Object to make Perspective View follow objects

This model has an object called ViewControl that you can use to make perspective views follow differen objects in the model. When you open the model you will see that there are 5 labels that you can change and they are as follows:

Object - Set this label to the rank of the object that you want the view to focus on
Distance - This is the x/y distance you want to stay away from the object you are following
Height - This is the height above the object that you want to view the object from
Follow - This is a 1 or 0 field. 1 will cause the view to follow the object from behind and 0 allows you to specify the z rotation yourself
SV - This is a 1 or 0 field. 1 will insure that the only view to change will be the sv view and 0 will make all perspectiveviews follow the object.

Have Fun,

How can I capture video using the above code? What should be the sv() designation?

Thanks a lot for the code.
