Abstract
This application disclosed video transmission methods and devices. 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. The M first video frames and the N related frames are recorded to obtain a third video, where the third video is transmitted to a receiving device, and a data volume of the third video is less than a data volume of the second video.
