Elastic Video is a variable-speed time lapse camera that adjusts the frame rate based on the amount of change in the video -- automatically combining time-lapse and standard video recording in one application. When there is less activity, frames are captured less often so when they are played back those portions of the video move quickly. As the amount of activity increases (e.g., objects entering, leaving or moving around), the frame rate increases so that on playback those portions of the video are played back at a normal rate.
Applications include event detect, video summarization, and video frame rate compression.
A time history graph at the bottom of the screen plots the amount of detected change as a function of time. For best results the device should be held against a fixed surface to minimize movement. The slider adjusts sensitivity to device motion and scene change.
To dramatize the operation of the app we recorded water dripping from a leaky faucet. Here's the app recording the drip
On playback notice how the clock speeds up in between drips.
The app is designed to detect and record significant changes in video skipping sections between events that have little or no activity.
In this example a 3 minute video of fishing swimming in a tropical lagoon is compressed more than 10X to about 16 seconds.
