Runs after every download
Sublarr checks fresh subtitles against the audio track and corrects the offset before you even notice.
Engine chain with fallback
ffsubsync first, alass as backup. If one engine doesn't deliver, the next takes over — no configuration needed.
History at your fingertips
Every sync attempt logged with engine, offset, and status. You see what worked — and can manually retry when it didn't.
When this matters
TV rip with ad breaks, Blu-ray with a different framerate, director's cut with extra scenes — all the classic "doesn't fit" cases. Sublarr detects the misalignment and corrects it. One button to manually re-run auto-sync if a subtitle drifts only in places.
Try it
Install Sublarr, scan your library once — the next episode syncs itself.
