So I'm having issues with my computer at the moment.

 

I have a video I'd like to export with the alpha channel. I don't care what Codec it is, I just need the alpha channel. I tried exporting as QuickTime with the Apple ProRes 4444 including alpha channel, and it doesn't render video, only sound. I tried exporting QuickTime without alpha, and it still didn't work.

 

MP4 renders, but I need the alpha channel.

 

Does anyone have any recommended codecs or thoughts on what to do? Thanks!

Would you check the setting of Video Output in After Effects?

 

Composition menu > Add to Render Queue > OutputModule Lossless and click it > Output Module Settings windows open > Main Options tab > Video Output Channels: RGB + Alpha

 

If you need only Alpha channel, you click Format Options next to Channels and turn on Render Alpha Channel only.
