A method for processing motion video shooting, comprising: shooting a subject in a background sample, the background sample and a target background, generating a first video file recording the subject plus the background sample, a second video file recording the background sample and a third video file recording the target background respectively, wherein shooting durations of the first video file and the second video file are less than a shooting duration of the third video file; and comparing the first video file with the second video file, extracting a subject image from the first video file to generate a subject image frame sequence of which a background is transparent, and superimposing in turn each frame subject image in the subject image frame sequence onto the third video file to generate a motion video file recording the subject and the target background, wherein: shooting a subject in a background sample, the background sample and a target background, generating a first video file recording the subject plus the background sample, a second video file recording the background sample and a third video file recording the target background respectively comprises: shooting the subject in the background sample at a first shooting sample rate after an instruction for shooting the subject is received, and generating the first video file after an instruction for stopping the shooting is received; shooting the background sample at a first shooting sample rate after an instruction for shooting the background sample is received, and generating the second video file after an instruction for stopping the shooting is received; and shooting the target background at a second shooting sample rate after an instruction for shooting the target background is received, and generating the third video file after an instruction for stopping the shooting is received, wherein the first shooting sample rate is greater than the second shooting sample rate. shooting a subject in a background sample, the background sample and a target background, generating a first video file recording the subject plus the background sample, a second video file recording the background sample and a third video file recording the target background respectively, wherein shooting durations of the first video file and the second video file are less than a shooting duration of the third video file; and comparing the first video file with the second video file, extracting a subject image from the first video file to generate a subject image frame sequence of which a background is transparent, and superimposing in turn each frame subject image in the subject image frame sequence onto the third video file to generate a motion video file recording the subject and the target background, wherein: shooting a subject in a background sample, the background sample and a target background, generating a first video file recording the subject plus the background sample, a second video file recording the background sample and a third video file recording the target background respectively comprises: shooting the subject in the background sample at a first shooting sample rate after an instruction for shooting the subject is received, and generating the first video file after an instruction for stopping the shooting is received; shooting the background sample at a first shooting sample rate after an instruction for shooting the background sample is received, and generating the second video file after an instruction for stopping the shooting is received; and shooting the target background at a second shooting sample rate after an instruction for shooting the target background is received, and generating the third video file after an instruction for stopping the shooting is received, wherein the first shooting sample rate is greater than the second shooting sample rate. shooting the subject in the background sample at a first shooting sample rate after an instruction for shooting the subject is received, and generating the first video file after an instruction for stopping the shooting is received; shooting the background sample at a first shooting sample rate after an instruction for shooting the background sample is received, and generating the second video file after an instruction for stopping the shooting is received; and shooting the target background at a second shooting sample rate after an instruction for shooting the target background is received, and generating the third video file after an instruction for stopping the shooting is received, wherein the first shooting sample rate is greater than the second shooting sample rate.
