Does anyone know whether it's possible to export a CT .avi file with an alpha channel?  It seems that although CT can handle alpha channels internally, when it comes to media export the codec strips out any alpha information.  I am trying to export a CT sequence into Flash CS3 with a transparent background.  It works fine if I export/import as a .tga sequence, but not as an embedded .avi video.

Choose the Intel Indeo Video 4.5 codec to export an avi with alpha transparency. There is supposed to be a HuffyUV codec and a supposedly higher quality lossless codec named Lagarith that does the same but I don't have either installed on this machine to try it - yet. I think I'll go get them while I'm thinking of it. I tried the Indeo 4.5 codec yesterday on a project and it worked great when working with the avi output from CT5 beta in Premiere Elements 3.0.

Update:
I just tried 4 codecs with CT Media Studio 4.6. Indeo 4.5 and 5.1 work to output alpha transparency - be sure to set that up in the configuration settings during the save of the avi file.

Then I tried HuffyUV 2.1.1 and Lagarith 1.3.14.0 and both work really well. Here too you need to have the settings correct when saving the avi to use alpha transparency/RGBA, whatever the particular codec configuration setting uses to describe this feature.

I hope this info helps someone in the future even if the original question was posted a month ago.

Avi and transparency with Crazy Talk 5 only seems to work with sequential Targas.

Tried all the other exports and only that seems to work.  Any one at Reallusion have any ideas?

Thanks!
