Raw Video Postprocessing / Re: MLVFS - a FUSE based, "on the fly" MLV to CDNG converter

Thanks Pablo, but that's not what I was asking. MLVFS cannot do dark frame averaging and subtraction and I'd like to know if there's a GUI frontend for Windows that can accomplish that.

I'd like to quickly and efficiently be able to do this for some high ISO shots before bringing them into ACR. But I'm on a PC.

Are there any GUI based software applications that can perform a dark frame subtraction on Windows? I know that mlv_dump can do it, but I can't figure out how to use it. Even if I could, I get the feeling that it involves a lot of typing and moving files around manually and that there would be a certain amount of referring to a GUI based program to identify the correct ISO, etc. etc.

And I know that MLVProducer can do it as well, but the DNGs it exports are no different with or without the subtraction - it only seems to work when exporting to other formats and I want to stick with ACR and Cinelog. So are there any GUIs that can do dark frame averaging and subtraction?

You need to bring them through After Effects instead. Premiere does not rely on ACR.

Just edit the first image and the rest will have the same corre tion applied once imported to AE. No need to copy settings to all. Search the forum for AE batch import script. This will automate the process, creating sequences of DNGs with WAVs.

Modules Development / Re: Magic Lantern (RAW) Video format v2.0 (mlv_rec.mo)

I've been shooting some test footage using mlv_rec on a Canon Mk3 113 firmware. The build I am running is the 07/03/2014. I've noticed a problem with the MLV files and I couldn't find anyone else in the forum that seemed to be experiencing similar issues.

When I change a camera setting during recording (ISO or aperture) it seems to create a problem when it comes to converting to DNG using all of the current MLV conversion tools on both mac and windows. It kind of 'trips up' the converting program and causes it to stop making DNG's from the rest of the MLV at the point that the ISO or aperture adjustments were made.

Using MlRawViewer on mac I was able to skip past the point in the clip where the camera settings changed, but extracting a full usable take is not possible. If I do not adjust any camera settings during recording I can shoot any length of clip my card allows and convert to DNG with no problems. I have tested many times and it is definitely the change in camera settings that causes this. Does anyone else have this problem?

I can confirm this issue. I thought I was going crazy! If you change the shutter speed, ISO or WB during mlv recording then the resulting file will be corrupt. You can test for this by playing back in camera where playback freezes on the frame where the settings were changed, giving the message:

frame and block size mismatch: 0x375F00 0x23A9AB 0x376EB4
(for example)

None of the conversion applications can convert these files. Here's an error message from MLVBrowseSharp:



I did notice that this issue doesn't exist in the Feb 23rd build, but does appear from Feb 24th onwards. Hope that is helpful. Keep up the good work!

I am having identical problems to you with my 5D2, except I never shot RAW on my camera. Did you ever find a solution?
