Yep, found that, too
Actually a lot of parameters can just be copied ... like colormatrix, master-display and so on, even the audio...

Doesn't that make your job a lot easier?

Yes, for NVEncC -- but I'll also have to make it work for X265 encoding. That means I'll probably have to create a JSON file from the extracted HEVC file, so it can be referenced from the command line -- which will add about 6-10 minutes to each job.

As for the other settings that can be copied... they are readily available in a BD structure and BD-RB already has the code to extract it and use it. My attention-to-detail tendencies also make me want to have control over things like that rather than "trust" other software.

Just a note on that. In my testing, I'm finding (as you might expect) that X265 is significantly more efficient than the NVIDIA hardware encoder. For example, if you encode some sources with a CQM of 25 using the hardware encoder you will get a file that is twice as large as one created by X265 with a CRF of 25. Of course you also have to factor in that the hardware encode is about 20-40x faster...

Would you say that the quality (in terms of metrics or by visual comparison) is about the same for the CQM=25 (HW, h.265) and and CRF=25 (SW, x265) encodes?

I'm not sure. I don't like doing subjective comparisons, so I'll have to use AVISYNTH and do some SSIM testing.

More on the "--multipass" thing: It turns out that setting --vbrhq mode automatically sets the encoder to do 2 pass-full. So I'm not sure that there is actually any additional capability associated with that parameter other than it may provide a bit of granularity (with the ability to set 2pass-quarter).

well yess compressing around 80 gig to 25 will have its tradeoff in quality, i think for h264 max quality, is like x264 medium not sure with 265

hmm i wonder if the AMD Ryzen Threadripper 3970X Processor (32 Core / 64 Threads , 128 MB Cache, 4.5 GHz Boost) would bring x265 times down ? its only 1.8k for the chip :P

The discussion of quality settings makes me smile. My first BD backup/conversion, in Oct 2008 before BD-RB was born iirc, was Live Free or Die Hard which as you all know is action-packed. Yet when compressed to less than 4GB DVD-size it looked flippin' awesome the couple times I played it. I will have to break it out sometime and see how it holds-up 12 years later!

Test Release of BD-RB -- with NVENC support

I've created a test release (v0.61.06) of BD Rebuilder for anyone who would like to experiment and report any issues they see with the new support for NVIDIA/NVENC support.

Please note that in order to use the new capability you must run BD-RB on a system that has an NVIDIA card installed that supports NVENC. You can find out more about which cards can be used at this link. BD-RB does a check when you attempt to select the NVENC encoder (under the SETTINGS menu).

There were a considerable number of changes to this release, so this version should be considered "for testing purposes only", so I'm not updating the first post of this thread -- please try it and let me know your experiences and report any bugs you find.

BD-RB v0.61.06

Thanks.

Can I just say, I hate Norton... gives issues on the NVEncC.exe included with BD-RB (says RISK:WS.Reputation.1). didn't have issues with one I downloaded separately.

(had to restore and exclude this)

First encode looks pretty awesome, but I wanted to compare more closely, so I tried AviSynth interleave (first time for me) on the m2ts files

Immediately I noticed random artifacts on the reencoded file.

Code:
a=DirectShowSource("U:\FullDisc\OLYMPUS_HAS_FALLEN\BDMV\STREAM\00021.m2ts").Subtitle("O", align=2, size=30, text_color=$ffffff)
b=DirectShowSource("U:\BD-Output\OLYMPUS_HAS_FALLEN\BDMV\STREAM\00021.m2ts").Subtitle("NV", align=2, size=30, text_color=$ffffff)
return interleave(a, b)
Playing the resulting file alone is without artifacts...
Any Hints from the AviSynth pro's?

Original M2TS on disc 59.4 GB, resulting file from BD-RB is 27.6GB, so a nice reduction in size.

Playback on my 1080p monitor looked good. Will check on my 4K TV as soon as I get a chance to step away from my desk.

I also just started a Full Backup to BD-25.. Will post results in a little bit.


NOTE: my graphics card is an EVGA GTX 1660ti XC Ultra Gaming 06G-P4-1267-KR (full PC spec's HERE )

b=DirectShowSource("U:\BD-Output\OLYMPUS_HAS_FALLEN\BDMV\STREAM\00021.m2ts").Subtitle("NV", align=2, size=30, text_color=$ffffff)
return interleave(a, b)
Playing the resulting file alone is without artifacts...
Any Hints from the AviSynth pro's?
Don't use DirectShowSource. Make .dgi index files of the 2 files (original and encoded) instead.

.dgi sounds like DGDecNV ... Oh well, seems I have to invest that money ..

Not that it matters, it's just a question.

HEVC is for UHD-BD only ... wouldn't be compliant with (Full-HD) BD
I think BD-RB has always been like that (also with x264/x265) to be compliant with disc standards.

Seems to work for Alternate Encoding though

It follows the same rules as X265/X264. The only way to force a 1920x1080 source to HEVC would be with ALTERNATE output.

I am working on that ability -- to create a 1080p HEVC (UHD format) disc -- but I disabled that code for this release because I haven't tested it very well.

The UHD standard also allows 1080p using HEVC. So that part should be available soon. See the table below from the Part 3 Whitepaper.

But, just as an aside... I have tried other formats (720p and 480p) using HEVC and UHD (V3) disc output and they also play on my Sony player -- so I might put a hidden option that allows HEVC there as well. It would be a great non-standard-but-working capability for creating series discs, since HEVC looks a lot better at lower bitrates. I'm usually hesitant to step out of the standard -- but I'd bet that most UHD players will accept it since the format/type tables have settings for it.

Can you implement that as Alternate Output setting for HEVC with AC3, too?
Would be a nice addition, because my SamsungTV can't play DTS and some older SmartTV models had trouble playing AAC ...

AC3 just plays everywhere

You can easily create a preset that uses AC3 by editing the ALTERNATE.TXT file in the Misc folder. The comment area at the beginning of the file explains the settings. Here's an example you could try:

[00041]
caption=MKV Container, HEVC, NO_RESIZE, Auto-AC3
vEncoder=1
vBitrate=1500
vKeyint=Auto
aBitrate=*
aType=0
vFormat=7
cType=1

I used [00041] because the default ALTERNATE.TXT file has 40 entries in it. Just adjust if yours has more or fewer. You could also replace one of the existing presets if you'd like that better.

Honestly I thought I'd put one in there. I'm surprised that I didn't.

Wow, I've never noticed that file ...

If you'd like to experiment with the capability to output 1080p to disc using HEVC into a UHD format, try adding:

UHD_V3_MODE=1

...to your INI file. I haven't tested it much, but I'm pretty sure it would only work in movie-only mode right now. Don't forget to reset it to 0 after playing with it -- as it will try to make normal BD backups into UHD format.

[Edit] Nope... sorry. I just ran a test on a 1080p source and, while it played, BD-RB failed to add the "--repeat-headers" parameter in the encode and FF/REW/CHAP isn't working (for 1080p output). I fixed it for the next release.
