How to set the synchronization of subtitles on VLC?

There may be times when you want to associate a video with a closed caption file from a third party.

Sometimes, the synchronization between audio, video and text leaves something to be desired, and we end up with a translation that is not displayed simultaneously with the dialogues heard.

VLC allows you to easily correct the shot, via two options. The first is to use the keyboard shortcuts:


  • pressing the H button delays the display of the subtitles by 50 ms. The offset and the display of the corresponding instruction on the screen are immediate.

  • Conversely, the G key is used to advance the display of the subtitles. With a little trial and error, we usually manage to reestablish synchronization.

With some, however, it will be necessary to be more precise.

It happens that a subtitle file has been produced from a video source whose display speed differs from the file played at home.

We thus end up with subtitles which gradually shift from the audio / video track.

Here, we can try to correct the situation via the Tools menu, Track synchronization, by playing with the Subtitle speed parameter.
