An example method includes obtaining a first video and a second video, where the first video and the second video have same content, and image quality of the first video is lower than image quality of the second video. M first video frames and identifier information of N target frames based on the first video are obtained. Related frames corresponding to the N target frames are obtained from the second video based on the identifier information of the N target frames, where the target frames and the related frames have same identifier information but different image quality.
