So I have about a 5-6 min take, which covered several split MLV files. I rejoined them to a 20.39gb MLV file using the cat commands in terminal. When I try to convert this to DNG- only MlRawViewer will read the file- and then only partially- the first 1526 frames.
Based on where it fails, it looks like something got corrupted on the handoff from the first split file to the second. I tried rejoining the files just in case- still nothing. Is there anything I can do to recover the rest of the video? Is there anything I can do with M00, M01, M02 files?
Don't join the files. Just copy the files somewhere, run mlrawviewer and open first MLV file (you won't see anything about M00-Mxx). You will see mlrawviewer will handle all the files without additional help.
Same with MLVFS. You asked about 3 months ago:
