Will it be compatible with my editor?

It should be. It generates a standard-compliant SRT, numbered from one and saved in clean UTF-8, without the byte-order mark that usually causes issues.

Can I change how the lines are split?

You can edit any line before downloading. The timings aren't affected.

What if I'd rather have a VTT?

It's available as an alternative download of the same transcript, recommended if the video plays in a browser.

Does it work on a video with no dialogue?

There has to be speech to transcribe. With instrumental music or ambient sound, the resulting file will be empty, and we'll let you know.

Are the subtitles burned into the video?

No: what you download is a standalone subtitle file, the recommended option in most cases, since it can be corrected, translated, and turned on or off. Burning them into the picture is a separate step done in an editor.

What if the video is very long?

No problem: the limit is 50 GB per file, enough for a full-length film. It's worth reviewing proper nouns before downloading, since that's where most errors occur.

About this tool

SRT is the standard subtitle format for video editors, platforms and players. Generating one from an MP4 consists of transcribing the internal audio and writing the timings in the correct format, which is exactly what happens when you upload the file.

Reviewing proper names, acronyms or specific terminology happens on the same screen, line by line, without modifying the timings.

Features

A correctly formed SRT: numbered from one, UTF-8 with no BOM, and commas in the timings.
Lines adjusted to what fits on screen, not just by character count.
Speaker identification, something a plain text dump doesn't offer.
The same transcript is also available as VTT, DOCX, PDF, CSV or JSON.

Use cases

Video editing

Premiere, DaVinci and Final Cut import SRT directly into the timeline.

Publishing on platforms

The subtitle field on any platform expects exactly this format.

Archiving

An SRT alongside the video, sharing its name, keeps it permanently searchable.

In detail

The hard part isn't writing, it's synchronising

Transcribing what's said in a video is relatively quick; giving each sentence its exact start and end second is what takes the most time. Ten minutes of video can easily contain two hundred subtitles, each requiring two marks to the millisecond.

That synchronisation comes already solved. The timings are calculated against the audio of the file itself, so they align automatically once the SRT is attached to the video, with no drift or manual global adjustments needed.

How to add the result to the video

If the destination is YouTube, the SRT is uploaded separately via Studio and becomes an optional subtitle track. If the destination is social media, most platforms prefer subtitles burned into the picture, done in an editor by importing the SRT as a text track.

In Premiere and DaVinci, simply add the file to the timeline: it appears as a subtitle track with the timings already calculated. For a desktop player, save the SRT next to the video with the same file name.
