Is this a regression of 2.0? It reminds me of the problems with tune grain. Wondering if they are related.

@divxmaster: Thanks for sharing your experience with pre-sharpening. I've browsed the complete list of AviSynth sharpening plugins/scripts, and will test some to see the results on both sharpening and resulting bitrate (whether image complexity increases as well). For now, "adaptive" sharpening seems to me as the most appropriate direction to go. I've started using Lanczos4resize which improves sharpness (though it introduces halo as well, unlike Lanczos3). Also, decreased deblock from -1 to -2, and am currently testing -3 as image quality improved after I discarded qg size 16 parameter and artifacts stopped "accumulating" in smaller image blocks containing sharp, pronounced details where they were overly visible.
I compress using modified "slower" profile - me star, subme 7, rd 6, ref 6, bframes 9, aq-mode 2/strength 2, psy rd 2, psy rdoq 1, no rskip, rect, no sao, no strong intra smoothing. Speedup options are limit modes, limit refs 3, no weightb, no amp, max merge 2. |

While I haven't done many encodes using aq-mode 2 or 3 - it seems to be 25-35% slower. thanks, |

Im looking for a software that would display what encoding parameters were used. Can someone recommend one? Sometimes mediainfo doesn't show what parameters were used. Or this was intentionally deleted by the encoder?

Furthermore, it is important to point out that larger bitrate itself means slower encode, when you have more bits for CABAC entropy encoding. |

^ littlepox: And decoding higher bitrates can be slower too (compared with otherwise similar complexity).
_ @ Magic Mark: Not all encoders of the same target format may support storing encoding parameters as auxiliary data; there are more HEVC encoders than just x265. Also you can disable x265 writing them into the video stream (--no-info). Some parameters could be analyzed from headers or GOP attributes. But others would be hard to discover from the video stream only. Last edited by LigH; 22nd July 2016 at 07:18. |

I think there is some error in your compile, for the last binary you uploaded (2.0 - 8). Using it, I kept getting an error towards the end of the 2nd pass. (Error writing trailer of pipe.) Googling it suggests that it somehow relates to ffmpeg. But I don't get that error with the binary from x265.eu. (I've only tried 2.0 - 5.) Same settings and same media file, of course.

Thnx for the info Ma, but it looks like that issue was set to 'Resolved' a couple of days after it was reported.
EDIT Ahh..... It's a GCC 'issue'. Don't have a clue on how 2 fix that in the media-autobuild_suite. Last edited by Barough; 22nd July 2016 at 14:48. |

@Barough
see last message here : https://github.com/jb-alvarado/media...ite/issues/358 It give you an example how to do this |

@ easyfab
Thnx for the info/reply. I had a look @ it but i've never done any modifying like that. I have basically no knowledge when it comes to that kinda stuff. That's why i went for the media-autobuild_suite. Last edited by Barough; 22nd July 2016 at 18:42. |

I've attached workaround for 32-bit GCC (it sets "-march=pentium4 -mtune=generic" as default for 32-bit GCC).
To apply this patch in x265 folder you can: save attached '32bit.txt' to x265 source file folder on your HDD; from x265 folder you can execute: patch -p1 <32bit.txt exclusive or (if you don't have patch command): hg import --no-commit 32bit.txt To clean x265 source code (from this patch for example) you can execute: hg update -C |
