What is Keying Out in Video Editing?
Keying out is a post-production technique in video editing, primarily used to remove a specific color (usually green or blue) from a video. This is also referred to as “Chroma Keying.” The concept behind keying out is that it’s easier to isolate a singular color and remove it from the video, allowing editors to superimpose images or scenes in its place. This technique is widely used in filmmaking, broadcasting, and even by influencers and YouTubers for creating special effects or changing the background of a video.
How Does Keying Out Work?
The process of Keying Out involves the following steps:
- Shooting the video against a solid green or blue screen.
- During post-production, the editor uses a chroma key filter to identify and remove the chosen color.
- The removed color area becomes transparent and anything placed under that layer becomes visible.
Why Use Keying Out?
Keying Out is essential in video production due to the following reasons:
- Flexibility: It allows filmmakers to shoot scenes in a controlled environment and later add different backgrounds or effects in post-production.
- Cost-effective: It reduces the need for expensive location shoots or creating large sets.
- Creativity: It opens up endless possibilities for creating imaginative scenes and special effects that would otherwise be impossible or impractical to shoot.

- Use a high-quality camera to capture clear, sharp footage.
- During post-production, adjust the settings of your chroma key filter to ensure a clean and precise key.
In conclusion, keying out is a powerful video editing technique that can elevate your content creation skills to new heights. Whether you’re a filmmaker, influencer, or YouTuber, mastering this technique can open up a world of creative possibilities for your videos.
