Abstract
Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for synchronizing recorded videos. The methods, systems, and apparatus include actions of receiving a first video and a second video, determining first time stamps from pixels in the first video, determining second time stamps from pixels in the second video, determining an earliest frame in each of the videos that time stamps match, pairing the earliest frames, determining that a subsequent frame in each of the videos have corresponding time stamps that have a difference that satisfies a criteria, and pairing the subsequent frame in the first video with a frame after the subsequent frame in the second video.
