A sample of one of our DV Pre-Keyed Illuminated Dixie Fireballs! Shot with the lights on to include the smoke, and in 768x576 PNG Quicktime. Should work perfectly in Adobe After Effects and Premiere. Final Cut users, be sure the Alpha is set to Black. Please see the note about Codecs, below.
AN IMPORTANT NOTE ON CODECS
Apple appears to have stopped including the excellent, lossless, PNG video codec (which is needed for our pre-keyed footage) in the latest versions of Quicktime 10.x. But the codec is still available - you just need to download good ol' Quicktime 7 (it's free) and install that as well. Then reboot, so your software will have access to all the codecs. (You don't need to actually use Quicktime 7, you just need the codecs it supplies.)
If you are on Windows, go here:
and if you are on a Mac and only have Quicktime 10.x, go here:
Download and install the Quicktime 7 software, and reboot. You're ready to rock!
