The “green” green screen is identified by the video editing program and you can then replace it with another video or image. This is a popular method widely used in the media, from local weather reports to music videos and Hollywood blockbusters.
Adobe Premiere Pro, as a video editing program, has the ability to edit green screen footage using a technique called chromatic keying. In Premiere, you can use the Ultra Key effect to chromatically key your footage.
Follow this guide and you can easily add green screen effect to your videos.
How to Set Up Your Footage for a Chroma Key
Before you apply the Ultra Key effect, you need to clean up your green screen footage so that the final product looks better. You will be applying a matte to your video so you can get rid of the areas you don’t need for chroma keying.
After placing the green screen frame on the timeline, open the effects panel and choose Video Effects > Legacy. From here, select Eight-Point Garbage Matte if you have a simpler object as your green screen foreground. Choose Sixteen-Point if your subject is more complex. Below, I’m using a garbage matte with eight points, since the object is just a circle.
You can click on the effect in the Effect Controls window, which will highlight the matte points in the preview. This way you can move them around with the mouse or change the point position values ​​in the effect controls.
After you trim your video, we will move on to apply Ultra Key and Chroma key to your video.
How to Chroma Key In Premiere Pro Video Editor
Return to the Effects tab after you’ve applied the matte to find the Ultra Key effect. Follow the instructions below to apply it.
Go to Video Effects > Keying > Ultra Key. Click and drag this effect onto your clip.
In the Effect Controls panel, under the Ultra Key effect, select the Eyedropper tool. Use this to select the green screen background color. If the green screen lighting in your frames is uniform, you can choose any location. However, if there are areas that are lighter than others, choose a darker area.
As soon as you select green screen color, you will see that the rest of the color will disappear. Now you can start fine-tuning the key so that it blends seamlessly into whatever background you choose.
There are several different ways to fine-tune the edges of an object so that it blends naturally into the background. First, select the alpha channel from the Output drop-down list. This will change your footage to black and white, making it easier for you to see which areas need some work. If the white color in the alpha channel looks more transparent, it means that the selected color may be more visible there.
You can also change the settings dropdown to aggressive. This will allow you to select a larger range of colors that you selected with the eyedropper.
You can also look under the Matte Cleanup section. Here you will see some effects called Choke and Soften. The choke will cover the edges of your object with hard lines. Soften also closes the edges, but with a greater feathering effect.
Adding in a Background for Your Green Screen
Now you can do the fun part of adding a background of your choice to your video. This step is easy to follow and can help you see if you need to further change any part of your key for a natural effect.
Find the background frames you want to use for your green screen in your media selection.
Click and drag your footage onto the timeline. Make sure it’s on a layer below the green screen frames.
The selected frames will now appear below your theme on a green screen.
Now you can see how well your object fits into the new background material and make the necessary adjustments using the tools described above.
Tips for Editing Your Chroma Key
There are a few more tools that will be helpful in cleaning up your key so it blends well with your background or effect.
Transparency
You can find this setting under Matte Generation. Decreasing this value will harden and clean up the edges of your object, while increasing it will soften the edges. This option is useful for refining complex edges such as hair or fur, fibers, or other complex objects.
Pedestal
Changing the value of the pedestal determines how much of the background will be visible around the object. Decreasing this value will enhance this effect, while increasing it will create sharper edges.
Shadow
This value will change the visible “shadow” effect around the edges of your object, making the edges softer. This is good for making your object look more natural in the added environment.
