SRT for editors, platforms and players; VTT if the video plays in a browser with an HTML5 `track` element. You can download both formats.

Can I edit the text before downloading?

Yes. It's worth reviewing proper names and technical terms: click the relevant line and correct it without affecting the timings.

Do I need to adjust the timings manually?

Almost never. They're calculated from the audio itself, not estimated, so each line starts exactly where the sentence begins.

Does it work in other languages?

Yes. Requesting translation gives you both tracks in the same operation: the original and the translated one.

Can I change when each subtitle enters and leaves?

The text is edited here; the timings arrive already calculated against the audio, which is the most time-consuming part to adjust manually.

Does it work for subtitling in another language?

Yes. Request the translation and the subtitle file is generated in the translated language, segment by segment, keeping the same timings as the original.

About this tool

Creating subtitles manually is the slowest part of any video production: play, pause, type, and then just as much time again adjusting the timings. This tool handles the first pass in about three minutes per hour of video, leaving for human review only what genuinely needs it: a proper name, a technical term.

The result isn't a block of text: the lines are split correctly, the timings are synchronised to the millisecond with the audio, and when there are several speakers, each line indicates who's speaking.

Features

Timings to the millisecond, calculated from the audio, not estimated.
Lines split to a readable length, instead of full paragraphs.
Speaker identification when the recording contains several voices.
Over 90 languages, with a translated track available alongside the original.

Use cases

Social media video

Most viewers watch video without sound; subtitles are essential.

Accessibility

They make content accessible to people with hearing impairments.

Courses and training

A subtitled class can be searched by content, in addition to serving as a transcript.

In detail

How much text fits in a subtitle

The usual convention is two lines of about forty characters, visible on screen long enough to read comfortably: between one and seven seconds, never under a second. This isn't an arbitrary rule; it's what became standard in television and cinema over decades, and players assume it's being followed.

Segments are split according to that criterion, not sentence by sentence. If you edit the text afterwards to fix a name, the cut point doesn't change: what changes is what's read, not when each subtitle appears and disappears.

SRT or VTT? It depends on the destination

SRT when the destination is an editor, a desktop player or a platform's upload field. VTT when the video is embedded on your own website, since the browser's player only supports that format.

Both can be downloaded from the same screen without transcribing again. If you later need to convert between the two, the relevant converters are available with no account required.
