Question:

If an imported video clip has a proper alpha channel, can Dogwaffle make use of it? Could I blend two video clips together?

I'm always on the lookout for inexpensive compositing solutions.

good question. Yes and no, or rather no and yes... Dogwaffle currently only has one alpha channel overall, not one per frame, so it doesn't get the alpha from the animation in your file quite yet, that is however planned for v4 perhaps as an option at a premium or simply in v4 TBD However, there is a way to composite two video streams. There are options in the Timeline editor to composite with bluescreen or greenscreen or similar. I haven't used them but essentially I know they're there to achieve some of the compositing tasks people do. Also, you can load a movie into the brush. That one can actually have alpha per frame. And animated brush can be loaded from an image sequence, so if you can save your AVI into a Targa image sequence you're in the config best liked by Dogwaffle. There are tools to further process animated brushes by applying filters to them similarly to the Timeline editor. It's called the brush timeline in the Brush>animated submenu Try it in the 3.1 demo or feel free to send me a short clip of a second or more with your alpha, I'll extract it into alpha-present targa files, or you can send me a sequence of images in BMP, Tiff or Targa. I think either of these I should be able to test with

I think I'll wait until v4, but thanks.
