Flash MX doing animation with *.avi's file?

hello…

here’s the situation… i have an file1.avi, and i want to import it into flash mx, then do some animation in it, then export it back to *.avi format. can i manage to do so? will i encounter any problems? from the news i heard, some of the animation may not appear because of the *.avi’s format, is it true? hope someone could help me out here. and maybe suggest what’s the best software to make effects on a *.avi’s file.

:nerd:
