After filming the white disks spinning on green screen, I realized that “green” is not actually the best color to film on top. The colour reflects on the white surface, so it makes the footage useless for keying in AF.
So I have filmed on black, which is the best background to contrast the figure in this case. However my idea about spinning hearts starts to dissipate. It doesn’t work as I expected and I think I can make mi idea to work in a better way.
