Please let me know if the question belongs to somewhere else.
I have cs4 web premium which doesn't include aftereffects. I need to however make a green/blue backgrounded video transparent (alpha channel, if I got it right) to be used by flash/as3. I'm not sure if I can use either firework or illustrator do the job? another question is, for a short movie clip, which tool can be used to edit the movie frame to turn the non-green/blue clored backgroud into green (then adding alpha channel...).
I guess these links will help you
