When capturing HDV from a Sony HDR-HC9, I've noticed that the scene detection is inaccurate: the break between clips always occurs 3 frames too late, so the end of each clip contains the first 3 frames from the following clip. In addition, the audio for those final 3 frames always is wiped out, and usually for 3-5 frames before that as well.
Up to now, this has been barely noticeable, except when I use one of the affected clips to start a video and so need to trim off those 3 frames, so I've just lived with it. However, I'm now experiencing longer audio dropouts in a few clips, with no audio for the last 15-30 seconds of the affected clip(s). The source tape is fine, and when I go back and capture the clip again, the audio shows up, but it's creating a lot of extra work for me since it's happening once or twice per tape.
I don't experience the same problem with DV capture (from a Sony DCR-TRV17 camera), which of course uses the external DV capture program. Scene detection is perfect, and there are no audio dropouts.
Is this unusual, or have others experienced it? Is there any way I can avoid this, aside from turning off scene detection? Also, could this be an IRQ problem? I notice that my IEEE 1394 card is sharing an IRQ with my video card. Not sure how to change this, or if I need to. Unfortunately, I don't seem to be able to control IRQ assignment in my BIOS. Any insights would be much appreciated!
