  1. I was looking for x265 preset option and found this page

    Code:
    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
    Code:
    -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
    Code:
    -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

    what is the input format? 8bit 4:2:0 ?

    what is the desired output format? 10bit 4:2:0 ?

    Code:
    -vf format=yuv420p10le


    Code:
    -vf format=yuv420p10le -x265-params "limit-tu=1:tu-inter-depth=1:no-sao=1"

    thank you so much, 10bit encoding working. i will use same output format of input format. i am really new with x265. this is my current x265 encode settings i am trying. kindly let me know if i adding all command good and if need to add something extra or remove extra to make the encode better let me know please.

    Code:
    -vf format=yuv420p10le -x265-params "ref=6:deblock=-3:-3:limit-refs=1:limit-tu=1:tu-inter-depth=4:tu-intra-depth=3:psy-rdoq=1.1:aq-mode=3:subme=5:merange=64:bframes=8:max-merge=5:rc-lookahead=120:lookahead-slices=1:no-sao=1:psy-rd=2.1" -c:a copy -c:s copy
