Wearable devices and ambient displays need to atomize video to evocative excerpts as glanceable as a still image. Glyph is a web-based tool for generating expressive GIFs from video. The tool integrates scene detection, video stabilization, video manipulation, and loop detection into a simple, web-based authoring interface. Glyph allows for creating GIFs from video with more editorial control than just choosing a clip's start and end time�diminishing some regions of movement in the clip, and highlighting others; erasing a jarring jump between the start and end of the GIF; imbuing a still image with just enough dynamism to hold our eyes and pique our interest. The result is a subtle, dynamic moving image that's lightweight, transmissible, and immediately engaging.
