Video provides a better representation of a crime scene than sketches or photographs as it gives the viewer a feel for how the scene appeared and allows them to view the scene's layout and evidence relationships similarly to experiencing it in person. An effective crime scene video is produced by slowly and methodically recording establishing shots of the entire scene and then closer views of individual evidence while considering camera positioning, movement speed, lighting, and audio quality. The video serves as an objective documentation of the scene and can be used later to refresh memories or as demonstrative evidence in court.
