Green Screen 
Preparation Guide

What does it do? 
. The Green Screen process makes a 
selected range of color become transparent 
to reveal an image underneath. 
. Allows subject to be placed in front of any 
background. 
. Before coming in to use the Green Screen, 
think about what images you would like to 
use.

Backgrounds 
. Any Image or video can be used as a 
background. 
. A library of backgrounds to use is available 
to look through, but feel free to provide your 
own. 
. Make sure your material is not copyrighted. 
* Background images should be at least 
1280x720 pixels in size. 

Background Examples 

Titles 
. Titles can be added to your video to 
supplement what you are saying. 
. Think about what your main points will be 
and which of them you may want to appear 
on screen. 

Script Writing 
. Writing a script of what you plan to say on 
camera allows you to stay on point. 
. Try to write as though you are having a 
conversation to avoid sounding stiff. 
. If possible, send scripts in a plain text format 
(.txt) 
. The script can be loaded onto a teleprompter 
for you to read from. 

Final Notes 
. Use the video request form on the CTL web 
page to request a video. 
. Keep in mind that green screen videos can 
take a few weeks to complete.
