Current workflow for network delivery is export 1080/23.98 ProResHQ master from competitor's NLE, Rewrap and embed 608/708 CC using CineXtools. Files have been checked on various waveform monitors, Telestream Switch and Quicktime player. All show embedded CC correctly.
Network then imports captioned master file into Premiere Pro v14.7 for formatting. From this point, 708 captions are incorrect. They are at the top of screen rather than where originally placed, the text color is grey instead of white, many characters (particularly apostrophes) are incorrect, and entire blocks of captions are missing.
In Premiere Pro v13, 608 and 708 captions playback correctly.
Looking for a workflow/workaround or software revision that corrects this in version 14.
I can provide a sample file to Adobe via DM if desired.
