brAutosub

Deep engineering system

Find the videos in your folders that have no subtitles and caption them for free on your own computer.

brAutosub showing its folder scanner silence filter and local batch subtitle queue

Current status

Local Python and C++ batch captioning tool that generates subtitle files on your own machine.

Overview

Automated local speech-to-subtitle tool that scans your media folders for uncaptioned videos and generates accurate `.srt` and `.vtt` subtitles right on your own computer.

Why it was built

Cloud transcription services charge by the minute and require uploading private recordings, while basic local transcription scripts often repeat phantom lines during quiet pauses.

Why it helps

Runs privately on your own computer at no cost, remembers which videos are already captioned, and automatically cleans up repeated lines during silent sections.

What you can do

Scans nested folders automatically to find videos missing subtitle files
Normalizes audio levels before transcription for clearer speech recognition
Built-in cleanup pass that strips repeated phantom phrases during silence
Resumable batch queue that never re-processes already-captioned videos
