In software applications that have this feature, such as Man圜am, users will select the color of the background with an eyedropper. Then, in editing, you can easily remove that green background and replace it with a shot of the Himalayas.Ĭhroma keying can be done with any backdrop color. Let’s say you place your camera between your subject and a green background to record a YouTube video. Want to enhance your video calls like never before? Try connecting Man圜am to your video calling app!Ĭhroma key and green screen, or chroma keying and green screening, are two different names for the same visual effect, which consists of layering two images or more together through color. In this blog post, you’ll find out why chroma key can be so relevant to live video, what are its possible applications and how you can use Chroma Key on live videos. Whether you want to make better video calls and conferences or create highly engaging live streams, green screen effects can help. However, it can also cause the problem of ‘green spill’ if the lighting and the subject’s distance from the screen is optimized before shooting.Chroma key can be a huge asset to live video.

Since there’s no green in a human’s skin tone or clothing, it offers a better contrast between the subject and the background and can therefore be keyed out easily, without affecting the other elements of the picture.Īnother reason that green is used is because it has the highest luminance among all the color channels (RGB), which makes green screens very bright (because of their high luminance). This is why you want to choose a screen with a color that has very little chance of matching anything in the foreground. For example, if the subject is wearing a green badge on his body, then that portion would be keyed out while editing, making it look like as if there’s a hole in his body. Consider this: if anything in the foreground has the same hue as the color you want to key out (in this case, green), then it will be keyed out too. The most basic one is the fact that green ‘stands out’ reasonably well while filming any footage. That being said, why is green the most commonly used color in videos and movies involving a lot of visual effects? There’s no obligation to use the color green. You can use any color, such as yellow, purple, red, or pink, to use this feature. There’s no hard and fast rule, either technologically or ethically, about using a particularly colored screen when you want to apply Chroma Key. You can’t actually recreate the scene in the real world, since you can’t make actors dart through actual bomb strikes (unless you want to spend millions of dollars on every take and likely end up in prison), but at the same time, you want to make the scene look as authentic as possible. More specifically, you want to show the actors running through ruins and constantly evading aerial attacks. For instance, let’s assume that you want to shoot an action scene from a superhero movie. While shooting videos that involve a lot of visual editing, you need to consider a few things, namely things that will facilitate editing in the later stages of post production – during the shooting itself. Since you’re most likely to see the use of green or blue screens in action, fantasy or sci-fi movies – or during weather forecast reports – it doesn’t take a rocket scientist to figure out that the green screen must have something to do with the one element that is common in all of these different media – visual effects and animation.
