8K video was automatically transcoded to 1080p in NVENCC,it crashes in FFMPEG Version

[Selur]

And since you did not read the sticky and didn't provide any information for me to reproduce this I don't know how I could help.
as a side note: "HEVC encode with weightp is known to be unstable on some environments."

Tested on my current system:

ffmpeg -y -loglevel fatal -noautorotate -threads 8 -i "C:\Users\Selur\Desktop\paloma8kprores.mov" -map 0:0 -an -sn -vf zscale=rangein=tv:range=tv -pix_fmt yuv444p10le -strict -1 -vsync 0  -f yuv4mpegpipe - | NVEncC --y4m -i - --fps 24.000 --codec h265 --profile main444 --level auto --tier high --sar 1:1 --lookahead 32 --output-depth 10 --cbrhq 44000 --max-bitrate 240000 --aq --gop-len 600 --strict-gop --bframes 4 --ref 7 --weightp --mv-precision Q-pel --cu-max 32 --cu-min 8 --preset quality --colormatrix bt709 --cuda-schedule sync --output "E:\Temp\paloma8kprores_13_36_54_1210_02.265"

and got:

Max B frames are 0 frames.
HEVC encode with weightp is known to be unstable on some environments.
Consider not using weightp with HEVC encode if unstable.
Failed to cuMemAllocPitch, 2 (cudaErrorMemoryAllocation)

When using: (removed the cu-settings)

ffmpeg -y -loglevel fatal -noautorotate -threads 8 -i "C:\Users\Selur\Desktop\paloma8kprores.mov" -map 0:0 -an -sn -vf zscale=rangein=tv:range=tv -pix_fmt yuv444p10le -strict -1 -vsync 0  -f yuv4mpegpipe - | NVEncC --y4m -i - --fps 24.000 --codec h265 --profile main444 --level auto --tier high --sar 1:1 --lookahead 32 --output-depth 10 --cbrhq 44000 --max-bitrate 240000 --aq --gop-len 600 --strict-gop --bframes 4 --ref 7 --weightp --mv-precision Q-pel --preset quality --colormatrix bt709 --cuda-schedule sync --output "E:\Temp\paloma8kprores_13_36_54_1210_02.265""

I get:

y4m: failed to parse y4m header.
Failed to open input file.

-> seems like NVEncC has a problem with yuv444p10le input (opened an issue entry for Rigaya: https://github.com/rigaya/NVEnc/issues/127)

using:

ffmpeg -y -loglevel fatal -noautorotate -threads 8 -i "C:\Users\Selur\Desktop\paloma8kprores.mov" -map 0:0 -an -sn -vf zscale=rangein=tv:range=tv -pix_fmt yuv444p10le -strict -1 -vsync 0  -f yuv4mpegpipe - | NVEncC --y4m -i - --fps 24.000 --codec h265 --sar 1:1 --output-depth 10 --cbrhq 44000 --max-bitrate 240000 --colormatrix bt709  --output "E:\Temp\paloma8kprores_13_36_54_1210_02.265"

encoding seem to start,..
