Question

CatDV is reporting an audio/video length mismatch (FCP)

Answer

If an import warning is displayed when you import movies captured with Final Cut Pro this often indicates that the file has dropped frames. You can check this by opening the movie in QuickTime Player and comparing the duration of the audio and video tracks. If the audio track is shorter you probably have dropped frames, even if FCP did not report this at the time of capture. The total movie duration will match what you expect based on timecode but the movie will "run out" of data before the end. As a result CatDV will have a very hard time correctly identifying scene positions because there is no consistent way to refer to frames within the movie. If at all possible you should recapture any affected files. (Note that you may also experience similar symptoms with other capture software).
