robotpin / srtsync

Automatic synchronizer of subtitles based on voice activity in the video

Abandonned project

This project was just a Proof of Concept, and is not maintained anymore.

The project ffsubsync does the same thing but better.

srtsync

Automatic synchronizer of subtitles based on video or other subtitle

The synchronization to another subtitle is less accurate and EXPERIMENTAL
