About
The Thumbnails module enables users to customize and manage thumbnails for their videos. By default, Kaltura generates a thumbnail at the three-second mark, but with the thumbnail settings, users can set, adjust, and refine thumbnails to best suit their content. Once the Thumbnails module is enabled, a Thumbnails tab will appear on the video’s Edit page.
