If you produced your Camtasia Studio video using the Flash ExpressShow feature, it may be the case that you cannot see the player controls beneath the video.

The reason for this is the Camtasia include some extra CSS in the HTML page to make the video appear in the center of the screen, with a black background. This CSS code causes problems when trying to embed the video, and needs to be removed beforehand.

If you open the HTML page using either Notepad, or a similar HTML editor, you can simply select and delete the code highlighted in the image below:

This will allow the video to be embedded correctly into the page.
