Three-point lighting will help your scene look more realistic and cinematic. You can add blur, shadow, lighting, and other effects back into the scene in post-production. If someone is waving their hand or there’s a lot of hair blowing in the wind, a higher shutter speed will give you a cleaner key. Raise your shutter speed to 1/80 or 1/100 to help reduce motion blur. This can be very tricky and require more advanced techniques like camera tracking.

Any camera movement in the shot will need to be replicated when replacing the green screen. Use a tripod to ensure your camera is as still as possible. We recommend keeping your green screen scenes stationary when starting out. There’s nothing worse than giving your actors a haircut in post. Blonde hair, for example, tends to reflect green screen light, giving you a sloppy chroma key. Before filming, check for light spilling off the green screen onto your talent. Whatever lights you choose, make sure they are soft and large so they offer smooth, even lighting that covers the entire green screen. The important thing is making sure to light your subject and screen with different lights. Ideally, you’ll have more lights so you have options for lighting your subject. The other light will be for your subject. Two will be dedicated to keeping your green screen evenly lit. Generally, you’ll want to use at least three lights. This includes anything reflective your subject might be wearing. Be sure to remove all shadows and, if possible, remove anything reflective in the room that could compromise the lighting in unexpected ways. Aside from lighting your subject, be sure your green screen is evenly lit so you end up with an effortless chroma key. Some of that can be adjusted in post, but the more work you do in advance, the less time you’ll spend in front of the computer. Imagine a changing stoplight or a dim nightclub scene with flashing lights, but your subject is lit like they’re in the grocery store with bright fluorescent lights. If the lighting will be overhead or from the side, use the same angle when filming. Whatever lighting you use, it needs to make sense for the scene you’re shooting once the layers are added.

The point is to use a color that your editing software will be able to clearly identify and is starkly different from any other object in your scene. Setting up your green screenĪ green-colored screen is the most common, but you can also use a blue or purple screen. Going into post-production with a sloppy key that could have been avoided isn’t pretty and will be difficult if not impossible to fix. You don’t want to have to try and fix things like poor lighting and strange shadows in post. There are a few considerations to help you make sure you get the best possible shot. We’ll go over how to build your set, set up your lighting, and how to edit to consistently great results. If you want to create a perfect image composite with green screen and chroma key, this guide will show you how to avoid common mistakes and have a process for getting the optimal footage for your edit. You want a clean key, meaning the entire green screen is removed without blurry edges or leftover color that can ruin the realism you are attempting in the scene. When you are keying your scene, you’re removing the green screen background to add your layers. Along with a green screen, chroma key is the process used to remove the particular color (typically green) and replace it with another color, image, or video. It’s most commonly used to composite multiple images together to do things like replace a background, blend two different scenes together, or create surreal special effects. Just in case you weren’t sure, a green screen is a brightly colored backdrop used for removing objects from a scene when you edit. One of the biggest frustrations for newbie green screen film-makers is getting seamless, natural-looking chroma key results. Even with the advancing technology that makes creating this effect more accessible, using green screens can still have its pitfalls. With a relatively small investment, green screens are a do-it-yourself set-up that can provide Hollywood-quality results.
