LEAD Video EFX Motion Scan FilterUser Interface

The Motion Scan Video filter scans one line per frame and draws it to the destination, giving the frame a "radar" appearance and distorting the moving objects. The property page is shown in the following figure:

The Motion Scan 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.
