MP4 to text
Transcribe MP4 for recorded videos, screen captures, and talks
MP4 is the default video format for phones, cameras, and screen recorders. SnailText pulls the speech out of an MP4 and transcribes it locally, and it can generate SRT or VTT subtitle files for the video.

What is an MP4 file?
MP4 is the most common video container, what phones, cameras, screen recorders, and most downloads produce. It holds both video and an audio track, and it is the format people most often have when they want to caption or transcribe a video.
How to convert MP4 to text
SnailText turns a MP4 into text locally, in four steps:
- Open the Transcribe files screen in SnailText.
- Drop in your MP4 file, or a whole folder of them.
- Pick your output: plain text, Markdown, JSON, or SRT / VTT subtitles.
- 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. MP4 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 MP4 of a talk, a tutorial, a recorded meeting, or a social video, and you want a transcript or subtitles. SnailText extracts the audio and transcribes it on your machine, then can write SRT or VTT subtitle files. Video formats use a one-time codec pack you download inside the app.
MP4 to text and captions, free and without uploading
Most "mp4 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 MP4 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 MP4
The most common reason to transcribe MP4 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.
