Based on the characteristics of a reel-spinning video, a video encoder/decoder can rely on image date from a preceding video frame to reconstruct a current area of a current frame of the reel-spinning video. The video encoder can record some indication of the current area (e.g., number of dropped blocks or boundary values of the area). The video encoder can rely on motion information (e.g., a motion vector) of a preceding area within the current frame, or encode motion information with the indication of the current area. The video encoder then transmits the indication of the current area, perhaps with a subsequent area, without image data of the current area. The video decoder can then reconstruct the current area with image data from a matching area in the preceding frame based on the motion information.
