Then I tried to use full-fledged 3D virtual sets based on Unreal Engine 4, but they require a lot of computing power, which is not suitable for a small filming studio. After trying the existing sets, it turned out that they did not suit me. The first program I worked with was vMix - it already implements a system for working with virtual sets. Quick story: About a year ago, I had to deal with filming and streaming video content using green backgrounds and virtual sets.
