• receiving, by the electronic device, a first operation by a user on the first screen at the second moment;
• displaying, by the electronic device, a second screen in response to the first operation, wherein the second screen is a viewfinder screen of the electronic device recording video from the second moment to a third moment, the second screen comprises a third preview image captured by the first camera and a fourth preview image captured by the second camera, the second screen further comprises a second preset control and a second icon, and the second icon is used to indicate that the electronic device is to play a recorded video from the second moment to the third moment at a second speed, the second speed is different from the first speed;
• receiving, by the electronic device, a second operation of the second preset control by the user at the third moment;
• displaying, by the electronic device, a third screen in response to the second operation, wherein the third screen is a viewfinder screen of the electronic device recording video from the third moment to a fourth moment, the third screen comprises the first icon, a fifth preview image captured by the first camera and a sixth preview image captured by the second camera;
• receiving, by the electronic device, a third operation by the user, wherein the third operation is used to trigger the electronic device to terminate video recording;
• generating, by the electronic device, a first video file in response to the third operation, wherein the first video file comprises:
• a first video stream and a second video stream corresponding to the first moment to the second moment, a third video stream and a fourth video stream corresponding to the second moment to the third moment, a fifth video stream and a sixth video stream corresponding to the third time to the fourth time, the first video stream comprises a plurality of frames of the first preview images, the second video stream comprises a plurality of frames of the second preview images, the third video stream comprises a plurality of frames of the third preview images, the fourth video stream comprises a plurality of frames of the fourth preview images, the fifth video stream comprises a plurality of frames of the fifth preview images, the sixth video stream comprises a plurality of frames of the sixth preview images;
• receiving, by the electronic device, a fourth operation by the user, wherein the fourth operation is used to trigger the electronic device to play the first video file;
• and
• playing, by the electronic device in response to the fourth operation, the first video stream and the second video stream at the first speed, playing the third video stream and the fourth video stream at the second speed, and playing the fifth video stream and the sixth video stream at the first speed.
