This looks cool. Something I have looked for on and off without create success would be a fully scriptable NLE

Something like this that would support simple fades, transitions, and maybe animation. The kind of stuff you can do fairly easily in a video editor, but with lots of fiddly clicks and zooming in and out of timelines.

I'd like to have a script that let me specify when different source media start, when to apply effects, etc. All written as a basic text file.

Anything obvious out there I've missed?
