I'm sure everyone is waiting for your new kvcd template and have already fallen off their chairs waiting :grrr:. And the way it sounds your getting there. :lol: Keep up the great work. |
@Boulder,
With Tmpgenc --> Settings --> Video Settings try setting P_Picture Spoilage = 0 and B_Picture Spoilage = 0. This I understand (as SansGrip says) improves file size. I don't know why, but when I tried this and it worked. :) -black prince |

Hello everybody,
Here's another short sample (extremely high contrast scene) from K-Pax, made with the new parameters: http://www.kvcd.net/kpax-newgop-newmat.mpg (no audio) K-Pax is 2 hours and 40 seconds. That's what it looks like on one CD-R at 528x480 with audio at 112Kbps. CQ used was 71.3. :wink: -kwag |

I'm not sure we'll ever be able to get rid of that pulsing completely, since if you single-step through each frame of any MPEG-1 stream you'll see that the I-frames are much blockier than the P- and B- frames, which is why we get a pulse every time the I-frame comes around. You can see it even on completely standard VCDs. That's one area where MPEG-2 wins -- its I-frames are much less blocky. I'd be really interested to see the same clip done with CQ_VBR and Blockbuster method="noise" (maybe variance=0.7 or so). Maybe that would get rid of the little bit of blockiness, but how much Gibbs would be introduced? |

Both clips were made with this script: Code:
LoadPlugin("C:\encoding\MPEG2DEC.dll") -kwag |

I don't know how it will look at 352x240. I haven't tested that yet. But I saw K-19 on my HDTV and it looks by far better than every previous matrix or GOP :wink: So for 528x480, New GOP + CQ + BETA-1a Notch Matrix wins by far :D -kwag |

CQ_VBR=60. Here's my avs script: mpeg2source("D:\Temp\movie.d2v") LegalClip() # GripFit( source_anamorphic = true, dest_anamorphic=false, width=352, height=240, overscan=1) # opening=Trim(0,3093) opening=opening.TemporalSoften(3,8,30) # movie=Trim(3094,145515) movie=movie.Blockbuster(method="noise", variance=.5, seed=1).FluxSmooth() # credits=Trim(145516,0) credits=credits.Greyscale().TemporalSoften(3,8,30) # last=opening+movie+credits # LegalClip() # #Sampler(length=24) At 352x240 it's very hard to detect flashing unless I got right up to my PC. At higher resolutions (e.g. 528x480) it more noticable. There was hardly any noticable blockiness probably due to Blockbuster noise. The picture was softer looking so that Gibbs noise wasn't noticable. I wanted to sharpen the picture just a little without dramatically increas- ing file size, anybody have suggestions. From 5+ feet the picture is very good. I'd say there was an improvement from the older GOP and standard Q-Matrix. File size with the new GOP and Q-Matrix has decreased :D -black prince |

So is the template ready to release to the masses?
or Does more testing need to be done? |

yes,i want to know too! :) |

a few feet and still see flashing. SansGrip has a point about MPEG-2, that there are really two compressions taking place for I, P, and B frames. The blocks are compressed as well as the entire frame itself. Your latest adjustments to GOP and Q-Matrix has made a noticable decrease, which leads me to believe there still possibly a solution. At high CQ or CQ_VBR, Gibbs noise seems to be almost gone. If it weren't for flashing this would be equal to DVD quality. :wink: -black prince |
