pums974/srtsync: Automatic synchronizer of subtitles based on voice activity in the video

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

The project ffsubsync does the same thing but better.

Automatic synchronizer of subtitles based on video or other subtitle

Largely inspired by py-webrtcvad

It can only stretch and shift subtitles for now.

The synchronization to another subtitle is less accurate and EXPERIMENTAL

• python 3.6+ (f-string)
• ffmpeg for audio extraction
• numpy / scipy for synchronization
• pysrt for reading and writing subtitles

And optionnally

• pymediainfo for accurate detection of a video file
• webrtcvad for voice activity detection

pip install srtsync
