There's a lot of other good stuff added between 3.0 and 3.4, though! https://x265.readthedocs.io/en/defau...easenotes.html |

If you set them to the same values the reuse function should work like before. Last edited by Greenhorn; 28th June 2020 at 10:18. |

So x265 3.4+9, they "fixed" --hist-threshold to avoid false positives. However it seems to do much worse than before (as well as 3.4+7, where they fixed the false positives).
I'm getting less I frames with --hist-threshold 0.005 (default 0.03) than the default scenecut algorithm.. Maybe my sample clip is not colorful enough.. Last edited by quietvoid; 1st July 2020 at 01:07. |

Fewer I frames isn't problem in itself. The question is if it is not flagging edits and such as IDR. Beyond that, IDR and I should only be used when it improves compression efficiency, or as needed based on --keyint. |

From what I understand, detected scene cuts should start with an I frame, as it is how adaptive keyframe placement works. |

Does analysis-save always write such huge files at values above 1? I tried a 128MB sample file and it created a multi-gigabyte save file (writing at 60mb/s which significantly slowed down the encode).
Also, it only seems to work with ref=1 in the second pass if you are using --no-slow-firstpass , otherwise I get: Error reading analysis data. Incompatible option : <ref> This is with x265 3.3+5-g4a0cef17d+32 and 3.4+9-g1fb7c7960 |
