Abstract

The invention provides a video shooting method and system used for adding background music to a shot video during video shooting. The method comprises the steps of firstly playing the background music in the background to obtain decoded audio data of the background music, then performing channel conversion and re-sampling of the audio data to obtain audio data which meets the video shooting requirements in term of the number of sound channels and the sampling rate, and finally performing audio and video synchronization of the shot video and the audio data meeting the video shooting requirements and performing encoding to obtain a video file with the background music. By applying the video shooting method and the system, the background music can be added to the shot video while videos are shot, and noise is ensured not to exist in the background music.
