The format is a subset of a COS ("Carousel" Object Structure) format. [24]
Hyperlapse or moving time-lapse (also stop-motion time-lapse, walklapse, spacelapse) is a technique in time-lapse photography for creating motion shots. In its simplest form, a hyperlapse is achieved by moving the camera a short distance between each shot. The first film using the hyperlapse technique dates to 1995.
Some of the most stunning time-lapse images are created by moving the camera during the shot. A time-lapse camera can be mounted to a moving car for example to create a notion of extreme speed. However, to achieve the effect of a simple tracking shot, it is necessary to use motion control to move the camera.
Whereas time-lapses are normally produced by stitching together stills from traditional cameras, the app uses an image stabilization algorithm that steadies the appearance of video by eliminating jitter.

The MP4 file format was generalized into the ISO base media file format (ISO/IEC 14496-12:2004 or ISO/IEC 15444-12:2004), which defines a general structure for time-based media files. It is used as the basis for other file formats in the family such as MP4, 3GP, and Motion JPEG 2000). [8]
