[Edit] Just tried it with RoboCrop (another auto cropping plugin) as suggested by BuddTX and got the same results. Last edited by jdobbs; 1st August 2020 at 22:13. |

I'm afraid, in 2005, when AutoCrop was last updated, 10bit and 4K was far away |

@jdobbs are you using multipass ??
Multi pass frame encoding When determining the QP to use for encoding a frame, it is beneficial if NVENC knows the overall complexity of the frame to distribute the available bit budget in the most optimal manner. In some situations, multi-pass encoding may also help catch larger motion between frames. For this purpose, NVENC supports the following types of multi-pass frame encoding modes: 1-pass per frame encoding (NV_ENC_MULTI_PASS_DISABLED) 2-passes per frame, with first pass in quarter resolution and second pass in full resolution (NV_ENC_TWO_PASS_QUARTER_RESOLUTION) 2-passes per frame, with both passes in full resolution (NV_ENC_TWO_PASS_FULL_RESOLUION). In 1-pass rate control modes, NVENC estimates the required QP for the macroblock and immediately encodes the macroblock. In 2-pass rate control modes, NVENC estimates the complexity of the frame to be encoded and determines bit distribution across the frame in the first pass. In the second pass, NVENC encodes macroblocks in the frame using the distribution determined in the first pass. As a result, with 2-pass rate control modes, NVENC can distribute the bits more optimally within the frame and can reach closer to the target bitrate, especially for CBR encoding. Note, however, that everything else being the same, performance of 2-pass rate control mode is lower than that of 1-pass rate control mode. The client application should choose an appropriate multi-pass rate control mode after evaluating various modes, as each of the modes has its own advantages and disadvantages. NV_ENC_TWO_PASS_FULL_RESOLUION generates better statistics for the second pass, whereas NV_ENC_TWO_PASS_QUARTER_RESOLUTION results in larger motion vectors being caught and fed as hints to second pass. and from nvencc --multipass <string> Multi pass mode. Available only for --vbr and --cbr. [API v10.0] none 2pass-quarter 2pass-full |

History repeats .....
https://forum.doom9.org/showpost.php...ostcount=29626 From rigaya's release notes of Release 5.10: Quote:
He also wrote that in future the --vbrhq of API 9.0, 9.1 may be dropped and and only the syntax of API 10.0 will be supported. Last edited by Sharc; 2nd August 2020 at 17:50. |

CRF Prediction is broken for x265.

I had CRF Values of 1.00 but the output was not oversized ... |

No biggie really, as long as I know now that BDRB will not automatically detect the improper AR within the BDMV folder, I will just add the AVS script from now on if I have to do that. I don't do that very often, only when I have a pretty high resolution file that has the lossless audio (I know, I know... ) but I want to convert the video to a playable Blu-ray format. It just occurred to me too that maybe if I just simply imported the original MKV file into BDRB and let IT created the pseudo BDMV folder, then perhaps it would detect the non-compliant AR in the MKV file. I guess I was just trying to skip having BDRB do that step. |

Might be a display issue and an other value is used ... just see, what output size you get... |

You pretty much have to look at the output of the prediction to actually see how it went. |

On a side note, with my new build everything works really well, except when I try to utilize more of the CPU. I wonder if the Ryzen 5's are known easily to over heat? It's ONLY when I try to do an encode which of course tries to utilize most of the CPU. If it is running full out at 90%+ it gradually gets hotter and hotter until it reaches about 90 degrees and shuts the computer off. The case I got has FIVE bloody fans in it too for Goodness sake! With a huge one on the side to draw in cooler air. I'm taking it back in to where they built it, and as an added help I bought an after market CPU cooler. But, it really shouldn't be doing that anyway.
The only work around I could come up with is when I did an encode using x264 either with or without BDRB, the only way I can keep the CPU from overheating is to deselect the cores/threads in the 'Affinity' setting when you right-click the x264 process in TM. So, if I only use 1/4 of the 'cores' or whatever they are and the CPU is only running at 25%, I can just BARELY keep it under the redline temperature. Sure is frustrating. Still is a lot faster than my old one, but it would be kind of nice to be able to use the entire potential of the CPU. I'm HOPING that he will find what exactly is causing that (hopefully NOT a bad CPU!) because just adding the after market cooler alone will not fix that. I guess I'll just hafta see what happens... |

One hint I can give: thermal conductive paste, not too little, not too much... If the heat from the CPU cant get to the heat spreader you can have the best cooling solution ever but it won't cool. I, personally, use AIO watercoolers ... easy setup, lots of space left in the case, way cooler than all the aircoolers I had and not even that expensive... |
