![]() ![]() This is useful for removing everything outside of a certain color range (instead of inside a color range). Invert will swap your key matte, making your keyed background opaque and your subject transparent. This often happens if your scene was lit improperly allowing light to reflect off the background onto the subject. If some of your background color is spilling onto your subject you can adjust the Spill level control to remove it. If you increase this too much you can create unwanted translucency near the edges. ![]() Edge DistanceĮdge Distance works together with Fill Holes to determine how far into the interior of your subject a “hole” must be before it gets filled. Increasing this slider does what you’d expect, if there are any unwanted holes inside your subject after using the Keyer, you can crank this up to fill them in. View gives you three options for previewing your chroma key effect, allowing you to see a Composite of the foreground and background, Matte which shows transparent areas as black and foreground areas as white, and Original allows you to see the image without the effect. If conditions in your footage change over the course of your clip, you can make multiple samples and adjust them independently using all of the Chroma Key. Jump to SampleĬlicking the left and right arrows next to Jump to Sample will bring you forward or backward to the next color sample. The default is 100%, but you can decrease this if you’re losing too much of your image to transparency. This slider narrows the range of colors identified by the keyer. So let’s say you wanted even more control over your effect, the Keyer comes with an entire panel of parameters which can come in useful if you’re working with imperfect green screen footage. With most high-quality green screen stock footage, these steps should do the trick of making your green screen effect look top-notch! The best green screens have consistent luminescence, no color spill, and light the subject independently. Either can be controlled by selecting it in the Timeline and adjusting its controls in the Inspector. You can adjust either the background image or the foreground subject with the keyer effect.Using the Transform controls such as Scale and Position, adjust the background image, so it is framed appropriately.Add your background image to the Timeline below your green screen clip.By placing an image behind your footage, you can composite the two together. Step 4: Compositing Your Background and ForegroundĪfter adding the Keyer effect, you should immediately see the green portion of your footage disappear. If the subject moves about, you may need to adjust the edges multiple times throughout the clip. ![]()
