Hey everybody,

little question…i have to quicktime movies here…one is the animation itself…the other is the alpha channel of that animation and want both of that in flash…

Now what i did was compositing those anims in after effects, then exporting as a series of tga’s (with alpha) then importing in flash…

the problem is that the swf explodes from around 600kB to 2.1 MB…now there must be a better way of doing this…Do flv’s support alpha, if yes, how???
