New Hybrid install on Windows 11

[Selur]

Does the Vapoursynth Preview work?

Does calling:

"C:\Program Files\Hybrid\64bit\Vapoursynth\Lib\site-packages\vapoursynth\vspipe.exe" "P:\Hybrid-TEMP\encodingTempSynthSkript_2026-05-21@13_09_25_8510_0.vpy" - --outputindex 0 -c y4m | "C:\Program Files\Hybrid\64bit\ffmpeg.exe" -y -noautorotate -nostdin -threads 8 -color_range tv -f yuv4mpegpipe -i - -an -sn -color_primaries bt709 -color_trc bt709 -colorspace bt709 -color_range tv -pix_fmt yuv422p10le -strict -1 -fps_mode auto -r 24000/1001 -vcodec prores_ks -profile:v 2 -vtag apcn -metadata encoding_tool="Hybrid 2026.05.20.1" -aspect 1280:720 -f mov "P:\Hybrid-TEMP\Arielle Dombasle 2398 drop_1_2026-05-21@13_09_25_8510_03.mov"

produce any errors?

seems fine and from the looks of it, either ffmpeg crashes or Hybrid crashes analyzing the output ffmpeg,...

Is this reproducible? If it is, can you share a sample of a clip that allows to reproduce the problem?

side note:
unless your source is progressive content that was created from interlaced content that got resized and encoded progressively without deinterlacing:

# resizing using NNEDI3CL
# current: 640x360 target: 1280x720
clip = edi_rpow2.nnedi3cl_rpow2(clip, rfactor=2, nns=4) # 1280x720

is probably a bad idea.
