On additional source of problems:
You are using 32bit Avisynth, which will run out of memory, with 8 threads on 4k resolutions.
Without any deinterlacing just Interframe on a 4k Source will probably kill the ~4GB max memory that 32bit can use. (especially if everything runs through the cpu and multiple threads are used)
Switching to 64bit Avisynth, should help with the speed and might also help with memory restriction.
Regarding speed: enabling GPU support with Interframe also might help.

Ps.: at least here Vapoursynth is way faster with 4k content.
