Compositing is an essential technique in visual effects (VFX) and computer graphics. It involves combining multiple images or video streams into a single composite image or video. This technique is widely used in movies, television, and video games to create realistic scenes or enhance visual storytelling.

What is Compositing?

Compositing is the process of combining two or more visual elements into a single image or video. It is often used to create scenes that would be impossible to capture in a single shot or to enhance the visual quality of a scene.

Types of Compositing

  • Keying: Also known as green screen or bluescreen, keying involves replacing the background of an image with another image or video.
  • Matte Painting: This technique involves painting a background image and compositing it with the subject.
  • Blending: Blending involves combining multiple images or elements in a way that they appear seamless.

Compositing Workflow

  1. Preparation: Gather all the necessary images or video streams.
  2. Keying: Remove the background from the images or video streams using keying techniques.
  3. Matte Creation: Create matte images for complex backgrounds or scenes.
  4. Blending: Combine the images or elements using blending techniques.
  5. Finishing: Adjust the lighting, color, and other effects to create the final composite.
