In short
An SRT file is a numbered list of moments: a start time, an end time and the words under them. Ours builds it from any recording, on every plan, the free one included — $0, 3 files a day, 30 minutes per file, no minute limit.
The case
Why the boundary matters more than the sentence
Subtitles travel further than transcripts, because a player, a platform and an editor all read them. The SRT file is the one they all read: plain blocks, a number, two timecodes and the line that was said. What the generator has to get right is not the sentence but the boundary.
What an SRT file is, and who exports one
00:00:02,000 — a comma before the milliseconds
no official standard; YouTube accepts only UTF-8
Otter exports srt from Pro upwards; for Fireflies and tl;dv no SRT export is stated on the pages we read
SRT and VTT on every plan, the free one included
How to make an SRT file from a recording
- 1
Upload the recording
Any audio or video file up to 30 minutes. The engine returns one segment per line with the time it starts and the time it ends.
- 2
Read the first blocks
The first minute is where a boundary goes wrong: a word cut in half, two voices in one block. Fix the text in the app before you export it.
- 3
Export the file
The download gives numbered blocks with a comma before the milliseconds, written in UTF-8. The same timings are also there as a VTT and as a CSV.
Tips
Check the first block against the sound before exporting.
Keep the lines short; a phone screen shows few characters.
Save the subtitle file next to the video, not inside it.
Questions this page answers
What does one block of an SRT file look like?
A number, then a line with the start time, the arrow and the end time, then the text of the line. A blank line closes the block and the next number begins.
Is the SRT export part of the free plan?
Yes. SRT and VTT are two of the six export formats and they are on every plan: $0, 3 files a day, up to 30 minutes per file and no card.
Why do some words show strange characters?
The format has no official character encoding, so a file written in one code is read in another. YouTube accepts only UTF-8, and that is what our export writes.
Can the subtitles be burned into the video?
No. We produce the subtitle file, not the rendered video: the SRT goes into your editor or onto the platform, and the picture stays in your hands.
