I’m doing a complete overhaul for my subs so stay tuned… 😃
But I found a weird problem. It seems that sub tracks have different timing when used in mpv vs. MPC. I can’t play SW 4K smoothly on MPC so I’ve always had to use mpv, also when re-adjusting the timings. There seems to be 2 frame difference between the players. That’s pretty weird, does anyone know the reason?

I know PGS subtitles can be off by a frame from what you intend because the internal timecodes use 24.000fps, even for 23.976 subtitles, and rounding issues can potentially send a subtitle to one frame or another. Presumably since PGS is more like the native subtitle format and even it has issues, text-based subtitles could potentially have even more due to the extra conversion. And, of course, there are just plain errors. For most people, if the subtitle is off by two frames, nobody would even report the bug, let alone fix it.

Yeah, sorry, I meant srt subtitles as I use them to work with. It’s not a big problem but mainly it’s apparent for example during ALTA, beginning of SW logo, and Huttese subs as their sync differs. So not sure what is the “right” timing, MPC, mpv or something else.
