The swarming bee phenomenon is not the result of using 720p instead of 1080i 
or p.  The cloud of bees that surrounds objects (like people's heads) as 
they move across the screen is the result of bit starvation of the codec.

Encoding the same material at 1080p 4:4:4at the same overall bitrate would 
result in more clouds of bees, not fewer.
