Convert AVI to a VTT caption file
AVI is one of the oldest video containers, still common in archival footage, older camcorder exports, and legacy software output. SnailText extracts the audio, transcribes the speech with the Whisper model, and writes a phrase-level VTT, all on your machine.
You get a separate .vtt file you can attach to the video in any player that accepts WebVTT or upload to a streaming platform. AVI uses a one-time codec pack the app downloads for you.
How to convert AVI to VTT
- Open the Transcribe files screen in SnailText.
- Add your AVI video (or a folder of videos).
- Choose VTT as the output before you run it.
- Run it. The .vtt file is saved next to your video.

AVI to VTT free, without uploading the video
Online tools that accept AVI upload your video to a server. SnailText does it locally: the video stays on your computer, there is no length limit, and no watermark. AVI uses a one-time codec pack the app downloads for you, then runs offline.
If you need SRT instead of VTT, the AVI to SRT page covers that. SnailText exports both, you just pick before the run.
