I use a program called Cinemartin with my Adobe Premiere CS6 on my PC to create ProRes Files.

It’s very easy to install and use…
The software support ProRes 422, 444, and all the rest including H264 and H265…
The ONLY issue I have with the program is it require a very large C drive because it will create a 400GB temp file on your C drive while converting a full length movie.
So make sure your C Drive is at least 1TB…
This is very important to remember…
And trying to trick the program to use another temp location will not work…
It MUST be the C drive…
But I LOVE this program because it give me all the benefits of having a MAC and is very easy to install… It took me about 20 seconds to install the program.
But please remember the huge temp file requirement.
I will say it again… You MUST have a huge C drive that at least 1TB to use this program.
