When you create the ALTERNATE output, the audio stream existing in the pseudo-BD structure (AC3) is the one that is "kept intact". |

If you were to code wrap the text, instead of quote wrap it, it would show up in this quoted post.
That said, 23.976 fps is being passed to the x264 encoder. The resulting C:\WORKING\WORKFILES\VID_00263.AVS.264 is not (according to mediainfo)? |

It depends on the usage. If you are trying to create a blu-ray disc, EAC3 without core audio is not compliant for the primary stream. That's because EAC3 (DD+) support is optional in a blu-ray player, (AC3 support is required). The way the standard ensures support is by requiring EAC3 to have standard AC3 embedded in the stream as well (core audio).
The main advantage to EAC3 is its ability to support more channels. Standard AC3 has a limit of 6 channels (e.g. 5.1). EAC3, for example, could support 7.1. EAC3 also supports higher data rates. In BD-RB, since all sources are either imported or come directly from a BD source, an imported EAC3 source would almost always be converted to AC3. There are several reasons -- including the requirement for a "core" audio to be included -- which pretty much never exists in an import source. Now... which is better? Since Dolby's double blind tests show that a 5.1 AC3 stream encoded at 640Kbs is indistiguishable from an uncompressed source (to the human ear) -- it is debatable whether EAC3's higher bitrates actually provide any useful value. If you need 7.1 for some reason, then maybe... but since a sound mixed on both the front and rear channels of a 5.1 source gives the appearance of a side channel -- it's also debatable as to whether 7.1 is anything more than a marketing gimmick. Others disagree on that -- so what I've stated is nothing more than opinion. Last edited by jdobbs; 16th April 2021 at 22:27. |

To answer the "aside" - partly familiarity as I used MultiAVCHD for some other projects that didn't need re-encoding and/or weren't SD content before finding BDRB; and coupled with that - the disc menu is (I think) somewhat more configurable. Indeed the only time I attempted to get BDRB to build its own menu I got a nice background and title card music, but no actual text or highlightable/selectable controls. That was a while back and I no longer have details of what it was I was doing at the time. |

Remember forum rule 12:
Quote:
Out of BD rebuild there are other opinions: 1) About more channels than max 5.1 supported by AC3: Quote:
2) About bitrate I agree with jdobbs when say: Quote:
1) Support not only more channels than AC3 but also surround 3D with Atmos, not allowed for AC3. 2) The encoder is more efficient and we can obtain more quality with less bitrate, like we can see in a multichannel test. The DD+ (EAC3) 448 Kb/s is comparable to DTS 1500 like AC3 640 Then, if device player support all EAC3 features, EAC3 is better.

Confirmed using GeForce experience that driver is current - NVIDIA studio Driver v462.31 (14 Apr 21) was installed just prior to these tests. Tests using a previously attempted single .mkv as the source. 1: add NVENC_NO_FRAMECHK=1 to .ini file at the last line BEFORE [paths] Launch BDRB and backup. Outcome: NVENCC prematurely terminated (at ~79%) (Encoded 72102, expected 90127) Just in case it was a typo 2: Exit BDRB add NVENCC_NO_FRAMECHK=1 to .ini file at the last line BEFORE [paths] Launch BDRB and backup. (Do not resume job; empty working folder) Outcome: NVENCC prematurely terminated (at ~79%) (Encoded 72102, expected 90127) 3: revert above change. Add IMPORT_VFR_SCAN=1 to .ini file at the last line BEFORE [paths] Launch BDRB and backup. (Do not resume job; empty working folder) Outcome: NVENCC prematurely terminated (at ~79%) (Encoded 72102, expected 90127) 4: After the last fail (i.e with the last change to .ini still in place), copied & pasted the contents of LASTCMD.TXT into an elevated command prompt LASTCMD.TXT ========== "C:\Users\nigel\Downloads\BDRebuilder\tools\nvenc\nvencc.exe" --avhw --fps 29.97 -i "C:\USERS\NIGEL\VIDEOS\NVENCC TEST\IMPORTS\GFU_FOR_NVENCC_TEST_COREL\BDMV\STREAM\00000.m2ts" --codec h264 --preset performance --bluray --qp-min 0 --vbr 2327 --aq --aq-temporal --keyfile "C:\USERS\NIGEL\VIDEOS\NVENCC TEST\WORKFILES\VID_00000.CHP" --sar 10:11 --aud --pic-struct --vbv-bufsize 13000 --max-bitrate 15000 --gop-len 30 -o "C:\USERS\NIGEL\VIDEOS\NVENCC TEST\WORKFILES\VID_00000.AVS.264" ========= DOS output ========= Microsoft Windows [Version 10.0.19042.906] (c) Microsoft Corporation.

Same outcome. Quote:
Dumb thought: I edited the .ini file after first making a backup copy of it in the same folder (with a different name). I'm going to do 1 and 3 again after first putting the copy somewhere else entirely. Back in a jiffy. Last edited by RetsimLegin; 17th April 2021 at 14:01. |

glitch on conversion with nvenc activated
i make two processing, one with nvenc activated and the second with x264. On nvenc, there are glitches on some frames.
but on x264 is working fine. can you check this?? i make on Sonic The Hedgehog bluray to bd25. i check others conversion make with nvenc and all have frame glitch. |
