As photographers we constantly make creative decisions involving time and movement. We use long exposures to accentuate motion over time. We freeze time with fast exposures to capture the power of athletes in motion. Creating time-lapse video is another really fun way to visually dramatize time. It allows us to dabble in a new realm and capture the world of movement that we see around us in new and exciting ways.
Frequently students ask me if their digital cameras are capable of producing high-definition time-lapse and the answer is an emphatic yes. Film and video are simply a series of still frames played at 24 or 30 frames per second. Each frame of high definition 1080p video is only seven megapixels in size. Not only that, to keep file sizes small, digital video recording is so highly compressed that the ability to post process it is highly compromised. That means that a time-lapse created from a 14-megapixel still camera’s RAW images will be many times more editable than, as well as twice the resolution of, traditional video filmed in high definition.
FRAMES PER SECOND (FPS):
Before we delve any deeper I want to demystify the term frames-per-second (“FPS”) as it applies to video playback...Read More
