Slow is a relative term, on a modern computer it shouldn't take more than a msec to transpose a SD yv12 frame from cache even with the naive C implementation in Avisynth (on mine it takes nearly 2, but that stuff ain't modern). Just a drop in the bucket really.
A bigger problem to me seems that processing U/V planes without data from the Y plane is a bit dodgy.
