I'm hoping that a set of "standard" values will be agreed upon which can then be incorporated into a C3D-style preset parameter. Quote:

Thanks again for your persistence. Testers like yourself really make it easier for the developer to improve the code, and knowing someone is testing the limits of the filter makes one actually want to stare at the source for a dozen more hours improving it :). |

On the other hand I respect Kwag's opinion greatly, and I tend to believe him when he suggests that perceived quality is superior with bilinear and a selective sharpen. |
Ok, thanks. This is the script I am going to try in DVD2SVCD:
[AVISYNTH_BlockbusterBilinearResizeNoMoSmooth] 0=BilinearResize(^TargetWidth,^TargetHeight) 1=AddBorders(0,^BorderTop,0,^BorderBottom) 2=LoadPlugin(!Blockbuster.dll) 3=LoadPlugin(!NoMoSmooth.dll) 4=Blockbuster( method="noise", detail_min=1, detail_max=3, lv=1.5 ) 5=Blockbuster( method="sharpen", detail_min=4, detail_max=99, strength=^StrengthValue ) 6=NoMoSmooth() !Blockbuster.dll=C:\Program Files\DVD2SVCD\Blockbuster\Blockbuster.dll ^StrengthValue=20 !NoMoSmooth.dll=C:\Program Files\DVD2SVCD\NoMoSmooth\NoMoSmooth.dll Should I put some values in for NoMoSmooth or just leave as is? Thanks |

You might also want to try a compromise, such as bicubic 0/0.5 or 0.33/0.33. The latter was declared "most preferred" after tests conducted by the algorithm designers on human subjects ;). |
Hi SansGrip,

my picture quality seems too sharp. Since I encode from DVD source 720x480 shouldn't I use bilinearResize going to 352x240? I believe bilinearResize and Blockbuster-noise-sharpen produce a more pleasing picture image in my opinion. :) NoMoSmooth is using default settings, so I'll wait for Kwag to tweak this filter. 8) -black prince |
Ok, ran my test clip, looks good but I see to much Mosquito noise, should I make a change to my script? or add the UnDot filter?
Thanks |

Shoot, sorry, I ran it through DVD2SVCD and used CCE, forgot to change the encoder to TMPEG. I will set it up using your LBR 352 X 480 (CVD) template settings and see how it goes. By the way would these settings work with your 1 CD 704 X 480 settings? I loved the sharpness and crispness I got with this template but ofcourse lots of blocks. Would these filters remove the blocks but keep the sharpness at this resoulution?
Thanks |

I also used the default value of 1 for luminance, instead of 1.5, as I had posted before. Then I changed the "sharpen" method to start at a complexity level of 20. Why?, because we don't want to sharpen low lit things close to the boundaries of the DCT blocks on dark scenes. So I started the sharpen filter from 20 up to 90, and left the last ~10% ( 91 to 99 ) untouched. Why?, so that the sharpest edges, highest frequencies, don't get sharpened at all. So this should kill some high frequency "Mosquito Effect" Feedback welcome how can i "turn" this to load in dvd2s(K)vcd? and how can i load the new templates in dvd2s(K)vcd? :? thanks in advance! :wink: |

For some reason I haven't been able to download your test samples. I keep getting bad link errors i.e. "The page cannot be displayed"
In any case are you using your monitor as the quality standard ? With one of your old scripts from yesterday, fiddler on the roof looked okay on my monitor but great on my tv, except in a few dark areas (a lot of blocks on a sun rising scene) . Also that annoying periodic speed up or slow down thing with my dvd player stopped, is that due to the new GOP structure ? I think I am going to try your new filters on crouching tiger hidden dragon. |
Hi LadyMiles,
Are you trying to download the samples from this thread? http://www.kvcd.net/forum/viewtopic....r=asc&start=30 I just tried, with "Right Click, save as..." on a link, and it works. -kwag |

"...ok Kwag ,but this script i can't make. it's confuse for me..." It"s already posted by Dagaar on page 5 of this thread. Have a look there... :) |

ok,thanks, but what about this posted by Kwag? BB_Resolution = 352*240 #BB_Resolution = 352*480 #BB_Resolution = 528*480 #BB_Resolution = 544*480 #BB_Resolution = 704*480 BB_StrengthConstant = 352 * 240 * 20 # Base strength StrengthValue = round (BB_StrengthConstant / BB_Resolution) Blockbuster( method="noise", detail_min=1, detail_max=10, lv=1 ) # Apply noise if complexity is <= 10%. Blockbuster( method="sharpen", detail_min=20, detail_max=90, strength=StrengthValue) # Sharpen only if complexity is >= 20% AND <=90%. how can i put this it in the script? it's possible? thanks in advance! :wink: |
jorel,
BB_StrengthConstant = 352 * 240 * 20 # Base strength StrengthValue = round (BB_StrengthConstant / BB_Resolution) The above 2 lines calculate the right Strength value for a given resolution. Eg for 352x240 it"s 20. Calculate this value manually for your resolution and set it in the Frameserver tab. |

Is blockbuster good for anime ? If not what filters should be used.

I have a pretty strong hunch it would work well on solid-colour cartoons, though. |
