Out-of-sync .srt after converting from a .sup file

[EloyFarina]

Hi

After extracting the .sup file from a .mkv, I open it with Subtitle Edit and convert it to .srt using Tesseract 5.3.3, then load .srt into the movie but timings are out of sync. Even after adding or reducing delay to all lines, they go out of sync again after a couple of minutes.

Strangely, when I load the .sup file that I extracted directly into the movie, the timings are correct.
So, I think that issue happens on how Subtitle Edit reads the timestamps of the sup file.

This problem has occurred multiple times with .sup files.

Has anyone else experienced this issue? Any assistance would be appreciated.
