I've got a client that's requesting delivery for this giant screen to be a ProRes 4444 10 Bit quicktime. Is this even possible? My understanding is that ProRes 4444 is 16 bit w/ alpha channel. Remove the alpha channel, you get 12-bit. R, B, & B channels equal 4 bits each, equalling 12 Bit. If they are asking for 10 Bit 4444, is that even possible?

Before I respond to the client, I am hoping to have my head wrapped around this subject. I've got no editorial support here, so I'm trying to keep the workflow in After Effects, if it's possible to render/export at this spec.

Thanks for reading!

You are confusing bits per channel with bits per pixel (or picture element). It's 8-, 10-, 12-, or 16-bits per channel, which refers to the number of graduations from zero to full for each channel (e.g. 256, 1024, etc.). In practice, set the AE project to 16-bit and export using "Billions of Colors."

Here is some reference information on the codec:
