Currently the mxf export can only embed the CC file using Teletext format 801.

Please can we have support for more options within OP47 type banner?

Currently there's no way to select a format type to desired output say 888, customary for broadcast UK broadcast.

Since captioned dialogue typically is preferred to be on screen for about 0,3 sec/word (acc. to BBC guidelines) it would be a great help if you could see the duration of each caption when hovering over a caption and in the Caption work panel rather than just the in- and out points. My brain really hurts :-D when I'm trying to calculate the length of each and every caption in a full length film. Thanks and have a nice day!

Whenever I'm working on Closed Captions and I try to adjust the audio level, my cursor disappears and I can't work in the project anymore. I have to quit the program through keyboard input and start over again. It's a bug that has resulted in so much frustration and having to start over with projects. Please fix this!

open captions have styling options such as font etc, but the default gap between the lines is too big and you still don't have the option to change this gap (leading).
Lacking that option will still make this tool irrelevant.

This refers mainly to open captions for non-TV usage.

The position of captions does not allow for negative values anymore. So we are stuck with the left margin (x=0) being roughly at the standard "title safe" position. However, if your project is not limited by TV-standards and you want to use the entire screen width for subtitling, you can't. Any title will just go offscreen on the right with no way to re-center it. This was working in CC 2017 when PPro yould accept x values below zero. Please change this back again.

In 708, After the first couple, I can't get the boxes to switch colors or the text to switch colors right. I am not asking the world here-because I know there are few options in the true closed caption section, but with the rise of watching without sound on social media-and switching this off and on at will in YouTube, the elements are so buggy as to be unusable. Resetting workspace, copy new project etc, does no good. This is a professional level editor. Fix these bugs so it works correctly!

YOu were able to bring in a OP47 MXF and edit with it and preserve the VANC - Now in the most recent releases it stripes it out even with Transcode ANC / VBI selected, it worked in V11 but for some reason it is gone, Also if you create a Australian OP47 (most recent) you can not embed only do as Open ?? Thats madness

The "set start timecode" option should also apply to a sidecar caption that goes with a video file.

If we use caps by importing a srt file, could you please set it to ON in export automatically. So it remains What You See Is What You Get and you cannot forget the subtitles on export.

What about having a tool that makes subtitling easier. If you could import a textfile with gaps between the text that belongs together and having a shortcut that hits a new subtitle in whenever you hit it. You could easily read your translated text, see when the speaker starts speaking (on the audio track) and after watching the whole video for once, just hit enter and everything will fall in place. That would be amazing!!!

Noticing that if you make changes to the fonts and then keep tweaking, eventually Premiere just stops updating the preview of the captions and you need to close Premiere and manually clear the caches to solve.

Also finding that the drag to zoom will often get stuck in that target cursor mode not allowing you to do anything except restart Premiere to get your cursor back.

Overall the whole caption system in Premiere is pretty buggy.

Why doesn't PP have a solution in place or take files like .vtt, .srt or .sbv which I can extract from YouTube.
