I have a timeline in Premiere - it has a single prores file and some titles. I wanted to use Premiere to build this since the render engine is so much faster. When I send the timeline over AME, it chokes. If I bring up the output module to view the video, it just stays says "Rendering". AME will force quit if I try to do the encode.
I've tested AME with non-prores files and it seems to work fine.
BTW - AME will work with prores files if they are simply imported directly into the program. But if I send it through Premiere, it will crash up starting the encode.
