remove green screen from video after effects

You can see the difference before and after by comparing the Final Result view to the Intermediate Result View.

Anything that is green represents areas that Keylight will attempt to color correct to remove spill. Again, try to keep a small amount of gray near the edges of your subject. Next decrease your Clip White until your subject becomes almost entirely white.

Increase your Clip Black until the background becomes black.

The top two options here, Clip Black and Clip White, are the most important.

To achieve this, expand the Screen Matte menu under Keylight settings.

The next goal is to make as much of the background solid black, then make as much of the foreground solid white, while retaining a very small amount of gray around the edges.

This view exaggerates the key to show you what is being keyed out completely, partially, or not at all by using black, grey, and white respectively. To do this, choose the Status option under the View dropdown in the Keylight settings. The first step to improving your key is viewing it in a different way.

After clicking, you will see that the color is mostly removed, however, it is rare to get a perfect key without further tweaking.

Try to get as close to your subject as possible while still selecting the color and not the subject.

Move your mouse to the color you want to key out and click.

First, select the Eyedropper tool next to Screen Colour in the Keylight effects settings.

This will mask out the extraneous parts of your shot.

Next draw a rough mask around your subject while leaving enough room to contain any of their movement.

Select your footage then select the pen tool.

This is a mask that is big enough to contain our subject but small enough to remove parts of the shot you want to get rid of. To get rid of this, create a garbage matte around the subject.

Your shot will often have objects on the edge of the frame you want to remove such as lights or stands. Often times a green screen shot will not make use of the entire frame. You should now see Keylight listed along with it’s settings. Now select your footage and open the Effect Controls panel. Select Keylight 1.2 and drag it to your footage. Then go to the Effects & Presets panel and search for Keylight. If the frame below the playhead isn’t representative of the rest of the clip, reposition the playhead and reapply the effect.Place your footage in the timeline.

The colour that iMovie removes is based on the dominant colour in the frame at the position of the playhead when you choose Green/Blue Screen from the pop-up menu.

As the clips are connected, the two clips move together if you rearrange clips in the timeline. In the viewer, iMovie removes the green or blue from the green-screen clip to reveal the background clip behind your subject. If the video overlay controls aren’t shown, click the Video Overlay Settings button above the viewer, then choose Green/Blue Screen from the pop-up menu.As the clips are connected, the two clips move together when you rearrange clips in the timeline. Trim and move the background video clip to match the length of your green-screen clip.Add the green-screen clip above the background clip in the timeline.With your project open, add the background video clip or still image to the timeline.
