Corrupted files from CatDV?
I used CatDV Pro 8.1 a couple of years back to rip a bunch of videotapes to my PC. Life intervened, so I’m just now getting back to work on them. I have several hundred .MOV files that CatDV created (individual scenes from my DV tapes) but they all have some kind of problem wherein my editor(s) cannot determine the proper length of the clips (or on occasion, the frame rate). For example, I have a whole set of MOVs that my editor (Kdenlive under Linux) thinks are all 20 minutes 57 seconds in length. I can render them to an MP4, but the resulting duration is WAY off (hours, instead of minutes), making them impossible to navigate.
VLC will play them fine. If I concat them using QuickTime, the resultant file plays correctly, but again, the duration is way off.
Also, some other CatDV files play back at an incorrect frame rate in my editor, which also gives an incorrect duration. (For those files, QT reports the playback fps as 29.97, but the “movie fps” as 5.9.)
I tried using Premiere (on 2 different Windows boxes) and both crashed. I tried using VideoStudio Pro to combine them into a single DV file, which worked, but the resulting quality was terrible. It’s apparently transcoding them rather than copying, and doing a crappy job of it. AVIDemux loads the file, reports what I think to be the correct duration, but shows only a green screen.
Basically, it seems that CatDV recorded something wrong with the header or meta data in each file, which confuses my editors. Has anyone else encountered this? Any suggestions on fixing it, so I don’t have to re-rip four years of DV tapes?
