3. Reference_JavaScript_2.5.pdf . A handbook to understand the usage of JavaScripts in MXWendler. There are many examples that can be pasted and tried in the software in order to understand how to take advantage of JavaScript in your video-workflow.

4. WalkingMan_Outline_Loop_.avi. A sample clip to demonstrate the effect of the scripts.
