Stock clips of surreal visualisations, space time-lapses, static glitches and macro shots of colour changing glitter balls were then placed in the layer below to finish off our desired effect.
Keying Out
Now that the footage was edited in Premiere Pro I then imported the project into After Effects to begin the process of keying out the green parts. The first step was to apply a colour balance effect to each clip and reduce the amount of green in the highlights in the backdrop to ensure a cleaner keying. I then used Keylight 1.2 as before to remove the green parts we needed to, with a slight adjustment on the black and white clipping levels to clean things up.
