Ah… excuse me but there is no CCIR standard for JPEG, and while comparing ratios you're not taking into account differences in encoding schemes, which makes your comparison of 4:1:1, 4:2:2 etc. with JPEG basically irrelevant. And just so you know, the proposed standard for JPEG offers data compression of between 10 and 100 times with three levels of processing defined, the baseline, extended and lossless encoding. So even if your analogy was accurate the JPEG encoding scheme employed by 3DS would easily conform. PMJI Gary. John
