By importing entire episodes into the editing programming and them err, subclipping on the fly - i.e. scrubbing through source and marking in-and-out points within the wider episode, so you only insert onto the timeline the few seconds between your in and out points.

It's basically clipping on the fly, but it means I can start vidding immediately. The upside is that I often come across other stuff while I'm scrubbing through that I might not have considered otherwise. The downside is that sometimes I can't find shit for a while - it does help to do this with source you're fairly familiar with.

But clipping just...gives me ulcers. o.O
