BridgeSub Support

BridgeSub aligns, merges, translates, and exports bilingual subtitles for movies you already have. BridgeSub is in development; this page will grow as it approaches release.

Requirements

• macOS 26 or later
• A Mac with Apple silicon

Common questions

BridgeSub doesn't find my subtitles. BridgeSub uses subtitle tracks embedded in the movie and subtitle files saved in the same folder. Choose the movie's folder rather than the movie file, so BridgeSub can see the files next to it. BridgeSub does not search for or download subtitles.

A subtitle track is listed but can't be used. Image-based subtitles, such as PGS tracks from Blu-ray or DVD subtitles, can't be used. BridgeSub works with text subtitles.

Which translation providers work? Ollama, or any provider with an OpenAI-compatible chat API. Keys are stored in the macOS Keychain, and BridgeSub asks you to confirm before each translation run sends subtitle text.

Will exporting change my movie? No. Subtitle files are saved separately, and embedding writes a new MKV or WebM file.
