User Interface
The Brightness filter 'hides' moving objects. In places where there is movement, the brightness of the background changes allowing you to see that there is movement, but you can only guess what it is by the shape. The property page is shown in the figure below:
Use the Brightness property page to change the filter's attributes. Changes will be applied directly to the streaming media with the ability to set them permanently by selecting Apply or OK, or abandoning them by selecting Cancel. To display general information about a control, position the mouse pointer over it. The following table shows the controls and their descriptions:
