SRT Subtitle Generator

Caption-length cues and clean timing. Download SRT or VTT for your editor.

or

For links

Uses captions when they are good, at a tenth of a minute per minute of video. Listens when they are not.

Free to try, no sign-up. Files are transcribed from their audio. The result page exports SRT and VTT.

How it works

  1. Add a file or a link

    An audio or video file, or a public video link.

  2. Scribiz writes the cues

    Words and their times become short cues, with speaker labels where they apply.

  3. Download SRT or VTT

    Import the file into your editor or YouTube Studio.

How a few sentences break into cues. Eight words, a comma, a full stop or a pause each end a cue.

Where cues break

Cues are built from words and their times. These rules decide where one ends. A line holds at most 42 characters and a cue at most two lines, so it stays easy to read.

Files, not burned-in text

SRT and VTT are sidecar files. Viewers can switch them off and you can edit them later. Scribiz does not burn subtitles into the video. That is a job for your editor, which also lets you pick the font, size and position.

A file gives word-level times, so cues are cut at real word boundaries. A YouTube link that has good captions follows YouTube's own timing instead. A video file works too: the browser pulls out the audio and only that is uploaded.

Into your editor or player

Run the file, then open Export on the result page and choose SRT or VTT. Import the SRT in Premiere Pro or DaVinci Resolve, or upload it in YouTube Studio under Subtitles. VLC and most players load an SRT that has the same name as the video and sits next to it.

Have a YouTube link, not a file? The YouTube subtitle downloader takes the link and uses the captions the video already has. For plain text, use audio to text or video to text. The format docs show every cue rule and sample.

Limits

Files up to 100 MB in the browser, and about 50 minutes of audio from a video. Links work too. No translation yet. The file is in the spoken language. Timing is word-level for files and sentence-level for a link that Google has to read directly. Without an account: files up to 15 minutes and 10 minutes a day.

Questions

SRT is the safe default that nearly every editor reads. VTT is the web version for HTML5 players and can carry styling.

Download the SRT from the result page. Premiere Pro takes it through File, Import, and DaVinci Resolve through File, Import, Subtitle.

No. Scribiz writes subtitle files. Burning them in happens in your editor, where you also pick the font and position.

Files carry word-level timing and cues are cut at those words. A link that YouTube will not let us download is read from the link instead, with sentence-level timing that can drift by a couple of seconds.

Yes. Paste the link instead of a file. Good captions are used as they are, and otherwise Scribiz listens. The YouTube subtitle downloader is built for that.

Not yet. The file is in the language that is spoken.
