SMPTE Standards

Definition

SMPTE Standards are a set of technical specifications developed by the Society of Motion Picture and Television Engineers to ensure interoperability and quality in the fields of motion picture, television, and digital media. These standards cover various aspects, such as image and audio formats, color representation, and signal processing, which are essential for high-quality production and distribution. They play a crucial role in the implementation of High Dynamic Range (HDR) cinematography, helping creators achieve vibrant visuals with a broader range of luminance and colors.
