I'd agree to Selur's opinion, it seems to match the documentation: complex analysis "Increases the RD level at points where quality drops due to VBV rate control enforcement", therefore it should be more effective when it was initially rather low. It compensates a bit of the loss in fast presets.

Hi, i do my encode with a command line like this
Code:
vspipe.exe -y script.vpy - | ffmpeg.exe -i - -c:v libx265 -preset veryslow -crf 22 ... If i should dither it on the script side, what kind of dither is it best for this kind of parameters, if i'm not mistaken ordered dither should be the best when reaching for low bitrate target in every case Code:
rect=0:amp=0:cutree=0:early-skip=0:limit-refs=3:aq-mode=3:limit-modes=1:level-idc=4:me=2:fast-intra=1:max-merge=3:rd=4:rdoq-level=0:psy-rd=1.1:aq-strength=1.9:deblock=-1,-1 |

Is there a way to convert bt2020 to bt709 color matrix?

Did you try whether this Bitrate Viewer fails when you have HEVC multiplexed in a supported container? It may just not support a raw video stream as long as there is no matching source filter.
An alternative may be to let x265 write a verbose CSV log (csv-log-level > 0), import it into a spreadsheet calculator, sort it to display order (that's a bit tricky e.g. in Excel alone), and let this draw a graph. |

LigH, ApTeM thanks a lot for your advices, but.. it will difficult ways for me.
In the both cases for AVC and HEVC I use mkv container. With AVC in mkv "Bitrate Viewer" works perfect, but with HEVC in mkv I got error "Codec not found". LAV Filters 0.69 was installed. |

Oh, I think I remember that this Bitrate Viewer was built upon some ffmpeg version which is quite outdated today... It will not use LAV Filters. No source available. No longer developed.
Here was the forum thread with my old complaint... The author updated only a Mac OS X version, but not a Windows version. You will find some more tools there, but they are command line tools, not so user friendly without mouse support. Last edited by LigH; 1st February 2017 at 15:52. |

Oh, thanks! I used CheckBitrate from https://onedrive.live.com/?authkey=%...DD4375AC8933C6 and got csv-file.
