What an SRT file is

An SRT is a numbered list of cues, each with a start time, an end time, and its text. That is the entire format — which is exactly why it works in YouTube, Vimeo, Premiere, DaVinci Resolve, VLC, and essentially every social platform.

Getting the line breaks right

Most auto-generated SRTs are technically correct and hard to read, because they break lines at an arbitrary word count. "We went to the / shop on Tuesday" reads worse than "We went to the shop / on Tuesday", and the difference compounds over a full video.

There are two segmentation modes here. Fixed word count is predictable. Natural sentences breaks on punctuation and caps at a maximum length — for dialogue it almost always reads better.

Editing without breaking sync

Every word is timestamped individually, not just each cue. So when you split a line in half, the second half starts at the moment that word is actually spoken rather than at an estimate derived from character counts. That is the difference between subtitles you can edit and subtitles you have to accept.

Reading-speed guidelines

• Aim for 15–20 characters per second. Faster and viewers skim instead of reading.
• Around 42 characters per line, two lines at most.
• At least one second on screen per cue, and no more than about six.

Frequently asked questions

Do I need an account?

You can transcribe a clip of up to 5 minutes as a guest to see how it works, but downloading the SRT or FCPXML file requires a free account. Signing in also gives you 15 minutes and 3 transcriptions every month, and lifts the 5-minute file limit.

What languages are supported?

Transcription runs on Whisper large-v3, which handles most major languages and detects the language automatically. You can additionally translate the result into over ten target languages while keeping the original timing.

Can I convert SRT to another format?

Yes — the same transcript exports as FCPXML for Final Cut Pro. Both come from one set of word timings, so switching format never changes the sync.
