  2. Split that into two command lines at the second ffmpeg.exe
    Code:
    ffmpeg.exe -probesize 50M -analyzeduration 100M -fflags +genpts -i "d:\tmp\test.mkv" -pass 1 -passlogfile "d:\tmp\test.TStestlog" -fastfirstpass 1 -an -map 0:0 -map 0:1 -c:v libx265 -r 25 -aspect 16:9 -pix_fmt yuv444p -preset fast -x265-params profile=main444-8:crf=25:me=hex:scenecut=40:bframes=4:min-keyint=25:keyint=50 -qmin 3 -qmax 51 -qdiff 4 -qcomp 0.6 -vtag hvc1 -metadata creation_time=now -af dynaudnorm=f=500:g=31:p=0.95:m=10:b=1:s=0 -vf scale=iw*sar:ih,crop="min(iw\,ih*(16/9)):ow/(16/9)",scale=1920:1080 -sn -aspect 16:9 -f rawvideo -y nul && ^
    ffmpeg.exe -probesize 50M -analyzeduration 100M -fflags +genpts -i "d:\tmp\test.mkv" -pass 2 -passlogfile "D:\tmp\test.TStestlog" -map 0:0 -map 0:1 -c:a aac -ab 160k -strict -2 -async 1 -c:v libx265 -r 30 -aspect 16:9 -pix_fmt yuv444p -preset fast -x265-params profile=main444-8:crf=25:me=hex:scenecut=40:bframes=4:min-keyint=30:keyint=60 -qmin 3 -qmax 51 -qdiff 4 -qcomp 0.6 -vtag hvc1 -metadata creation_time=now -af dynaudnorm=f=500:g=31:p=0.95:m=10:b=1:s=0 -vf scale=1920:1080 -sn -y "D:\tmp\test.TStest.mp4"
