I honestly don't see how MLVFS is in any way better than MlRawviewer. I'm not trying to engage in a debate I just don't see how DNGs, JPEG previews, WAV files and what ever else MLVFS produces is any better than MlRawViewer. Now I see the point that MlRawViewer hasn't been updated since Dec 2014, but how much progression has the MLV format had since then aside from code optimization and menu adjustments. I haven't seen much. So yeah it was last updated in 2014 but MLV hasn't changed.... much since then. MlRawViewer allows you to playback real time mlv files on Windows, mac and Linux, it produces prores 444 and DNG if you want the additional workflow and it works right out of the box. No extra junk files to install.

MLVProducer is cool also as it has some color manipulation features and what not but that (to me) is contrary to my work flow. I say all that to say this. Each of these programs were released free and have their own quirks. It's not necessary to downplay one app because it wasn't updated in a few years if the technology it supports hasn't changed much since it's last update.

Thank you AWPStar. You're too kind!

MLV files are massive. I'm uploading a file now. I'll PM you when it's up.

Ok, so this is very, very impressive. There are a couple things I can't find, however. If someone can help me figure out how to queue multiple files for batch encoding, that would be awesome. I see the render queue but I don't know how to add files to the queue. Is it possible is these builds? Also I can't seem to export audio, although I know the mlv files have audio. Am I missing something? and I apologize if I don't sound grateful, because, I am very grateful!

I've had this same problem when using my Marshell monitor. To fix this issue I changed the HDMI out to force VGA output in the ML menu. I lost the HD output to my monitor but I was still able the use the monitor while recording flawless MLV files. Hope this helps: http://wiki.magiclantern.fm/userguide#force_hdmi-vga

Hey,

when exporting from mlrawviewer the program will get so far and then freeze and I have to manually quit the program. It's only just started doing this. Any ideas (other than "reinstalling" the program i.e unzipping and replacing because I've tried that) It does this about about 8 out of ten attempts. If I keep trying it I will eventually get an export after many failings of the same raw at varying export percentages.

I have the same issues. It seems to occur when I leave my laptop running and come back to it after a while of converting. The only thing that seems to resolve this issue for me is to come back to my laptop periodically and keep my hard drive spinning. Not sure if this will help you but it might.

Hi! I use A 5d mark III with ML for 1.1.3 firmware and a build from the 20th of may.
I recently switched to MlRawviewer 1.1.7 and exported som MLV files. When I exported I noticed these red artifacts in the yellow parts of the workers clothes.
Does anyone have clue why? Could it be a wrong setting? The red artifacts are not there if I look at DNGĀ“s.

This is similar to an issue I had. You can check out how I got around it here: https://vimeo.com/94709318 The trouble ticket is here: https://bitbucket.org/baldand/mlrawviewer/issue/66/overexposed-highlights-issue

Thank you Baldand. The Viewer is a very, very good tool.

Like my predecessor, I think a histogram and the whitebalance displayed in Kelvin would be a very good next step.
Without the color and exposure is always a little sloppy and sometimes off.
With exact control over these parameters a conversion to DNG would be obsolete in most productions
and you could go straight to editing with the log-gamma-applied-10 bit-almost-linear .movs.

That would be so great :)

Duplicate Questions / Re: 7d mlv resolution problem

hello
i've installed the latest nightly on my 7D and trying to capture some raw video.
when i try to use mlv in resolution greater then 1728 i get this:
1792 is not possible in current video mode (max 1728)
how can i get passed it and get to FHD or more?
where do i change the video mode?
thanks
You have to enable crop mode to get higher resolutions. What is crop mode? The button in the back of the camera you push to zoom in on your subject get accurate focus. When in crop mode go back to the ML menu and change the resolution. If you exit crop mode the resolution resets to 1792. TIP: disable 10x crop mode. I'm not sure which version of ML you're using, but 10x crop freezes the live view on mine. To unfreeze the camera you have to cycle through the Menu button (Canon Menu not ML Menu) or the preview button.

