LEAD Video EFX Ghost Filter

User Interface

The Ghost Video filter makes moving objects invisible. The property page is shown in the figure below:

The Ghost property page provides a user interface for changing 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 to abandon changes by selecting Cancel. Positioning the mouse pointer over a control displays general information for that control. The following table shows the controls and their descriptions:

Control	Description
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.
