Captions for YouTube

Captions for YouTube videos.

Captuno captions widescreen videos as well as vertical ones: captions burned in low in the frame, and an .srt file with the same timing for YouTube's own subtitles.

Where captions go in a widescreen video

In a 16:9 video, Captuno sets the captions low in the frame, within the middle 70% of the width. When there is already text at the bottom of the shot, like a name title or a slide, they move up out of its way.

Burned in, and an .srt file

You get both: the video with the captions burned in, and an .srt file with the same timing. Add the .srt in YouTube Studio as a subtitle track so viewers can switch captions on in the player, and use the burned-in video for clips and anywhere the player's captions don't show.

Captuno takes videos up to 15 minutes long: enough for most tutorials, reviews and vlogs, though not for streams or full-length films.

How to caption a YouTube video

  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.

Styles that suit widescreen video

  • plain: White text with a dark outline.
  • underline: A coloured line runs under the spoken word.
  • minimal: Small light text on a soft dark bar.
  • documentary: Small spaced capitals with a thin line above.
