x265 encode for HW player

Hello.

I'm used to x264, but i'm an absolute noob with x265.

One of my favorite old movie is out in new BD-UHD 4k HRD, so i've bought it, i'll rip it, denoise, and want to re-encode.
I've read a lot of things about how to retrieve DoVi and HDR10+ meta-data, so i think i'll be able to manage this part.

I'm used to do that with simple BD : rip the BD, denoise, re-encode and make my own Blu-Ray, or sometime just an mkv.
In the last case, i'm not using strict Blu-Ray compliant parameters, but close enough to stay HW player compliant :
Level 4.1, vbv-maxrate=40000 and vbv-bufsize=30000.
If you use average bitrate=20000 it will provide an average quality encode, not too far from BD quality, but higher than usual 8000 to 12000 re-encode.

I want to do the same thing for the BD-UHD, but i have no idea, first, what vbv-maxrate/vbv-bufsize are BD-UHD compliant, and the level.
My pure guess is to use BDx2 =>
vbv-maxrate=80000
vbv-bufsize=60000
bitrate=40000
level....????
Hoping that will provide HW player (like Zappiti Neo) compliant stream.
But are they ?

So, i gladly take any information about these parameters.

Yeah that is gonna be safe. The video of UHD-BDs is generally 50 Mbit/s, so by putting it to 40 with some overshooting margin you're gonna be safe.
If you want to play extremely safe, remember keyint = framerate and to disable opengop.


I don't generally make UHD-BD, but when I had to encode stuff for distribution and mux it in .ts which had to play on consumer hardware in BT2020 HLG 25p, I did this:

pause
and it played everywhere, including on UHD-BD players.

Sure enough, it's not the best quality, but still it played fine.
I think your settings are gonna be fine, though.

UHD-Bluray is using main10 level 5.1 high tier, which has a max bitrate of 160Mbps (so that would be maxrate and bufsize at 160000 to be vbv compliant), however the uhd-bluray-spec states a maximum bitrate of 100Mbps for the video stream and there are then a maximum rate for the total ts stream that depends on the disc used but usually its 109Mbps. Keep in mind that the rates for these physical disc formats are set by the limit of the slow read speed of the optical discs, the video decoder can most likely handles the maximum rate that the standard specifies for that level.

I would set --level-idc 51 (this ensures that you wont break level compliance in regards to ref-frames etc, setting this is the key thing to ensure playback compatibility) & --vbv-maxrate 98000 --vbv-bufsize 98000 if you wanna keep it in line with uhd-bluray. From what i've seen uhd-blurays bitrate usually averages around 40-60Mbps (it can differ quite a bit depending on running length and disc used), but i would highly recommend using crf instead of fixed avg bitrate for the re-encode.

Thanks for the answers.

I've made some search and thought that x265 accept now directly avs without needing pipe ffmpeg stuff (which wasn't the case in the begining), am i wrong ?
Don't realy want to be strictly UHD compliant, just HW. When i'm doing mkv just HW play compliant, not targeting BD, i don't restrict keyframe to 1s and i keep open gop.
But the thanks, the command lines will help me, as i intend to do multipass encode, not 1 pass crf.

But i'll made some testing during this week end.

Reading this, i thought that x265 has native avs input support, as there is some tests labeled "AVS only using Crop via DIRECT INPUT"/"AVS_nopipe".

Am i mistaking ?

@jpsdr,
I could well be wrong but,
I think that avs input may need to be "enabled" during compile of x265,
I think I remember that everything is enabled in Lord Mulder's Simple x264 Launcher [includes x265],
I stole the x265 [8 and 10/12/ bit] encoders from simple launcher and am using with MeGUI x64.

Simple x264/x265 Launcher v3.01 (2020-12-08) :- https://forum.doom9.org/showthread.p...+x264+launcher

EDIT: OOps,
Looks like I'm wrong about that, [guess I got mixed up with the version of ffmpeg I'm using]
Code:
C:\Users\steve>x265 --fullhelp

                                 If given, x265's Dolby Vision metadata parser will fill the RPU field of input pictures with the metadata read from the file. Default NULL(disabled).
   --nalu-file <filename>        Text file containing SEI messages in the following format : <POC><space><PREFIX><space><NAL UNIT TYPE>/<SEI TYPE><space><SEI Payload>
Dont seem to be any mention of AVS, and MEGUI looks like it pipes via ffmpeg.

