Hi All,
I'm pretty new to using AS ( I downloaded the now free AS v5) and am currently evaluating how it might work in my pipeline.
I'd like to use it to make simple animations to be used in games. Things like walk cycles and the like.

So, to get to the problem, I have an animation set up and working like I want. I created it with imported PNG images that all have transparent backgrounds (double checked and confirmed). Now want I would like to do is to export as a Quicktime movie (I am on a Mac) preserving the transparency of the images. What I get is a movie with white bg. I've looked all through what little documentation there is and googled it to no avail. So my question is how would I accomplish this?


Also I am using quicktime pro to export the movie to an image sequence if that matters any.

thanks,
-raleigh

For the Codec, choose "PNG" and set the color depth all the way up.

Far as I can remember its in the documentation.

Nonetheless, what you want to do is render with an animation codec, or some other codec, but make sure that the colour depth is set to MILLIONS OF COLORS +. The plus there indicates it includes the alpha channel I think. So, try render to AVI or Quicktime with that 'MILLIONS ON COLORS +' setting and when you import the video into AS again you should see that when you render the movie over something your transparency is preserved.

At least in theory.

Thanks! Looks like that did the trick. I had the color depth set at "Millions" instead of "Millions+"
