Hey videofreaks
Recently I had the opportunity to check out some of the beautiful projects here on Videohive, people do amazing things with layers in motion 
Im wondering why many people use layers (Null objects) for control cameras in After Effects. Why not use the timeline of the camera?
Just curious…. thanks!
