Unity3D Tutorial - Fixing First Person View Camera Stutter/Jitter Issue

Hello everyone! This is my first tutorial on this channel. Here I made a tutorial on how to get smooth first person rotation in Unity3D. While making a first person view game you will notice mainly in the build game that when you rotate the camera the game stutters/jitters a lot which gets noticeable when circling around an object. In this tutorial I am showing one of a way to fix that. If my solution doesn't work then I have linked to other sources that fixes this issue using other means. You can find the links below.
