how to use ffmpeg to encode to mp4-avc-HDR-4k

hydra3333 · 10th February 2018, 05:45

OK, call me stupid.

Googled for a couple of hours, found a plethora of semi-conflicting information, and am still not much clearer on what ffmpeg commandline switches to use to convert (re-encode) a 4K HDR webm video, eg vp9.2, (and other similar samples in various formats from across the web) into

an mp4 container as avc/HDR/4k, presmably profile high10 level 5.1
an mkv container as avc/HDR/4k, presmably profile high10 level 5.1

an mp4 container as hevc/HDR/4k
an mkv container as hevc/HDR/4k
equivalent in quality to the avc

I'd prefer to use ffmpeg rather than x264 and x265 if possible.

Any example commandlines and/or link(s) would be very greatly appreciated.

So far I've seem something like this

Code:

ffmpeg_10bit.exe -i <infile.i420.bt2020nc.yuv420p10le.webm> -input-depth 10 -c:a libopus -c:v libx265 -tag:v hvc1 -crf 15 -pix_fmt yuv420p10le -x265-params "colorprim=bt2020:transfer=smpte2084:colormatrix=bt2020nc" -f mp4 -y "outfile.mp4"

and this which I'm fairly sure isn't right

Code:

ffmpeg.exe -i <infile.i420.bt2020nc.yuv420p10le.webm> --input-depth 10 -c:a libopus -c:v libx264 --preset slow -crf 15 -no-open-gop -profile high10 -level:v 5.1 -level-idc 5.1 -pix_fmt yuv420p10le -colorprim bt2020 -colormatrix bt2020nc -transfer smpte-st-2084 -x264opts "" -movflags faststart  -f mp4 -y "output.mp4"

at least for x265 you will have to add master-display and max-cll to the command line as parameters
"colorprim=bt2020:transfer=smpte2084:colormatrix=bt2020nc:master-display=G(13250,34500)B(7500,3000)R(34000,16000)WP(15635,16450)L(10000000,10)"
and may be ':max-cll=0,0'
don't think there is an option in ffmpeg to passthrough these settings to libx265

sneaker_ger · 10th February 2018, 12:04

And don't simply copy them from Selur's example. You have to read them from the source. Try MediaInfo to show the values. If that doesn't work try mkvinfo for VP9/WebM, a stream analyzer like ffprobe or Zond for HEVC.

You may need to calculate the values. They are set (stored) differently than they appear in MediaInfo:

HDR in H.264, albeit possible, is uncommon. I would not use it for lack of compatibility. I think x264 does not even implement the mastering display colour volume SEI yet. (You can flag the mkv container, though.)

hydra3333 · 11th February 2018, 02:46

OK, thank you for the information !

I'd mistakenly thought h.264 10bit HDR was now "a thing", so I will avoid that and stick with h.265 HDR.

As you both suggest, I'll start looking into the meanings of master-display and colorprim and max-cll and read these docs

http://x265.readthedocs.io/en/defaul...master-display
https://matroska.org/technical/specs/index.html#Colour

and at the info produced by MediaInfo, mkvinfo and ffprobe.

Thank you, now I have a useful place to start, a lot better than aimless wandering

hydra3333 · 11th February 2018, 10:44

OK, ffprobe seems to show the most info.
From the ffprobe output below, these seem to be the most relevant items which can be "extracted" from an ffprobe output.
Although, I'm not sure where the 2 values for "max-cll=0,0" come from.

Further advice welcomed.

Code:

pix_fmt=yuv420p10le
color_range=tv
color_space=bt2020nc
color_transfer=smpte2084 (does this need to be transformed into "smpte-st-2084" ?)
color_primaries=bt2020
red_x=34000/50000  (discard eveything on and after the "/")
red_y=16000/50000  (discard eveything on and after the "/")
green_x=13248/50000 (discard eveything on and after the "/")
green_y=34500/50000 (discard eveything on and after the "/")
blue_x=7500/50000 (discard eveything on and after the "/")
blue_y=3000/50000 (discard eveything on and after the "/")
white_point_x=15634/50000 (discard eveything on and after the "/")
white_point_y=16450/50000 (discard eveything on and after the "/")
min_luminance=50/10000 (discard eveything on and after the "/")
max_luminance=10000000/10000 (discard eveything on and after the "/")

And then maybe plugged into ffmpeg's x265 "-x265-params" like this (not yet attempted)?

