Claim 8:
9. The method according to claim 4, wherein the video file comprises image frames representing different time points, the preset factor comprises the system time of the terminal, and the mapping the value of the preset factor to the range [0, N] comprises:
performing normalization processing on a value of the system time according to the following formula to obtain normalized data:, Normalized
    ⁢
       
    data
   
   =
   
    
     System
     ⁢
        
     time
    
    
     C
     ⁢
     5
    
   
  
  ,
 

wherein C5 is a maximum value of the system time; and
mapping the value of the system time to [N3, N4] based on the normalized data, wherein N3 represents a sequence number of an onset frame, and N4 represents a sequence number of an end frame; and
the generating the one or more location parameters based on the result after the mapping comprises:
generating, based on [N3, N4], a location parameter that is in the video file and that is of each image frame from an N3th frame to an N4th frame.
