Change Seasons in Your Video with Green Screen Technique

Filming or shooting your subject in front of a green or blue screen allows you place various backgrounds behind them. You even can make a summer video in the middle of the winter or make an autumn scene in the early spring. In this lesson, I will show you how to do this with minimal resources.

Step 1: Things You Need

Green Screen Studio
Setting up this kind of studio is not as complicated as you might think. You just need a place with a wall colored in green. There are three types of chroma key background materials that you can use: fabric, painted, and paper. Unless you are a professional film maker, I would recommend the last one for a home studio as it is cheap and easy to set up on a wall. Remember that brighter is better, so go for a more neon or lime green color when choosing material. 

Also you should plan your screen lights. The key to lighting a green screen is consistency. The whole point is to create a single, consistent shade of color across the entire screen.

Video Footage
With your video background you also have a choice: You can invest your time in making your own or buy the professional, but quite expensive, footage on stock sites. I prefer making video background in DP Animation Maker. It’s easy; you get awesome results for many purposes; and it’s priced reasonably.

Video Editor
You can use any program that supports the Chroma Key feature. I used Wax, the simple freeware video editor.

Step 2: Filming Chroma Key Video

As soon as you have everything ready, the first thing you need to do is film the foreground green screen footage. I made a short movie starring my daughter.

Step 3: Creating Video Background

The second thing is background video for your film. In DP Animation Maker, I started with an autumn photo and then added falling oak and maple leaves as well as blinking rays of light. The result was saved in AVI format with Xvid codec.
