Subtitles out of sync in VLC

Quick fix while watching

• Windows/Linux: G makes subtitles appear earlier, H later – 50 ms per press.
• macOS: H earlier, J later.
• Exact value: Tools › Track Synchronization (Mac: Window › Track Synchronization) › Subtitle track synchronization, in seconds.

Tip: pause on a clear line of dialogue, note how far off it is, then type that value.

When a constant shift isn't enough

If the subtitles start right but drift further off as the film goes on, the frame rate differs (typically 23.976 vs 25 fps). A single delay can't fix that – see frame-rate conversion or use two-point sync.

If they are right, then suddenly off after a certain scene, the subtitle was made for a different cut. Shift from that line onwards.

Make it permanent

1. Open the .srt in Cuemend (add the video too if you want auto-sync or a preview).
2. Enter the offset you found in VLC, or use two-point sync (give the right time for an early and a late line), or let auto-sync match the subtitles to the film's audio.
3. Save. Keep the same file name as the video so players pick it up.
