![]() A presenter could easily throw up a green screen and let their production teams work their magic to “transport” them to a more suitable “location” simply by chroma keying the background.Īlthough the technique was developed initially for canned video in the days of analog film photography, modern live broadcast software allows you to use chroma key with live streaming as well. This is used a lot in shows and movies, but it has become more important since people have had to quickly pivot and record in less than ideal spaces.įor example, early COVID-19 related lockdowns required that large-scale events be recorded from home and other unusual locations. For example, the producer could use a green screen in the background of the recording setup to seamlessly add a different background of a design or a different location. Top Chroma Key Software for Live StreamingĬhroma keying, which is also referred to as “chroma key compositing,” is a cinematic technique that is used to blend two different media files together by picking up on color hues.Here, too, you then switch the output back to image. Using the sliders that adjust the weighting of each color component, you can adjust the effect so that the areas to be cut away appear as dark as possible and the colors to be kept appear as light as possible. The smaller the difference (darker), the more likely the spot will become transparent. The Color difference option shows what the Chroma key effect sees internally, namely the difference between the key color and the image. Most of the time you will change the output mode back to Image afterwards. For example, switch to the "Mask" output mode to find the best setting for the thresholds, since "dark spots" are immediately visible here. This allows you to evaluate and tune your effect in a more sophisticated way. Output - Choose which result you want to be displayed in the Layout designer: the generated image, the original, the chroma key mask or the color difference.Invert - Everything will be displayed transparent except the area with the selected color. ![]() ![]() Keep shadows - Shadows that lie on the color key will be displayed dark. ![]()
