The invention provides an implementation method for storing and playing back multimedia objects, comprising the following steps of: step 10, creating a project, and creating a canvas window in the project; step 20, creating required multimedia object classes: namely object creation classes, object migration classes, object scaling classes, object rotation classes and object cancellation classes; step 30, storing corresponding data structures of the multimedia object classes respectively according to the time sequence of object operations; and step 40, when the multimedia files are required to be played back, creating a playback thread, reading the stored data one by one according to the time sequence, analyzing the data structures, and drawing by using a 2D drawing library of an operating system in the canvas window. The required multimedia object classes are created to store the corresponding class data structures according to the time sequence of object operations, and the thread is created to play back frame by frame according to the operation time, thus less space is occupied, and the occupation ratio of a CPU (central processing unit) is lower.
