Add subtitles to a video, and get the SRT too
Some platforms want subtitles burned into the picture. Others want a file they can toggle. InstaZap gives you both from one upload: an MP4 with subtitles on it, and a plain SRT with every line and its timing.
Preset: balanced cut, Subtle subtitles

Why it works for this
Subtitles, not captions
The Subtle style is preset: small, low, white on a thin outline, no word highlighting. It reads as subtitles rather than as a look.
An SRT you can actually edit
One line per cue, broken at the phrase rather than at a word count, timed to the cut video. Open it in any editor, fix a name, save.
Timed to the edit
The subtitles are generated after the silences are cut, on the final timeline, so they line up with the video you're actually posting rather than the one you uploaded.
How it works
- 01
Upload
Drop in the video. Subtitles are preset to on, in the Subtle style.
- 02
Process
The speech is transcribed word by word and the subtitles are built on the cut timeline.
- 03
Download both
The MP4 has the subtitles burned in; the SRT is a separate download on the same screen.
- 04
Use whichever you need
Post the MP4, or upload the SRT to a platform that takes subtitle files.
Questions
Can I get the SRT without burning subtitles into the video?
The SRT is produced whenever captions are on. If you want a clean video and a separate SRT, process with captions on, download both, and use the SRT with a clean export from your editor — or simply process the video twice, once with and once without.
What languages are supported?
The transcription handles most major languages, but the punctuation hint that helps it break lines well is tuned for English. Other languages work; line breaks may be a little rougher.
How do I fix a misheard word?
Edit the SRT. The burned-in version can't be changed after rendering — that's the nature of burned-in text — but the SRT is plain text and every subtitle tool opens it.
Your first 3 are free, and we don’t keep your video
No card to start. The upload is deleted as soon as it’s processed and the result 24 hours after it’s ready. Nothing is used to train anything.
