Whew! After a couple of hours of searching, I finally figured out how to add my Camtasia 6 output to my Wordpress blog.

1. Download and install the Kimili plugin.
2. Add the [ kml_flashembed movie="/path/to/video/video-file_controller.swf" height="250" width="400" fvars="csConfigFile=/path/to/video/video-file_config.xml" / ] to my post or page.
   Note: What I couldn’t understand was that you don’t call the myfile.mp4 file but the controller.swf file. This will embed your video and the controller.
