x262 hangs and produces a 0 KB file if intrinsics are turned on

This is the Avisynth Script: Code:
FFVideoSource("D:\Masterfiles\Mortal Kombat DNxHR HQX UHD BT2020 HDR HLG YUV422 25p 12bit.mxf") ConvertYUVtoXYZ(Color=0, HDRmode=2) ConvertXYZ_Reinhard_HDRtoSDR(exposure_X=2.1) ConvertXYZtoYUV(pColor=0) Spline64ResizeMT(1920, 1080) ConvertBits(bits=8, dither=1) Converttoyv16(matrix="Rec709", interlaced=false, chromaresample="Spline64") The Avisynth Script doesn't matter, though. This makes it hang just as fine: Code:
ColorBars(1920, 1080, pixel_type="YV12") Converttoyv16() ChangeFPS(25) Surprisingly, this makes it produce 1 frame: Code:
ColorBars(848, 480, pixel_type="YV12") Converttoyv16() ChangeFPS(25) EDIT: Found the bug It's the assembly part that is written incorrectly. Disabling intrinsics make it work. In other words, adding --asm 1 makes it work correctly: Quote:

I think I ran into this issue as well
Regarding your AviSynth script, wouldn't it be better to go to 4:2:2 first, then dither down to 8 bit?
