MPEG-2 is aged,inefficient and storage hungry.It is early ’90s technology.
MPEG-4 AVC/H.264 is much more efficient and supports up to studio quality 4:4:4 chroma(color) subsampling and up to 14 bits per color;it even has a lossless compression option(under High 4:4:4 Profile) in cases storage/bandwidth are no issue,e.g. for studio archiving.
At roughly the same Mbps MPEG-2 offers 4:2:2 colors H.264 can offer 4:4:4,i.e. the double color depth.Or quadruple of what the MPEG-2 4:2:0 profile provides.
I wonder whether the continuing MPEG-2 legacy is due to compatibility issues or designing/licensing costs..
