Camera stabilizer

Someone knows how to make camera stabilizer like in this video camera stabilization 02 - YouTube?

Many ways of doing this.

One way is to simply isolate the camera off the character, and use a smooth follow script from standard assets to follow a game object that represents the desired camera pos and rot.

One is to have the camera has two Vector3s for rotation one for previous rot, one for desired rot. Take a float value to determine how much you will compensate for the rotation.

@Kaiser_V For some reason, when I click the RMB, the eye does not appear, but instead the hand tool does. I have tried alt and mouse scroll, but it is still the hand. This is very frustrating because I had a project I put a lot of time into, but now I may just have to make a new one. Any help?
