This week I started to process the green screen footage that I shot. And trying to composite some of the footage.

For the portal shots, I mainly tracked the whole video. The portal is then made to follow the movement of the camera. Afterward I also created shadows for the portal. And the colors were adjusted for the portal.

Regarding the handling of green screen material. I mainly use the keylight node for green screen keying.

After that, I copied a video for color grading and adjustment. Went to create a shadow for the main video. To make the whole video look more realistic.

I still have some hesitation about the choice of background. At first, I wanted to make a void scene myself. But for reasons of time. I then found video footage of smoke and stars on the internet. I used these two clips for color grading to create a virtual space.

Next week I will be putting the remaining videos through their final compositions.
