In video encoding, what does 'Chroma' represent?

Chroma refers specifically to the encoded color information in video encoding. This term encompasses the attributes of color, including hue and saturation, distinguishing it from luminance, which represents brightness. In video and image processing, understanding chroma is essential for accurately conveying the full spectrum of colors in visual content.

Luminance, which is often represented by the term 'y', conveys how bright the image is but does not provide information about the colors present. The total number of pixels indicates image resolution and is not directly related to the color information itself. Frame rate pertains to how many frames are displayed per second and is unrelated to the color encoding aspects of a video signal.

Thus, the understanding of chroma as the encoded color information is fundamental in video encoding as it contributes significantly to the overall aesthetic and perception of the visual media.
