ProRes 4444.

If you need QuickTime, but can deal with a separate movie for your alpha channel, you could use a regular uncompressed 10-bit codec and add an Alpha-only uncompressed 10-bit output module to your render queue item.

If it doesn't really need to be wrapped in QuickTime, maybe you could use a PNG, TIFF, PSD, or OpenEXR image sequence.

Is it possible to render ProRez 4:4:4 with alpha?
seems that is not an option in the output module.

(this might be what you were saying, perhaps I misunderstood you)
