Select New Project if you want to start from scratch, or open an existing project if you plan on adding chroma key to a composition you’ve already made. Just drag and drop it into the timeline. This can also just be Premiere’s default background colour. For optimal effectiveness, they will always have a flat coloured background commonly green, hence why the effect is also known as ‘green screening’.
Drop these clips onto the timeline above the background. Resize and adjust the clip until you are satisfied with its size and position. If it will be a full-screen effect like this clip of falling leaves , resize until it completely covers the screen. Search up the effect. Make sure you are in the Effects tab indicated at the top , where there should be an ‘effects’ search bar on the right.
Inside, type key. There will be many different effects, but Ultra Key is the most effective one. Click and drag Ultra Key onto the clip you will be processing. On the left, the ultra key settings will appear in the effect menu. Go to Key Color in the settings and click dropper. It will now transform your cursor into a colour selector. Click on a green or plain colour bg part of the clip. You will notice that most of the green will disappear.
Instantly, we have a pretty darn good looking key. Change the Output menu from Composite the final result to Alpha Channel. This displays the key in shades of gray. Your goal is to get the foreground solid white opaque , while the background is solid black transparent. Any shades of gray indicates translucency which, in general, you want to avoid.
This image was shot and lit pretty well, notice there is a clear delineation between foreground white and background black. Switch the Output to Composite and you could stop here. Click the Motion icon, to enable dragging the image in the Program Monitor, and drag the image off-center to frame it better against the background. In other words, a typical production shot.
This is especially true of green-screen work. To begin, follow the steps above, select the color and then switch to Alpha Channel mode. The green background is more gray that black. Worse, even the garbage is white. Not good. We are going to take this in three steps:. In the Effect Control panel, twirl down Matte Generation , then adjust Transparency until the foreground you want to keep is solid white.
This slider controls the foreground separation. The best way to adjust this is to slide it until you find the point where the foreground becomes transparent, then move the slider a little bit until the foreground is back to solid white. Next, twirl down Pedestal and do the same thing, except now you are adjusting the background to be solid black. Switch the Output back to Composite and take a look at the finished results.
Your goal, even with bad keys, is to get the background immediately behind the talent to be solid black, even if other areas of the frame are not. These two controls should allow you to nail the key, though, in this case, the poor lighting is making our life difficult. If you need to adjust the edges to remove excessive spill, or halos, twirl down Matte Cleanup.
This crops in the edges of the image and a little goes a long way. Then, add a bit of blur to the edges with Soften. Again, small amounts are always the best option. To remove green around the edges, twirl down Spill Suppression and tweak Desaturate. Remember, the easiest way to avoid excessive spill is to separate your actors from the background. NOTE : There are also color correction settings with this filter, but we have far more control over color using the Lumetri Color Panel; which is what I would normally use.
Make sure the green screen clip is still selected, then twirl down Opacity in Effect Controls. Then, click to draw a border around the objects you want to keep. To add a curve, click-hold-and-drag.
Click the starting point to close the circle. And, yup, I moved the foreground image to the right and added a Gaussian Blur to the background. Do have any recommendations on those?
