I have a Canon DV camera and dozens of old tapes. Recently I've tried several of my recordings and all transfer to FCP without much trouble. I have two tapes that are a 1st generation dub from the master, which I do not possess. Watching these recordings on the camera's viewfinder, they seem to play fine. However, when I import either one into FCP 10.4.8 it is broken into extremely short pieces, which are too short to work with (several clips per second). I'd really like to digitize these, but I don't know how to get them into Final Cut. BTW I had the same problem when I tried iMovie.
