One is display aspect ratio or DAR this is the ratio most commonly referred to by the term "aspect ratio", and is the ratio of the video frame's physical (displayed) width to its height, regardless of the number of pixels used to represent the video image. There are two types of aspect ratios involved in video editing. Another advantage of Y'UV is that some of the information can be discarded in order to reduce bandwidth. The primary advantages of luma/chroma systems such as Y'UV, and its relatives Y'IQ and YDbDr, are that they remain compatible with black and white analog television. ‘Y’ stands for the luma component (the brightness) and U and V are the chrominance (color) components luminance is denoted by Y and luma by Y'.Y'UV signals are typically created from RGB (red, green and blue) source.
