Time Manipulation With Twixtor

This music video contains some of the best post production editing I've seen in a long time. The video was filmed at half speed, maybe less, and then it was sped up and slowed down using 'Twixtor' an application allowing you to alter the speed of footage even if it was not filmed at a high frame rate. The quality of editing is very high as we see it keeping in time with the fight scenes keeping in time with the beat of the music consistently throughout.
