i noticed today that AVI exporter enable the "render alpha channel" check-box for cineform also, besides uncompressed.

but there's a lot of others codecs that support alpha channel, but can't be used to export from vegas.

Canopus HQ and UT Video codec for example.

i use a lot to export from programs like Boris Red, that alow "send" alpha channel to all codecs. but vegas have this weird limitation.

any thoughts on that?
