When dealing with 4x subsampling ratios (log2 == 2), such as can arise with 4:1:1 or 4:1:0, a value range of 512 is not enough to cover the range of possible scenarios. For example, bottom-sited chroma in 4:1:0 would require an offset of 768 (three luma rows). Simply double the limit to 1024. I don't see any place in initFilter() that would experience overflow as a result of this change, especially since get_local_pos() right-shifts it by the subsampling ratio again.
