Part 1. How to Use Green Screen in Blender
Let's go through the steps on how to make amazing videos using the chroma key in Blender video editor.
Set Up Your Shot
Before you start editing, you need to record your video. Make sure you have a solid green background, like a big piece of green cloth. The more even the green color, the better your final result will be. You also need good lighting to avoid shadows on the green screen.
Steps to Use Chroma Key in Blender Video Editor
Step 1:Get Blender Video Editor
Download and install Blender on your device. Open it, and click VFX to proceed.
Step 2:Set Up Your Project and Import Footage
Then, select the dimensions for your video. Go to the Compositor workspace. Click on the "Movie Clip" node to import your green screen footage.
Step 3:Create a Chroma Key
Add a "Keying" node to the compositor. Connect the output of the Movie Clip node to the Image input of the Keying node. Adjust the Keying nodes in Blender chroma key settings:
- Screen Color: Use the eyedropper tool to select the green color from your footage.
- Clip Black: Increase this value to remove darker shades of green.
- Clip White: Increase this value to remove lighter shades of green.
- Screen Balance: Adjust this to fine-tune color selection.
- Despill: Use this to reduce green spill onto your subject.
- Edge: Refine the edges of the keyed area.
Step 4:Preview the Keyed Footage
Add a "Viewer" node to preview the result of the keying process. Connect the output of the Keying node to the Image input of the Viewer node.
Step 5:Add a Background
Use an "Image" or "Movie Clip" node to import your desired background. Position and scale the background as needed.
Step 6:Combine Layers with Alpha Over
Add an "Alpha Over" node to combine the keyed footage with the background. Connect the output of the Keying node to the "Foreground" input of the Alpha Over node. Connect the output of the background node to the "Background" input of the Alpha Over node.
Step 7:Refine the Composition
Use additional nodes like "Color Correction" or "Grade" to adjust colors and contrast. Add effects or transitions as desired.
Step 8:Render Your Output
You can create a new video with your changes. This is called rendering. Add a "Composite" node to output the final image. Adjust render settings (resolution, format, output path) in the Render properties panel. Then, click "Render" to create your final Blender green screen video.

Even the pros face challenges with green screens, especially with Blender's green screen. However, many issues arise while shooting. Here are some common problems and how to fix them.
- Uneven Lighting
If your green screen is too bright or dark in spots, you'll get shadows or uneven color. Adjust your lights to create a more even glow on the green screen. The Chroma key blender video editor also has a feature called "spill removal" nodes to help.
- Green Spill
Sometimes, a little bit of green can sneak onto your subject. To fix this, use tools like "Desaturation" or "Color Balance" to remove the green tint without affecting your subject's colors.
- Edge Problems
The edges of your subject might look a bit fuzzy or have green halos. You can often fix this by adjusting the "clip black" and "clip white" values in Blender. Filmora has an "Edge" setting that can help clean up the edges.
Tip! Practice makes perfect! Keep experimenting with different settings and techniques to achieve the best results.
