I have a bunch of QTs i created in After Effects using QT with Animation codec + alpha channel but when i bring those into Vegas 8 i get image on black screen. ANy reason for that?
You need to select the alpha channel. Right clip on the click and select PROPERTIES. Then select the MEDIA tab. About 2/3 down that page is an option for Alpha Channel. Select whichever type is in your source video (if you don't know, just use "straight (unmatted)."
