PHYX = Perfect Chroma Keyer Addition for Final Cut Pro

February 11th, 2010 · 4 Comments

With the generous support of Noise Industries, PHYX Inc. has launched PHYX Keyer for FxFactory, which supports Apple Final Cut Studio, Apple Final Cut Express, and Adobe After Effects. Finally a plugin that rocks so well anyone will look good grabbing a key with this plugin. PHYX knocks it out of the park with this plugin. Not only do you get a great keyer but the additional filters takes a step further and makes it a necessity if you ever have pulled a key before.

It is so simple to use.

First drop the keyer plugin and select the color you want to pull with the eye dropper tool and then increase the Yuv Threshold until you have the color keyed. Then increase the Yuv Smoothing until the color is smoothed out around the subject.

If you can’t get rid of the slight green halo around your subject grab the despill plugin from the PHYX effects folder and apply to the footage. If the color you pulled was green select green in the drop down menu from the Despill Method and adjust the Despill Amount unti the green halo around the subject is gone. Now you need to be careful of your subjects skin color doesn’t change too much from the Despill filter.

I’m using a cloud generator behind my subject and I can add a small blur from the clouds around my subject with the Lightwrap filter. Drop the filter on the video file and in the filter under the background image grab an image that you would like to give a nice glow around your subject. With the clouds it makes a really nice glow and adds so much more to the key.

What took me 5 minutes, if that long, used to take me 20-45 minutes in Motion using many different filters and exporting footage. I could never remember the steps because there were so many. This filter is a dream and will help you key in a faster fashion. Don’t worry I won’t tell your clients, keep charging for your time.

Final Key

Other features that I’m looking forward to using…

Creates a matte based on difference between two images. For example, film an empty room (clean plate), then film the same room with actors present. DiffKeyer will create a matte of the actors, as if the actors were shot in front of a green or blue screen. This gives you the ability to effectively key without a green or blue screen. Here is a tutorial showing you how easy it is

So let’s say you shoot on a big green screen and the lighting is not even on the green screen well this filter compares a clean plate, and a solid color (green or blue) and creates a perfect green or blue screen. Excellent for keying with, this processor corrects unevenly lit screens, removes tracking markers, and repairs other ‘garbage’ which makes keying difficult, tedious, and expensive. Tell your clients you can do it. Another tutorial showing you how easy it is.

Go purchase this plugin and enjoy it.

    Great article – thanks. It’d be great to see something similar for the Screencorrector feature. The PHYX tutorial video you link to isn’t that helpful and I’m struggling to get it right. But thanks again!

    In After Effects, when using the PHYX keyer, I can enter in an RGB value or a hexadecimal value, but in FCP I cannot. Or at least I dont know how. Does anybody else know how to do it?

    Looks perfect, in the final key you don’t notice any green outline, tint or anything.
