Help me for HDR10 4K encoding

[doostanehsoft]

Hi guys.
I've trying to encode HDR 4k, But it dosnt being like source movie.
my output movie is too shining, but source file is really darkest:

my release:
[Attachment 69620 - Click to enlarge]
source release:
[Attachment 69621 - Click to enlarge]

and this is my preset:

--deblock -3:-3:-3 --output-depth 10 --frame-threads 12 --rc-lookahead 60 --subme 4 --colorprim bt2020 --transfer smpte2084 --colormatrix bt2020nc --master-display G(8500,39850)B(6550,2300)R(35400,14600)WP(15635,16450)L(10000000,0) --max-cll 711,617

Are you trying to maintain the HDR or strip it?

I wanna maintain it. I trying to encode a real HDR10.

Just a simple command line like this copies over all the HDR attributes from the source; I tested it on my TV and it works properly
ffmpeg.exe -i "source_HDR.mp4" -c:v libx265 -c:a copy new_HDR.mp4

SO not sure why yours is not working Your bottom image does not look like HDR should look; either encoded wrong
or media player is not playing properly
the top one does look very bright, this is often how HDR looks

i dont want make a copy of source! i want to rip and compress it.

I need a hdr preset that keep hdr colors and its dark effects.

The simple command line I gave does re-encode the video - it just copies the attributes, such as the existing colorspace . You can add/modify to it to your liking.
Or just try it as is first and see what else it needs

Or just encode it in Handfbrake or Vidcoder instead of FFmpeg

its working tnx, but my new release presets is too simillar the previous release. its too bright.
Really i encoded through avisynth, from premiere.

For any further analysis provide a short clip of your source showing the problem

Yes I see the problem; it's possible you have to add something else to FFmpeg to fix this, but it's beyond my experience.
Tried the encode in Vidcoder, seems good

i've tested it without avisynth and premiere and the problem was fixed.
i have to do some edit on movie first (with Premiere), and then encode it with the help of frameserver (on Premiere) and avisynth (on ffmpeg).
i guess the problem is related to the avisynth script or frameserver plugin of preimere.
in your opinion, could it related to the avisynth script, like YV12 code or etc?
ConvertBits(8)
ConvertToYV12()

Yes it could be. why do you need either of these?

my 2cents:
Assuming you are encoding to HDR10 as output and not to SDR.
My guess is what happens:
When Premiere opens the source file directly, it sees that the content is HDR10 and copied the hdr metadata from the input to the output. (or configured the Premiere project accordingly)
When Premiere opens the source through AviSynth, that metadata is missing, thus Premiere handles the content as SDR.
So to let Premiere know that the content is HDR you need to add the metadata manually. Since I never used Premiere, I have no clue how to set color matrix, min/max light level, master display info and luma range, but from what I read this seems to be the issue to me.

so as you said, the outputs from premiere, all are SDRs and its useless for me that i use HDR presets for this project, is this right?
