BTW. Do you even need prefetch on such small numbers of cores? It would be funny if you got even higher fps without those extra AviSynth threads

I just stumbled over this:
http://www.chaneru.com/Roku/HLS/X264...gs.htm#threads "Default: auto (frame based threads: 1.5 * logical processors, rounded down; slice based threads: 1 * logical processors)" Could it be, that x264 is limiting itself? Should I tamper with this setting? |

Atak I believe what you're saying is true for your case your HW, and your scripts. I've never seen a script or situation where "2" was worse speedwise than no prefetch (on a dual core at least, I guess) . It's just a bit of a pain to find the "ideal" prefetch value Some people look at CPU usage, without measuring speed, it's a big mistake . Sometimes high CPU usage is thrashing, not "faster" processing or encoding |

Can you switch to avs+ in staxrip ? Worth a try . Atak is right in that something is bottlenecking in your vpy setup. |

Useful tool Atak, but synthethic tests do not necessarily reflect actual encoding performance.
If you look at avsmeter, varying prefetc, sometimes a much higher CPU% results in only a marginally higher FPS with lots of threads . That's probably similar to the "choking" you're referring to or "thrashing" I'm referring to. CPU usage% and FPS do not always relate 1:1 . Thrashing could be a bottleneck for CPU encoder. |

With the old staxrip and avisynth (the setting I used with my old computer) x264 also does stay at around 40% of CPU usage.
With the Ripbot the encoding speed is around same (~140FPS) when setting preset slower. But CPU usage is again not fully utilized. Please see image here (don't want to spam the thread) |

And with AviSynth+ it's not going really better: Image.
Contents of the AviSynth script: Code:
LoadPlugin("C:\apps\video\StaxRip2\Apps\Plugins\Both\FFMS2\ffms2.dll") FFVideoSource("C:\Users\Ezatoka\Desktop\Arpeggio of Blue Steel Ars Nova DC.m2v", colorspace = "YV12", \ cachefile = "C:\Users\Ezatoka\Desktop\Arpeggio of Blue Steel Ars Nova DC_temp\Arpeggio of Blue Steel Ars Nova DC.ffindex") #AssumeFPS(25) |

It's only 27.2 MB. I think we can handle it with today's internet speeds even in countries with ADSL only.
For comparison, Firefox installer is 50 MB and VLC is 40 MB. I don't understand the technical details maybe someone with knowledge should contact the AviSynth+ team and ask for a better installer? We don't need vcredist? Last edited by Atlantis; 7th November 2019 at 18:04. |
