I know it will happen somewhat just by compressing but for my test title going from the source 54gb to 43gb the peak bitrate might still be too high for BD-50 media.
Ok, I think I answered somewhat my own question here but just for clarification;

I found this setting in the 'HiddenOpts' files: "UHD_MAXRATE=n n = Maximum bitrate, Sets X265 maximum bitrate parameter (min 15000, max 60000, default 45000)"

So if I add to the BDrebuilder.Ini file "UHD_MAXRATE=40000" it should limit the maximum bitrate to 40Mbps of just the video track? The default of 45000 seemed too high for my player at one spot as it stuttered and froze a bit.

And if that is true does BDRebuilder then take that into consideration when compressing the original? So will it be;

Original size 54gb and max bitrate of 60Mbps
BDRebuilder size 47gb and max bitrate of 40Mbps

Or will it ensure the bitrate comes before the size, so you may end up with a much smaller output;

Original size 54gb and max bitrate of 60Mbps
BDRebuilder size of 41gb and max bitrate of 40Mbps

I know there are other variables to the sizing but I mean in general will it still try to reach that 47gb size?

The maximum bitrate applies to only the video track. You'd have to account for all audio tracks as well.

Hello. Can you recommended a capable stand alone player for 25GB Discs 4K?

In case it's of any relevance after reverting the NVENC update proposed by cartman0208 and any .ini changes (so it's back to as you supply it all) I attempted another similar project but this time, the content is all PAL telecined - so no pulldown. And that has encoded fine, and quickly.

As an aside and to recap - I also found that with my earlier NTSC content, using tsMuXeR to remove pulldown on the source (so, 24p SD content) that also worked. So I'm beginning to suspect handling of pulldown may be what's triggering this.

That will only work if the 480i video (no such thing as NTSC digital video, as it is an analog format) is 23.976 video containing pulldown flags so that it plays back at 29.97. If it is true 29.97 interlaced video, then the video must be re-encoded using programs like AVISynth to do the IVTC, which is then passed to an x264, or x265, encoder. So, don't count on tsmuxer to always be able to do the job.

@MrVideo Yes, the project I initially failed on consisted of NTSC SD film based content, so it did have pulldown flags which I did not originally attempt to remove - so it tried and failed to encode at 29.97, as I have done previously successfully using the CPU X264 encoder. I do acknowledge that true video NTSC content will differ; I haven't yet attempted any of that using NVENC. I also acknowledge what you say about NTSC representing (properly) a broadcast system for analog - but it is used in common parlance - both on DVD artwork and in certain editing apps (eg Premiere Elements) to represent pretty much anything that isn't 25 or 50hz (= PAL).

Keep in mind that hard telecined 480i29.97 video is filmed based. BDRB has all of the tools necessary to IVTC any form of telecined video, i.e., with or without pulldown flags. So, I'm not sure why you would be having issues with it.

In my case, I have a system set up to do re-encoding of video, including files from DVDs, that are telecined in order to return them to 23.976fps.

DVDs have a long history in that the output was strictly analog, hence the use of NTSC, or PAL. Playing DVDs, or Blu-rays, are done on equipment that only outputs a digital signal, so analog terms no longer fit. To properly describe a video these days is the use the resolution and frame rate, i.e., 480i29.97 or 576i25. Also, once you IVTC 29.97 back to the original 23.976, it can no longer be described as NTSC under any circumstances, since that frame rate does not exist in the NTSC analog world.

Shame on Adobe for using the NTSC/PAL terms when working with digital video, since it is only digital video that it works with.

Me neither

BD Rebuilder v0.61.22

I've updated the first post of this thread with a link to the latest version (v0.61.22) of BD-RB. Changes for this release:
Code:
- Fixed an error in which 1080p HEVC sources
  on UHD discs could create an error when
  attempting to rebuild.
- Corrected a syntax error in the way BD-RB
  checks for H.265 capability in video card.
- Added support for import of AV files that
  have OPUS format audio.  LAVFilters must
  be version 0.68 or above.
- Fixed an error that could cause BD-RB to
  fail with err "ReencodeAudio() 00009  1801"
- Enabled the use of NVENCC for converting 
  non-compliant sources during import.  It 
  is also used to convert VFR sources to 
  CFR.  If issues are encountered it can be
  disabled by adding NVENC_CONVERT=0 to the
  BDREBUILDER.INI file.  Please report any
  issues found in the BD Rebuilder bug thread
  on Doom9.org. 
- Improved the method used in output file
  naming when importing/reencoding a single
  file to ALTERNATE format.
- Added code to adjust for leading clips in
  a multipart source that do not contain
  audio.
- Updated NVENCC.EXE to newer version 5.20.
- Updated TSMUXER4K.exe to the 4/30 release.
- Other minor corrections and cosmetic fixes.

So, its not imperative to use LAVFilters version 0.65 anymore? How about the out-of-sync audio?

I haven't changed the recommended version. But v0.65 doesn't work with OPUS audio. Then again, it isn't very common. But I've been testing v0.68.1 and haven't run into any problems. I can't remember... what version was it that had the out-of-sync issue?

AV1 Enoder

Is there any possibility of including an AV1 encoder for Movie Only encodes?

V0.61.22

Does BDRB not like an HEVC video file with two video streams?
Code:
 - [23:56:22] Processing: VID_00500 (3 of 12)
 - [23:56:22] Extracting A/V streams [VID_00500]
EXIT CODE: -2
   - Extracting video streams [VID_00500]
   - Extracting secondary video [VID_00500]
   - Extracting audio/subtitle streams [VID_00500]
 - [23:58:54] Reencoding video [VID_00500]
   - Source Video: HEVC, 3840x2160
   - Rate/Length: 23.976fps, 5,724 frames
   - Bitrate: 13,169 Kbs
 - [23:58:54] Reencoding: VID_00500, Pass 1 of 1
   - Error: NVENCC prematurely terminated.
   - Encoded: 3, expected: 5724
[23:59:54] - Failed video encode, aborted
The first two streams that were processed only contained a single video stream.

The fix for leading clips with no audio does fix the sync problem.
It LOOKS like that overrides "Keep HD Audio for BD25/Alternate Intact" though, outputting DTS even if the source is MA. I'm assuming it's because blank audio has to be inserted.
It might be nice to have the option to actually trim the clip from the multipart source so that isn't necessary.
Still, thank you, that was really making me nuts trying to figure out what was going on.

It shouldn't override "Keep HD Audio for BD25/Alternate Intact" -- I'll look and see there is a glitch there. A blank clip isn't added, the start time of the audio is just offset by the length of the leading (no audio) clip(s).

Is this a full or a movie-only backup?

Full UHD to BD25 (some subtitles ignored).

Just as a test, try going back to the previous version of TSMUXER4K and see if it acts differently.

Since I keep previous versions installed, I just changed the shortcut link to V*21. Unfortunately I get the same error. The only difference is that it encoded 8 frames instead of 3.
