Twirl the triangle next to Screen Matte and increase the Clip Black until your background is solid black.

We want the subject to be white and the background to be black. Black is transparent, white is opaque, and gray is in-between. You will now see what is transparent and what is opaque in your footage.

Then click on the little box that says Final Result and choose Status.

Then click on the footage where the color you wish to key out is the most prominent.

Now, in the Effect Controls window on the left of your screen, where it says Screen Colour, click on the little eye dropper.Apply this effect to your footage by clicking, holding, and dragging this effect over the footage in the composition window.

In the effects panel search for the effect Keylight (1.2), which is under Keying. Bring in your footage to a new composition.This works with any color, but a properly lit green or blue screen will yield the best results. I would definitely experiment with it again, possibly next year when I get the chance to make my own film.In this article, we will discuss how to chroma key out a background from your video. It is an interesting subject and a great experience. I enjoyed filming in the green screen room and I wish I had more time to do some more work within special effects. I found creating a video on After Effects quite simple because it was straight forward. I dragged and dropped the background After Effects. Then I had a look on Google images for a background for my green screen and found a space theme background on: Then on Hue and Saturation, I changed the Channel Control to Greens and adjusted the Channel Range to decrease the colour of green to black and white which disguises the green screen even more. Then I clicked Effects on the top tool bar and selected Colour Correction > Hue and Saturation.

I increased the Clip Black which increased the black colour on the video and I reduced the Clip White to make the white areas all white instead of grey because otherwise it would be see through.įurthermore, I increased the Screen Softness to create soft edges around my subject. This effect enables you to see the green screen areas that are still visible which couldn’t be seen on the normal setting. This made the image turn into a threshold effect. Then by selecting the drop down tab next to View, I selected Screen Matte. After increasing the Screen Gain it made it all black apart from the faces.

Then I Increased the Screen Gain because the green screen was still slightly visible in areas. Then the keylight options appear and I changed the Screen colour from black to the colour of the green screen on my video by using the sampling tool beside the colour. Then selected Effects > Keying > Keylight (1.2) Firstly I opened up my green screen video up in After Effects.
