Common questions
What are the free limits?
Up to 25 MB / ~90 seconds per video, three per hour, with a small watermark. Signed in, captioning is full-length and watermark-free.
How accurate are the captions?
The video is transcribed automatically and captions are timed to the speech. You pick the style (Bold, Neon, Clean) and position so they never cover the wrong part of the frame.
Does it work with any aspect ratio?
Yes — your video comes back at its own size and shape, uncut. Only the captions are added.
