Does chroma sampling affect bandwidth?
Chroma subsampling is a type of compression that reduces the color information in a signal in favor of luminance data. This reduces bandwidth without significantly affecting picture quality.
How does chroma subsampling reduce bandwidth?
Chroma subsampling involves the reduction of color resolution in video signals in order to save bandwidth. The color component information (chroma) is reduced by sampling them at a lower rate than the brightness (luma).
How does chroma subsampling reduce the size of a video stream?
By reducing the amount of color information in a video signal to allow more luminance data instead, chroma subsampling allows picture clarity to be maintained while effectively reducing the file size by up to 50%.
Does chroma subsampling reduce resolution?
Chroma subsampling is the practice of encoding images by implementing less resolution for chroma information than for luma information, taking advantage of the human visual system's lower acuity for color differences than for luminance.
