How to Create Green Screen Video Effects with Lightworks
Chroma keying may be the expression used for shooting video against a blue or eco-friendly screen, making the backdrop color transparent, and superimposing it more than a still image or any other video.
It’s broadly utilized in TV and films, with actors filmed before a colored backdrop inside a studio, which is then substituted for footage shot on location elsewhere, but you should use exactly the same technique both at home and it’s much simpler than you may expect.
