Green screen for video is a popular and cost effective visual effect that allows you to tell your story in front of any background. Before electronic chroma keying, compositing was done on (chemical) film. Watch the video above and see if you realized those scenes were done using chroma key. Before we learn how to edit green screen footage, let's look a little deeper into what green screen footage is, and why we use it.

The benefits of shooting against a green screen are numerous, allowing for flexibility in handling more than one location, the quick and efficient set up and take down of a set, and maximum control when it comes to branding.

However, if you're going to be shooting in only one dedicated location, I'd suggest you use green-screen paint. Most film editing programs like Final Cut and Adobe After Effects will make it simple to remove and replace the background from chroma keyed footage.

Today, many movies and television shows are filmed entirely in front of a green screen, allowing the filmmaker tremendous artistic control while cutting down filming times and production costs. Join host, Larry Jordan, as he illustrates a variety of production techniques to create green screen footage, then creates finished effects using Apple Final Cut Pro X and Adobe Premiere Pro CC.

When using a digital camera instead of film, you obtain better results from a green screen shoot because of the cleanness and luminescence of green over blue. You want the background light to be as even as possible over an evenly-colored green background. So, for instance, a car will be filmed against a green background and then any type of road scene or suitable environment will be used to replace the green using Chroma Key technology.

It's easy in the chaos of planning a shoot to overlook these basic steps when heading in to a green screen shoot. Green screen is a video production technique that you may be familiar with as it's used in many Hollywood movies. Working with a green screen presents a series of unique challenges, both in production and in post.

This gives a bit more definition from the background but isn't necessarily good for compositing into a background scene where you need to match lighting. This process is just as important when lighting for your green screen. Luminance keying, or lumakeying, is the process of keying out a brightness value or range, like black or white.

You will also need a good quality Chroma key software, many are available on the market and some can even be downloaded for free. Worse, even if you do allow enough distance between subject and background, shiny surfaces like shoes, buttons and eyeglasses can still reflect that green background—and that ain't good.

This may seem like an easy step, but failing to clear the green sheet of wrinkles may cause a fair amount of trouble in the post-production Make sure that the piece of sheet you are using as your background is perfectly smooth because even the tiniest wrinkle will be visible once you remove the background in a video editing software.

Lighting your subject separately from your green screen is going to make the chroma keying process much simpler and more effective because it's extremely difficult to pull a key from a poorly lit green screen. Rich: Absolutely, and I think the main thing here to take away is that I've seen people try to do keying like luma keys for video or we'll shoot on a dark background, we'll knock that out.

For the more technically inclined: Chroma Key Green" is approximately valued at 354C in the Pantone color Matching System.1 There are other versions of the color out there that may work, but it would be advisable to stay as close to 354C as you can. If the subject isn't lit correctly or the green screen is too dark, too bright, or uneven, chances are you'll have problems pulling a good matte.

Blue and green are on the opposite end of the color spectrum from red and orange, the main colors in skin tones. The lighting of the green space also needs to be as even as possible across all surfaces in order that the chroma key filter can accurately register and remove all the green color from the image, without any patches remaining.
