I have an After Effects CS4, and it has worked very well, until now.
My problem is this: when I have a videoclip and I used an effect Keying, and Keylight 1.2. Ok, it's doing the job as it should.
But, when I choose Make Movie -command, and I would like to use in Output Module format FLV and Channels RGB+Alpha it's not possible.
I can choose only RGB or Alpha, but not both of them.
What should I do now? I have uninstalled program several times, didn't help.
You can open the AE project in Adobe Media Encoder, choose the comp you want to render and render from Encoder.
If that does not work, give more info:
OS, RAM, Processor, Latest updates to AE?, What version of AE?
