hallo,
i tried to play rgba video with alpha in gem.
IOhannes proposed PNGA video, so i got one using 'ffmpeg -i %4d.png
-vcodec png rgba_png.mov
you can find it here (13Mb): http://kubriel.servus.at/uploads/rgba_png.avi
i tested [pix_film] enabling alpha with [alpha] without succes,
background is not transparent.
i tested video in resolume with nice transparent background result.
Jakub
