How to Chroma Key Green Screen Effects in KineMaster Editor

KineMaster is a powerful yet easy-to-use video editing app for mobile devices. With KineMaster, you can create professional-looking videos right on your phone or tablet. One of the most popular effects in video editing is using a green screen, also known as chroma key. The green screen effect allows you to replace any solid background color with another video or image. This opens up endless creative possibilities.

In this comprehensive guide, I will walk you through step-by-step on how to use chroma key to create stunning green screen effects in KineMaster. As an experienced video editor and KineMaster user for over 5 years, I will share tips and tricks to help you master the chroma key tool.

Step 1: Set Up Your Green Screen

The first step is preparing your green screen setup for filming:

  • Use a wrinkle-free, non-reflective green fabric or green paper backdrops as your background. The green should be a bright, lime green color. Avoid using materials with different shades or textures.
  • Make sure you have consistent, even lighting on the green screen. Use soft box lights on both sides to properly illuminate the background and avoid shadows.
  • Position your camera on a tripod and place your subject at least 6-10 feet away from the green screen background. Frame your shots correctly before you hit record.

Pro Tip: Record a few seconds of just the green screen to use as your background plate later.

Step 2: Import Media to KineMaster Timeline

Open the KineMaster app and create a new project. Tap on the “Media” icon and select the videos you want to use:

  • Background video – this will replace your green screen footage
  • Green screen video – the clips you recorded with a green screen background

Import your videos to the timeline. The green screen clips should be above the background video layer.

Step 3: Activate Chroma Key Tool

With your layers set up correctly, now we can key out the green:

  • Select the green screen clip on your timeline
  • On the right menu, scroll down and click on “Chroma Key”
  • Use the eye dropper to select the green color. Adjust settings like Tolerance if needed.
  • Keep fine-tuning until only your foreground subject is visible, removing all traces of green.

Use features like spill reduction to fix any green spill on your subject. Add multiple chroma keys if working with multi-layered footage.

Step 4: Adjust and Finalize Your Composite

You’ve chroma keyed out the green screen, but we need to blend our foreground talent into the background realistically:

  • Use the Blend tool to composite your subject seamlessly into the environment. Play with Layer Modes like “Screen” or “Overlay” to make it look natural.
  • Add video filters like Color Adjustments and Shadows to match skin tones and lighting conditions with the background footage.
  • Use Layer Positioning to realistically integrate your subject into the scene, like adding parallax movement or depth-based perspective.

Keep making minor tweaks until your composite looks as realistic as possible. Watch the video preview to see the final chroma key effect.

Pro Tips for Best Green Screen Results

Here are some additional pro tips to help you master green screen editing in KineMaster:

Use the highest resolution footage possible for both your green screen clips and background videos to allow for proper keying and compositing. Shoot in landscape orientation.

Use additional lighting on your subject to evenly illuminate them separate from the green screen lighting for the cleanest key.

Minimize shadows on your green screen and subject by positioning fill lights and adjusting ISO or aperture settings when shooting.

Record a few seconds of just the green screen to use as a background plate for perfect color sampling. Exclude your subjects.
