Suggestion for DVD filters?
Hi there,
I would like to have a suggestion on the filters (and its properly order) for KDVD (full-D1). I am wondering if it is worth to use filters like SpaceDust(), because it is reported that it takes much longer. I am currently only using Fluxsmoother and Legal Clip. |

For KDVDs, you're already encoding at a very high resolution, so take it easy on the filters :D Use Legalclip, mergechroma(blur(1.5)) and spacedust. That should be enough for KDVDs :wink: SpaceDust is very fast, compared to PixieDust or FaeryDust. -kwag |
Thanks Kwag, I will try and report the result.

Thanks, I was going to post the same question today.

Hi there,
I tried the combination suggested by Kwag (i.e. LegalClip, mergechroma(blur(1.5)) and spacedust), the result was pretty good, it is definitely better than before (just LegalClip and FluxSmoother). I am wondering if FaeryDust is better than SpaceDust? If so, how much longer will FaeryDust take compare with SpaceDust (in terms of percentage, say 30% or more)?? Thanks in advance. |

I have a similiar question. My goal is to use my DVD's and a replacement for the 2 cd encodes, but I am trying to get approx 3 encodes (6hrs max) per DVD. (I.E. 6 cds). Each encode is approx. 1.43Gb in size (w/ audio) or 1.25Gb (w/o audio). Presently I am using mergechroma, spacedust, and temproalcleaner. I am doing an encode right now replacing temporalcleaner with peachsmoother. Most of my sources are DVD. Should I use Half D1, or Full D1 with thes constraints, and which filters should I use for each template. BTW, I usually do most of my encodes at 16x9 and FullD1 right now. Would I gain anything using HalfD1 (CQ?). I also have just a standard TV not a widescreen TV. Thanks Racer99 |
Hi Racer99,
I would just use MergeChroma, PeachSmoother (I'm using that too :wink: ) and C3D with HQ preset. I don't think you need anything else for DVD target. I would go for the Full D-1 encode. 352x480 is very good, but the sharpness difference from 720x480 to 352x480 is like night and day :D -kwag |

Kwag,
What do you think of Peachsmoother? I've found it to be very, very fast. Using it and TemporalCleaner is much quicker than Spacedust + temporalcleaner but with playing with the settings it could be possible that no other filtering be needed. Jim Quote:

I'm using Peach instead of Space now. It's so much faster, and I like the quality much better. It looks much more natural, and the compression is excelent. Look at this sample. which is a full screen movie I'm currently encoding at 528x480 and targeted to one CD: http://www.kvcd.net/test-sea.mpg The script used is this: Code:
LoadPlugin("C:\MovieStacker\MovieStacker\Filters\MPEG2Dec2.dll") -kwag |
Hey Kwag,
Have you done a sample comparison yet between using FaeryDust or PeachSmoother? I'd be interested in knowing which gives the best quality (I realize this can change depending on the source also, but I mean generally speaking). Personally, I've always used FaeryDust because I didn't like the resulting quality of SpaceDust as much, even though it was quicker. I'm mainly wondering if the results with PeachSmoother would be as good (or better!?!) than FaeryDust. If PeachSmoother is better than SpaceDust, and equal to or better than FaeryDust, then I just might have a new favorite filter! FaeryDust takes FOREEEEEEEVER! (although it's certainly been worth using it so far, and I hope Steady keeps working on it :) ). Of course, I'll do some sample tests of my own...but I'm just curious of your opinion (or anyone else's who has compared these filters). Thanks. :) -d&c |

dazed&confused - see http://forum.doom9.org/showthread.ph...threadid=44335
There is a comparison between some of the best noise filters there. I find Faerydust and Pixiedust to be the best, but - and its a big BUT - its too slow. Peach looks great on my Tv captures with strong settings - havn't tried with DVD's yet. However, Peach is faster than Spacedust and does better filtering. Its not far of FaeryDust in terms of quality but it definately does leave the odd stray pixel. Combining it with TemporalCleaner tends to do the trick though! Kwag - For tv caps i've been using - ConvertToYUY2() LegalClip() Crop(16,64,-16,-64) PeachSmoother(NoiseReduction=50,Stability=20,Spati al=120) TemporalCleaner() DctFilter(1,1,1,1,1,.5,.5,0) Crop(4,0,-4,-0) LegalClip() I've really upped the settings for Peachsmoother - probably over did it on this example but the source was quite noisy. It did just as good a job as pixiedust. I didn't set the params for noise etc because the docs say peach does a good enough job on its own. I'd like to get to the point where i can find some params for a filter like peach and i don't have to chain filters. Jim Quote:

Hi there,
I would like to verify the proper order of the script, should MergeChroma(blur(1.5)) be placed before or after the resizing line? Will the speed be affected? |

