Exporting a key?
Is there any way i can key some footage and then export the keyed footage so when i pull it up in another app i can place things behind the keyed image. I guess what im trying to ask, is how do i keep that transparency information saved in that video file.

You’ll need to render out your keyed footage to a format that supports an “alpha” channel. For example, if you render a Quicktime using the Animation codec and have it set for RGB +Alpha, millions + and “Straight (unmatted)” you’ll create a large Quicktime file that includes an alpha channel that can be recognized by editing software. Different software applications have different ways of dealing with footage containing an alpha channel…some times it recognizes it on its own, sometimes you have to tell it to look for an alpha.
