Light Lower Third

I purchased this and other lower thirds mov files, but everything has a black background. I want the background to be transparent. I used Adobe Media Encoder to export to an flv file. The I imported to CS4 Flash using the embed within timeline option. When I preview in flash or export, it still has a black screen. Hopefully ‘Darkroom’ can give clear instructions how to make the mov transparent. Only the mov file downloads, again with black backgrounds. Can ANYBODY help? Thanks!

Mac OS X Snow Leopard, Quicktime X, CS4 Master Suite

Are you sure they are rendered as transparent background? I tried using one of your lower thirds in a video and it all turns out black. I use Vegas pro 10

Thanks Man. Great Support

There are awesome, I just purchased them the other day.
