Alpha Channels (again)

Hi, I don’t understand how using the alpha channel is still so difficult. Why are we limited to only 3 ways to export them? Animation is huge and limited to 8 bit colour, tiff is incredibly unwieldy to use when working with massive files, and png is just…urgh.

You’ve added dnxhr codecs, which support alpha, why not let us export with that in 10 or 12 bit with alpha?
