This application provides a video processing method and a related electronic device. The video processing method includes: When generating a video, the electronic device may perform image zooming based on a change in a zoom ratio, or may perform audio zooming on an audio based on a change in a zoom ratio. That the electronic device performs audio zooming on the audio includes: When the zoom ratio increases and an angle of view decreases, suppressing a sound of an object outside a photographing range and enhancing a sound of a photographed object within the photographing range; when the zoom ratio decreases and the angle of view increases, suppressing a sound of an object outside the photographing range and weakening a sound of a photographed object within the photographing range.
