebras, peaking, waveform, fps override: 23.976, RAW full sensor 16:9 max resolution using raw_rec

I'm assuming a goal would be compression on 10bit if it's possible.

A1ex said (in that thread I think) that that does not yet yield interesting results, but who knows in the future..
Quote from: ItsMeLenny on April 13, 2017, 10:53:57 AM
also not sure what the two in two out discussion is
Two in two out is the method that does the lossless compression for compressed raw, see first post in that thread.
I too would be very interested in a build for my camera. I foolishly tried to build for the 50D in the compressed raw branch but the mlvlite module crashes the camera. I guess some work needs to be done for other (Digic IV) camera's?

I have no idea what you are linking to.

It's not free, but it's good.
Doesn't that already exist in the form of the DSLR controller app? I think this has the functionality you're looking for. I use it for monitoring video on the 550d and it works fine with magic lantern as well.

That's some great work! And yeah, I get the frame skip issue on my 7D too when my cards are about full. If I may, how do you manage that (or do you just not use those clips)?
Thanks! Indeed, just don't use them... Unfortunately...

Everything over the default settings sometimes stops recording after a while. The card warmup feature in ML does help though.

March 20, 2016, 03:32:25 PM

Had to some video for one of the girls in the video for a graduation type project of hers, made a montage of some of the footage set the the song they were dancing to. Shot on 50D with RAW full sensor at 16:9 max res. and at 29.97fps, slowed down in post to 23,976fps. Edited and color in premiere pro. Lenses used: Sigma 30mm f1.4 and Helios 44-2 58mm f2(those flares!  ;D). Used KB 32GB cards(1000x&1066x). Sometimes skipped frames, especially when the card was closer to full. If you have any questions regarding RAW on 50D feel free to ask.
Raw Video / Re: To RAW or not to RAW?
March 20, 2016, 03:16:18 PM
It depends is the only true answer really... Yes you can get vastly superior end results using raw over H264 but like any tool, it requires practice and experience. And besides that, RAW has a couple downsides you have to take into consideration. If you can get comfortable with the production and post of ML RAW beforehand, sure go ahead. But if you don't feel 100% comfortable AND have a lot of crew and money depending on it...

Currently using a 128GB Komputerbay 600x class 10 card. No issues at all with the size of the card, speed can be an issue though when I crank up the bitrate. When choosing a card don't look at class alone. Benchmarks is the only way to make sure a card can write fast enough.
Very interesting, thanks very much! Even with my poor coding skills this shouldn't be an issue I suspect.
Just a quick question I can't seem to find the answer to. Is it possible to use this feature and or the (raw) video recording features on a camera with a broken/worn out shutter? I ask since in the first post there is mention of err20. Thanks!
