How to Adjust Chroma Key Similarity and Sensitivity

Similarity and sensitivity determine which background pixels are removed and how cleanly edges appear.

Before you begin

Check that your device and installed Live Now version support the feature. Available controls and labels can differ by iOS, Android and app release.

Steps

  1. Enable Green Screen.
  2. Select a preset key color or use the color picker.
  3. Increase similarity gradually until the backdrop disappears.
  4. Adjust sensitivity to preserve hair and clothing edges.
  5. Check the result under your actual lighting.

Tips and limitations

Excessive similarity can erase parts of the subject. Use even lighting and separation from the backdrop.

Support

If you need assistance, share your device model, operating system, Live Now version, and a short description or screen recording of the problem with the Live Now support team.
