In a linear timelapse, the gap between each photo is the same (So; take a photo every 2 seconds, for example). This gives the illusion of something happening at high speed.
This video shows two 'eased' timelapse clips. The clips are not sped up or slowed down in post production. Instead, we are using the Triggertrap to vary the gaps between each photo. As a result, the animation in the timelapse appears to 'speed up' and 'slow down'.
The video shows two different acceleration profiles: x^2 (Quadratic) and x^4 (Quartic). Triggertrap supports 15 different modes: five different acceleration profiles (sine, quadratic, cubic, quartic and quintic), with the choice of easing into, out of, or in-and-out of the timelapse set.

This film was shot in two weeks (Dec '13) on the Hawaiian islands of Oahu and Maui. Many of the timelapses were taken on Haleakalā (House of the Sun), which is a 10,000ft tall dormant volcano. The volcano is a timelapse photographers dream; the climate is in constant flux and the landscape is absolutely breathtaking. I often spent 12 to 15 hours on the mountain watching the clouds and photographing them. The trip was exhausting but it made me happy knowing I was doing what I love.
It was one hell of a journey during the fourteen months making Wyoming Wildscapes II, my second and final (maybe not!) Wyoming related time lapse project. Had plenty of adventures while working on this. Lightning almost got me a couple of times this summer, gear froze up in the winter (literally), and broke a few times (don't think most of the time lapse gear was meant for extended wilderness backpacking), all that fun stuff. Despite any minor set backs, this was without a doubt one of the most fulfilling personal projects I've ever undertaken. Saw some pretty amazing stuff along the way, this part of the country never ceases to amaze and surprise me.
