Abstract: Embodiments of this application disclose a video switching method and a related device, and are applied to the multimedia field. The method in embodiments of this application includes: A video transmit end receives a video switching instruction when sending a first video frame, where the first video frame is one frame of video data of a first video stream that is being sent by the video transmit end; and the video transmit end switches video data in response to the video switching instruction when a first field blanking period after the first video frame arrives. In embodiments of this application, a video data switching process of the video transmit end may be controlled to occur in the field blanking period, and the video transmit end always sends a complete video frame to a video receive end.
