Video EFX Lightning Filter property page

The Video EFX Lightning Filter 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.

Threshold slider

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

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.
