description A video processing method and an electronic device are provided. In a zoom photographing scenario, a sound propagation latency caused when a sound is transmitted from a sound source to the electronic device and an algorithm processing latency of the electronic device affect accuracy of an audio timestamp corresponding to audio, and cause audio and image asynchronization. In this application, a first audio timestamp of first audio is corrected based on a first latency corresponding to the first audio, to correct a correspondence between the first audio timestamp, the first audio, and a first image. In this way, a stored correspondence between the first image and the first audio is consistent with a correspondence between a picture corresponding to the first image and a sound corresponding to the first audio, thereby implementing audio and image synchronization.
