Didée gave you the solution last time
# Move the chroma Up:
crop(0,0,0,-6).pointresize(width,height,0,0,width,height).mergeluma(last)
pointresize(width,height,0,6,width,height).mergeluma(last)
But it's not perfect with that crappy video once it is deinterlaced with nnedi3 i think i know why only U or V is concerned with the chroma misplacement, let's wait for Didée
