  • Exporting alpha channels from flash for Vegas?

    Posted by Tevya Washburn on July 23, 2007 at 6:28 pm

    I need to export a Flash animation as video with an alpha channel for importing into Vegas. I’m not sure if I’m missing something, but when I export a Quicktime file, it allows me to check a box that says “Ignore stage color (generate alpha channel)” which I assume just makes everything transparent in place of the stage. But when I put it in Vegas, it has a black background where I want it transparent, but doesn’t show through the lower layers.

    I’m not sure if Vegas just isn’t recognizing the alpha channel, or if I need to change a setting in Vegas? I tried setting the lower layer as a child, as well as changing the compositing mode, but none of that seems to work.

    Don’t know what the difference is, but when I rendered with the same settings except no compression instead of DV/DVCPro compression, it worked perfectly. Sorry to start a needless thread. But maybe someone else has/will have the same problem.

    After adding the clip in Vegas, right-click it, choose “Properties”, and change the alpha setting to whatever you want. Does it work then?

    Yeah, I had to do that too. Thanks.
