LEAD Video EFX Motion Emboss Filter User Interface

The Motion Emboss Video effect gives moving objects an embossed or raised. The property page is shown in the figure below:

The Motion Emboss 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.
Light Angle slider	The direction of the light, in degrees. Range: 0 to 360 degrees.
Elevation slider	Elevation angle. Range of values is from 0 to 180 degrees, where 0 will cause outer embossing, and 180 will cause inner embossing.
Depth slider	Depth of the emboss effect. Range: 1 to 100.
Threshold slider	Value used to control an object's detection level. A lower threshold provides stronger object detection. Range: 1 to 100.
Emboss radio button	If selected, emboss without a bump map.
Bumpmap radio button	If selected, emboss with a bump map.
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 after the stream starts will have no effect.
Set current frame as reference button	Sets the current frame as the reference frame.
No reference frame check box	Controls the reference frame. If this is selected, the reference frame is assumed to be a black buffer. If it is cleared, the reference frame will be the frame set using the Set current frame as reference button.
