that was ages ago. the fast p-skip was then tweaked by the x264 devs coz there was that blocking issue. after the tweak, the blocking is almost non existent and --no-fast-pskip is pretty useless unless you're using insane options.

I plan on doing a test with the 1080p Blu-ray of 30 Days of Night (quite grainy, dark, etc.) once we narrow down the possibilities with this This source is IMO as ideal as a single source can be, but still only 1 source.
And again, I don't think people are noticing, you can download the encoded videos, I put links in the first post. These frames were just examples. |

yep it's very useless this way motion results and their speed/quality/complexity/size have to be taken into account to imho
very nice you can see what --no-fast-pskip does in a extreme low bitrate situation you gonna see that it creates a complete different look in such situations though for high bitrate you wont realize any difference you can either chose between more detail though also more motion artifacts or less detail no artifacts then

Okay, lots of new --psy-rd values. Please cast your vote starting now, and reasons! (just post)
I highly advise downloading the actual encoded videos and taking a look, as one frame can only do so much. Once I have some top values, I'll do a test with 1080p grainy Blu-ray footage. My vote now goes to 1.15:0.7. EDIT: Actually, while 1.3:0.5 has more edge crap and slight smoke banding, it does far better on the back wall IMO... check the shadows, compare those two against the source. 1.3:0.5 preserves the original shapes better.

1.15:0.7 while looks sharper have more ringing and chroma artiafacts that 1.0:1.0. Maybe impression of sharpness is from ringing noise.
Edit: 1.15:0.7 actually saves more details, but I don't like that ringing. Last edited by Quark.Fusion; 18th September 2008 at 08:55. |

Code:
OPT("psy-rd") { if( 2 == sscanf( value, "%f:%f", &p->analyse.f_psy_rd, &p->analyse.f_psy_trellis ) || 2 == sscanf( value, "%f,%f", &p->analyse.f_psy_rd, &p->analyse.f_psy_trellis ) ) { } else if( sscanf( value, "%f", &p->analyse.f_psy_rd ) ) { p->analyse.f_psy_trellis = 0; } else { p->analyse.f_psy_rd = 0; p->analyse.f_psy_trellis = 0; } } But to answer audyovydeo's question, yes --psy-rd 0 is eqivalent to --psy-rd 0:0
