Craig,
I couldn't disagree with you more.
Far from being ludicrous, adding 1080p60 to MPEG-2 makes sense to me.
MPEG-2, at higher bitrates and 4:2:2 color space, is a relatively benign way
to encode material for editing and other manipulation before ultimate
emission.
MPEG-4, especially if the full toolkit is used, not just the basic level
that is used for videoconferencing and those cheapie "H.264" internet
encoders, makes for a good one time encode for emission, but is not suitable
for multiple "passes" in the typical production process
MPEG-2 1080p60 4:2:2 can compete effectively with HDCam's 3:1:1 or DVCPRO
100's 4:1:1 color spaces for NLE.
Now, if you're just talking emission standards then yes, I agree it is
ludicrous.
John

Here is a prime example of why it is ludicrous to go back and update
MPEG-2 with a level to support 1080@60P.
