Subtitles out of sync

[DYNAMIC]

So the command you wrote here is for what machine ?
and also would this work if for example I used media encoder to do the job ?

Try remuxing the video.  In my testing the issue doesn't occur on the files I've encoded myself, but files from other sources sometimes have issues with SRT subtitles desyncing.  Remuxing the video appears to work.

Code:

ffmpeg -fflags +genpts+igndts -i "/path/to/video.mkv" -map 0 -codec copy -max_muxing_queue_size 2048 -max_interleave_delta 0 newFile.mkv
