UVD3 because of MPEG-4 decoding, right? And UVD5 because of 4K resolution, right? But why UVD4? Because of Fluid Motion? H.265 decoding starts with UVD6, btw. (and 10-bit colour depth support with UVD6.2).

I don't think video encoding (VCE/VCN for H.264, UVD6.3+/VCN for H.265) should matter before video decoding is supported.
