If some parts of the resources are more suited to be showed by the form of illustration instead of video, the animation is needed. In general the software Macromedia Flash from Adobe Company is intuitive and versatile for editing. Other software of courseware production such as AuthorWare can also be considered. Before the content of demo is edited, clear description and detailed text should be given in order to ensure the process logically. In addition, when each form of video has been finished, size optimization should also be considered so that the readers can watch or download resources on the internet smoothly.
