 * Hello,
 * I want to optimize a video, but I don’t understand what to do to add subtitles
   to my video. Which software to use?

 * [@compas972](https://wordpress.org/support/users/compas972/) Thank you for opening
   your topic! When selecting a video, the “[Upload captions](https://jmp.sh/7XNVwlZ)”
   field will display in the Design panel. There you can select a file from your
   local files to upload. The required captions format is WebVTT (.vtt) which you
   can learn more about [here](https://developer.mozilla.org/en-US/docs/Web/API/WebVTT_API).
