Animated previews in Wowza Video help viewers quickly assess content by providing a short clip that showcases a key scene or a highlight when the viewer hovers over the video screen or a thumbnail of the video. This enhances user engagement and decision-making by supplying a visual snapshot of the content before a user commits to watching the video.
The preview clip is generated as a looped WebP image and an MP4 video file that don't contain audio. They're generated by taking a 5-second video sample starting from the position the user selects on the Preview player.
The WebP file, by default, is used with the player. More information about the WebP format can be found here.The URLs and downloadable files for the animated previews display in the Manage Files page under the Animated Preview Files list.
Your video may already have an animated preview clip if you have Automatically Generate Animated Previews on Video Uploads checked in Org Settings. The platform autoselects the part of the video to animate.
Review the Video Details page UI reference article for animated preview configuration options and definitions.
