Is there a recommended time limit for capturing video? Is it best to break it up? A dv tape can hold one hour of video - more at EP. Let's assume I have a very large hard drive with lots of space. This could apply to converting old VHS tapes as well.
No, there is no time limit. But from a workflow perspective it may be easier to use scene detection and the added advantage of scene detection is the reduced chance of out-of-sync errors. See my answer to your other question about Scenalyzer and HDVSplit.
>more at EP
At, of course, lower quality
