What's the Difference between using Null Object to move something with a Key frame or using the camera for that.
when is recommend to use null object rather then the camera and Vice versa ?
Nulls are easier to control because their actions are more predictable. They tried, but AE's camera controls are just flippin' weird. You can gang nulls together for position, pan & tilt to make a rig that works like a real-world camera.