Code:

ffmpeg.exe 
-input-depth 10 
-pix_fmt %pix_fmt% 
-i "G:\HDTV\0nvencc\vp9_2_HDR10_UHD_4K_Demo.webm"
-i input.vp9.2.webm -an 
-c:v libx265 -preset slow -crf 15 
-x265-params "colorprim=%color_primaries%
:transfer=%color_transfer%
:colormatrix=%color_space%
:master-display=G(%green_x%,%green_y%)B(%blue_x%,%blue_y%)R(%red_x%,%red_y%)WP(%white_point_x%,%white_point_y%)L(%max_luminance%,%min_luminance%)
:max-cll=0,0:hdr" 
-profile:v main10 -level:v 5.1 
-crf 18
-output-depth=10 
-movflags faststart
-f mp4 -y output.mp4

Here's the ffprobe output to see if someone can point out where the "max-cll=0,0" values come from.

Code:

"C:\SOFTWARE\ffmpeg\0-homebuilt-x64\ffprobe.exe" -prefix -unit -pretty -show_streams -i "G:\HDTV\0nvencc\vp9_2_HDR10_UHD_4K_Demo.webm"

edit: also wondering if the profile level needs to be 5.2 given it's 4k 60fps main10 HDR, athough it looks as if 5.1 would suffice ?

Not each source has max-cll value flags set, your source probably hasn't.

In case it's present MediaInfo reports them as:

Code:

Maximum Content Light Level              : 1000 cd/m2
Maximum Frame-Average Light Level        : 400 cd/m2

not sure whether ffprobe reports these at all,...

sneaker_ger · 11th February 2018, 12:58

For me it's reported directly below the other values.

Thank you. ffprobe was from a build from git as of last night

mediainfo is the latest 17.12 and doesn't show it.
re-trying ffproble from latest git ...

edit: no, not shown anywhere

it must be this.

I wonder what would happen if I added ":max-cll=0,0"

sneaker_ger · 11th February 2018, 13:40

Then maybe the SEI simply isn't there as Selur suspected. Try different sample.

Selur · 11th February 2018, 13:52

@sneaker_get: You are right, one has to use '-show_entries side_data' wo see the max_content/average info.

it seems not to be there no matter what I try...

Selur · 11th February 2018, 14:40

I would probably stick with the default x265 uses (max-cll “1000,400”) or simply not set the value.

Code:

--hdr can be used to ensure that max-cll and max-fall values are always signaled (even if 0,0).

OK, now worth a try I guess.

PS appreciate the links.

Well, so much for that. ffprobe on the resulting mp4 said

Code:

pix_fmt=yuv420p10le
level=150
color_range=tv
color_space=unknown
color_transfer=unknown
color_primaries=unknown
chroma_location=unspecified

whilst the original .webm said

Code:

pix_fmt=yuv420p10le
level=-99
color_range=tv
color_space=bt2020nc
color_transfer=smpte2084
color_primaries=bt2020

I guess I'll need to look at the ffmpeg commandline to see what options go with codec libx265

sneaker_ger · 13th February 2018, 18:07

Also with
-x265-params "colorprim=9:transfer=16:colormatrix=9" (etc.)
?

Thank you. I got a tad "brute forcey" with it and this seemed to work, transferring the input file (eg vp9.2) 4k/HDR 10-bit colour characteristics over to the output file when transcoding into h.265 ...

Please read the log next time.

you have --max-cll="4000,300"

shouldn't it be --max-cll "4000,300" ? without the equal sign?

