the bitrate is loss control when encoding 4096x2160 + hevc
hi, i use SvtHevcEncApp to encode a YUV file with -w 4096 -h 2160 , but it seems that -tbr parameter is not working. I used the cmd below, can anyone give me any suggestions to solve this problem?
sgui@sgui-gpu /mnt/work/source/SVT-HEVC/Bin/Release $ sudo ./SvtHevcEncApp -i /mnt/tmp/test.yuv -w 4096 -h 2160 -rc 1 -tbr 8192000 -fps 50 -b testbuilding4k4096.265 [sudo] password for sgui:

if i use cmd like： ./SvtHevcEncApp -i /mnt/tmp/test.yuv -w 3840 -h 2160 -rc 1 -tbr 8192000 -fps 50 -b testbuilding4k3840.265
the bitrate is correct

Hello @a3213105 , Have you tried building SVT-HEVC on bare metal? If so, do you see same results? Is this issue specific to the OVC Dockerfile container?
hi @dpatel257 , i have build and tested SVT-HEVC on a bare metal Windows server, and I have not tried on the OVC container yet. I will try to test on the container to check if the same issue will be reproduced.
