Create a captioned video

Upload a clip, pick one of 26 caption styles, adjust it and render an MP4.

Updated October 2, 2026

  1. Open My videos in your dashboard and upload a clip (MP4, MOV, WebM or MKV).
  2. BriefVox transcribes it and times every word. The clip then opens in Captions Studio.
  3. Pick one of 26 ready-made caption styles, then adjust the font, colours, animation, size, line width and position. You can drag the captions anywhere in the frame.
  4. Choose the format: 9:16 (TikTok, Reels, Shorts), 1:1 or 16:9. BriefVox suggests one based on your clip.
  5. Render. When the video is ready, download it.

What is charged

Minutes are charged once, when the clip is prepared. Fixing the text and rendering the same clip again is not charged again.
