Problem: FPS subtitle

[whitetfg]

Hello,
its my first post here, so i hope that iam doing correctaly.

I downloaded a film and a subtitle. But when i load the subtitle, it pass to fast. First i see the subtitle, and after i listen the audio. I think the problem is on frames, right? Could you help me?
Thanks since now.
and sorry for my english.

If the delay between the subtitle and the audio is the same along the movie, then you should add some seconds to the whole subtitle file. If not, then the framerate it's different and you should change the framerate for the subtitle. In both cases you need a subtitle editor (such the one built in BSPlayer). Ir you can download a subtitle with the requiered framerate.

I have one question: I want to change the framerate of subtitles in the subtitle editor (from 25 to 23.9), so I fill the source framerate (25) and the target framerate (23), but the change is too small.
Is there a bug or am I doing something wrong? (It's the latest version of BS.player 2.62).
Thank you...

Let's see:
1 hour of movie is 3600 sec * 25 fps = 90.000 frames
1 hour of movie is 3600 sec * 23,976 fps = 86313 frames

and that is in an hour.
86313 / 90000 = 0,96 or 96 %..so, there is a 4% difference. So, the frame 100 become 104 if you chage the framerate from 23,976 to 25 fps.

Yes, that's true, but it doesn't work by me with .srt subtitles: the subtitle editor adds the same time at the beginning and at the end (approximately 2s).

Yes, unfortunately there seems to be a bug in subtitle editor.
Loaded 23.976 fps subtitles

After pressing convert (from 23,976 to 25 fps) all I got is 2 sec substracted from subtitle and not a real conversion.

Moved to bug reports.
