This is a video created by Esteban DiÃ¡cono to the music of Olafur Arnalds' LjÃ³siÃ° using "Adobe After Effects, particular v2, soundkeys and a little starglow". It's basically a bunch of smoke dancing around. But not like that shit in Lost!
i first imported the audio and set up 2 sounkeys layers, one for the piano and one for the strings. Then i worked the particles and the particle subsystem and linked things like the emission, the turbulence, the velocity, the spin amplitude and the strenght of the fields to the soundkeys outputs. Then i set up the colors with 2 different palettes, and well, after that there was a lot of trial and error in order to achieve what i was looking for. There's a lot of randomness involved in here, so there was also a lot of luck, of course.
I don't really understand any of that, but what's new? The important thing is that you just got paid for watching a three and a half minute video at work. High five!
Thanks to Andrew, who once inhaled some of that smoke and got all high as a kite and forgot to catch the bus.
