Gray signifies slight transparency, but ideally, you want the foreground to be entirely white (opaque) and the background to be pure black (completely transparent). There is room for improvement, as numerous gray areas are present. Navigate to View, and switch it to Screen Matte to evaluate the matte’s quality. Although the selection is pretty accurate, some refinements around the subject’s edges are necessary before proceeding. In our case, the green is consistent throughout. Use the dropper tool to pick the key color, aiming for a medium green shade that is neither too dark nor too bright, preferably near the subject’s hair. We’ll concentrate on the Key Light effect initially. Drag and place this onto your video clip, and observe the Effect Controls panel displaying all three applied effects. Although you can apply the Key Light effect independently, we will use Key Cleaner and Advanced Spill Suppression for this method. Head to the Effects menu and look for the Key Light effect. In After Effects, we will follow a popular removal process to remove the green screen.

Removing Portable Green Screen in After Effects It’s important to note that the compositional aspect of this tutorial is not important, so we’re not about to see some great wonders of compositing - rather, we’ll look at how well a portable green screen fares against AI removal tools. However, when moving the green screen further away, it’s important not to drop it out of focus, as shooting with a shallow depth of field could result in trouble when trying to key the green screen later on. So place the green screen a distance from the subject if they are standing in direct light. You’ll also want to ensure that your subject is not casting any shadows onto the green screen. You want to ensure that your green screen is evenly lit, without any shadows or hot spots, making removing the green background easier in post-production. Proper lighting is crucial when using a green screen, especially when outdoors.
Therefore, today, we will explore whether the trusty old portable green screen is still needed when the tools of AI are seemingly endless.įirst, let’s run over some portable green screen basics. Similarly, over the last few months, we have also seen a rapid increase in AI-based background removers, such as Runway’s ML tool online. In recent years, powerful machine learning tools like After Effects Roto Brush and Resolve’s magic brush have removed many tedious rotoscoping tasks. In this case, the rotoscoping job would also be a nightmare as the actress’s hair blows in the wind and bugs fly past the camera. A portable green screen allows the actress to move freely throughout the composition without laborious rotoscoping. In the days gone by, I would opt toward using the classic portable green screen to comp a more relevant location into the background. Not ideal for a shot of a hiker exploring old ruins in the mountains. For example, the ruin above is situated on the doorstep of a massive defunct power plant. However, while using these locations for short fantasy films is excellent, the locations themselves have often had society move on around them. As a fantasy lover, I am fortunate to have been born in Wales, where ancient castles and old derelict ruins are seemingly situated everywhere.
