Make SRT subtitles from an MP4 video
Make SRT subtitles from an MP4 video: upload the file, get numbered blocks with a start and an end time for every line, and download the subtitle file.
Upload the MP4 and the sound track comes back as an SRT file: a block for every piece of speech, with the second it starts and the second it stops. The picture is ignored. The free plan is $0, three files a day, up to 30 minutes each.
How to make SRT subtitles from a video
- 1
Choose the video file
The widget accepts mp4, webm and mov beside the audio formats. The limit is the file itself: up to 30 minutes, and on the free plan 30 minutes per recording.
- 2
Turn the speaker split on
Two people in one frame are two voices. With the split on, the subtitle blocks are marked with the name of the person talking.
- 3
Read one block of the result
The result panel shows the lines with the time they start and end. A name can be fixed in the editor; the corrected wording goes into the TXT and Markdown exports.
- 4
Take the .srt away
The download gives you a subtitle file for that video: numbered blocks, a comma before the milliseconds, the words under them.

The picture is not part of the subtitle file
A video file holds two different things: a picture and a sound track. The subtitle file is built from the second one, and the seconds it writes are the seconds of your own video — put the file next to the picture and the words appear where they were said. The picture is not described and not rewritten: the subtitle file is made from the sound track alone.
Tips
Upload the original recording, not a copy that was re-encoded.
The sound track decides the timecodes, so no video editing is needed.
Turn on the speaker split when two people talk in turn.
A subtitle file and the video belong in the same folder.
Questions this page answers
Does the subtitle file contain the video?
No. The subtitle file holds text and timecodes only, and it comes back on its own: the picture is not in it, and nothing is published for you.
How long a video can I do in one go?
One file may be up to 30 minutes. On the free plan the limit is 30 minutes per file and three files a day, so a long recording has to be split.
Can I change a name before the export?
Yes. The editor in the app lets you correct a word and save it. The corrected text goes into the TXT and Markdown exports; the timed files and the Word file keep the segments of the first pass.
What does the export cost?
The free plan is $0, with three files a day and no card. SRT, VTT, TXT, Markdown and CSV are on the free plan; DOCX is a Pro feature.
