The document provides notes from research on short time-based media works. It examines characteristics of two 15-second films found on Vimeo and YouTube, such as shot length, number of cuts, camera work, and use of sound. Key elements for 15-20 second films are identified as immediate understanding through camera movements, focus, framing and use of diegetic and non-diegetic sound. Examples of potential story ideas for a 15-second film are provided, such as making a cup of tea, travelling to college, and tidying a bedroom within a tight timeframe.
