Drafting and planning - CCTV overlay

I have said that i will be including a CCTV overlay to my music video and i am currently adding that in the editing process. This is a technique that i haven't done before so in order for me to do this i have to first research how to. I am using the software Movie Plus X6 which has a help tutorial page within it on how to add something over a footage clip.

Here is the screen shot of the relevant section on how to add the effect and from what i have read it is not a hard process to do. I can easily create a png image of a cctv recording camera and add it over the the footage. 

By researching how to do this it can help my editing process as i can continue editing.
