I’m having a similar problem. I’m capturing DV from a digibeta using Blackmagic drivers. The footage was originally at 23.976 but pulldown was added when it got laid off to tape. The tape has drop frame timecode.
In the log and capture window I set my In point at 01:00:00;00 and my Out point at 01:24:00;04. Then I captured the footage. After capture, I looked in the browser and my Out point had changed to 01:23:09;00 and I was missing the last 2 minutes of my footage. The workaround seems to be setting my Out point to be 2 minutes later than what I need.
I’m going to do some more troubleshooting. For now, the problem has replicated itself on two computers, both with FCP 6. I’ve never had any problems with nondrop frame tapes, so I’m guessing that timecode is the major factor. (For starters, when I go to the Batch capture window, it looks like FCP is computing the length of my clip using nondrop timecode, i.e. it’s showing up shorter than the length in the capture window.) I’ve checked Device Control and Capture settings but the only drop/nondrop option I can see is grayed out.
Has anyone else experienced this?