I did a good deal of testing today (repeatedly viewing test clips in 1x and 1/8x speed on a 30" 4:3 ntsc TV) between Faery, Space and PeachSmoother (using same settings as the doom9 thread author), and personally I think I agree with jamesp for now that FaeryDust is still the best of the best for avisynth2.07 (if time is not an issue!). But that's just my $0.02, which certainly isn't as valuable (or knowledgeable) as many peoples' $0.02 around here. :oops: :wink: While PeachSmoother did look very similar to Faery in detail/sharpness to me, there was a very annoying flaw that occurred when one particular actor nodded his head up and down several times. The actor was dark-skinned with very short-shaven black hair. While he nodded, it was as if a large portion of the side of his head stayed in a fixed position while the rest of his head was moving. It was quite noticeable. Using c3dLQ rather than Tempcleaner helped hide it some, but it was still noticeable. This happened again in another scene with the same actor when he turned his head to talk to someone. Since the flaw was only noticeable with this one actor, I have a feeling that perhaps those specific Peach settings were just a poor match for his particular flesh-tone. With the right settings-tweaks, Peach still might prove to be a good choice for me. But I don't know a lot about "tweaking" parameters, especially when there's a lot of them...plus I'm lazy :lol: . I like to use defaults() whenever possible, and both Faery() and Space() looked better to me on this particular video clip. So I'm sticking with Faery(for overnight encodes) and Space or Space+LanczosResize(for speed) for the time being until someone smarter than me figures out an all-around good default setting for Peach. Or until I'm feeling a bit less lazy (but that might be awhile!). ;-) In hindsight, I probably should have tried Peach's default() parameters also. :roll: :lol: D'oh!! I need a :drink: :!: I wasn't going to post my test results, but figured someone might find them of minor interest. As you can see below, there wasn't much of a speed gain by using Peach instead of Space on this particular movie-trailer. I suppose different sources will vary though, as always. -d&c Code:

I have never seen this with spacedust, pixiedust or fairydust. I'm going find that same scene and encode it with different parameters in Peach. If it still shows, then there's a nasty bug in peach :!: :!: :!: -kwag |
PeachSmoother is flawed!
As the subject says. Here's the scene I mentioned above: http://www.kvcd.net/peach.mpg
Look carefully at her hair :lol: There's an obvious bug in vertical movement in peach. Now here's the same scene with spacedust: http://www.kvcd.net/space.mpg I even tried peachsmoother() without parameters. Same effect 8O I'm going back to spacedust :idea: :!: Thanks so much dazed&confused for pointing this out :D -kwag |
Re: PeachSmoother is flawed!
Heh guys, before throwing your Peach out because you think its gone mouldy :D - it could be a problem with your avisynth script. The docs to Peach state that Peach should be used as early in your script as possible and before any other filtering. In your scripts i've noticed its being called after MergeChorma + MergeLuma - this could be the problem - just a thought anyway! In all my tests i've used Peach first and i've not noticed the problem (although that doesn't mean it exists!)

Hi Jim,
The problem is present even if you use PeachSmother only in your script. I tried stripping out every other filter, and just using peach, and the effect is still present. It's definitely a problem with the filter :!: -kwag |
Oh well :(
The hunt for the best filter continues! :lol: With those two clips, Peachsmoother definately looked the most natural, if you ignore the dancing hair :!: I find spacedust doesn't look that great. FaeryDust is great on its own with no other filters but is slow. Fluxsmooth makes eveything a little blurry. Ive never tried convolution3D - i'll try that one next. Have you contacted the author of peach about the problem? if not i'll contact him through doom9 forums. Jim Quote:

Hi dazed&confused,
Here's the sample you sent me, so everyone can see the same effect on your clip: http://www.kvcd.net/PeachFlaw-head-nod.m1v -kwag |
Kwag,
I've just tried Convolution3d (Preset=Movielq). The results look excellent and compressablitly is very good. Looking at the results it looks far more natural than SpaceDust or Peach. Have you tried this filter yet? Jim Quote:

I'll try it later today :) -kwag |
I'll post later tonight - i'm doing a comparison of most of the major filters we all use, it will chart compressability and quality to my eye!

Hi Jim,
Remember that using C3D, the final file size will be larger than using SpaceDust :!: -kwag |
I got a reply from the guy who wrote peachsmoother. He writes:
You’re seeing the standard behavior where the Peach is really, really sure that there’s no motion. Usually that means the noise estimate is off — Take a look at the docs on the “dot” option and on the “I’m seeing lots of blurring...” question. __________________ 9:) Lindsey Dubb Looks like thats just the way peachsmoother works.

so if these settings were used and people were getting stationary or slow moving hair...
PeachSmoother(NoiseReduction=45,Stability=15,Spati al=70,NoiseLevel=4.8,Baseline=3.2) To fix the problem... Could you just lower the baseline or have the baseline set to zero? |

When oh when is Steady gonna release a new and improved version of Dust? We're all dying for an update :!: :wink: -d&c |
:roll:
:idea: ..... talking about busy guys and good filters..... :? where is Sansgrip :?: :?: :?: :( and please, what filters you all are using now? :? :?: |

My current script of choice looks like this: Code:
Mpeg2Source("F:\movie.d2v") -d&c |
friend dazed&confused :wink:
i will do a sample with your script . :!: thank you! :D someone more? ps: dazed&confused is one music of the first "ledzep" album and in "the song remains the same" movie! very 8) music. :mrgreen: |
Sadly, it looks like very few people are developing their filters anymore. Vlad (who wrote convolution3d and ported TemporalCleaner) says he has no time anymore. Lindsay Dubb has no time to develop peach and steady hasn't been seem for ages so there is no news on Dust. And sadly, Sansgrip looks like he's even too busy to pop in here from time to time, let alone develop any filters. I suppose that real life always takes over in the end, and people have to get back to their lives and families.......

Hi there,
It's been quite a while. Does anyone has any suggestions for KDVD's filters, I am interested in latest script for clean DVD source. I have been using LegalClip + Mergechroma(blur(1.5)) + SpaceDust() as suggested by Kwag long time ago. Any suggestions please! |
Hi syk2c11,
Check the current script section :wink: -kwag |
Hi Kwag,
Are those latest scripts suitable for KDVD full-D1, I remember you had said that KDVD full-D1 does not required that heavy filtering. Please advise. |
