During lockdown, I collaborated with Hannah Rose Kessler, Ksenia Kulakova and Bethan Thorsby on a video for Hannah’s new single, ‘I Really Wanna’. We put out a call for recordings of friends and fans dancing to the song, and collected them together for the video. I was responsible for the dancing colour overlays – a way to ground everyone’s videos in one visual style. I used expressions in After Effects to automatically tie the movement of the overlays to the movement in the video beneath, and their brightness to the sound of the music.
