How to Render AVI file with an alpha?

[Roland R. kahlenberg]

Best to use the Make Movie function as you’ll have more output options available.

Once you’re in the Output Module dialog, choose Video for Windows and then for Format Options select No Compression as your CODEC.

In the Output Module Settings dialog, ensure that you select RGB+Alpha in the Channels dropdown menu.

Thanks for replying so quickly
I don’t see an option for rendering video for Windows. I have studio bundles of
AE7 and CS3 on a Mac.

Hi Steven
Unfortunately, I’m not on a Mac. Can you check if Flip4Mac has a free Video for Windows output download? Otherwise, it’s a paid applet.

You will also want to see if rendering to sequenced files does the trick for you.

Render as a 24bit targa sequence with rgb+alpha enabled…..the Duet user will then import and convert the seq to avi format.

Thanks a million,

Thanks guys!
I have access to AE on a PC in my office. I rendered out an AVI.
I’ll will also render as a 24bit targa sequence with rgb+alpha enabled.
This way will be better since I alway have my mac with me.

Thanks again.

Oh, When I Render as a 24bit targa sequence with rgb+alpha, Should it be straight un matted?

[Dave Tavernier]

32bit, premultiplied

Thanks a million,
Dave

I’m trying to do the same thing. I’m using AE 6.5. I can’t use a targa sequence because I need the audio that goes with the clip. Does anyone have a suggestion?

You have to render the audio file as a separate file from the 32bit targa seq………..make sure it has the exact same number of frames as the targa sequenœ……..the Duet op will marry the two files together.

Thanks a million,
Dave
