Thanks a lot! I forgot the RGB + Alpha setting, knew it was something simple.

Under 'Video Output' of that same dialogue, I changed the Channels to be 'RGB + Alpha' In my test, everything that was the background (white), was rendered as transparent. Of course, I haven't tried doing any keying.... but I am pretty sure masking would work.... Try doing a simple test with your file, like one frame with no keying...that may be causing a problem, but I would imagine that it SHOULD work.. ~Mathew ----- Original Message ----- From: "Jeremy" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Saturday, February 01, 2003 12:58 AM Subject: RE: <lingo-l> Movie transparency > Can you point me towards how to get the transparent background from > AFX 5.5.
