well, the I P stands for 'I'm Pissed off' , (see the second part of my post, the interesting part...)
The B is indeed correct, also stands for Bed time for me now...

> afair, Dennis is still wrong. IMX is indeed an I frame only format, and SX is IpIpIp, hardly long GOP. For the CC comments back in the days, i think it was about 8 bits vs 10 bits, and indeed some compression that expects no-one will ever lift blacks.
I respond:
I corrected myself minutes after my initial message. SX is described as MPEG2 using a mild temporal compression, as you've described "IpIpIp" (I've always known it as "IbIbIb", but the sequence is the same, just described differently). That still makes it Long-GOP as far as I'm concerned since it is definitely NOT Intra-frame. So I guess we'll have to disagree on the semantics. In the interest of compromise, perhaps it should be called "Short-GOP" ;)
