First - i need resize, cause uspp is blurry, but with 1,5x resize and 
resize back after i get nice edges what can be easly and safly 
msharpened, btw resizing in yv12 give bad results, so i want resize in rgb24
In end i use editor video what will use rgb24 so rgb is at end
But my question was about uspp , i tryed 444P cause it have yv12 
structure, but don't know if only adding case of other colorspace at 
input can help with quality filtering

PS. uspp in ffdshow use yv12 or similar colorspace, so it is the same as 
in mencoder
