How To: Fix Green Screen Problems





Segments include:

Rough and Discolored Edges
Green Screen work is complex, even under ideal circumstances, and working with footage that hasn't been lit or shot properly can be pretty tough. In this segment, we show you how to fix those rough and discolored edges that are often left after pulling an initial key.

Unwanted Green and Spill
When you're shooting footage next to a gigantic green wall, it's not unusual to have some of that green unintentionally fall on your subject. In this segment we show you how to remove the green spill using keylight, spill suppressor, and curves in Adobe's After Effects, Ultra Key and the three-way color corrector in Premiere Pro.

Subject Doesn't Match the Background
After the time-consuming process of pulling a good key is finally complete, placing your subject in the scene can sometimes seem like an afterthought. In this segment we talk about positioning your subject in the shot, color correcting your subject to match the background, creating a lightwrap to blend your subject into the background more naturally, and how to deal with mismatched lighting.

Source Footage has a Camera Move
"Green Screen shots with camera movement with the background and foreground in perfect sync helps sell the scene. In this segment, we show you how to track motion in your shot, sync your background with your footage, stabilize shaky footage, and manually keyframe motion. These techniques can help make your scene appear more real, and save otherwise unusable footage.

Multi-Layered Keys and Rotoscoping
Even the best green screen footage can present issues that can't be corrected with standard keying procedures. Whether it's a particular movement in the scene or rough lighting, sometimes you'll need to use alternative methods to isolate your subject from the background. In this segment we demonstrate multi-layered keys, and how to use masks to rotoscope your subject. These advanced methods and can help you get difficult green screen footage looking good.

Fixing Uneven Lighting and Unwanted Objects for Green Screen
We've all seen the tutorials that show you a one click process to pull a beautiful key. But many times, the lighting on the green screen shot you're working with isn't lit perfectly, and has objects in the shot that you don't want. In this segment, we show you how to remove unwanted objects from your footage, and key out a background that has uneven lighting. Knowing how to fix these issues is the starting point to pulling a great key, even when the footage presents a challenge.
