126 What is the best compression ratio for MPEG ? (MPEG-2)
The MPEG sweet spot is about 1.2 bits/pel Intra and 0.35 bits/pixel
inter. Experimentation has shown that intra frame coding with the
familiar DCT-Quantization-Huffman hybrid algorithm achieves optimal
performance at about an average of 1.2 bits/sample or about 6:1
compression ratio. Below this point, artifacts become non-transparent.
