"Chroma key effects" refer to a technique in video editing where a specific color range in a video is replaced with another content. Typically, a uniform background with a color that differs significantly from the colors of the foreground objects or people is used. This color is then removed afterwards and replaced with a new image or video, creating the impression that the people or objects are interacting with a different background.
Typical features of software in the field of "Chroma key effects" include:
Color selection: The software allows selecting the color to be used as the chroma key, often through a dropper tool or manual color selection.
Tolerance value settings: There are options to adjust the tolerance value to control the degree of color removal and improve the accuracy of chroma keying.
Real-time preview: The software provides a real-time preview to show the user how the result looks before applying it.
Fine-tuning tools: Tools for fine-tuning the chroma key effect, such as edge masking, to make transitions between foreground and background more seamless.
Layering and compositing: The ability to combine multiple video tracks or layers to create complex chroma key compositions.
Export: The software allows exporting the finished video with chroma key effects into various formats for use in different media.
