Tried it out! Nice error log. Easy to post to the forums. I'm trying to process a HUGE file. ~130GB

What I mean with the synced audio is just that the audio is exported and is easily imported into Davinci Resolve for editing.

NINJA-EDIT: is the code for MLVProducer open sourced? Is there some way to contribute?

Ninja-edit 2: ok, i saw in the post history that you've not provided the source

@AWPStar, yeah sorry. It's Deflated DNG, not Cinema DNG. Saw the options now!

Damn! It works. And the audio is synced, but not linked in Davinci Resolve. I can now record, dual iso, 1920x1080, 23.9~ fps.

Well i'll be damned. Where do I donate?

Hi,

I tried to convert .MLV -> DNG files with the latest intel build. The conversion works, and if I open the files in photoshop they look fine, but when I import them in Davinci Resolve the video looks like a TV that lost its signal. It's just a noise pattern.

The starting frame is up at 5000 something, and the ending frame is 5401 (the clip is 401 frames long). That might be the problem? If you want I can attach more info.

[Question for yall:]

Hi all,

thanks for your replies. @DeafEyeJedi I just generally just import the files into Davinci Resolve, edit the clips on the timeline (sound editing, cutting, arranging clips) and the move on to grading. For grading I choose a couple of hero shots, grade them to look as similar as possible. Then I grade the rest of the shots so that I have a suitable base grade for the whole project. After that it's easier to get creative with LUTs and whatnot

Lynda.com has a really good course on color grading with davinci resolve which I can recommend to anyone wanting to use resolve in their projects.

I've been using my setup for one larger project now and it works fine. It was a pain to set up but that's usually the case with anything video-related. RAWMagic helps quite a lot by giving you dng+wav already linked for use in resolve.

I've read your suggestions. MLVFS doesn't seem to do dual iso in windows. Even so it seems to be slow if you want to color grade using the MLV-containers if the material is dual iso. Also, I just think for compatibility it's easier to use some kind of standard format (DNGs) that can be shipped to other editors, or saved off and used later on a computer without ML-conversion support. Forward compatible material is critical for me. What I could do - I suppose - is to use MLVFS, export the DNGs and use them that way. Havn't tried that yet.

I tried mlv_dump.exe for windows and it was wicked fast. That's something to consider for me. It outputs all the DNGs + the wav file. The sound and image files are not linked however, which is a bit of a nuisance. What I gather from reading the forums is that it's some kind of exif/file metadata problem and should be fixable. But I don't know how just yet. Any clues?

I think MLVProducer is the strongest contender for Windows. Yes, it lacks support to export .DNG, but if that is fixed it will be a really neat program. Previews, point-and-click interface, and ease of use.

I was playing with the thought about doing some programming on some of the projects, but sadly everything else takes time in my life hehe. It would be neat to have a webpage where you can upload your material, the server edits and converts to your needs and then you can download a .zip. But with projects spanning TB+ that's not really feasible either. 

I agree that the biggest issue right now is the compatibility between OS:es. Right now I've got a OS zoo with OSX, Windows, and Linux running just to try out different programs with magic lantern. Nothing is quite on spot yet, but I guess the the same can be said about different video and image editing programs.

Question for yall:
I've been browsing the forums. With a 1200x card that works properly (~100mb write, ~120mb read) is it possible to do 1920x1080 in 3X crop mode? It works if I enable FPS-override, but sadly that removes the sound, which I need. That way I could do dual iso with sound and that would just turn my camera into a beast! Right now I get fram skipping around 20 sec in, and I can squeese a bit more if I use the LiveView hack.

I've tried:
Lowering the resolution 1600x900 (works but no HD)
FPS-override (works but no sound)
fiddling with the buffer settings ( Buffer fill method, and CF-only buffers - can't see any difference).
Preview options -> hacked no preview (get's a bit more recording time, but skips a frame in about 30-40 sec).

For anyone interested this guide was great for getting good sound with the 5D!

I use the MixPre-D, some cables to wire up the sound, and sennheiser microphones. It's really sweet sounding.

@danne

thanks for pointing me in the right direction. I found this video to be quite informative for those stumbling on the thread and don't understand what 3x crop means:

Would you all be interested in a sample video if I would shoot?

[Modules in ML:]

@Danne

If I've got "creeping" in the image what am I doing wrong? Don't know what it's called but it's as if there are loads of pixels in the image that are moving / changing exposure fast. 

Firmware: 1.2.3
Canon 5D Mark iii

Modules in ML:
Raw Video (mlv) 1920x1080
Dual iso 100 / 800

Video settings in camera:
Manual mode 
Shutter 1/50
(AWB or set WB gives the same result)
FPS: 23.976

Workflow:
Record -> transfer through kingston 3.0 usb card reader -> OSX.
Edit with your program cr2hdr-r (put MLVs in folder and run the program, yields folders with dngs and a wav)
DNGs are first created, and then re-created (for the dual iso conversion I assume).

When I edit these files in Davinci Resolve 11 the creeping is present. If I record under same circumstances but with standard RAW (not dual iso) then there is no creeping in the image.

What gives?

