The circles on the green screen stock footage are known as “chroma key markers,” which are used to help software accurately identify and remove the green screen background.
To remove the circles, you can use software such as Adobe After Effects or Final Cut Pro, which have built-in tools for chroma keying. First, apply the chroma key effect to the footage and use the eyedropper tool to select the green color in the background. Then, adjust the threshold and other settings until the green screen is completely removed, including the circles.
It’s important to note that the effectiveness of chroma keying depends on several factors, such as the lighting and quality of the green screen footage. It’s also important to use high-quality footage without any artifacts or inconsistencies, as this can make it more difficult to achieve a clean removal of the green screen background.
In addition to software, there are also hardware solutions available for chroma keying, such as green screen backdrops and lighting setups. These can help to create a more uniform and consistent background, which can make the chroma keying process easier and more effective.
