[Andy Lancaster] “Is there a way to capture an entire HDV tape in FCP”
If there are no actual timecode breaks in the tape, then yes you can capture a whole tape. In the capture window, check in the tabs. You will find an option for breaking the shots at camera stop/starts. Uncheck this box.
Please don’t ignore actual timecode breaks. They do occur on HDV a bit and a workflow that includes recapture will suffer if you ignore them. As you are AutoDucking to AVID, I would consider the likely hood of the need to recapture is high. I have used AD to go AVID to FCP and getting media across has been difficult with recapture needed.
