Ok, so here's my guess: You cloned the board's fall out, then rotoed the board, then repeated the same step a couple of time, only keeping the board. Then you stitched them all together, and adjusted the timing of the last clip to align the rotating phase of the composited board and the landing one. I'm just baffled by how smooth this was, though. I had to go down to 1/4 speed to make any sense of it, and I don't really have any evidence that what I said was right, it's just what I would've in trying to replicate it. Might be a 3D model for all I know. How this only has 2.9K views is even more confusing, and Mr.Weebl truly found the right channel to promote!
I thought that at the end that the board would just snapto your feet but no, i went frame by frame and it actually smoothly looked like you landed on it! nice editing!
Oh my god, I love finding awesome stuff before it becomes truly internet famous. It's really interesting to watch someone's path through RU-vid. You have only one video which could be considered viral, but I'm 100% sure that's going to change and I'll be here to see it! TLDR: You sir, have a new subscriber :D
Technically this is possible though wind thrust it would have to go much faster though and have a small weight that slides around the board evening the board
