Vibrate Expression
This expression can be used ( Regular Pulse option) to cyclically change the size, position and rotation of objects.
On the other hand ( Random option), you can add random behavior to the animation. For example, if you are simulating a tracking shot in a car driving over rough terrain, it will look more realistic if the camera randomly moves up and down to simulate the shaking - just as if it were being shaken by the ride.
Incidentally, this expression can be used for all object types - from basic objects to deformation objects, etc.
Example
In the following example, the camera has received a Vibrate Tag that affects the position and orientation of the camera. This creates small camera movements that give the impression of a camera being held in the hand. To ensure that the animation always begins with the same start state, the Vibrate Tag is only activated in frame 1 (the camera has keys for position and rotation in frame 0).
