Bitrate per pixel

[Tanos]

After some basic maths* I found out why 1080p looks so much better (at least for me eyes).

4k@60MBPS: 1 pixel gets 7.23bits per second [ (60*10^6)/(3840*2160) bps/pixel ]
1080p@40MPBS: 1 pixel gets 19.29 per second [ (40*10^6)/(1920*1080) bps/pixel ]

That's a x2.66 times more information per pixel per second.

It seems that for a busy aerial shot at 4k there is not enough bitrate. The results are visual artifacts, noise and color degradation. At the end of the road I think that the extra pixels for a better resolution provide a lower result. That's my opinion though.

Do you think it is possible to get a little more bitrate for 4k , at least at the limits of the SD card.
Also it would be nice if we could get 1080p@60MPBS and 2.7k@60MBPS

If you record at the higher resolution then downsize and render with the more sophisticated software you can set a higher bitrate.
I aren't sure that's as good as recording with high bitrate per pixel to start with though

Unfortunately artifacts will remain artifacts
