The Lens Video effect adds a fish-eye-like filter to the video by magnifying an area of the video. The property page is shown in the figure below:
The Lens property page provides a user interface 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 to abandon changes by selecting Cancel.
