Something might sound silly.
I am a newbie to AE. Created a simple text animation in CS4 and rendered it as Targa seq with alpha.
But when I import it in Avid MC 4.0.3 over an existing video, it just covers the layers underneath.
Can't key out the black background in tagra...although there is no background in AE. The comp size in AE and Avid project setting is not exactly the same...could it be due to this?
Comp settings wouldn't effect the alpha channel, but as an Avid editor/AE guy, you will save yourself headaches if you set your AE settings to your final settings in Avid. Avid just isn't as flexible and when it resizes it will often cause some strange scaling issues and artifacting.
As to the Targa issue, when you render it, in the output module make sure your video output is set to RGB + Alpha and in the format options change the resolution to 32 bits/pixel. See if that doesn't solve the problem.
