Here's a trick to export the alpha channel:
1) Select the camera layer
2) Press the CHANGE EFFECT... button and select Effects/Export/CheckAlpha.fx
3) Set the FX SHOW ALPHA CHANNEL property to 1
4) Choose FILE > EXPORT AS MOVIE... and select UNCOMPRESSED AVI WITH TRANSPARENCY
The CheckAlpha.fx that comes with the installer has problems rendering the alpha channel at the borders of the screen. This is fixed in the version attached to this article.
Beyond cool, thanks Michiel!

how to create an transparent background in bluff?

mrbernd, the background is always transparent.
It's the layers in front of it that make it non-transparent. For example a full screen background picture removes all transparency.
