Render .mov with alpha channel (unmatted, million color+, etc). To check the transparency I import it back into AE. Looks fine, then embed same .mov file into a web page. No matter what browser I use the alpha layer is not recognized (usually a black box). I'm using AE 6.5 (no tech support). I hope it's a mistake I'm making and not my old software.
You have alpha in the video. AE is not your problem. Your problem is the way you're playing it back. I don't know of any way of embedding a Quicktime video on a web page with alpha. The only way I know to get video with alpha on a web page is to use Flash.
You should be able to take your video into the Adobe Media Encoder and render it as a flash video. Now, how you go about doing the coding to place it on a web page, I don't know.
