Chroma 4k-> 1440p? 4:2:0 -> 4:2:2?

[LucasHoller]

Hey smart people, there are somthing i have been wondering for a while. It have been established and widely accepted that downscaling/upsampling 4k to 1080 result in a 8bit 4:4:4 image, but does this work for 1440p aswell? Will a 4k image upsampled to 1440 result in a 8 bit 4:2:2 image? Logiclly it makes sence by comparison to the upsampling for the 4k to 1080p but i dont think i trusty own logic in this case ? So what do you think? And just a bounus question: if yes, could you make a 4k 4:2:2 image to a 1440p 4:4:4 image with the same logic? 

 

Thanks. I know its a complicated debate but i wanted to hear your oppinion.

No doesn't work the vertical resolution has to be at least 2x  smaller.
