Steps to Synchronize Video And Subtitles

Watching movies with fast or delayed subtitles is like singing a karaoke song when the subtitles doesn’t sync with it’s music. It can be stressful especially when it’s a movie you like to watch, but which is not in your own language.

Probably, the ability to just pause a movie and drag the subtitle to a suitable timeline position may put you at ease, but this is never the case. So having the option to edit the subtitle so that it will sync with your movie timeline may be a solution you want to look into.

That’s right, there’s a way to re-sync your movie subtitle and we will show you how to do it withKMPlayer, a video player that supports many video formats with options to change, re-sync and even edit your movie subtitle.

3. Click on the ‘A’ icon to edit (re-sync) the subtitles.
   
4. Now you will be presented with a small window of options to edit your subtitle.
   
   The button ‘Sync-’ is to delay the subtitle for the current timeline, while ‘Sync+’ is to fast-forward the subtitle, both changes are by 0.5 seconds. Click on ‘Resync’ if you want to specifically set the delay time.
