This is a camera rig set up I was playing around with in Cinema 4D that mimics how a film or TV camera would work. Certain camera moves are compartmentalized and set up in ways to help get more cinematic camera moves more easily. It's a pretty good setup to help you think of the camera as a real object in your scene and helps you avoid floaty 3D camera moves.
.Features like camera shake or constraining it to a track are built into the control's User Data, making them easy to use and turn off or on.
.You can swap in your own spline for the rig to follow and the controls will work the same.
.The rig is scaleable in case your scene isn't built to real world scale and the height display will still give you the relative height of the camera off the base of the rig.
And it's only 5 bucks. Come on, you know you've got 5 bucks laying around.
