Since the recent update to Media Encoder 2014.1 and Yosemite media encoder will not render premiere sequences. Here's what I'm doing.
Opening Media Encoder
Add Premiere Pro Sequence
Click Render
... Nothing happens, it gives me the option to stop, but never actually starts.
I can't quit the application. I must force quit.
When I export from premiere and choose to add to media encoder que nothing happens. Media encoder starts but I have to force quit.
Exporting from premiere works fine.
