What is chroma subsampling?

What is Chroma Subsampling? 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. A video signal is split into two different aspects: luminance information and color information.

Is chroma subsampling good?

Color information, chrominance or simply chroma is important as well but has less visual impact. What chroma subsampling does is reduce the amount of color information in the signal to allow more luminance data instead. This allows you to maintain picture clarity while effectively reducing the file size up to 50%.

What is the best chroma subsampling?

Answer: 4:4:4 is uncompressed and therefore provides the best image quality, whereas 4:2:2 and 4:2:0 sacrifice color quality for a lower data rate. Chroma subsampling is a type of color compression that reduces data rate and file size.

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.
