Wowza Video provides the ability to generate an animated preview clip that will display whenever a user hovers over the video. The preview clip is a looped WebP image file that doesn't contain audio. It's generated by taking a 5-second video sample starting from the position selected by the user.

Your video may already have an animated preview clip on your video, if you have Automatically Generate Animated Previews on Video Uploads checked in Org Settings. The platform autoselects the part of the video to animate.

More information about the WebP format can be found here.

Review the Video Details page UI reference article for animated preview configuration options and definitions.
