1) Double the chroma from 356x240 to 712x480.
2) Double the Luma from 712x480 to 1424x960 then double again to 2848x1920 then downscale with Catmull-Rom AR to 1920x1080.
3) Double the chroma from 712x480 to 1424x960 then double again to 2848x1920.

Is this correct? Doesn't this mean that the end result has different chroma and luma resolutions?
The first chroma entry is for chroma upsampling from 4:2:0 to 4:4:4. The second chroma entry is for chroma upscaling for matching the chroma to the luma upscaled resolution. I believe that's correct but if not fell free to correct me anyone.
