Wow that’s a creative video!
My guess would be a lot of time and patience? lol
I believe it would be possible to do 90% of this video with a printer, a cheap video camera, a still camera. Film your talent doing their moves, print the frames you need for motion, cut them out and then film the whole thing as 10cm tall miniature cutouts…
Or
It looks to me like this could have been filmed and assembled without a green screen… because all the “actors” are cutouts it looks like they could have used white to fit the paper theme.
After you have your video cut out, probably a rotoscope or a even just an angular junk matte.
Looks like they’ve taken the same cut out and layered time after time, offset the time of some of the cutouts, freeze some while other continue, and obviously run them all in 3d space.
You very seldomly see any of the 3d layers straight on its edge so its possible they are just simple flat 3d layers in After Effects. Even when the images fan out, or the camera spins around, and you do see and edge its so fast its hard to tell if there is true thickness to them.
Either way, or neither way, it was a lot of work, but it paid off… unique feel, great look. I like it, thanks for showing me =)
