Where is my video processed?

Everything happens in your browser: transcribing, editing and burning the captions. Your video is never uploaded to Drefly's servers.

Will the burned video look exactly like the preview?

Yes. The editor draws the preview with the same caption renderer that burns the final video, at the video's real resolution, so the font, size, colors, box, position and animation come out exactly as you saw them.

Can I fix mistakes in the transcript?

Yes. Edit any word in the AI panel after transcribing, or in the Captions tab inside the editor. Changes show on the video right away.

What can I change about the captions?

Font, size, bold, italic and all caps, text and highlight colors, outline and shadow, a background box with its color, opacity, padding and corners, words per line, lines on screen, width and spacing, position anywhere on the frame by dragging, and how words appear: one by one, all at once with the current word highlighted, or all at once.

Which languages work?

Transcription supports close to a hundred languages, including right-to-left scripts like Arabic and Urdu, which are laid out right to left in the captions too.

What formats can I download?

MP4, WEBM or MOV, at the original resolution or scaled to 1080p, 720p or 480p.

Is Burn Captions free?

Yes. It's free with no signup, no watermark and no limit on how many videos you caption.
