Crawls a directory recursively, transcribes every video it finds using whisper.cpp (on-device, fully private — nothing is uploaded anywhere) and writes an .srt sidecar file next to each one. Already-transcribed files are skipped, so re-running is fast and safe.
While a file is transcribing, segments stream into a growing .srt.part file so progress is never lost; it's atomically promoted to .srt on success, so a crash or cancellation never corrupts a finished subtitle.
Supports .mp4, .mkv, .avi, .mov, .m4v, .webm, .ts, .flv, and more.
Provides both the add-subs-to-videos CLI command and an "Add Subs to
Videos" desktop GUI launcher. The GUI offers drag-and-drop, a file table
with live per-file status (Pending/Processing/Done/Skipped/Failed) and a
clickable log icon per row, a model dropdown showing download progress,
and auto re-run every 10 minutes so it can be left running unattended to
pick up new files as they appear.
Usage: add-subs-to-videos /path/to/videos add-subs-to-videos /path/to/videos --model large-v3 --language en add-subs-to-videos /path/to/videos --force add-subs-to-videos-gui # or launch "Add Subs to Videos" from your apps menu
