I already know my way around nonlinear video editing on Linux.
I'd be interested to know what you use. I still don't use computers for editing my own work, because I've not found anything that works, or isn't painful, on Linux.
what do you think is the best "one, open digital format" (assuming it exists...) that would make it possible later editing and transcoding, with the smallest possible degradation?
I don't know if there's ever going to be "one." I would have thought for firewire caption of DV, the best choice would be a straight dump of what the camera gives you. That way, there's no transcoding, and whenever someone gets around to using the data, they can use it as-is, and render out with whatever's best at the time. And what's great as an editing source format this year, mayn't be next year, as editing applications change, and different CODECs become popular.
That's harder to think about for other analogue formats, that need to be captured, first. But one option has always been, at least when I've used other computer systems, was to play the analogue recording through a digital camera that has analogue inputs, too, and can work as your capture device (e.g. VHS into analogue in, DV out into PC's Firewire) for the signal to be passed through it (E-E, not re-record and replay).
