Between 7900x and 1950x you can only buy one processor and that is of course 1950x or 2950x that will be released at Q3 2018.

The overall difference, as you already know, is huge favoring 1950x especially on rendering/ encoding and AVX512 is nonsense, pure nonsense for almost any task for desktop or even workstation.

You need 6 channel or 8 channel DDR4 or maybe DDR5 (2019/2020) to leverage effectively AVX512 and water cooling in most cases.

Let's forget AVX512 for the next 5 years for desktop and workstation.
Unless we're talking strictly about encoding material with > 1080 vertical resolution or running multiple encoder instances simultaneously, Threadripper is is pretty much the worst possible choice for HEVC encoding you can currently get.

Skylake-X has > 50% IPC advantage in the most recent encoder version over Ryzen, due to AVX2 (+41.7%) and AVX512 (+6.1%). Obviously Skylake-X is expensive and the power consumption is rather brutal, but regardless for typical end-user scenarios you're better basically with anything else than Threadripper. On a budget used MCC or HCC Haswell-EP CPUs are probably the best way to go.
