When I try use check "Prefer FFmpegsource" the encode not working.

Avisynth preview error: -> ConvertToStacked: Input clip must be native 16 bit: YUV420P16, YUV422P16, YUV444P16, Y16 (K:\temp\tempPreviewAvisynthFile14_58_00_440.avs, line 30)

Seems like instead of YUY2, YUV422P16 should be used.
I'll build a dev version for testing.

Ps.: If that version doesn't work I'll need a sample of the source to reproduce and workaround the problem. (pm is send)

Now preview working, but very slowly - AVSviewer64.exe allocated 5gB memory

Use other settings if you think it's too slow.
Since you don't plan to stay in 16bit and 4:2:2 you could enable "Filtering->Avisynth->Misc->Source->Convert to target color space directly after the source filter", this might speed up things.

AVSviewer64.exe allocated 5gB memory

use less threads and other filters,...
