optimize a video

@compas972 Thank you for opening your topic! When selecting a video, the “Upload captions” 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.

@compas972 We will mark this topic as resolved. Feel free to open a new support topic if you have any other questions. Thank you!
