Is MULTIPROCESS setting even needed anymore as I seem to recall that both x264 and x265 and multi-threaded by default?
Also I noticed that some rebuilds the extras are not using Quicker for extras CRF setting as likely not identified as extras since the file size of some extras can match the episodes/movie due to length. Is there a way to force a CRF per title or mark certain streams as extras? |

Also for MULTIPROCESS=4 with my 6 core/12 thread CPU I am seeing CPU utilization pegged at 100% where without the CPU usage never goes above 30%. Seems it would be much faster with the setting. Does the splitting of the parts into 4 per movie add more time than the Multiprocess gains would give? Last edited by jfcarbel; 5th February 2020 at 06:01. |

no matter what MULTIPROSESS setting I use n, 6, 2, I see no difference in first pass encode, my cpu is working anywhere between 87-100% giving me 6.50X speed ( pass 1 ) no matter the setting in resorce manager it shows all cores and threads at 87-100 cpu usage Last edited by Mike-uk; 5th February 2020 at 12:27. |

Interesting. No. I don't believe the splitting would add anything more than a negligible amout of time. Glad you told me. I wasn't sure if anyone was using MULTIPROCESS. |

I am going to do a test on my 6 core to compare. I had heard that about 4 for MULTIPROCESS does not make that much difference but never really tested that.
I also have a Ryzen 3900X build coming so be interesting to compare the 2 platforms. |

Maybe qaac is better for low bitrates, but for NeroAAC quality 0.5 is not possible ear differences with same size than qaac.
NeroAACenc.exe can be distributed (or linked) without copyright problems. qaac need a instalation process not easy to override copyright. If low bitrates are desired maybe the free opus is the best option.

I installed BD-RB on a new Windows 10 box. After starting the program I got the message "Your Windows 7 system has been succesfully configured to use LAV with BD Rebuilder". Is BD-RB not recognising my Windows 10 system correctly?

Slow frame rate doing uhd disk
I just put together a PC with a AMD Ryzen 3900X processor and currently trying to shrink UHD Aladdin to a 50GB disk. Why is my frame rate only 2-3 frames per second? I do have it set to do the highest quality. With this same settings on other Blu ray's I get frame rates around 40 frames per second?

So are you saying that the hardware encoding will not give as good quality as software encoding? The whole idea of wanting to go to HW encoding is speed, but I also want good quality. I don't want to spend hundreds of dollars on a new video card, and find out that the "best" it can do in HW encoding, is similar to the SW encoding "fastest speed for X265". Even though I have a relatively new, GTX 1050 TI, it sounds like I would need to upgrade again, to take advantage of all the latest HW encoding options. So am I understanding this correctly, that with HW encoding, there are limited options for video quality? If that is the case, HW encoding does not interest me as much now. Of course, we all want speed, but quality is very important to me also. I would not mind a "several hours-half day-similar time" encode, if I could use HW encoding and also use the "ENCODE_QUALITY=4" setting. Thanks! |

Hey mate, depending on what card you have, NVENC can perform as good as Slow on the right bitrate. Pascal and Maxwell cards don't beat x265 Faster. However Turing cards do. Turing cards in H.265 get much closer to Medium and Slow on x265. If you have a Turing card, and you use FFMPEG with some good options like -g 240 and spatial adaptive quantisation, you can basically get anything x265 can get. Some settings will still use CPU for rc-lookahead and the 2-pass preset "slow", but in terms of speed and quality Turing is the way to go now. Last edited by Mike-uk; 10th February 2020 at 12:49. |

Given a high enough bitrate -- almost anything can give excellent quality. But at a given bitrate, you'll be hard pressed to find any solution that can beat X265. When backing up a blu-ray the average bitrate is fixed based upon the target size and the length of the source. While I haven't done any testing, I have doubts that a hardware solution could match it.
With that said... the bitrates are typically pretty high in BD backups, and its debatable whether most people would see a difference. Last edited by jdobbs; 10th February 2020 at 14:26. |

Thank you Mike-UK and JDobbs!
Mike-UK, I have a GTX 1050 TI, and that apparently does not have Turing, and am not anxious to upgrade my video card again! My 9 year old PC is still a workhorse, (6 core Xeon processor (12 threads with Hyperthreading), 24 gig RAM, 2 SSD HD, 2 physical HD), and was hoping to wait a few years before upgrading, because no matter what I buy, two years down the road, it is "not the latest and greatest!"

To increase the frame rate I tried 2 things, I added the option MULTIPROCESS=12 because I have the AMD Ryzen 3900X cpu which ended up changing nothing, frame rate still 3 frames per second. Then I changed the encoder settings to High Quality (default) and now the frame rate changes to 6 frames per second. Is there anything else I can change to increase the frame rate other than changing the encoder settings to a lower value?
