I am a youtuber.I always use AE to make some titles and export it to PR.
I usually use mov format and RGB+Alpha way to render.
Last week I found the bset encoder plugin in the word -voukoder.
It is perfect and It has all the features I need, expert RGB+Alpha way.
I had read your some answer in other thread.You say it is in your Todo.
I just want to say: It will be faster.Becase I really need it.
In the end.Thanks of you developing.
