Sharktooth,
Thanks so much for all your hard work; the presets are indispensable! Sorry about your computer issues. I had a couple questions about the new presets (V.52), specifically the Unrestricted 1pass Constant Quality preset. 1) I may have misinterpreted something along the way but it was my understanding that Trellis 1 was not compatible with the new PsyRDO. I know PsyRDO automatically turns off Trellis 1 if detected but is Trellis 1 still the official "Recommended Value" for Constant Quality? 2) It appears you have modified quite a few of the presets' Deblocking values. I just wanted to confirm that you didn't mean to change the "Recommended Value" for Constant Quality. 3) Is there a specific reason that "No Fast P-Skip" is unchecked in all of the 1-pass presets? Thanks again for all of your effort!

1) right. x264 will automatically disable trellis if set to 1 and if psy-rdo is enabled. if the preset contains trellis 1 then it's an error. Trellis with Psy-RDO can be only 0 or 2. 2 is better but slower.
2) i modified all the -2,-1 in -1,-1 since i've seen some slight more oversharpening when psy-rdo was introduced (i've changed monitor too in that period, so it may be also due to that). 3) fast pskip is an optimization, i wont use no-fast-pskip in non insane profiles.

Sharktooth,
Thanks for the quick reply. FYI, I'm getting a 404 error on http://mirror05.x264.nl/Sharktooth/M...ofiles_v52.zip Looks like the URL still references the previous version (v52).

Thanks Sharktooth.
By the way, I primarily do CRF encoding using the Constant Quality preset. I would like to experiment with some of the other presets using Constant Quality. I know you recommend using "Spatial" for B-Frame Mode in CQ. So I would assume that I should change B-Frame Mode to "Spatial" when using a 2-pass preset (e.g. "Insane") in CQ mode, correct? Thanks again!

Auto is not good for 1 pass (CQ, CRF or ABR). Spatial seems better to me...
However the Unrestricted CQ preset is quite good. There are very few other options to tweak to rise compression/quality. Just set your preferred CRF and let it go...

not much better but at least i can see/read/type a bit better now
feel free to test the new presets and to report problems, inconsistencies, etc...

What do you mean by oversharpening? If it's more detail then wouldn't 0,-2 or 0,-1 be better (if you're purposefully avoiding default 0,0)? Quote:
Additionally, merange 32 seems suitable for Unrestricted 2pass Insane. Finally, how difficult would it be to create a quality slider in MeGUI based on these (and perhaps more fine-grained) profiles? Last edited by Avenger007; 24th July 2008 at 23:44. |

I just like how you've limited the choices. I'll definitely try out the new CQ profile. Maybe you want to make the new default for Keyframe Interval and Min GOP Size 240/24, but you already told me before it doesn't matter a great deal.
Heh Insane is quite funny, even Turbo is off ;p Last edited by JarrettH; 24th July 2008 at 23:44. |

@avenger: no-fast-pskip is a non issue. it will stay on on Insane preset, but the other really dont need it.
i corrected the deblocking in Unrestricted CQ and will post an update. with oversharpening i mean the encoding looked too sharp (maybe the psy-rdo effect or maybe it's just due to my new display) so i decided for -1,-1 instead of -2,-1. The difference is negligible though. concerning the quality slider bar post the idea in the megui feature requests tracker. @JarrettH: the GOP size should be proportional to the source framerate. if you live in a NTSC country you can safely use 240/24 (for 24FPS) or 300/30 (for 30FPS)... for PAL, 250/25 (25 FPS). The presets are not absolute, you may always adjust them for your needs. I live in a PAL country so i set 250/25 by default but no one said you cant change those values.

I am thinking about stopping the encode when I return and starting again. What may happen, if I don't have a proportional of 23,976 (240/24) ? Do you think it's worth a try and letting the machine run ? Thanks in advance. |

it's not a big problem. using bigger GOP doesnt mean having less quality. it could even be the opposite.
Keyint = 10 x FPS and Min GOP = FPS is just a common sense rule... but not mandatory. keep your encode, you wont notice any difference.

Question: what's roughly the oldest kind of card to support DXVA?
Another one: if encoded with DXVA profile, I assume it will still play on PC with non-DXVA card, only it will be slow? Gonna test tonight thanks for all the work. |
