Transparent Background???

I’m attempting to render a QT movie, using PNG images, in Cycles, with a transparent background. The PNG images clearly have a transparent background; however, after rendering, the resulting movie (tried QT, AVI and Ogg Theora), all came out with a black background.

I have checked the “transparent” box under Film; even went into Blender Render and made sure transparency was selected in Alpha. Still no success!

All advice sincerely appreciated.

You need to render using a codec that supports transparency. Quicktime Animation codec is one of very very few that support it

Thanks, Richard. Should have figured that one out myself!
