The method of distance education course recording is changing with the development of information technology.

2009 ago, most of the use of the three-point screen, the teacher in the upper left corner of a very small video, right is the location of the courseware. This is due to the video server and network bandwidth limitations, and video files can not be done very large, so the teacher's video, courseware and Directory menu separation, and the use of different technology storage and playback synchronization. Commonly used is the powercreator.


But as the browser continues to upgrade the compatibility issues, as well as the 64-bit system control loading problems, Powercreator gradually quit the market.

At the same time, the application of recording screen software is also developing, such as "screen video expert", CamStudio and so on. Computer-related educational field recording screen software is more, wherein Camtasia Studio can realize the interactivity of courseware. such as "North Wind Net", "Preach Wisdom Podcast", the flaw of recording screen software is unable to see the teacher's picture.

With the development of broadband technology, cloud computing, cloud storage technology, all school schools have adopted a large-screen video teaching method, such as the positive education, global education, you can log on to the above website, listen to the course can understand the effect of video courseware.

The key point of their recording scheme is the big screen, VCR, recording studio, etc., the investment is bigger. Overall procurement decoration scheme a recording shed (including hardware software and decoration) estimated to need 200,000, and because of the reflection and recording exposure changes in the reason, the basic use of black, PPT of the effect of the basic performance. Human resources and costs are high, and production efficiency is not high.


The big screen is basically procured in Shang (www.go2school.cn). With the development of liquid crystal technology, the large screen now uses large LCD screen.


I am also a family of textual research, several large school classes have studied, and gradually feel this kind of video learning effect is not good, a great show feeling. And because the author has personally carried out this mode of recording, equipment investment high, operation and maintenance costs, low production efficiency. The author has been looking for a better solution.

In 2006, there appeared a forum for sharing examination Study Materials Forum (www.topsge.com), quickly aroused the attention of the vast number of textual research, in 2012, its fine courses online "School Network" formally on-line, its unique video recording method also let my eyes a bright.

This solution does not need to purchase a large screen, just the video signal of the recording screen and the teacher's video signal can be synthesized.

The teacher behind the use of background cloth, record the video signal by the way of keyed drawing. To achieve this effect, the author consulted the relevant suppliers of video collection and compilation of hardware and software costs, at least 60,000 yuan. Then there is no more convenient and inexpensive way.
