Explore keying effects on this Adobe Premiere Pro help page to learn how to remove backgrounds and isolate subjects using chroma keying.
Keying effects in Premiere Pro help you easily remove backgrounds, like green screens, or highlight parts of your video for cool visual effects. Tools like Ultra Key or Luma Key can blend footage and create smooth composites.
Alpha Adjust effect
Use the effect in place of the Opacity effect when changing the default render order of Fixed effects.
Adjust the Opacity percentage to create levels of transparency.
Color Key effect
Use the effect to key out all image pixels like a specified key color. This effect adjusts only the alpha channel of a clip.
Luma Key effect
Use the effect to remove all areas of a layer based on specific luminance or brightness levels.
It works best when the object you want to generate a matte has a significantly different luminance than its background.
For example, when keying musical notes on a white background, you can remove the brighter areas so that only the dark notes remain visible and opaque.
Track Matte Key effect
The Track Matte Key reveals one clip (background clip) through another (superimposed clip), using a third file as a matte that creates transparent areas in the superimposed clip. This effect requires two clips and a matte, each placed on its own track. White areas in the matte are opaque in the superimposed clip, preventing underlying clips from showing through. Black areas in the matte are transparent, and gray areas are partially transparent.
A matte containing motion is called a traveling matte or moving matte. This matte consists of either motion footage, such as a green-screen silhouette, or a still image matte that has been animated. You can animate a still by applying the Motion effect to the matte. If you animate a still image, consider making the matte frame size larger than the sequence frame size so that the edges of the matte don’t come into view when you animate the matte.
Ultra Key effect
Use the effect to remove a green or blue screen from your footage, making it easy to drop in a new background. It's great for clean, pro-looking composites and gives you controls to fine-tune edges, color spill, and more. For example, swapping out a green screen behind a person with a different video or image background.
