# Image Buffer YCbCr Matrix Constants

Constants that indicate the type of conversion matrix Core Video uses when it converts image buffer data from the YCbCr color space to the RGB color space.

## Overview

Overview Use the kCVImageBufferYCbCrMatrixKey key to attach one of these values to the image buffer.
