Introduction

This tutorial provides a quick and straightforward guide on how to use the green screen or chroma keying technique in Davinci Resolve. This effect allows you to replace a solid green background with any image or video, making it a popular choice for video production, streaming, and creative projects.

Step 1: Set Up Your Project

• Open Davinci Resolve and create a new project.
• Import your video footage with the green screen background:
  • Click on the "Media" tab.
  • Drag and drop your video file into the media pool.

Step 2: Add Your Video to the Timeline

• Switch to the "Edit" page by clicking on the "Edit" tab.
• Drag your green screen video into the timeline.
• Ensure that the video is placed on a track above the background you want to use.

Step 3: Apply the Chroma Key Effect

• Select your green screen video in the timeline.
• Open the "Effects Library" on the left panel.
• Navigate to "OpenFX" and find the "3D Key" effects.
• Drag the "3D Key" effect onto your video clip in the timeline.

Step 4: Adjust the Key Settings

• With your video clip selected, go to the "Inspector" panel on the right.
• Locate the "3D Key" settings:
  • Use the eye dropper tool to select the green color in your video.
  • Adjust the "Key Color" settings to refine the effect:
    • Increase "Threshold" to remove more of the green.
    • Adjust "Clean Black" and "Clean White" sliders to improve edges.

Step 5: Fine-Tune the Edges

• Scroll down to the "Matte Finesse" section in the "Inspector":
  • Use the "Soften" slider to smooth out jagged edges.
  • Experiment with "Invert" if necessary to correct the keying.

Step 6: Add Your Background

• Drag your desired background image or video into the timeline under your keyed green screen video.
• Ensure that the background is on a lower track so that your subject appears in front.

Step 7: Review and Adjust
