 away, and you changed your command line: add scaling and BRC modes:

 > 1. Have you tried HEVC HW encoder,what is the result?
 > 2. Why you change BRC mode from CQP to AVBR and add scaling? Dose CQP
 mode can work?
 > 3. Have you tried HEVC SW encoder with MSDK sample encoder?
 > 4. Try to figure out it is an qsv vpp issue or encoder issue. You can
 disable encoder and check the output of vpp.
 1 - Yes i have tried HEVC HW Encoder and it Works but when try software
 encoder the final result are garbage of colors, it seems something is
 wrong with ffmpeg
 2- Sorry for that but doenst matter what BRC i use, CQP-AVB-VBR on HW it
 Works but software is garbage, can u address this bug to ffmpeg developers
 to fix this issue? This Works on sample_multi_transcode on Windows 10 Pro
 x64 with git Media SDK
 3- Yes sample encoder Works but i use alot ffmpeg right now
 4- OK i will try and send feedback to you
