How to Export Small Alpha Videos from After Effects

In this tutorial am going to take you through some of the easiest ways to render a small workable transparent or alpha video: That u can use in your projects in Adobe after effects and some other video editing Adobe Premiere Pro or Camtasia projects.
The goal of this to show how I managed to export small size alpha videos, am saying small because usually when you try to export alpha + RGB videos(lower thirds, Logo Animations Buttons, etc.) in After effects they come out with a very big size usually at around 2GB plus of which that size is so inconveniencing to work with.
