You can walk away, but I usually don't. I work on another PC nearby or on a laptop, keeping an eye on the capture.
VirtualDub will continue to capture until you run out of space. Meanwhile a lot of things could happen. You could have a power outage (in my geographic area, that's always a possibility).
Or the tape could break (Ouch! And
VirtualDub will just keep going).
Or something else unexpected. You never know.
The only filters that should be applied during capture are your proc amp level, brightness, etc. Never apply other filters during capture.
Another tip: When people first start capturing a bunch of tapes the temptation is to overdo it and rush the project. For example, capturing a full 6-hour tape is one path to a nervous breakdown, along with capturing a bunch of tapes wholesale and trying to fix them all at once. When you're first starting, do one thing at a time until you get a handle on what's happening. It won't take a long time.
