You know the infamous green or blue screens. After this your key is complete.Keying is an important part of AE if you are using items or characters on different backgrounds. You can also adjust the Advanced Spill Suppressor suppression level.You can try adjusting the Key Cleaner edge radius and strength. Generally the default settings will look pretty good but tweaking can help. Then search for Advanced Spill Suppressor and drop this effect on your footage too.Drag and drop the effect onto your footage. Next, search for Key Cleaner in the Effects & Presets window.As mentioned earlier, this view shows you the result without Keylight spill or color correction. First, set the view mode in Keylight to Intermediate Result.Rather than using Keylight automatic color correction we will use two other effects. Keylight will try to automatically get rid of the tint by color correcting it but this can lead to noise. Often times your subject will have a green tint when filmed on a greenscreen.Once you have created a clean key move on to the next step. Then try to remove black noise from the area you want to keep.Adjust the two options so there is no white noise in the area you want to key out. Again, use the Clip Black and Clip White options to fine tune your key.Instead, it uses white and black to represent what is and what is not being keyed out. This view is similar to the Status view but it does not exaggerate your key. Next change you view to “Screen Matte”.We will come back to this later.įine Tuning Your Key In Screen Matte View The Intermediate Result view does not show spill suppression or color correction by Keylight. 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.
