What is the best Bitrate for UHD 4K encoding in H264?

[Emilio Le roux]

Oh! of course, sorry.
So theoretically one would multiply bitrate by four to get about same quality, if compared to Full HD?

And as you can’t have interlaced UHD some UHD content is double framerate. 50P here in the UK for sport.
So 8 times the content.

That’s why H265 is more suitable. Half the file size for the same quality.
But the maths don’t quite work as a linear expiration for H264. You will find the codec becomes more efficient as the data rate goes up.
I’d experiment and then add 10% to what seems artefact free.

I read that professionally they do 4K in a bitrate of 16000. Frame rate of 30, 50 or 60! Audio part I don’t know, but I put it on 48 from 44. When I burn mp3’s I use 48, it makes the sound more fuller
