Homework

This week the teacher talked about how to further process the green screen material, for example, we can use SpillReplace to do smoother processing of the colors.

We can also use constant to select specific colors in the video, which facilitates better editing.

Then it also introduces the simple method of deducting the blue screen

First of all, I first used keylight for deduction, but the processing of hair is not satisfied, after using SpillReplace for color processing, the effect is much better. After that, I used blur to process the edges, and then the alpha layer of the character was processed. Copy the alpha layer to the image and combine the background with the character. Finally, the whole job is finished with color mixing. After that, the background was resized so that the video had no black edges.
