Hi
Using CS5
What are the settings to export an alpha channel. When I try following these instructions at this link... http://blogs.adobe.com/premierepro/2010/07/exporting_video_with_an_alpha.html
...and use the quicktime settings, the resulting output file is 720 by 480. Even though my source file is 1440 x 1080.
And when I try to use the Microsoft AVI settings, my only only presets available in the dropdown are DV settings instead of wide screen.
So my question is how do I export a 1440 x 1080 file with an alpha channel to have the same aspect ratio as my source. Either in Quicktime (animation) or Microsoft AVI?
Thanks!

1. Choose appropriate codec (e.g. PNG or TGA for QuickTime container) from Video Codec drop down list (which is on Video Tab), not from the Preset drop down list.
2. Adjust frame Width and Height, Frame Rate etc. as needed.
3. Choose 32 bit from Depth drop down list.
4. Enjoy.
