Overlong captions become readable two-liners with one action. The reading-speed hints are a nice touch.
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.
Imported an old SRT that drifted badly. Retimed the whole thing in one evening, in a browser.
Every SRT I’ve exported has uploaded to YouTube and Vimeo without a single validation error.
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.
Burning in (or hardcoding) draws the subtitles onto the video frames, so they’re part of the picture and show on every player. A separate SRT or VTT file, by contrast, can be switched on and off.
Yes for the first 90 seconds of a video, with a small BlaBlaScribe watermark — no account needed. Paid plans export the full video without the watermark.
No. The video and the subtitle file are read and rendered in your browser; neither is sent to our servers.
The MP4 keeps your video’s original resolution and aspect ratio. It’s re-encoded as H.264 with your audio, as any burn-in has to be.
Common video formats such as MP4, MOV and WEBM, with SRT or VTT subtitles. You need an up-to-date Chrome, Edge or Safari.
Yes: ffmpeg -i video.mp4 -vf subtitles=subs.srt output.mp4 burns an SRT in with the default look. This tool does the same in the browser, with styles and a preview.
