We’ve put together this short article and video that shows the editing process for extracting – or keying – greenscreen. It isn’t intended to be an in-depth tutorial, but to show the layman how straightforward this task can be and why they can consider filming on greenscreen as a realistic option.
For the purpose of this video we assume the viewer knows the basics of editing: that is, how to set up a project, import footage and place it ready for editing. This video starts from that point to specifically show the ‘keying’ out of green and adding in the background ‘compositing.’
We hope you found the video helpful and it dispels concerns you have about greenscreen filming and the post-production process.
It’s worth pointing out there are a lot of terms used to describe the same process. To some extent they are interchangeable. For example ‘chroma-keying’ and chroma-key compositing mean the same thing in practical terms – mixing two or more images or video into one so they appear they as if meant for each other.
‘Chroma’ and ‘greenscreen’ mean the same thing with this qualification: Chroma could be any colour, though typically green or blue are used (because they are the furthest removed from the colour of human skin). We have an interesting article exploring the use of greenscreen vs bluescreen, here.
TOP TIP: Check there is nothing green in anything being filmed – let your talent and wardrobe department know well in advance. If there is green (eg plants) then consider chroma-blue. Historically the weather reports have relied on blue-screen.
These days greenscreen is far more likely, perhaps 95% or more of our chroma shoots are on green. They include news broadcasting, explainer pieces-to-camera, animation, music videos, corporate ads, fashion, just about anything … except plants.
