Hi Graham,

Yes: set the alwaysbuffer of the player to true, then lay any masked image
over the player.

But what if the movie requires a different mask per frame? - imagine for example
a windmill going round, so that the sails are in a different position in each frame,
and you want the user to see the background behind the windmill except where
the sails happen to be. Then AFAIKS you have to have a kind of movie mask - is
this perhaps an alpha channel for the movie? I have tried to understand this in QT
Pro but have got precisely nowhere. Information about how to do this sort of thing
(including whether it's even possible) seems to me very hard to come by.
My current solution is to avoid the problem by replacing the windmill with a
spinning disk, but I would rather not.

i don't think this is possible at all :-(


Neither with RR nor with QuickTime...

In QT you can only have one static mask (starting with version 5, i think...)

Haven't tried to play such a movie in RR yet. Don't have one at hand...
(Anyone did it? Does it work?)

Try to use one ore more animated gifs.

I think this is the only chance to have "moving masks"
(a.k.a. "travelling matte" in serious video-editing business ;-)
in Revolution.

Hope that helps.
