On this footage, I started with BCC Linear Color Key and then used Keylight to remove edges I couldn’t get out with the first key. This slowed down rendering time considerably and as there were two shots; one of the front view of the mudra and one of the back view I needed to precompose. I rendered the front and back views separately with their alpha channels intact and started a new composition using these files. The shadows were also created from these files so I had four video clips in all used in this comp.
