Ahh!, well, I'm having a little red wine today. Just opened a bottle of Spanish wine of "Torre Oria" (1994) :mrgreen:
So I'll be a little :Drunk: in a while :lol:

I love this forum. Not only for the talented people that provide their knowledge but for the fact everybody has a little fun. I get plently of laughs just reading some your guys posts.

Yeah, I just knew this thread was going to take us somewhere :lol:. These filters really make a huge difference. Anyone encoding at 352x240(288) with all these filters added up, can actually encode with CQ=100 and get a ~120 minute movie on one CD 8O, and even at CQ=100, sampler size is still below wanted size (on most movies) :mrgreen:

Guys I just hate this time difference! Everybody is having a beer while I'm sleeping... :?
Someday we just have to meet at a special time and just get drunk online and chat... then we copy-paste the whole session and post it in the forum somewhere :lol: .

As for the "Maniac Filtering"... I really like the clip you posted. But I don't know if this is maybe a little too much filtering... Well I think the results speak for themselves, but since I haven't seen the DVD I can't compare... still MergeChroma and MergeLuma just have been deported to my standardscript... :lol:

Kwag,

As long as you are going for "Maniac" filtering...

try putting your NoMo settings to

NoMoSmooth(30,2,6,2,6)

so it will be more aggressive to motion...

Also did you try

DctFilter(1,1,1,1,1,.5,.5,0) before spacedust() in your script?

some movies the dctfilter works good on and others very little...

WOW - KWAG Strikes again! My results using a 1 minute analogue tv capture using KDVD:

No Filtering at all : 32mb
PixieDust + Temporal Cleaner : 23 mb
Pixie Dust + Temporal Cleaner + DCT Filter - 22mb
Pixie Dust + Temporal Cleaner + Merge Chorma + Merge Luma - 17.5mb !!!!! :D

Can't see a lot of difference on my pc, although the one with the 2 merge statements seems a little softer, its still sharper than using fluxsmooth and temporalsmoother. Will try a whole film and see if the wife notices a difference!

jamesp,

Instead of Pixiedust...
try

spacedust()
NoMoSmooth(30,2,6,2,6)

same results or better in less time...

I already did, but I used other values on the script :D. I also used Lanczos and dropped BLockbuster(sharpen) and a couple of small adjustments. Here's the final script I used last night to encode the complete S1M0NE movie:

Code:

LoadPlugin("C:\encoding\mpeg2dec.dll")

LoadPlugin("C:\encoding\GripFit_preview.dll") 

LoadPlugin("C:\encoding\blockbuster.dll") 

LoadPlugin("C:\encoding\legalclip.dll") 

LoadPlugin("C:\encoding\sampler.dll") 

LoadPlugin("C:\encoding\dustv5.dll") 

LoadPlugin("C:\encoding\temporalcleanerold.dll")

LoadPlugin("C:\encoding\nomosmooth.dll")

LoadPlugin("C:\encoding\fluxsmooth.dll")

LoadPlugin("C:\encoding\convolution3d")



Mpeg2Source("K:\S1M0NE_WS\VIDEO_TS\simone.d2v")

LegalClip() 

mergechroma(blur(1.58)) 

mergeluma(blur(0.6)) 

GripCrop( width=528, height=480, overscan=2 ) 

GripSize(resizer="lanczosresize") 

SpaceDust()

FluxSmooth(7,7)

NoMoSmooth(40,1,6,1,3,false)

Convolution3d(preset="movieHQ")

GripBorders() 

LegalClip() 

#Sampler(length=24)

Yes I did, but there's was no significant difference in size or quality when used with all the filters above.
Here's what I got with these settings and a CQ value of 71: http://www.kvcd.net/s1m0ne-final.mpg

Remember, this script is just a test. Do not pass go. Do not collect $200 dollars :mrgreen:

What about trying the merge* filters after resize?

Thanks Jellygoose!

I too hate this time difference, it all happens while I am sleeping.

Maybe a full movie on one floppy is dreaming :) but how about on one of the 200mb mini disks this could have ramifactions for the pocket pc encodes 8)

@all: If you use DCTFilter, it should be used as the last filtering item in your script. LegalClip/Limiter and Sampler should be after it, of course, but other than that keep it as the last item. The author, Tom Barry, suggested this himself. The filter zeroes some DCT coefficients and the zeros are the ones that increase compression IIRC.

Tom has also released a new version of the filter which includes diagonal filtering. I posted the link earlier in this thread, check it out if you're interested.

kwag	02-24-2003 08:20 AM

Thanks for that tip Boulder :!:
I'll try that later this afternoon. I had the DCTFilter on top :oops:
So that's probably why I didn't get the effect of more compression :roll: .

Hi boulder,

Ok I tried DCTFIlter after all filters and before the last GripBorders(), but I guess all filters above are already doing a superb job, and the difference was only 102KB smaller on a full sampler run. There is no visual difference at all with or without DCTFilter. Here's the script I tried:

Code:

LoadPlugin("C:\encoding\mpeg2dec.dll")

LoadPlugin("C:\encoding\GripFit_preview.dll") 

LoadPlugin("C:\encoding\blockbuster.dll") 

LoadPlugin("C:\encoding\legalclip.dll") 

LoadPlugin("C:\encoding\sampler.dll") 

LoadPlugin("C:\encoding\dustv5.dll") 

LoadPlugin("C:\encoding\temporalcleanerold.dll")

LoadPlugin("C:\encoding\nomosmooth.dll")

LoadPlugin("C:\encoding\fluxsmooth.dll")

LoadPlugin("C:\encoding\convolution3d")

LoadPlugin("C:\encoding\dctfilter_YUY2")



Mpeg2Source("K:\S1M0NE_WS\VIDEO_TS\simone.d2v")

LegalClip() 

mergechroma(blur(1.58)) 

mergeluma(blur(0.6)) 

GripCrop( width=528, height=480, overscan=2 ) 

GripSize(resizer="lanczosresize") 

SpaceDust()

FluxSmooth(7,7)

NoMoSmooth(40,1,6,1,3,false)

Convolution3d(preset="movieHQ")

DctFilter(1,1,1,1,1,1,.5,0)

GripBorders() 

LegalClip() 

Sampler(length=24)

Hi kwag!

On my sample-run of "51st State" the DCT-Filter saved me 563kb compared to the script only with MergeChroma and MergeLuma... It's not a lot but maybe a couple of MBs in the complete movie... I think it depends on the source... since it's a quite fast filter I'll leave it in my standardscript...

Hi all. I've been running a few tests. Does anyone else think using both the merge statements actually makes the image look too blurry?

You can drop this line: mergeluma(blur(0.6)) and it will look sharper, but your file size will increase. Or you can lower the blur value to increase sharpness.
Viewed on regular TV's, it looks about the same with or without the filters. On a HDTV, it clearly looks much softer. As I said above on a previous post, the script is only for test purpose :wink:

And testing is Fun :D

Actually, if i drop the Mergeluma line i hardly get any extra compression at all. I'm going to experiment with reducing the value. Any ideas how this filter actually works? Does the video actually get blurred or does it merge information from the blurred video into the proper video. Could we pass another filter into it, like spacedust or temporal cleaner? :?

Hi Jim,

Well, you already have NoMo and SpaceDust in there, so I don't think there is need to add another temporal or spatial filter :roll:
