I use Sony Vegas 9. After designing a title with BT that I would like to incorporate with transparency into my video production, I saved it with compression and transparency. No matter which CODEC I chose, when I encorporated the resultant AVI file into my video and selected as its property that it had transparency, it didn't. The only way I could get the title to exhibit transparency in Vegas was to save it as uncompressed. Can some one help me here??
What button didn't I press correctly.
Drop the event on the timeline. Select the event, right click and select "properties" Select "Media" Tab, look to the bottom for "Alpha Channel". Click the drop down menu (black inverted triangle) and select "Straight Unmatted".
Only 32bit video compression has transparency property.
Life would be easier when the plug-in to Vegas is ready.

Did all that and nothing worked. Which codecs use 32 bit compression?

there's only a couple codec's that I'm aware of that support avi transparency.
Lagarith and Huffyuv. There might be one more but I can't recall it right now. Of course, uncompressed supports it because it doesn't require a codec
Both the codecs are free and you can google for places to download them.

Compression *and* transparency is indeed extremely rare. The only 2 codecs I know of that support transparency are Huffyuv and Cineform. Both work fine with BT.
The Huffyuv codec can be found here:

Thank you VERY much. I tried the Huffy CODEC and it worked the first time It is a loss-less compression but still reduced my Title movie from 985MB to 175MB. It also has incorpcoprated within it the ability to invoke a slightly lossy compression YUY2 but when I tried this BF spit back an error relating its inability to find YUY2. I tried contacting the author but only got my EMAIL returned as undeliverable.
BTW Lagarith does not transfer the Alpha channel and hence one cannot get a transparent title into Vegas.
Again THANK YOU VERY MUCH.
