After the form of multimedia resources is determined, the drafting of content should be written out and the video script should be edited. In the editing process, camera lens should match with the relative content of the course. The appropriate selection of places which background music is inserted into should also be considered. A lot of details are included, and patience should be paid. All the work should be prepared for a long time. In order to prepare each module fully, the scene and lens according to the relative content should be shot at the beginning. If some important passages which are suddenly remembered need to be inserted into one part of the films, the unity and coherence of the films will be affected.