[My equipment:]

Hi all,

ML is a great tool and has a great community! I've been researching on how to use my equipment to get high quality video with audio into DaVinci Resolve for editing. I just got everything to work after a couple of days work and just wanted to share my experience.

I'm a journalist with some aspirations to shoot documentary... and wanted a run and gun camera that's rugged and can be used demanding situations, but at the same time deliver high quality files for editing. I'll post the finished list of things that I use to get the .MLV files converted and into DaVinci Resolve 11 for editing, then I'll post some thoughts from my research:

My equipment:
Camera: Canon 5D Mark III
Firmware: 1.2.3
ML version: 1.2.3 (Built on: 2015-04-28 02:13:03 +0200)
Computers: ASUS ROG 751 -> 16GB RAM, Windows 8.1, NVIDIA 980M GTX.
and Macbook Air (mid 2014)
CF card: Komputerbay 256gb CF formatted in exFAT
Lens: Canon USM ii 70 - 200mm zoom lens
USB 3.0 Media Reader — FCR-HS3 (transfer from CF to computer): http://www.kingston.com/en/support/technical/products?model=fcr-hs3


Programs in post production:
Converting .MLV to DNG: RAWMagic (NOTE: only compatible with OSX!)
Editing: Resolve Lite 11

Camera settings:
RAW video (MLV) 1920x1080
Aspect ratio 16:9
Files > 4GB (exFAT)
MLV Sound: ON
Movie Tweaks: Movie logging: ON, Dim rec led: ON
FPS: 23.976

Modules activated in camera:
file_man OK
mlv_play OK
mlv_rec OK
mlv_snd OK

Workflow:
I have two cards in the canon. One SD with the Magic Lantern install, and CF cards that i can record to. I leave the SD card in the camera at all times, and just switch CF cards. I use the Kingston USB CF card reader to transfer the .MLV files that are created in the camera to my Macbook Air computer.

From there, insert the MLV:s into RAWMagic, convert them with default settings. Move the converted files unto an external hard drive, and move them from there to my ASUS ROG main computer.

These files are now ready to be used in DaVinci Resolve.

Problems:
The biggest issue was for me to convert the .MLV files to DNG that DaVinci Resolve could read. I have read a ton of reviews, and blogposts etc to get this working in Windows to no avail. I'll post the research and comments so that others can read and comment to maybe save some time. There might be tweaks and other workflows possible that I do not know about but none that I've found. If you know of something else please comment.

These programs did not work for me:
Raw2cdng 1.7.4:
http://www.phreekz.de/wordpress/2014/04/magiclantern-raw2cdng-1-5-0/
After conversion the clip is broken up in 1 audiofile and several smaller clips in resolve. It's possible to connect them on the timeline and then try to sync the audio via "Auto-sync audio based on timecode" but it's not working all the time.

Raw2cdng 1.6.5:
This one delivers one file complete with audio in DaVinci Resolve but the playback is broken. When previewing the clips, they won't play. If put on the timeline in DaVinci Resolve I can play them and edit them. But the playback does not work. One workflow is to put them on timeline, then export them in some high quality format, and then edit that file again. But that's too much work for me to get non-RAW files working.

MlRawViewer (discontinued)
https://bitbucket.org/baldand/mlrawviewer/downloads/
Does a good job for previews of the .MLV:s! If you want to preview you workflow and watch the quality of the photos you've taken I recommend this software. Can also export high quality mov or DNG. However, it was not possible for me to edit the DNG:s in resolve. The .MOV files works, however.

MLV Mystic
http://secondsparkproductions.com/index.php/blog/8-mlv-mystic-mlv-raw-to-dng-batch-converter
The most promising program. Discontinued as far as I can tell, though. Will deliver two files in DaVinci Resolve, one for the audio and one for the movie. Just add the movie to the timeline and then add the audio to that and link them.

Program I settled with for the conversion:
RAWMagic
https://itunes.apple.com/us/app/rawmagic/id856514119?mt=12
Not open source and I don't want to endorse this in any way, since I know that the administrators in the forum really just want programs that are open source. The workflow is kind of funky since you'll need OSX to be able to convert. But this is what worked for me - just drag and drop MLV, convert with default settings and import into DaVinci Resolve. Yes, you need a mac for this, but I didn't find another way of doing just what I wanted. Just writing what worked for me.

Thoughts:
Since I wanted audio embedded with the .RAW footage it was not an option for me to record in just .RAW (I used .MLV format) and I also put value in having as neat workflow as possible and not converting between all kinds of programs just to get going with the editing. If you don't have mac and have some other ideas of what's working then do tell. I'd rather not have to do that step as well, and just have everything on my ASOS ROG workstation.

But in the end: Now I can record high quality footage on my Canon 5d Mark iii, and edit it in DaVinci Resolve. The camera is super comfortable to run and gun with, and with the magic lantern hack it's fricking awesome image quality.

I love the work that everyone does in the community, and this is not a shitpost to trash talk anyone in any way. I know that the open source contributors are doing a great work, and I've had really good times trying all of their programs. They are doing an amazing job, and I do hope that more people donate and contribute to the ML community so that they can continue their work of refining the software for recording and conversion and editing.

And I hope that this post can help some others along the way to getting their workflow going.
