Abstract
Generating animated seek previews for panoramic videos is described. In one or more implementations, a video frame associated with a seek point of a panoramic video is received. The video frame is reverse projected to generate a 3D projection. Portions of the 3D projection are then formed that are centered on and span an equatorial axis, and each portion is projected to a 2D plane to generate 2D projections of the portions. Animation frames are generated based on the projected portions, and the animation frames are compiled into an animation for consumption by a user as an animated seek preview of the video frame corresponding to the seek point.
