Thanx for the response. The reason I need to render to quicktime mov files is that I need alpha channels in the movie file, and as far as I know quicktime avid codec is one of the few video codecs that supports alphas.

Appreciate the replies! I just got it working with the microsoft video 1 compressorat 720x405. I think the problem was that I had changed the document window size during animating, with out maintaining the ratio. Those of you who have a lot of RAM on your computers; How long does it take for you to render 100 frames of a quite detailed scene at the above ratio (720x405)? I just wanna know 'cause it took almost 2 hours on mine.

thank you very much tasmanet!!

thanks guys. I actually ment a wall clock, any chance of finding that?
