syncing subtitles troubles

framerate

Correcting subtitles framerate may be very important to sync it with audio/video. You can select all subtitles with an editor, and change framerate (for example to 25 from 23.976).

Thereby you should see the video correctly (with VLC or others).

the ultimate solution

If adjusting framerate didn’t fix your problem, you can try an excellent tool (for Linux, Windows and Mac as well): SubSync, whicth works syncing audio with subtitles, and was able so far to solve all my sincing subtitles problems.

You could have a permissions problem working the first time with SubSync, but you will find easily on the web.

avidemux too slow

It’s better use (one of) the following codecs for encoding

  • x264
  • libavcodec MPEG-1/MPEG-2
  • libavcodec MPEG-4
  • Xvid 

so Avidemux will be able to optizmize the CPU usage and will be much faster. And the CPU temperature will be lower.
