FFMPEG X265 Parameter help please

[iKron]

I was looking for x265 preset option and found this page

https://x265.readthedocs.io/en/master/presets.html

i tried to add this following command but ffmpeg gave error, that this syntax is not available for ffmpeg

-limit-tu 4 -no-sao

i search on ffmpeg site for the x265 parameters, but could not find any useful. can someone guide me or give me any page link from where i can see the x265 parameters?

In general, most switches in x265 are reflected in ffmpeg libx265 using x265-params using key1=value:key2=value...

It would look like this

-x265-params "limit-tu=4:tu-inter-depth=2:no-sao=1"

In order to use --limit-tu 4, the tu-inter-depth has to be >1
