Video can be described as display a moving image, which is made up of many individual frames played at a fast rate. Good video is played at 30 frames per second or higher. A slower rate can begin to look choppy and affect the presentation quality.
Video content can be "live", such as previously recorded live feeds, or previously created content full-capable video displays as being capable of both live feeds and pre-produced content, whereas graphic messaging displays are only capable of pre-produced, or stored content. Many LED display applications do not require the live feed capability or complexity of these systems. The higher the level of expectation, the higher the required display capability.
Video graphical frames require high pixel counts and color depth to provide a good definition for highly detailed, accurate and recognizable images. Video clips can be small displays with minimal color depth, but the image will look abnormal and will lack definition; however, the results may be acceptable for certain applications. Color depth, or levers, is the amount of color available to portray the image. Most digital video content is 16.7 million colors but more levels of color depth are recommended to provide proper color matching to the original image. Video purists suggest a minimum of 1 billion colors for best video images.