A few more things to consider. If you decide to get a 50D and 7D you will need to purchase batteries for the 50D as they are different from the 60D and 7D. You do have the option to get a power adapter that works on AC power http://www.amazon.com/Canon-ACK-E6AC-Adapter-Mark-Digital/dp/B001KBZ3PK. Also raw obviously produces large files. You're gonna need a lot of cards, some way to dump the cards between takes, and a ton of hard drive space. I easily filled a 1TB hard drive with the MLV files alone. Be mindful of the storage needs of raw when making your purchases.

Also, Audionut asked what is "LM Raw". He was referring to the misspelling of the abbreviated ML as in Magic Lantern, not Lantern Magic.

People have used the DNG files, RAWMagic, ProRes422HQ.... all kinds of things. And then of course a wide variety of color correcting & color grading software and editors. What's your favorite way to do it?

I prefer working with video files that I can play outside of the editor. So ProRes or Cineform are my preferred way of editing.

What exactly do you think I'm doing here, talking to peeps like you on the ML forums? LoL

There is a first time for everything. It's my first time with RAW.

Fair enough. I'll tell you the Magic Lantern raw workflow is not as straight forward as Black Magic's Cinema cameras workflow but the quality of the footage definitely holds up and is certainly worth it. I highly recommend you start testing the workflow now with your 60D to get a feel for what you'll be working with. In your spare time check out this video too: https://vimeo.com/70637970 (Magic Lantern - RAW - Workflow Tutorial). This workflow involves extracting the DNGs from the mlv/raw files. I'm not a huge fan of the DNG workflow but it's really up to the editor.

I have both the 60D and 7D and both are equipped with the Mosaic Engineers anti-aliasing filters you were talking about. I'll tell you that tracking focus does get a little harder when you use that filter. The minimum focusing distance changes because you're adding more glass in front of the sensor. It does however eliminate most of the aliasing problems.

Like I also mentioned if you're going to be shooting long takes, there is that possibility that you'll lose that take. You seem to already know that's possible, so no need to beat that dead horse again. I haven't shot 10 minutes straight yet but now I'm curious to see if it is reliable.

Well I look forward to giving it a try myself and seeing how it all works! Curious - why the need for an extra piece of software? Doesn't PremierePro natively support RAW files at this point?

Premiere supports DNG files yes. You will still need software to convert the mlv/raw files to DNG in order to use them. If you're going the DNG route, you will need extra software to extract the DNGs. If you're going for native mlv/raw into Premiere you will still need extra software to import mlv/raw to Premiere. Magic Lantern's raw files are not supported in Premiere without plugins. Either way you will need extra software. I don't want to come off as rude but if you didn't know that you really should dig a little deeper to fully understand what you're committing to.

Well if we don't know that exFat caused the problem or fat32, and exFat allows unlimited file lengths, I think it's the better option. Thoughts?

I don't see the point to using exfat. The files are split in camera but the camera will continue to recording until you stop it or the card fills up. When you open the MLV file it will playback all of the split files as if they were one large file. I use MLRawViewer to playback and encode my raw files. MLRawViewer allows you to convert MLV/RAW/DNG files to ProRes (on mac/windows) or you can just extract the DNG files to separate folders. 

I uploaded a video to Vimeo showing one of the issues with MLRawViewer here: https://vimeo.com/94709318. The issue I had was the highlights, for an intentionally over exposed shot, weren't encoded properly. The highlights simply made the clip unusable. Baldand, the developer for MLRawViewer, got a hold of the video and is working to fix that issue. The great thing about MLRawViewer is that it can batch encode all your raw files to ProRes, drastically reducing the file size and allowing you to edit. It does take some time to encode but you can think of it somewhat like dailies for you film nerds. It made 782GB of raw video to 230GB of ProRes video.

According to the chart, 5Dmk2 does not support exFat. Which means that lovely full HD raw is going to be limited to clips only a few seconds long unless I'm missing something...

It looks like nick.p beat me to it, but, you shouldn't have to worry about using exfat for the 7D. Once the file size reaches 4GB it creates a new file. I've shot about 4 and a half minutes of raw video without problems. The reason I cut it short is because of my card sizes. I only have (4) 64GB Transcend cards 1000x. I'd be weary of using exfat anyway. I've read in the forums that a guy had a clip that he was unable to open. I'm not sure if it was exfat or standard fat32 but the file, from what I understand was like 100GB.

