It would be easier, and what would be the point of generating a 1920 hrz rez frame knowing it's going to be reduced to 1280? This format would never be used, there is already a 720 3d format! To me what they are doing is sort of interlacing, one frame holds 2 1080x540 frames, they are stretched to 1920x1080, In effect your getting 1920x1080 left and right frames updated every 1/60 sec. The frames are subsampled to 540 vertical, and then stretched to 1080, but at 60hz rate per stereo frame, it's an averaging interlacing, or at least that's what i'd call it. |
lol. You are much more accurate with resolution definitions than me.
I believe 1080i per eye resolution is what you have in mind and its absolutely correct.
I tend to keep it simple and deal with 480p, 720p, and 1080p when I talk. 1080i is roughly the same amount of pixels as 720p and visual quality of both to the human eye is about the same... hence I don't distinguish the two.
But you are right...1080i not 720p. My bad.
