Macroblocking is one artifact.  But I would also consider the extreme soft 
areas as an artifact as well.  Such as when there is no detail in water 
splash (such as water polo, butterfly, etc.).  In fact, the softening can 
be so bad that objects completely disappear.

And there may be little to no macroblocking at times in the high motion 
areas, but it is also extremely blurry, such as twisting dives and 
sprinter's legs.  This is probably just blur from slow shutter speeds and 
not actually a compression artifact.

...Last night, I stood up close during a running portion of the 
decathelon.
Even the runners' legs were not macroblocking. I was amazed.

Before this, I inspected close up the high platform diving.
Macroblocking was a real issue only during the twisting and
summersaulting part of the dive, high up. When the diver was initially
running down the platform, and after straightening out to get ready to
hit the water, the macroblocking was either much less noticeable or not
there....
