TC overlay & Captions don't work
There are so many posts about open captions in premiere that I am pretty sure no one is reading these posts... I'll add to the open captions frustration anyways: there is no way to render timecode overlay AND open captions on the same export. Generally, I can only make my open captions burn in on the video if I don't send the export to media encoder but directly press export in premiere. After using "Queue" to send the project to Media Encoder, the captions display as burned in on the preview window, they are not on the exported video though