Yes. Thank you both. Serves me right for tinkering with 2 different tools at the same time with different commandlines

hydra3333 Registered User Join Date: Oct 2009 Location: crow-land Posts: 540	how to use ffmpeg to encode to mp4-avc-HDR-4k OK, call me stupid. Googled for a couple of hours, found a plethora of semi-conflicting information, and am still not much clearer on what ffmpeg commandline switches to use to convert (re-encode) a 4K HDR webm video, eg vp9.2, (and other similar samples in various formats from across the web) into an mp4 container as avc/HDR/4k, presmably profile high10 level 5.1 an mkv container as avc/HDR/4k, presmably profile high10 level 5.1 an mp4 container as hevc/HDR/4k an mkv container as hevc/HDR/4k equivalent in quality to the avc I'd prefer to use ffmpeg rather than x264 and x265 if possible. Any example commandlines and/or link(s) would be very greatly appreciated. So far I've seem something like this Code: ffmpeg_10bit.exe -i <infile.i420.bt2020nc.yuv420p10le.webm> -input-depth 10 -c:a libopus -c:v libx265 -tag:v hvc1 -crf 15 -pix_fmt yuv420p10le -x265-params "colorprim=bt2020:transfer=smpte2084:colormatrix=bt2020nc" -f mp4 -y "outfile.mp4" and this which I'm fairly sure isn't right Code: ffmpeg.exe -i <infile.i420.bt2020nc.yuv420p10le.webm> --input-depth 10 -c:a libopus -c:v libx264 --preset slow -crf 15 -no-open-gop -profile high10 -level:v 5.1 -level-idc 5.1 -pix_fmt yuv420p10le -colorprim bt2020 -colormatrix bt2020nc -transfer smpte-st-2084 -x264opts "" -movflags faststart -f mp4 -y "output.mp4" Last edited by hydra3333; 10th February 2018 at 05:48.

Selur Registered User Join Date: Oct 2001 Location: Germany Posts: 7,034	at least for x265 you will have to add master-display and max-cll to the command line as parameters "colorprim=bt2020:transfer=smpte2084:colormatrix=bt2020nc:master-display=G(13250,34500)B(7500,3000)R(34000,16000)WP(15635,16450)L(10000000,10)" and may be ':max-cll=0,0' don't think there is an option in ffmpeg to passthrough these settings to libx265 __________________ Hybrid here in the forum, homepage

Selur Registered User Join Date: Oct 2001 Location: Germany Posts: 7,034	Not each source has max-cll value flags set, your source probably hasn't. In case it's present MediaInfo reports them as: Code: Maximum Content Light Level : 1000 cd/m2 Maximum Frame-Average Light Level : 400 cd/m2 not sure whether ffprobe reports these at all,... __________________ Hybrid here in the forum, homepage

Selur Registered User Join Date: Oct 2001 Location: Germany Posts: 7,034	I would probably stick with the default x265 uses (max-cll “1000,400”) or simply not set the value. Code: --hdr can be used to ensure that max-cll and max-fall values are always signaled (even if 0,0). source: http://x265.readthedocs.io/en/defaul...notes.html#id8 __________________ Hybrid here in the forum, homepage Last edited by Selur; 11th February 2018 at 14:43.

hydra3333 Registered User Join Date: Oct 2009 Location: crow-land Posts: 540	OK, thank you for the information ! I'd mistakenly thought h.264 10bit HDR was now "a thing", so I will avoid that and stick with h.265 HDR. As you both suggest, I'll start looking into the meanings of master-display and colorprim and max-cll and read these docs http://x265.readthedocs.io/en/defaul...master-display https://matroska.org/technical/specs/index.html#Colour and at the info produced by MediaInfo, mkvinfo and ffprobe. Thank you, now I have a useful place to start, a lot better than aimless wandering

hydra3333 Registered User Join Date: Oct 2009 Location: crow-land Posts: 540	Well, so much for that. ffprobe on the resulting mp4 said Code: pix_fmt=yuv420p10le level=150 color_range=tv color_space=unknown color_transfer=unknown color_primaries=unknown chroma_location=unspecified whilst the original .webm said Code: pix_fmt=yuv420p10le level=-99 color_range=tv color_space=bt2020nc color_transfer=smpte2084 color_primaries=bt2020 I guess I'll need to look at the ffmpeg commandline to see what options go with codec libx265
