The use of chroma keying has become quite popular in recent years, with many applications of this video effect used for live streaming. Chroma keying is used to remove the background of a video scene which is then composited over another scene or image. The most obvious use of this technique is for weather broadcasts, where the presenter is composited over the top of a weather radar image. In more recent times we’re seeing video game streamers chroma keying themselves into their live streams.
As with all things in video production, you can easily spend a fortune on equipment. For the purpose of this guide, we’ve tried to keep things reasonably cheap. For the green background we picked up some green fabric from a local arts and craft store. Alternatively, you can buy green screen paint if you’re looking for a more permanent setup.
This involves using OBS Studio with The Alturatek HD 1080p WEBCAM and Adobe Premiere Pro. Budget Green Screen cloth from Walmart which is just fabric. Lighting is very important when it comes to green screens as you want the green to be as even as possible. In our set up we’ve used a single box light. We’ll go into more detail about lighting below.
