How do I enable alpha channel for Prores, Hap, UTvideo Cineform and Quicktimr Animation ?

I can't fine the option

Quote from Vouk

Aha!

Also Quicktime Animation is default Alpha?

Where's Cineform and UTVideo Alpha tick?

A bit unrelated but I ask since you implemented the codecs . What's the codec with Alpha that has quality options? I don't really need lossless huge files like Quicktime.

Why is HAP Q Alpha missing?
