Hi all, I'm new... (and perhaps not a native english!)

I have a RGBA avi with alpha channel but my NLE won't support this format.
I was seeking for a converter, to make a (so called?) masks sequence AVI file (taken by alpha channel, of course).

If there's a free of charge software is better but no essential.

My NLE is Video Deluxe 2008 PLUS (in U.S. Movie Edit Pro Plus)

TIA
