Awesome stuff Robin, I'll check out openmovieeditor and your ardour3
patches as soon as I can! I don't even know what zoom automation is so
I don't think I need it. :) Syncing with ardour would be great.
Hopefully I can make it all quick and easy, otherwise the singer
freaks out a bit.

All the current videos are done with 2 behringer omni mics and no post
processing. It would be nice if we could have more mics for when
tracks with a drummer, and electric tracks where I drown the singer
out a bit. Ardour3 or openmovieeditor look like the plan.

Thanks tons!
Loki
