Introduction to Chroma Keying and Cleaning

Chroma keying, also known as green screen technology, is a visual effects technique used to composite two images or video streams together based on color hues. The most common color used is green, but blue screens are also popular. This technique is widely used in film, television, and photography to create the illusion of various backgrounds and scenes.

In this masterclass, we'll cover:

Setting Up and Lighting Your Green Screen: Learn how to properly set up your green screen, including the type of material to use and how to light it to avoid shadows and reflections. Proper setup is crucial for achieving a clean key.

Keying Out Backgrounds Using Industry-Standard Software: We will walk you through the process of keying out backgrounds using software such as Adobe After Effects, Blackmagic Design Fusion, and Foundry Nuke. Each software has its strengths, and we'll explore how to get the best results from each.

Cleaning Up Edges and Removing Spill: Edges can often be problematic in chroma keying, leading to a visible outline or "fringe" around your subject. We'll show you how to clean up these edges and remove color spill to ensure a seamless composite.

Advanced Compositing Techniques: Once the keying is complete, the next step is compositing your subject into a new environment. We'll delve into techniques such as color matching, adding shadows, and integrating your subject into the scene to make the composite look natural.
