What is an AVI file?

AVI (Audio Video Interleave) is Microsoft's long-standing video container, dating back decades and still common in older recordings, archived footage, and legacy camera output. It is widely recognized but ages unevenly, and some modern tools no longer read it cleanly.

How to convert AVI to text

SnailText turns a AVI into text locally, in four steps:

  1. Open the Transcribe files screen in SnailText.
  2. Drop in your AVI file, or a whole folder of them.
  3. Pick your output: plain text, Markdown, JSON, or SRT / VTT subtitles.
  4. Run it. The transcript is saved next to your files or wherever you choose.

The Whisper speech model transcribes on your own machine, so the audio never leaves your computer and there is no per-minute charge. AVI is a video format, so SnailText uses a codec pack it downloads once inside the app. After that one-time download it works offline, and transcription runs fully on your machine.

You have an AVI from an old camera, an archive, or a legacy recording, and you want a transcript or captions. SnailText extracts the speech and transcribes it locally, then can write SRT or VTT. Video formats use a one-time codec pack downloaded inside the app.

AVI to text and captions, free and without uploading

Most "avi to text online" tools upload your file to a server and cap you at a few minutes unless you pay. SnailText is the opposite: it transcribes AVI on your device, so nothing is uploaded, there is no length limit beyond your own memory, and the free tier has no per-minute meter. That makes it a fit for anything sensitive, recordings with names, client video, or private notes, where sending the file to a web service is the thing you want to avoid.

Generate SRT and VTT subtitles from AVI

The most common reason to transcribe AVI is captions. Pick SRT or VTT before the run and SnailText writes a subtitle file you can drop straight onto the video. It also exports plain text if you just want the transcript:

  • · SRT and VTT subtitles with phrase-level timestamps, ready to drop onto a video.
  • · Plain text (TXT) for a clean transcript you can read, search, and edit.
  • · Markdown with a heading per file, handy for notes and docs.
  • · JSON for feeding the transcript into your own scripts or tools.

AVI to text FAQ

Can I transcribe an old AVI file?
Yes. SnailText handles AVI through its codec pack (a one-time download), then extracts the audio and transcribes it locally with the Whisper model. It can also export SRT or VTT subtitles if you pick them before the run. Nothing is uploaded.
Do I need to convert AVI to MP4 first?
No. SnailText reads AVI directly through its codec pack, so there is no conversion step. That is useful for archives full of older AVI files you would otherwise have to convert one by one.
Is AVI transcription free?
SnailText's free tier transcribes locally with the compact Whisper models, no account and no per-minute meter. Pro adds the larger, more accurate models and an optional on-device AI cleanup pass, $7.49/mo or $89/yr for up to 3 devices.
Can I transcribe a whole folder at once?
Yes. Drop a folder (or several files) into the Transcribe files screen and SnailText processes them one after another, writing a transcript for each. It scans the files directly in the folder. You can also drag and drop files straight in.
Can I get SRT or VTT subtitles?
Yes. Pick SRT or VTT as the output before you run the transcription and SnailText writes a subtitle file with phrase-level timestamps. Choose it up front, since subtitles are produced during the run. You can also export plain text, Markdown, or JSON.
What languages can it transcribe?
SnailText transcribes in the full set of Whisper languages (99), and can auto-detect the language or let you pick. Everything runs locally, so multilingual transcription works with no internet after the model is downloaded.
