A green screen is a large green backdrop that's used to film people or add visual effects to videos. The green screen is then digitally removed in post-production, a process called chroma keying, to reveal the subject in front of a new background.
Green screens can be used to:
Add interesting backgrounds
Vloggers often use green screens to add interesting backgrounds to their videos.
Showcase objects and locations
Green screens can be used to digitally showcase objects and locations to help explain a concept or tell a story.
Create dramatic effect
For example, you could film a comedic skit set in the Arctic and add the tundra to the background.

Use good lighting: Good lighting is important for great results. .
Set up the green screen tightly: Set up the green screen as tightly as possible and hang it slightly slanted towards the ground to reduce spill.
