Hi,

Could you please specify what kind of special effects you are interested in?
For example, if you want the talent (billboard) to appear or disappear with stylish transitions, there is a useful discussion here about adding a dissolve-like effect: https://my.aximmetry.com/post/2406-can-the-host-be-added-with-an-entrance-o 
Note, Aximmetry’s library contains many other similar effects that you can choose from, allowing for a variety of creative entrance and exit animations.

Warmest regards,
