Captions for YouTube Shorts

Captions for YouTube Shorts.

Upload a vertical video (YouTube takes Shorts up to three minutes long), and Captuno burns in captions timed to every word, where the Shorts player won't cover them.

Where captions go on a Short

The Shorts player puts its like, comment and share buttons down the right edge, and the channel name, title and subscribe button along the bottom. Captions set where subtitles usually go end up underneath them.

In a 1080 × 1920 video, Captuno keeps every caption line left of x = 880 px, where the buttons begin, and sets the bottom of the captions around y = 1340 px, well above the bottom of the screen. If there is already text in the shot there, the captions move up out of its way.

How to caption a Short

  1. Export the video as an MP4 or MOV, up to 15 minutes and 2 GB.
  2. Open the uploader, drop the video in and pick a style. Each style is drawn on a moment from your own video before you choose. No account or credit card needed, just an email address.
  3. Captuno writes down what's said, times every word and renders the captions, then emails you a link. Watching the preview is free; the full-quality video and its .srt file cost $1.99 for every 3 minutes of video, or less with a pack of seconds.
  4. Upload the captioned video to YouTube as a Short.

Styles that suit Shorts

  • dynamic: Words land as you say them; the current one grows.
  • karaoke: The spoken word turns yellow.
  • bold: Condensed capitals, the spoken word in green.
  • punch: One giant serif keyword, and a gentle punch-in on the picture.
