I don't think I have ever used a movie which contains alpha - there really isn't a typical use-case for that feature. The only compressor I am aware of that will actually encode alpha channels in a movie is huffyuv ( http://neuron2.net/www.math.berkeley.edu/benrg/huffyuv.html). Is this a limitation of avbin or the function that saves the png? The image save certainly supports alpha channels in png - I am having a world of trouble trying to get it to remove the alpha channels. -- Tristam MacDonald http://swiftcoder.wordpress.com/ --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "pyglet-users" group.