You'll be dealing with glitchy external monitoring, no playback, and the constant fear of not really knowing if the footage you just captured is corrupted.

I'm not sure if you're talking about playback in camera or on the computer (mac/pc) but it is definitely possible to preview your clips on both the camera and computer. On your camera make sure you enable the mlv_play module and hit the play button to play the files back. It's not real time, it's raw for crying out loud, but at least you can check framing and what not. You can even delete takes you don't like. Quick menu button! As for playback on your computer, you can playback the mlv files just fine with the MLRawViewer. Check that out here. http://www.magiclantern.fm/forum/index.php?topic=9560.0

I have a Marshall monitor I've used twice with out issues shooting and monitoring raw. The "not knowing if the footage is corrupted or not" is somewhat true but it's the risk we're taking using nightly hacks.

Raw Video / Re: 7D and the SanDisk 160 Mb/s

Quote from: hog120 on May 13, 2014, 12:15:20 AM
I've noticed the warm up period you're describing as well.  It 'warms' up quickly though, and then it becomes a non-issue.   Your camera settings, as you mentioned, are important as well in terms of shooting RAW with ML.  What CF cards do you recommend that work better than the Sandisk extreme pro 160mb/s?

I have 4 Transcend 64GB 1000x cards. I wont say that they work better than another card because I haven't used any other cards. I do have 2 Transcend 32GB 400x cards that I used before I started using raw but they're slowly beginning to collect dust.

Raw Video / Re: 7D and the SanDisk 160 Mb/s

Quote from: hog120 on May 12, 2014, 09:31:31 PM
My guess is that if you're getting pink frames, you've maxed out your cameras CMOS/processing power/buffer for that particular resolution.  It's not the cards fault most likely.  On my 5D Mark III that same card will shoot 1920*1080 RAW with no pink frames.  If I push my Mark II too far in resolution, like 1920x1080, with that same card, I will get those pink frames

You may be on to something, but, like I mentioned before, I stopped getting those pink frames after a bought faster cards. Now their could be other factors to pink frames of a 160 Mb/s card such as global draw, photo resolution, proper buffer caching, etc. I've noticed that the camera or card, not sure which, has to warm up when shooting raw when I first turn the camera on for the day. Sometimes the first clip will time out after 8 seconds then the following shots are continuous.

Hi Aria,

I've been in and out of the forums daily checking up on the updates of the 7D raw functionality. I've even shared a little of my experiences specifically for the 7D. To be fair I've been using the Tragic Lantern builds but I expect the newer Magic Lantern builds are the same. You can check out the links below which might help you out without having to repeat myself or others. Hopefully these links help.

So based on your write speeds of your card you should not have any issues. Like a mentioned the 7D maxes out at 80mb/s so the only recommendation I have for you is to disable global draw and make sure you're pictures are set to small. I recall a time trying to shoot raw video and it would pause every 6 seconds or so. I checked everything and everything was good but I still couldn't get to to record continuous until I remembered to set the pictures to small.

I've run into a problem with the pink/magenta highlights in Premiere Pro CC. I've been using the MLRawViewer to convert the MLV files to ProRes MOV but there's this overexposed clip that is pretty much unusable when converted to ProRes. So I found a way around the highlight issue and the garbage encode in the highlights by using blending modes. Check out my workaround in the video below. I'm all ears for suggestions.

I have a 7D and I answered a similar question before, that is, if I understand the question. First I'd say identify both the read and write speeds or your cards. I use the Transcend 64GB 1000x cards and I rarely get issues. My 1000x cards max out at (160mb/s read) and (120mb/s write). If you take a look at the chart here: http://www.magiclantern.fm/forum/index.php?topic=6215.0 you'll notice that the 7D maxes out at 80mb/s. The reason I say identify both your read and write speeds is because you mentioned your card in a 64GB 90mb/s. Well what is it 90mb/s at? Read or Write? or is it both.

Also your picture size needs to be set to (jpeg Small). So don't have your camera set to take raw photo (cr2) files. I think it has something to do with the buffer size....

Those images are simply amazing! Have you heard of Mosaic Engineering's Variable Anti-Aliasing Filter (VAF)? It can help with the aliasing issues. I have one for my 60D and I just ordered on for moy 7D.
