Playing with [Super] Slow Motion

I made this video for testing Twixtor for Final Cut Pro.
I chose subjects like skateboarding, people, shattered glass and water.
Some time in the video you might notice some artifacts, but this is the best that I could get at 60fps.

Lenses used: Canon EF 35mm f/2 – Samyang 8mm f/3.5

Shutter speed: 1000 to 2000

ISO: 100 to 400

Music: “To Build A Home (instrumental)” – The Cinematic Orchestra [Richard H]
