Remove information Matrix coefficients : BT.709 - murriato - 08.03.2024

Hello Mr. Selur, good afternoon, first of all, I would like to apologize because I am from Spain, I do not speak English, I am translating the text with Google.
I have a template to make 1080p x265 encodes and for now everything is perfect but for a few days I have been getting information in the media info that I do not understand and I don't know why I am getting it.

Language : Spanish
Default : Yes
Forced : Yes
colour_range_Original : Limited
Color primaries : BT.2020
Transfer characteristics : PQ
Matrix coefficients : BT.709
matrix_coefficients_Original : BT.2020 non-constant
Mastering display color primaries : BT.2020
Mastering display luminance : min: 0.0050 cd/m2, max: 1000 cd/m2

I wanted to ask you how I can remove that information from the encode?

In all the previous encodes I did not get Matrix coefficients: BT.709

Madia info source:

ThanksPlease,

Matrix coefficients                      : BT.709

matrix_coefficients_Original             : BT.2020 non-constant

Indicates that the video stream is tagged as 'BT.2020 non-constant' but the container is tagged as 'BT.709'.
Looking at the Encoding call:

ffmpeg_32 -y -loglevel fatal -noautorotate -nostdin -threads 8 -i "C:\Users\cebol\Desktop\ENCODES\HYBRID\encodingTempSynthSkript_2024-03-08@15_32_12_8510_0.avs" -an -sn -color_primaries bt2020 -color_trc smpte2084 -colorspace bt709 -color_range tv -pix_fmt yuv420p10le -strict -1 -vsync 0 -f yuv4mpegpipe - |  x265 --input - --fps 24000/1001 --output-depth 10 --y4m --profile main10 --level-idc 5.1 --qg-size 16 --tu-intra-depth 4 --tu-inter-depth 4 --limit-tu 4 --me star --subme 7 --limit-modes --max-merge 4 --no-early-skip --rskip 0 --no-open-gop --opt-ref-list-length-pps --min-keyint 23 --bframes 16 --weightb --ref 5 --rc-lookahead 60 --lookahead-slices 0 --crf 15.00 --opt-qp-pps --cbqpoffs -2 --crqpoffs -2 --ipratio 1.30 --pbratio 1.20 --rd 4 --psy-rd 2.01 --rdoq-level 2 --psy-rdoq 2.01 --aq-mode 3 --no-cutree --vbv-maxrate 160000 --vbv-bufsize 160000 --hrd --vui-hrd-info --deblock=-3:-3 --no-sao --selective-sao 0 --range limited --colorprim bt2020 --transfer smpte2084 --colormatrix bt2020nc --chromaloc 2 --master-display "G(8500,39850)B(6550,2300)R(35400,14600)WP(15635,16450)L(10000000,50)" --hdr10 --hdr10-opt --sar 1:1 --output "C:\Users\cebol\Desktop\ENCODES\HYBRID\2024-03-08@15_32_12_8510_02.265"

'--colormatrix bt2020nc' is correctly used, which is why the video stream is correctly lagged.

Looking at the muxing call:

"C:\Program Files\Hybrid\64bit\mkvmerge.exe" --ui-language en -o "C:\Users\cebol\Desktop\ENCODES\HYBRID\2024-03-08@15_32_12_8510__04.mkv" --global-tags "C:\Users\cebol\Desktop\ENCODES\HYBRID\mkvtags_2024-03-08@15_32_12_8510__04.xml" -d 0 --default-track 0:yes --colour-matrix-coefficients 0:1 --colour-range 0:-1 --colour-transfer-characteristics 0:2 --colour-primaries 0:2 --language 0:es --default-duration "0:24000/1001fps" --aspect-ratio-factor 0:1/1 --no-chapters --compression -1:none --forced-track 0:yes --field-order 0:0 --no-audio --no-subtitles "C:\Users\cebol\Desktop\ENCODES\HYBRID\2024-03-08@15_32_12_8510_02.265" --track-order 0:1

'--colour-matrix-coefficients 0:1' is used instead of "--colour-matrix-coefficients 0:10".

I tried reproducing the problem, and the only way I can reproduce this is to enabled "Config->MKV tagging->VUI->Matroska advanced video signaling" and overwrite the VUI flags for the container settings.

So my guess is that you enabled "Config->MKV tagging->VUI->Matroska advanced video signaling" and overwrote the matrix there.
If that is not the case, please write a step-by-step guide what you are doing, so that I can reproduce the problem.

Thank you very much, Mr. Selur, the problem has been solved with the instructions you told me.
"Config->MKV tagging->VUI->Matroska advanced video signaling" and overwrite the VUI flags for the container settings.

Happy that solved it for you.
