Filmmaker Julian Tryba, founder of Alinia Media, adds another dimension to conventional time-lapse with a technique he calls “layer-lapse” — conventional time-lapse videos are altered using After Effects scripting techniques to break down the cityscapes into individual buildings, allowing the time of day portrayed in each frame to vary on a building-by-building basis. The After Effects scripts can hook into triggers, allowing some of the effects to be synchronized to musical beats. The result is “a combination of mathematical and manual animation,” Tryba says, but he hopes to eventually have all of the layer animations assigned by scripts, relying on musical characteristics, human interaction, or other stimulus.  More tech info on the shoot is available at the Alinia website.
