LEAD Video EFX Brightness Filter 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:



Enable check box

Enables/Disables the effect.

First frame as reference check box

Enables or disables setting the first frame in every play session as the reference frame. If this is selected, the first frame in every play session will be set as the reference frame (Usually the first frame in a movie).
If this is cleared, then the reference frame should be set manually after a number of frames. Setting this property after the stream starts will have no effect.

Set current frame as reference button

Sets the current frame as the reference frame.

Threshold slider

Value used to control an object's detection level. A lower threshold provides stronger object detection. Range: 1 to 100.
