(This is replaced by the Automatic Camerashake Script: https://www.cgtrader.com/free-3d-models/scripts-plugins/animation/automatic-vibrate-script-for-may)It can be frustrating to setup a camerashake in Maya for cameras. Every time you have to look up what expression you need and where to put it exactly. This is a 1-click solution.

Easy to use and does not require any type of installation, just run the script.
By running this script while having a camera selected it automatically creates a 'Camera Shake' attribute in the Attribute Editor, enables the camera shake option and puts an expression into the horizontal and vertical shake so that you can tweak it by increasing or decreasing the 'Camera Shake' attribute.

Tested in Maya 2015, 2016, 2017 and 2018.

Hope it helps! :)
