Batch subtitle synchronization tool based on FichteFoll's fork of Sushi.
Sushi is not perfect, an can output subtitles with broken timings. You should check if the subtitle was synced correctly on completed tasks with high shift average (10s or greater).
pip install sushi-batch
- FFmpeg
- mkvmerge from MKVToolNix (Optional)
Add the required binaries to PATH or install them via a package manager like Chocolatey. You can also copy the executables to the directory from which you run this app (not recommended).
Most distros link installed packages to PATH automatically, so just make sure to install the required apps via your distribution's package manager.
Sushi works by finding the closest similar pattern between a provided source and destination audio track. The obtained shift value is applied to the output subtitle, which will be synced to the destination track.
You must provide:
- A subtitle file (ASS, SRT, SSA).
- The original audio track for that subtitle.
- A destination audio track to sync the subtitle to.
You only need to provide:
- A source video file which contains a subtitle.
- A destination video file.
You can select a specific subtitle or audio track from the video files. This allows you to add multi-language subtitles for a specific audio track.
FFmpeg will take care of extracting the audio and subtitle tracks for processing.
This program allows for:
- Batch synchronization of files within selected directories / selected files.
- Queueing of synchronization tasks
- Merging synced subtitles with destination video (more below)

If mkvmerge is installed, the app will automatically merge the synced subtitle to the specified destination video file. The merge can also be started manually inside the Job Queue section.
You can customize the arguments used for merging via the app's settings.
