Just saw this online. I love this stuff and I'm pretty good at spotting fakes having attempted much of the same effects. But Jesus Christ. This one's pretty damn good.
The motion blur, the motion tracking, the sound. Really it's that motion tracking that I find impressive. When the camera moves it's completely natural. Something I only got right at the tail end of my "glowing orb" video here.
Working on this type of stuff on no budget, is really kicking me in the ass. But fun.
