Our main content this week is green screen extraction. In the beginning, I tried to use a single picture as the material for the test. Then proceed to channel inspection. When all the steps are working, I will replace the pictures with video footage.

Regarding this footage. When I chose it, I didn’t notice that the background of this material was too flat and the color saturation was too high. When I processed it in Nuke, I found that its edges were too flat. It looked like footage that had already been processed. But I still finished it. Because I think this material is very suitable for some cool game scenes.

After that, I used two different methods to process this picture.

In contrast, the result obtained by the second method has softer edges. It may also be the result of different parameters.
