Eat Apple News Video Review:

Green Screen Studio is a chroma key application that allows the user to change a monochromatic background into any image they wish. Chroma key is a technique for mixing two images or frames together, in which a color from one image is removed (or made transparent), revealing another image behind it. This technique is also referred to as color keying, color-separation overlay, greenscreen, and bluescreen.

Green Screen Studio has tools available to manually remove the background if you do not have a perfect greenscreen background available. This allows you to manually apply backgrounds to any picture you want without a greenscreen.

  • Apply backgrounds automatically
  • Apply backgrounds manually using a selection of tools without having a green screen
  • Zoom in for finer editing
  • Zoom preview window for finer editing
  • Move image layers


    Green is currently used as a backdrop more than any other color because image sensors in digital video cameras are most sensitive to green. The green camera channel contains the least "noise" and can produce the cleanest key/matte/mask. Additionally, less light is needed to illuminate green, again because of the higher sensitivity to green in image sensors.

    The biggest challenge when setting up a greenscreen is even lighting and the avoidance of shadow, because it is best to have as narrow a color range as possible being replaced. A shadow would present itself as a darker color to the camera and might not register for replacement.

    A chroma key subject must not wear clothing similar in color to the chroma key color(s) (unless intentional), because the clothing may be replaced with the background.
