Export alpha channel as animation?

[Intbel]

Thanks for your response! Unfortunately, GIF transparency doesn't work well for smooth edges and shadows because it's binary. Read the section titled Binary Transparency: the Scourge of GIF in the link to see why GIF can't be used for professional looking compositing.

One of PNG's advantages over GIF is real alpha channel transparency. While Xara 3D outputs nice alpha transparency to PNG's, it doesn't do animated PNG's. Clearly it calculates alpha transparency, but I haven't found any way to get it out in an animated or video format.

Xara Xtreme exports animated gifs.
It will also export each separate frame, with a single mouse click, in transp. png with alpha channel.

I hope that is useful info.