Just in case anybody else stumbles across jprsd request for Avs input compatible x265 executable,

Barough posted this in another thread,

Everything is going great.

I have a good x265 version i can directly provide my avs file.

I've first made a quick encode with ultrafast preset on the first 2000 frames of the movie, inserting the rpu DolbyVision i've extracted from it. It works !!! My player and my TV identify properly the final MKV as DolbyVision. At least, i have the "DolbyVision" message displayed.

For 4k video the denoising speed is 1.8fps, so i should have the result file tomorrow evening. But it's the first time i'm working with 4k movie for denoising, and when proper remaster is done, because of 4k, denoising... Well, technicaly it's "removing grain", produce better result for heavy grain (at least it is for this case).

I've tested the setting i can put to encode, placebo and veryslow gave me 0.1fps, it's a little slow...
Slower gave me 0.4fps, which is... acceptable. So, as i'm doing multipass encode, i should have my movie encoded for the end of the week.

I don't think i'll do this often, only for movies :
- I REALY REALY like.
- There is a 4k proper good remaster done.
Because... Almost a week for a movie... Realy motivated !

When i'm doing this for simple FHD Blu-Ray, it's a lot faster !!!

What's the advantage for you over just extracting the HEVC bitstream as is without reencoding?

Yeah, a UHD Blu-ray is 4x the pixels and 1.25x the bit depth. All things being equal, you'd expect it to be 5x slower with the same codec. And x265 is a lot slower than x264 for equivalent profiles. Of course, you can run x265 in a faster preset if you don't care about file size too much.

Ah, so it's more than you're reprocessing for stylistic reasons, and then reencoding that output? Makes sense.

The most complete interface to x265 AFAIK is StaxRip.

It has some steep learning curve, not because it's difficult, but as it wants to decide lot of things on its side, so you have to find and disable,

Anyway, the x265 panel is really complete: you can find ANY parameter.

Once you have found the "perfect" settings, just copy the switches you need most and go by CLI, if you prefer.

WHY ????? Why there is only 129744 encoded frames when the number of frames on the file is properly detected at 129984 ?
The 3 log files have the same issue !

Is it because of --frame-dup, and is mkvtoolnix in that case unable to mux properly the result file ? Because i have audio/video totaly (few seconds) out of sync. Also, the first few seconds of the video is a total black (which can create a lot of frame dup in the begining).

a. I think the numbers are 'okay' since the dup frames do probably not count into the encoded frames.
b. I can reproduce this behaviour, but it's either a bug in x265 or it's not only mkvtoolnix. Same thing happens when MP4Box or ffmpeg are used for muxing. (tested with a clip which starts with a few seconds of black and one can clearly see the audio beeing async)
-> I would be interested in this too. (for anyone wanting to test this: --frame-dub requires hdr signaling and vbv, otherwise it gets disabled)

Why do i have the FLAW for --hdr10-opt when there is --video-signal-type-preset BT2100_PQ_YCC which set everything as --hdr10-opt is expecting ???

Is it possible that an option adding some kind of timing information is missing to be used with --frame-dup for mkvtoolnix being able to properly mux the stream ?

Isnt x265 duplicating pictures by means of the picture timing SEIs ? Then its normal that it drops pictures. The muxer has to evaluate the SEIs though. The SEIs should present when --hrd is specified.

It's x265 or bugland ????? I mean, since the time !
I've replaced --video-signal-type-preset BT2100_PQ_YCC by --colorprim bt2020 --transfer smpte2084 --colormatrix bt2020nc --range limited --chromaloc 2 which is supposed to be exactly the same according the doc, but it seems not, because --hdr10-opt is not complaining anymore.

10 days wasted... i'm a little not happy...

If you look here:

https://bitbucket.org/multicoreware/...cpp#lines-4368

In line 4368 it checks for the HDR10 opt parameters and below that in line 4383 it applies the preset.

Maybe test with a 30 seconds or 1 minute sample before encoding the whole movie again ?

I have been thinking about that frame dup thing and I dont know, Player support, with Dolby Vision, its kinda a stretch. I would just drop it. Duped frames are really tiny when encoded anyway so it does not matter in the end.
