Hi everyone,
I want to share GenSRT, a free open-source Windows tool I've been
working on for generating SRT subtitles from video using OpenAI Whisper.
v1.2 just released.
What it does
- Drop a video, click Generate, get an SRT (and a VTT in the same place)
- Edit cues in a built-in player with live subtitle preview — split,
merge, delete, edit text- Translate to 100+ languages via Google Translate (or MyMemory as
fallback)- Burn subtitles into a copy of the video with one click
- Bundled ffmpeg — no separate install needed
- SRT filenames are Plex / Jellyfin / Kodi-compatible
What's new in v1.2
Better support for non-English languages, especially Indic. Community
fine-tunes of Whisper (like vegam-whisper for Malayalam) previously
couldn't handle long-form audio properly — they'd transcribe the first
few seconds and stop. v1.2 fixes this by slicing audio along silences
and transcribing each piece independently.
If you've tried generating subtitles for Indian-language content and
been disappointed, v1.2 is worth a look. Set the model dropdown to
smcproject/vegam-whisper-medium-ml-int8_float16 for Malayalam —
the model auto-downloads on first run.
Screenshots
[Insert a couple of screenshots here — the main UI shot with subtitles
playing, plus maybe the model picker.]
Requirements
- Windows 10 or 11
- NVIDIA GPU recommended (any with ~2 GB VRAM works) — runs much
faster on GPU- CPU mode also works if you don't have an NVIDIA GPU — about 3× slower
than GPU but produces the same output. Tested on Intel Arc 140V (Lunar
Lake laptop).- ~2 GB free disk for the model on first run
