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 .
