How to make a chroma key in OBS and substitute the desired background instead of a boring room in the back? If you haven’t tried bringing your own image into the game before, it’s time to start. 

We will tell you how to use the built-in features of the program and get a fundamentally new picture.

How it works

Chromakey in OBS Studio is an option that anyone can use with just a little effort. If you have not yet understood what this is about, we will set up a special background for displaying on the stream.

To understand what an OBS chroma key is, you can turn to the shooting of any movie or clip. This is especially true of fantastic stories! 

Don’t you think the scenes are filmed with dragons and medieval castles in the background? Of course not!

The actors play against a green background – this backdrop is called the Chroma key (or just a green screen). With the help of special technology, any desired image or video is placed on this static background

In this case, the actors find themselves as if inside the picture – they move, talk, interact.

Setting up a chroma key in OBS involves putting a streamer into the game. By default, the webcam window displays an image that falls into the frame – not only your face, but also the room in the background, and so on. 

If you set up a green screen, you can embed yourself in the online broadcast.

Only you will be displayed – up to your waist (as recorded by a webcam). The background will disappear completely! Interested in how to create a chroma key in OBS Studio ?
