Einstein proved that time is relative. But it’s moviemakers like Conor McDonnell who allow us to see the malleability of the fourth dimension. In “100 Second Week” McDonnnell reduces a journey spanning 168 hours to 100 seconds.

Time bending in movies can be done in several ways. You can vary the frame rate to create slow motion, speeded up motion, and time-lapse cinematography. In “100 Second Week” McDonald using editing to achieve time compression. He simply creates short clips–essential moments captured at normal film rates–which he splices together.

This kind of time compression isn’t limited to movies. In the 1960s, sound artist Tony Schwartz created  “Nancy Grows Up,” a 2-minute audio production that captured the growth of his niece over a period of 13 years.

Time compression doesn’t have to remain in the domain of professional filmmakers. It’s a technique that can allow even novices to produce all sorts of memorable videos ranging from travelogues (e.g., “My Hike Up Kilimanjaro in 60 Seconds”) to instructional pieces (“How to Paint a Garage Door in Two Minutes”) to sports photography (e.g., presenting all the key plays of a football game in half a minute).
