How to Sync Movie Subtitles in VLC on Mac and Windows With Hotkeys

VLC lets you play videos or films with subtitles on Mac or Windows. It syncs subtitles to match them with the audio track or images. You can stop the subtitles from coming too fast or slowly by pressing some hotkeys on your keyboard. These shortcut keys vary based on your operating system. If you use Windows, press “G” or “H.” Alternatively, press “G” or “J” if you use Mac.

  • If a subtitle pops up earlier than the sound or scene, press H on Windows or J on Mac to delay it. Likewise, this will delay the subtitle by fifty minutes.
  • Continue pressing these shortcuts until you achieve a proper sync between the movie subtitles and sound.
