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? |

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).

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

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. |

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?

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 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. |

Full UHD to BD25 (some subtitles ignored).
