Do note that you actually need significantly more optical resolution to get a good picture at specified resolution.
In other words, a 1080p camera, generally, can't really get *true* 1080p quality.  Of course, lens probably matters more etc, but, well, yeah...

And, so, the video should be downscaled (not left at original resolution).

I still see a lot of 8MP still cameras being sold, so it's going to be a long long time before consumer grade video recording equipment gets anywhere near that resolution >_>
