Aplogies if that wasn't meant for me. BB noise in my divx script is supposed to be removed (= blended in) by the following ATC filter. The combination of these two helps randomise and smooth out flat areas that show many random flashing blocks in divx/xvid sources.
Try adding +175% contrast, +5% brightness to a divx source and looking at eg: background walls. Then add ATC, then BB, then BlindPP and then finally ASharp and observe the differences!

Thanks for that, I caught it on the other thread :) But in this case I'm adding detail adaptive noise not motion adaptive noise :) I'm still experimenting though (aren't we all?)

dirv just wondering how your experimentations were going on this thread! With so much emphasis on the latest optimal script, which is meant for clean DVD sources, I think other blocky divx/xvid sources have been forgotten. I'd love to hear where you are for this. All my divx-->kvcd encodes have a lot of mosquito noise and other crap. I'm sure some of it comes from already having a compressed source but I'd sure love an optimal script with MA filtering meant for these files!

What I think is that too much people forgot the purpose of KVCD is to make private copy or your own DVD.
I don't find we put emphasis on clean sources, we just talk about what we are supposed to talk.
I do not know a lot of people trying to turn into KVCD the divx they did of DVD they own.
Do you ?

I agree 100% with you Phil. However, there are also lots of noisy DVDs around, so a better script for noise reduction would be a good idea in my eyes.
But yes you're right. I don't see the point in making a DivX optimal script either, since you usually don't encode your own DVDs twice.

and i am with you 2 !
how to backup your own dvd with the best quality in
short space and play the result in all pcs or dvd players
that is the central idea of KVCDs

I don't own many DVD's but have a large collection of VHS tapes that I would like to digitize and store on CD. KVCD with the optimal Avisynth 2.08 script works quite well, but I am still eagerly awaiting an optimal MA script for VHS capture sources!

Didn't think about that. We have to find a successor to FaeryDust usable in a MA script. That is something to think about
Note: just to know, did you try the MA script on VHS capture ?

To be honest I haven't tried the MA Script at all, yet.
I recently had to re-configure my entire PC and finally got both versions of Avisynth working with Avisynthswitcher.
I'll try to run the MA Script on a VHS source this weekend.

Are you guys still toying with Blockbuster? Have you tried this:
Blockbuster( method="dither",block_size=3,luma_offset=-2,luma_threshold=30,detail_min=1, detail_max=30 )

Yep. And it's no good. Even SansGrip agreed, as it was only an experimental feature. The picture looks like if you are looking through a screen

Alright then I'm just trying to get rid of these damn blocks on THE RECRUIT at the begining. I'm using the MA Script. They are less noticable on a progressive scan DVD player but I'm not in the market to buy one right now.

Hi Holomatrix,
Try encoding with CQMatic, and encode as CQ_VBR with Blockbuster. That should get rid of the blocks

Ok, so what script would I use then for TMPEG adding blockbuster? plus I can only encode to SVCD mpeg2 because my DVD player does not play KVCD well. Does that change anything?
Thanks

You can use the current script ( http://www.kvcd.net/forum/viewtopic.php?t=3483 ) for AviSynth 2.52, and add your Blockbuster line after this code:
Code:
SwitchThreshold = (Width<=352) ? 4 : (Width<=480) ? 3 : 2
ScriptClip("nf = YDifferenceToNext()"+chr(13)+ "nf >= SwitchThreshold ? \
unfilter( -(fmin(round(nf)*2, 100)), -(fmin(round(nf)*2, 100)) ) : \
TemporalSoften( fmin( round(2/nf), 6), round(1/nf) , round(3/nf) , 1, 1) ")

No, not at all
But as your player can only play MPEG-2, you might also be able to use other resolutions at mpeg-2
Like 528x480(576). Have you tried that , and then mux as SVCD

Ok, thanks, I will try that res but if I do, dosen't that drop the CQ alot? I still want to do one CD encodes. Since you don't recomend Blockbuster(dither) hows this-
16=SwitchThreshold = (Width<=352) ? 4 : (Width<=480) ? 3 : 2
17=ScriptClip("nf = YDifferenceToNext()"+chr(13)+ "nf >= SwitchThreshold ? \
18=unfilter( -(fmin(round(nf)*2, 100)), -(fmin(round(nf)*2, 100)) ) : \
19=TemporalSoften( fmin( round(2/nf), 6), round(1/nf) , round(3/nf) , 1, 1) ")
20=Blockbuster( method="noise", variance=.5, seed=1 )
Thanks
