Title: A question about video file types.
Post by: firestar12 on March 26, 2009, 23:02:02: Are there any video file types that can carry an alpha (transparent) channel?

You can make animated GIF files, witha transparent colour, of course. Not really video, though.

I wish they did have transparent video file types! Would make animating things a lot easier.

It depends upon what you actually want to do. If you want a standalone video that will show the ambient background wherever you place it, then Terry is right: GIF is about the onlyâ€”poorâ€”choice.

If, however, you want to make videos with animation over a background that is part of the video, then various video editors offer â€œgreen screenâ€ compositing of one track with a color designated as transparent over another track.
Pinnacle Studio offers this in some versions. Sony Vegas, which I use, is a better, more stable, choice. You can get into the business for less than $US 100. There may be less expensive programs to do it.

Regards,
Marty
