A Thumbnail is a small image captured from the video in order to recognize the video when embedded and not playing. Initially the thumbnail is chosen automatically by the system based on a random frame from the video.

Upload Thumbnail

  • Upload a image and set it as thumbnail.


  • Choose a specific frame from the video and create a still as thumbnail.


  • Choose one still generated randomly and set it as new thumbnail.

NB: This option is not available for YouTube video’s!
