You can use the background for advertising.You can change it according to the topic, your script, or the response from your audience. You don’t have to stick to one background. The background can change during the stream.The background visuals are added independently. You can stream from any location where you can set up a green screen and have the same visuals in the background. It makes you independent of your location.So why would you need a green screen for a live stream?Ĭhroma keying has many applications in live streaming, such as: You’re also probably sensible enough to avoid doing dangerous things in your streams. □ The use of a green screen in live streamingīut if you're a live streamer, you’re not making movies, right? It’s not likely that the use of chroma keying will save you a ton of production money. Even mundane stunts like driving a car are filmed in front of a green screen to make them safer and less demanding for actors. Traveling, insurance, and filming licenses cost money.Īlso, it’s often much safer for actors to do stunts in front of a green screen than in genuinely dangerous locations. Using a green screen can be cheaper than building real movie sets, as it tends to be less expensive than organizing production on location. Chroma keying helps directors and creative teams achieve their vision, and it’s responsible for some of the most memorable moments in cinema.Ĭhroma keying also saves money. The big Hollywood productions use it, as do small independent films. Green screening is an extremely popular technique that originated with movies. It’s really easy to do - we’ll guide you through it and help you grasp chroma keying in OBS. The main difference is that you have to replace the green screen as you’re filming, rather than during editing. You film something or someone in front of a colored background - the green screen - then you replace everything that’s in the color of the screen with other footage, images, charts, presentations, or whatever visuals you want.Ĭhroma keying a live stream works almost the same way. You probably already have an idea of how to use a green screen, at least in principle. It doesn’t have to be green at all, though, and the technical term for it is “chroma keying.” Plus, it doesn’t look very natural for any human to have a green tint to their skin.What does the weather forecast on your local TV station have in common with a $300 million blockbuster? They both use the same visual effect: a green screen. NOT something you want because, again, it will make the keying out process very difficult in post production. If your subject is an actor, it may look like there is a “green halo” or a green reflection on their skin. When there is too much light on the green screen, green fuzzy edges can be seen around your subject. Now that you’ve evened out all the lighting, the opposite effect can also happen - too much light on the green screen. Consider hiring or consulting with a knowledgable gaffer for your production. Bravo Studios has a roster of talented crew suggestions for your next production. This is why a Gaffer - a person who is in charge of the design and execution of the lighting plan on set - is so important. Try adding lights aimed at the green screen to even everything out. This is because there are still dark and light areas in the background. Again, this will make the chroma key process difficult. Now that you’ve removed the shadow, you may have another problem - an unevenly lit green screen. You can also think about adding lights behind your subject aimed at the green screen to brighten up the dark areas. Also avoid using just a single light or very harsh frontal lighting. Move your subject away from the green screen background a bit to reduce the shadows. This will cause a shadow to cast on your green screen. Shadows make the chroma key process difficult because the dark areas that the shadow cast on the green screen are too similar to the dark areas that the shadow cast on your subject making it difficult to key them out perfectly. Shadows often happen when your subject is too close to the green screen or due to very strong lighting, especially strong frontal lighting. Shadows may be detrimental to your green screen production because it may make your chroma key process difficult in post-production. Bravo has compiled 5 top common mistakes or challenges in a typical green screen video or photo production. Bravo Studios, New York City’s leading green screen stage rental, has been in the green screen and video production sphere for decades.
