PNG Export: Transparency Issues
Hello all.
I’ve recently upgraded to After Effects CS5 but I’m having some difficulties with the exporting settings.
For a long time, I’ve been using AE not only for making video comps, but also for exportins some static images. I know it sounds wrong, but it’s really familiar to me, and I find it much more convenient and powerful than other problems.
The point is that with the new AE CS5, when I export a png sequence of frames, there’s no transparency for the black/white background colors. Is there a special setting that I have to check, or what else?
Thank you all in advance! 🙂

Check the Channels menu in the Output Module Settings dialog box. You can choose RGB or RGB+Alpha.
Here’s a relevant excerpt from the Help document:
“Channels
The output channels contained in the output movie. After Effects creates a movie with an alpha channel if you choose RGB+Alpha, implying a depth of Millions of Colors+. Not all codecs support alpha channels.
Note: All files created with a color depth of Millions of Colors+, Trillions of Colors+, or Floating Point + have labeled alpha channels; information describing the alpha channel is stored in the file. Therefore, you do not have to specify an alpha interpretation each time you import an item created in After Effects.”BTW, I use After Effects for still-image work, too. 😉
