How to remove the background using AI in Davinci Resolve 18

Howto & Style

Introduction

Removing the background from your video clips can greatly enhance the production quality of your projects. In this guide, we’ll walk you through a simple method to eliminate the background using the AI tracking features in DaVinci Resolve 18. Let’s get started!

Step-by-Step Instructions

  1. Prepare Your Clip: Begin with a static clip where you’re positioned in the same spot throughout. This setup works best for accurately removing the background.

  2. Select the Clip: Choose the desired clip in the timeline, and navigate to the Color page.

  3. Creating the Mask:

    • Ensure that the mask overlay toggle is selected.
    • Use the brush tool to scribble a mask over your subject to define what you want to keep (you can create multiple masks for added precision).

  4. Inverting the Mask:

    • If necessary, you can invert the mask by clicking the appropriate button in the interface. For now, we want to remove the background, so keep it as is.

  5. Add an Alpha Output:

    • To remove the background effectively, add an alpha output by connecting the mask’s dot to the alpha output dot.

  6. Viewing the Result:

    • Although the background will be gone, you may not see noticeable changes on the Edit tab immediately. To visualize the mask, deselect the mask overlay in the Color page.

  7. Adjusting the Mask:

    • Return to the Color tab and adjust the settings by selecting “Better” from the dropdown menu for tracking quality.
    • Tweak the settings like “Clean Black” and “Clean White” to soften the mask edges and make it appear more natural.

  8. Tracking the Clip:

    • Use the tracking controls to analyze the clip. Track forward and backward with the AI, depending on your computer's hardware capabilities. This process should work smoothly.

  9. Adding a New Background:

    • Once the tracking is complete, return to the Edit tab. You’ll need to place a new backdrop beneath your clip. Ensure your original clip is on the second track to correctly display the new background.

  10. Final Adjustments:

    • Before you play back the clip, remember that modifying any transform settings in the Inspector tab will reset your mask, requiring you to retrack the clip. This process ensures the mask remains effective throughout.

  11. Play Your Clip:

    • Press 'P' to preview your clip and hit the spacebar to play. You should see the background replaced with your new choice, showcasing the final result.
