I‘m currently 2-pass transcoding a BluRay and it takes about 26 hours on my 5th gen. i7.
CPU load: 100 % Is it bad for the transcode if I do some web surfing during the process. Sometimes my browser freezes for less than a second ... Would that harm my transcodes? Last edited by FLX90; 17th January 2019 at 11:26. |

If you are planning to use your computer while encoding you should even lower the priority of the process to low/idle. This way your browsing (or whatever else you're doing) will not 'freeze' and the encoder only gets the CPU cycles that are available. Of course that only works when you have sufficient memory installed.

Sounds great.
Thank you for your answer. I asked because more than 10 years ago, I transcoded my then library with iTunes to mp3. I was gaming and doing other CPU intense things during the transcoding process. After that, I noticed for 10 % of my 10,000 mp3s an audible click noise for less than a millisecond. Thought that was because of the high CPU load. |

qcomp 0.8 is part of --tune grain so it's not anything insane. We usually don't recommend users to fiddle with those parameters because they don't really understand them and are better off simply using preset+tune than choosing "wrong" values.

Does anyone have inisight on how x264 uses NEON instruction sets?
I just upgraded from a mobile device with 8x symmetric Cortex A53 to 4xA53 slower +4xA72 faster that has more or less the same multicore performance for a majority of tasks However I noticed that x264 has had more than a 2x speedup on this device Does Cortex A72 come with some special vector magic it uses? |

I've been experimenting with going back to x264 for some of my BD re-encodes where the source is rather soft or noisy/grainy. I'm having a hard time figuring out when one would need to tweak psy-trellis. I understand that psy-rd is mainly responsible for keeping the grain, or at least fooling the viewing into believing that there is detail there, but I don't know what psy-trellis adjusts. Can anyone explain any use cases?
