Why do you use subtitle edit? For example, do you convert your subtitles to another format?
OCR'ed to SRT you can have Subtitle Edit easily remove text for the hearing impaired as explained in the FAQ.

Thanks for letting me know. I may look into this. Although, I'm not sure if I want to open this can of worms!

If I were to do this, do I have to convert my PGS sub tracks to something else first?

If you end up getting the Dune HD Homatics Box R 4K Plus player, or one that supports PGS subtitles, would you then have a reason to use subtitle edit?
No, no reason.

Okay. Well thanks again for your help, I should be all set now.

The only other thing I may do is try to turn a SDH sub track into a non-SDH sub track with subtitle edit. Basically, remove all text for the hearing impaired. Although, I want to see if this involves having to convert a PGS track to another format first.

Yes, you need to convert the PGS track to subrip (.srt) first.

Okay, thanks for letting me know.

It looks like the first step is to extract the PGS subtitle track from the mkv using mkvtoolnix. Then, open the PGS track in Subtitle Edit and convert it to SRT using OCR technology. Next, configure and use the "remove text for the hearing impaired" feature within Subtitle Edit. Converting PGS tracks to text-based formats (like SRT) using OCR can sometimes introduce errors. Therefore, I would need to manually review each track and make corrections if needed. Finally, convert the track back to PGS and then put back in the mkv using mkvtoolnix.

Sounds like too much. Especially, since each track will need to be manually reviewed and corrected if needed.

This is why I asked about changing the positioning that's "baked" in the mkv.
As said before, the BD subs are images, so items can have different positions on the screen and different colors (denoting the actor currently speaking), all of which will be lost when converting to text-based SRTs. It also depends on your player, with Kodi e.g. you can manually move the position on a per-movie basis. Also, Subtitle Edit can parse the mkv so you don't need to extract the PGS sub first. Still, it's OCR which takes time and can introduce errors.
