What makes a good caption generator

Accurate word timing, clean sentence segmentation, and language coverage beyond English are the three things that make auto-captions actually usable instead of a rough draft you have to redo.

⏱️

Word-level timing

Captions are timed per word, not just per sentence, for tighter sync and easier manual tweaks.

✂️

Clip-boundary aware

Segments respect cuts and gaps in your timeline instead of running captions across edit points.

🌐

99 languages

The full range Whisper supports, not just the handful most caption tools focus on.

Captions vs a raw transcript

A transcript is one long block of text; captions are that same text broken into short, readable, correctly-timed chunks for display on screen. CaptionLab generates the caption-ready version directly — segmented SRT, not a wall of text you'd have to chop up yourself.

Frequently asked questions

Does it generate a plain transcript too, or only captions?
The output is a segmented SRT file — usable directly as captions, and easy to read as a transcript too since it's just timestamped text.
Can I control caption line length or reading speed?
Segmentation follows natural speech pauses and clip boundaries; there isn't a manual line-length control in the current version.
Does it support burned-in captions, or only SRT?
CaptionLab generates SRT files imported as an editable Premiere Pro caption track — burning them into the video is a normal Premiere Pro export step from there.
