摘要： This application relates to a computer vision technology in the field of artificial intelligence. A video shooting method includes: enabling a camera application on a terminal (for example, a mobile phone); and in a slow-motion video recording mode of the camera application, when a motion detection function of the camera application is enabled: starting to capture video frames after a video recording instruction input by a user is detected; recording a second video frame set at a first frame rate automatically when a motion of a human body in a captured first video frame set is a preset motion; and generating a target video, wherein the target video includes a slow-motion video clip, and the slow-motion video clip includes some video frames in the second video frame set. When the motion of the human body is a first preset motion, duration for playback of the slow-motion video clip at a first playback speed is first duration; when the motion of the human body is a second preset motion, the duration for playback of the slow-motion video clip at the first playback speed is second duration; the first preset motion is different from the second preset motion; and the first duration is different from the second duration.
