I've been copying some tapes to my computer, and when I played back the capture, the file seemed to have fewer frames than my DVD copy (the playback wasn't as smooth in certain parts). So sure enough, I checked the amount of frames in both videos at the problem parts, and the DVD copy did have more frames, and the capture noticeably skipped around more when going frame by frame. Now, with my capture software, I said lock in the frame rate at 29.97 FPS (yes, it is an NTSC tape, NTSC-J to be precise.) I noticed though, during recording it would say 30 and 31 FPS instead of 29.97. Now, I assume the 30 is really 29.97, they're just rounding up, but might me forcing it to be 29.97 be what is causing this skipping? Might the tape really be playing back at 31 FPS? Thanks!
