2D films are traditional movies that display images in two dimensions, meaning they have height and width but no depth. These films are typically viewed on flat screens, such as those in theaters or on televisions. The visuals are created using a series of still images that are projected in rapid succession, creating the illusion of motion. The most common format for 2D films is standard film, which uses a rectangular frame to capture scenes. Unlike 3D films, which require special glasses to perceive depth, 2D films can be enjoyed without any additional equipment. This makes them accessible to a wider audience.
