LUTS or look up tables are a set of configurations that allow you to overlay cinematic color effects on top of your webcam input so that the output has a distinct separate appearance than the source camera/webcam image or video. LUTS allow you to improve even a budget or poor quality webcam by applying filters that can do color balancing, correction or simply add cinematic effects to your webcam and are worth experimenting with to find the right LUTS filters for you and your stream. Watch a free tutorial on how to use cinematic LUTS with open broadcast software and the same instructions can be followed with Streamlabs OBS or StreamElements since they are all using similar backend source code based on OBS anyway.
