I'll take a look at it. It's actually measurably faster? That surprises me. Last edited by jdobbs; 15th November 2020 at 17:43. |

I create the structure with tsmuxer and record to disk. I reproduce them perfectly on xbox series x. if you could add the option to disable it in hidden options it would be perfect. thanks for answering |

Multiprocess
@ JD
Since 0.61.18 doesn't support MULTIPROCESS still... I noticed something very interesting.. I imported an MKV (1080p) that BD-RB (0.61.13) made for me a bit ago. I wanted to rerender it from 23GB to 10GB or so..check some Screen Sharing with my Android and my HDTV. Using 0.61.13 because MULTIPROCESS functions with it, I had BD-RB import the MKV..went well.. It created: Movie name (Root) BDMV CERTIFICATE PSEUDO If I leave PSEUDO there, the split won't happen for the rerendering process. It just goes into single rerendering process. If I delete it or rename it it will MP. I don't have to reload anything, just rename in some way then click Backup and click No on resume, Delete All Old Files. Heh, I tried this with latest version and this doesn't work. Figured I'd give it a try.

It is possibly an NVEncC limitation or a bug, because I can produce interlaced encodes (TFF, BFF) with ffmpeg using NVEnc (h264_nvenc). Edit: Now it seems to work with NVEncC for my 'ancient' Pascal 1050ti GPU, after removing the '--multipass 2pass-full' and '--bref-mode middle' from my commandline. Current commandline for interlaced encoding (probably still much overkill for the new presets): Code:
NVEncC64.exe --avsw -i "%~1" --codec h264 --profile high --level 4.1 --lookahead 32 --vbr 0 --vbr-quality 22 --aq --aq-temporal --aq-strength 4 --gop-len 24 --ref 4 --nonrefp --bframes 3 --mv-precision Q-pel --preset quality --bluray --interlace tff --max-bitrate 40000 --vbv-bufsize 30000 --output "%~1_NVEncC.m2ts" Last edited by Sharc; 24th November 2020 at 15:42. |

Here's an interesting aside that I found while doing a little testing.
As you might expect, CQM (NVENCC) and CRF (X264) are not exactly the same -- but they use similar concepts. What I've found, by performing SSIM tests, is that a CRF of 23 is not equivalent in quality to a CQM of 23. In fact, in order to get approximately the same SSIM (perceived quality) output of a CRF=23 encode you would use a CQM value of 25.5. By adjusting this it also brings the sizing a little closer. So to get a similar quality output an NVENCC encode (CQM=25.5) the size of the output is only 1.338 times larger than that of X264 with CRF=23. That's really not bad considering the enormous speed advantage. This testing was done on a Turing based NVIDIA card (GTX1660). Cards that don't support B frames would probably see different results. Tomorrow I may set up some tests to find the equivalent CQM quality values for each of the whole number CRFs. |

Blank one or more items, enter Setup and change one or more settings (a resizing one, for example). Blanked items are reset back to non-blanked.
Also, blanked items are not remembered when closing/opening BD-RB. It'd be nice to have this remembered even without saving the project.

Yes. Using 5 is a lower quality setting than 1 (5 uses x264's "ultrafast" preset while 1 uses "faster") -- but, the question is whether you can even tell a difference on a 25GB disc. There's also a setting between the two (0) that will use "superfast".

@jdobbs
Is there any hidden option to demux all files then stop ? (Instead of demux file 1 -> rebuild file 1 -> demux file 2 -> rebuild file 2->...) I would like to have this option in order to replace some subtitles. |
