Captions land exactly on the speech. I used to spend evenings nudging lines around by hand.

YouTube kept mangling our brand names. Now I fix them once in the editor and upload a clean SRT.
Uploaded a two-hour recording during lunch — the transcript was waiting before I finished my coffee. The accuracy genuinely surprised me.
Our legal team approved it because processing stays on EU infrastructure. That alone ruled out most of the competition.
Captions split where a human would split them. Viewers stopped complaining about walls of text.
Added captions to every short — average watch time rose noticeably within a month.
No card, no tricks — I tested real files before paying and upgraded a week later because the workflow stuck.
Had trouble with a huge file — support walked me through batch upload the same morning. Rare these days.
An SRT generator turns the speech in a video or audio file into an SRT subtitle file: numbered lines of text, each with a start and end time. BlaBlaScribe writes the subtitles with AI in 120+ languages, lets you check them on a timeline and exports SRT or VTT for YouTube, Premiere, DaVinci Resolve or any player. The first 30 minutes are free, with no card.
Upload the video (or paste a YouTube link), choose the spoken language, let AI write the timed subtitles, review them on the timeline and click Export → SRT. A 10-minute video usually takes a couple of minutes from upload to download.
You get 30 free minutes once, without a card. Short files are transcribed in full and exported to SRT; longer files show the first 10 minutes, and the whole file opens with a minute pack from $5 or a plan.
Yes. Change any word, split or merge lines and drag their timing on the waveform; the SRT is written from what you see.
