Need help in Ultrakey setting for removing green screen

[Shreya_Chaturvedi5644]

Hi,

This is my edited video: https://limewire.com/d/9zwck#328fAJNhVv

Original video is recorded with a green screen background in behind and I edited using premier pro and ultrakey setup.

If you see back of my top head near hair, it is still flickering and anybody can figure out that green screen thing did not work perfectly. Can you please suggest what  I can do to make it look better. Please give clear input/steps of setup in premier pro to overcome this. I am also sharing images with my settings if that help you to gauge what I did wrong. Thanks in adavance!

Try the following steps to improve your green screen keying with Ultra Key:

1. Use an Opacity Mask First: If your subject doesn’t move much, apply an opacity mask to crop out unnecessary parts of the background. Then, fine-tune your Ultra Key settings. This reduces the keying workload and allows for more precise adjustments.
2. Lower the Contrast: In the Ultra Key effect, reducing the Contrast setting can help soften edges and eliminate harsh artifacts.
3. Refine the Lumetri HSL Secondary Mask: If you’re using Lumetri Color to grade your green screen, go to the HSL Secondary tab and increase the Blur and Denoise values. This helps smooth the mask and reduce noise around your subject.
   
   

These adjustments should help you achieve a cleaner key with smoother edges and fewer visual issues.
