I must be missing something. It appears that the OP in the link, is direct comparing a 6000x4000 still with a 1920x1080 video frame

You are. He clearly stated that he downscaled the still and used that to compare to the single video frame.

I think the point is that the process he used for the downscaling is better than that used by the video system, and so it should be, as it is not constrained by processor capacity or time.

I think you're right in that part of it is in the downscaling and sharpening done on the computer is better than on the fly.

The other part is that the A77 isn't outputing uncompressed video, it's all in H.264 in the AVCHD file.  Videos are not simply a collection of still images.  Even using some kind of a key frame involves reconstruction of the image, so it's not 100% the same as dealing with the still.
