Hi. I want video with alpha channel in Prores codec in Media Encoder, but nothing happening. Video renders with black background not transparent. Can someone explain, what am I doing wrong?
Here my configuration:

You're not doing anything wrong. Alpha channel support is still on my TODO-list.
Thank you for your answer!
Hello! I'm just interested, what about your TODO list and alpha channel position in it?)
Thanks for reminding me.
Can you please try the premiere connector 1.2.0 and tell me if it works?
You have to choose a pixel format with an alpha channel to enable this (like you showed correctly in your screenshot above).
Strange, I tried again with default settings from your first screenshot, but nothing changed.
Same situation with another simple video i created.
Please be aware, that you can't just test for transparency by playing it with MPC-HC or any other player. You need to import it in a project again. In MPC-HC the transparent video looked faulty to me too.
Nope, I also tried the same as you did on yours second screenshot. Maybe my problem is, cause I use older version of the Premier Pro.
Are you using Connector 1.2.0 and Voukoder 3?
Yes, also reinstall them couple times, thought it might help.
Hello again. I just want to say, that on newer versions of the Voukoder 4.1 and the Premiere Connector 1.2.2
I still don't get Alpha Channel on the Prores 444/442. I thought maybe you'll be interested in log file.
Found the issue. You don't get any alpha channel information because the connector you're using does not supply any alpha information:

For some time now the connectors provide a different format:

So it seems you are still using a very old connector, even if you have installed the latest one. Please perform these steps:
This should help.
Please try connector version 1.2.4. It seems your processor is not capable of the AVX/2 instruction set and I had to make a little change for this path.
OMG! Thank you! It works! It still shows "Voukoder" and also yuv444p16le, but works!
Big Thanks!!!
Also I attached Log File if you interested:
Take a closer look
it is yuva444p16le
YES! You're a magician! Marvelous!
Thank YOU!
