AutoSync Subtitles
A Stremio addon that retimes subtitles to match your video, so they stop running early, late, or drifting.
If the button does nothing, copy the link and paste it into the search box on Stremio's Addons screen.
What it fixes
- Subtitles that are early or late by the same amount all the way through.
- Subtitles that start fine and drift, because they were made for a different frame rate.
- Subtitles made for a different cut of the film, such as one with ad breaks removed.
How it works
- When you play something, Stremio asks the addon for subtitles for that title.
- The addon looks up the subtitles OpenSubtitles has for it, in every language.
- It compares when people are speaking in each one. Subtitles that agree were made for the same release of the film.
- It retimes the best subtitle in your language to the releases most likely to match your video, and lists them in the player's subtitle menu.
It can offer up to four versions. The first is the most likely match; if it is off, try the next.
What it sees
Only what Stremio sends to any subtitle addon: the title's ID and, when available, the video's file name, size and fingerprint. There are no accounts, no tracking and no stored history.
Limits
- It can only retime subtitles that exist on OpenSubtitles for your language.
- The first time a title is opened it can take a few seconds; after that it is quick.
