You're using too many reference frames. 16 is way too much, even for anime encodings. Good values for feature films/film series is between 4 and 6. Anything higher is not beneficial and can actually degrade quality for live action content. For anime, you can up it by 2 more
As for comparable settings for x265, that'll be ref=6:subme=5:rd=6. However, there are other things to tweak like psy-rd and psy-rdoq. I like using high values for these options (psy-rd=4 and psy-rdoq=16). A qcomp of 0.7 is also nice. Also, using aq mode 1 seems to give most of the time the best subjective quality. The other aq modes are too unpredictable and some just waste bits for no apparent image improvement Last edited by microchip8; 26th November 2020 at 14:19. |

You should do a test-encode first (I prefer lower psy-rdoq), write this in your Avisynth+ script to only encode the first 1000 frames:
Trim (0,1000) BTW, I tried setting a higher --ref than 6 in x265, but x265 showed error and exited. |

1)There is a lot of information on the web that the H. 264 or H. 265 format can be opened by programs for Windows.
I had to spend a lot of time to download and install all this software. As a result, no application was able to play the video in part 264. How can I open the H264 file from a surveillance camera? |

Surveillance camera makers often have proprietary codec implementations.
You have to install their codec on your system. Throw the offending file on mediainfo, note down the fourcc. (Geovision MPEG-4 AVC coming into my mind, I had to do the same, going to their website, download and install their codec).
