Interesting. I find these faux styles for each of these 3:
Subtitles Bold, Ital, All caps, Small caps, Super, Sub, Underline 608 Ital, Underline 708 Ital,Super,Sub,Underline
I checked the possible workaround of exporting a Subtitle track as srt and reimporting as 608 or 708. The export does NOT use all caps. And there is no style code carried.
Does PR have an option for ANY text that will convert to all upper case?
