OpenCaptions

Green screen captions for your video editor

Sometimes the captions should be a layer, not part of the video. OpenCaptions can save only the captions, animated, over solid chroma green and with no sound. Key the green out in your editor and lay them over any footage.

How

Section titled “How”
  1. Transcribe your video and style the captions as usual.
  2. Choose Green screen as the background when you save. On the web, use ProRes or H.264.
  3. In your editor, put the file above your footage and key the green out.

The result has the same timing and the same animation as the preview, because one engine draws both.

Questions

Section titled “Questions”

Why not subtitle files? SRT and VTT carry the words and their timing, not the look. OpenCaptions exports those too, for when a plain subtitle track is what you want.

Does it work on the iPhone? Yes. In the app the choice is in the Save sheet, under Background.
