Title: Help needed my raw video has a green cast
Post by: tonij on October 16, 2017, 10:32:49 AM
Used a 7D (magiclantern-Nightly.2017Jun17.7D203) to record 100+gb of raw video+audio and out of all the clips one messed up.

DNG sample: http://s000.tinyupload.com/index.php?file_id=24362715427679068902 (http://s000.tinyupload.com/index.php?file_id=24362715427679068902)

I tried the line below without success, video remained green:

mlv_dump --black-fix=2048 -o output.MLV M14-0947.MLV

If I can salvage this clip that would be great, thanks!

Is it in 14 bit? If not, you will need to adapt that black level command

Also try opening in MLV App to see if it is recoverable, it has automatic black level fix, so if it is still green, it's probably not recoverable. It has saved many pink 5D2 clips for me.
