Green screen, or chroma key compositing, has been around since the 1930s. Developed by filmmakers at RKO Radio Pictures, it was used as a method to create complex visual effects that were before its time. Over the years, the process went from a painstakingly analog method to a digital method that can now be done on computers. Programs such as Final Cut Pro, Premiere Pro, Avid Media Composer, and the like all have the ability to do basic greenscreen/bluescreen keying if your footage is in the optimal conditions. For complex and intricate situations, post professionals turn to programs like After Effects, Motion, Autodesk Smoke, or Nuke. Despite the programs that have greenscreen keying capabilities, there are many third party companies who have developed plugins to handle even the toughest keying processes. Let’s take a look at a few and see what each have to offer.
Primatte Keyer is Red Giant’s premiere keyer solution for post professionals. Within its array of features are some of the following: auto compute algorithm for pulling a perfect key, key correction tools for refining mattes and backgrounds, and color matcher feature for matching the subject to their background. This plugin is one of the most trusted keying plugin on the market amongst professionals in film (Lord of the Rings, The Matrix, Harry Potter, and Spider-Man) and television (Sesame Street, Nickelodeon, and Disney). This plugin is compatible on Mac and PC with programs ranging from Final Cut Pro, After Effects, Premiere Pro, and Motion. I can personally attest to its strengths and abilities as I’ve used it in my work quite often. I find it great to use when Keylight may not be enough to get the job done. For the price of $499, it is definitely a keyer solution to consider if you do a lot of it. Just take a look at its capabilities below.
If you are fine with keying with Keylight, you can get the tools of Key Correct to assist you. Key Correct lets you create perfect keys from an image shot against a colored background. These tools include a Rig/Wire Remover, Light Wrap, Color Matcher, Alpha Cleaner, and many other tools. I’ve personally used Key Correct’s tools on many projects and found it to perfectly complement Keylight when I may have challenging keys. Having both Key Correct and Primatte Keyer are definitely tools you should consider in your post production pipeline.
Boris Chroma Key Studio
Within the Boris Continuum Complete set is the Key and Blend unit. This unit automates the creation of precise keys with a minimal amount of adjustment. These filters strip away the complexity of chroma keying by automating matting, edge softening and refinement, and light wrapping and reflections to produce seamless composites each and every time. One plugin that stands out is the Chroma Key Studio. The Chroma Key Studio is an all-in-one keying suite similar to Primatte Keyer. It can do everything from screen enhancement, auto-garbage matte and masking, chroma key, matte cleanup, matte choker, foreground color correction, and light wrap into a single filter. In the tutorial below, Kevin P. McAuliffe demonstrates how versatile this plugin is and why it is a suitable solution for keying within your NLE. I’ve used it myself a few times and it is definitely a time-saver if I’m working in Premiere Pro or Media Composer as opposed to shipping it out to After Effects for chroma keying.
The final keyer plugin on the list is the one from the Phyxware folks. Phyx Keyer 5 is a set of 10 plugins designed to give you even faster and more accurate keys than ever before. These plugins include the FastKeyer, ScreenCorrector, Lightwrap, and SkinTools. These tools have been used by companies such as AT&T, Autodesk, and Fox Sports. These plugins were also used on the feature film Anchorman 2: The Legend Continues. In the tutorial above, you get to witness how versatile and fast these set of plugins are, whether you are in an NLE or compositing program. One thing to note about these plugins is that they function on Mac only and are installed through the FxFactory software engine. I’ve personally used the Keyer and other tools in this set, and I have to say that it is top notch. They really have tools to handle even the most difficult keying scenarios.
