One of the most obvious but still common green screen problems among amateurs is when part of the subject disappears into the background once the green screen is keyed out. This can be a mess to fix in post-production since you will have to rotoscope out all elements that left the green screen. Sometimes when an amateur is shooting in front of a green screen, the subject or part of their body may leave the green screen. Have the subject further away from the green screen, and the green screen also needs to be lit evenly across the screen.

One possible solution is to reduce the wattage of the lights closest to the screen, add additional lights further from the screen and backlight the subject while making sure they are not too close to the green screen. Resolving this problem again requires an understanding of production lighting. In fact, any object affected by this “green screen bounce” looks like it is surrounded by a green halo, which is not what you want at all. You get green fuzzy edges around your object, and the result is that your actor looks like they have a green reflection on their skin. Green Screen Color SpillĪ green screen color spill occurs when you have too much light on the green screen, something that might happen if you’re trying to eliminate shadows on a green screen. To avoid motion blur problems, shoot at a higher frame rate (like 120 frames per second) then in post-production interpret the footage at 30 frames per second, and speed up the clip 4 times. Shutter speed can help correct this problem. A motion blur problem occurs when your actor is moving so quickly it’s hard for the camera to pick up the motion against the green screen, and the fastest-moving objects tend to blend in with the screen. Motion Blurįor most corporate videos, this probably won’t be a problem, but if you do have any fast action in your video, you’ll need to watch out for motion blur. Properly lighting the green screen area is essential to the appearance of the final product. However, the easiest way to solve this problem is to prevent it from happening in the first place by using a green screen studio and video production company that is experienced in delivering high-quality green screen videos.

Professional video editors can use tools like Adobe After Effects to adjust the lighting. The Chroma key process allows video editors to remove a particular color from the image, but when there are different variations of the color because of uneven lighting, it can be more difficult to remove unwanted colors without also clipping away parts of the subject matter. With this common mistake, lighting may be very uneven, so there are unintentional dark and bright areas on the green screen. Try adding more lighting, reconfiguring your lighting, or moving the subject away from the green screen so they cast less of a shadow in order to eliminate shadows on the green screen. This is why professional lighting is so crucial during green screen filming. The only problem is that if your shadow is too strong, anything you do to try to eliminate it may also eliminate part of the subject that casts the shadow.

You don’t want the shadow to appear in your final product, so you will have to eliminate it in editing. Top Green Screen Mistakes Shadows on the Green ScreenĪ shadow on your green screen can create a real problem. Here are some of the top green screen mistakes and what you can do to avoid them. It sounds simple enough, but there are a number of green screen mistakes that can affect the quality of your video. You can rent a green screen production facility for this purpose, or purchase your own green screen and film wherever you like. You film your subject in front of a green screen background, and then using video editing software, the green is stripped (keyed or just removed) out and replaced with whatever background you choose to insert. A green screen is a simple method of setting your video in a location without actually traveling to that location. If you’re making a corporate or educational video, there’s a good chance you’ll want to use a green screen.
