Apply filters before resizing
Hi, SansGrip
In a precedent post you point out that split GripFit into GripCrop and GripSize allow us to apply filters before resizing. Is there some filters which are recommended to apply on the source (before resizing) when it's a DVD? |
Hi hachemoncourt,
Here's what I'm currently using: Code:
LoadPlugin("C:\encoding\mpeg2dec.dll") -kwag |
Thanx kwag,
I'll try this combinaison instead of Faery + Convolution3D But my initial question is : do we have to filter before resizing a DVD source and what kind of filter do we have to apply in this case? |

Ok kwag, that 's the way I do it :wink:

Kwag:
Code:
LoadPlugin("C:\encoding\mpeg2dec.dll") |
BlockBuster is a filter to add noise, and so is SpaceDust.
FluxSmooth is a temporal and spatial smoother, same as TemporalCleaner. Only that it looks thet the two used by kwag are working better (yields smaller file sizes). Gaudi |
Spacedust() actually REMOVES noise, Blockbuster ADDS noise.

Edit: I'll take some of that back. It really depends on the movie. I've seen some movies at 528x480 that Blockbuster does indeed help on dark scenes. So you should make a couple of test strips with and without Blockbuster and see how it compares. Specially on dark areas of a movie. -kwag |
I do everything at 352*480..which filters should I use?
I tried spacedust and temporalcleaner last night on a darker movie and it came out AWFUL! all the dark scenes looked really bad..there was noise everywhere..not as clear as I expected it should have been I make everything SVCD... I am still learning how to use all of these..... dark movie(horror movie) romance movie action movie what are the best filters for the above situations? Thanks Scott |
The filters and scripts talked about above are what you should use...
Typical Script: LoadPlugin("C:\encoding\mpeg2dec.dll") LoadPlugin("C:\encoding\GripFit_preview.dll") LoadPlugin("C:\encoding\legalclip.dll") LoadPlugin("C:\encoding\dustv5.dll") LoadPlugin("C:\encoding\temporalcleanerold.dll") Mpeg2Source("InputFile.d2v") LegalClip() GripCrop( width=528, height=480, overscan=2 ) GripSize() SpaceDust() TemporalCleaner() GripBorders() LegalClip() And you are going to get the best results using KVCDX3 MPEG-1 Template no matter if your source is a DVD or a DivX... If it still looks like crap and the movie is about 2 hours raise the CQ and split it onto 2 CD's |
Ok everybody is going to think that i'm stupid, But
I'm not really sure what NOISE means on a movie, is it actual sound or the dust around abjects. Pleas tell me |

Ok but what kind of noise is every body talking about video or audio or both, :teeth:

How do these filters increase video quality?
GripCrop( width=528, height=480, overscan=2 ) GripSize() GripBorders() LegalClip() and to these filters slow the encode? Thanks |
Hi Holomatrix,
Just like that, you'll get great quality by using the 2 blocks overscan, and your encode won't be slowed down. You're encoding a film area which won't be stretched past your TV edges, as it would if you didn't use overscan blocks. If you add filters like SpaceDust, FluxSmooth, C3D, Temporalcleaner, etc., you'll achieve even higher quality. :) -kwag |
I have been using this script for CVD encoding,
[AVISYNTH_LanczosResize_FluxSmooth_Blockbuster] 0=LoadPlugin(!FluxSmooth.dll) 1=LoadPlugin(!Blockbuster.dll) 2=FluxSmooth(^H_Value,^V_Value) 3=Blockbuster(method="noise", variance=.3, seed=1) !FluxSmooth.dll=C:\Program Files\DVD2SVCD\Fluxsmooth\Fluxsmooth.dll !Blockbuster.dll=C:\Program Files\DVD2SVCD\Blockbuster\Blockbuster.dll ^H_Value=5 ^V_Value=5 what order should I add them in then? P.S. I'm not using C3D and Faerydust because I don't see much difference and when added, they kill the encoding time too much) |
Change: 0=LoadPlugin(!FluxSmooth.dll) for: 0=LoadPlugin(!SpaceDust.dll) and give that a shot :wink:
It's much faster that FaeryDust, and you'll get superb quality. You might want to increase your variance in BlockBuster to .7 -kwag |
