[TriLUG] Video editing advice

[Cristóbal Palmer]

Hey Doug,

I don't have answers for you off the bat, but I thought I'd point you here:

 http://www.ibiblio.org/joey/videolinux/

You might find some useful info there. If you pester nicely, you might
even get a response from Joey to a question you post there. :)
