I have an avi. file with bad quality, 352x288 . I have'nt encode a file with a quality who is this poor... So do you have any suggestions on filters and I should use to make the quality as good as possibe I tried with a script witch I use when making svcd's but the result made me cry I was'nt happy. I used this filters.

ConvertToYUY2()
LegalClip()
GripCrop( width= 352, height=288, overscan=1 )
GripSize()
SpaceDust()
TemporalCleaner() <-- (OLD)
GripBorders()
LegalClip()

So please, can you give me some advices on how to make this go better next try?

It's simple. Crap in = Crap out.
there's no filter in the world that could change this...
however use bicubic resize if you upsample a movie's resolution.
Also what do you mean with very bad quality? is it just the resolution, that make the movie bad quality? is there a lot of noise? blockiness on high action scenes? or everything?

A script like that is far too soft for any type of poor quality avi. You're probably not going to get very good results. Very heavy smoothing is all you can try...try a script like this:

Code:
ConvertToYUY2()
LegalClip()
GripCrop(width= 352, height=288, overscan=1)
GripSize()
mergechroma(blur(1.58))
mergeluma(blur(0.08))
GoldDust()
Convolution3D(preset="vhsBQ")
GripBorders()
DctFilter(1,1,1,1,1,.5,.5,0)
LegalClip()
The end result will probably be far too smooth though...

@Jellygoose, Thanks for answering so quickly

Yes it is a lot of blockiness, but one thing I dont understand...what is "noise" some audio stuff Should I add Blockbuster to the script PyRoMaNiA showed me or will Convolution3D(preset="vhsBQ") take care of the blocks?

@PyRoMaNiA, Thank you to for answering quickly

About these filters: mergechroma(blur(1.5), mergeluma(blur(0.0), GoldDust() and DctFilter(1,1,1,1,1,.5,.5,0) is there a readme for them cause I havent heard about them ( have heard about GoldDust() but actually I dont know what it makes )

And if there is NO readme at all, please can you tell me about them, spelcially mergechroma(blur(1.5), mergeluma(blur(0.0) and DctFilter(1,1,1,1,1,.5,.5,0)

//Thanks a LOT

Hi Wolfi!

First read here about noise and MPEG Artifacts. Pictures are there, so you can compare these to your clip.

http://www.doc.ic.ac.uk/~nd/surprise...ort.html#probs

mergechroma and mergeluma are implemented in Avisynth 2.08. DcT Filter and GoldDust (which is part of DustV5), you can download in the Download Thread here in the KVCD Templates Forum. you can read the readme's of the different filters to determine its purpose.

If you still have questions after that, feel free to ask!

BtW: There's no way you can rid of heavy blockiness in the source material sorry. you can try to smooth them out a little and make them less apperant, but you'll probably not be satisfied with the results.

THANKS Jellygoose

But, the blockiness is in the m1v file NOT in the source I'm using AviSynth 2.07 should I update or does'nt it matter ?

Update to 2.08.
Try out the filters, and tell me what you think.

HHMM I tried the script using AviSynth 2.08 but when I played it in WMP

Unrecognized exception!
(C:\Documents and Settings\Lars\Skrivbord\Tobias\Filmer\movie.avs, line 19)

I used this script as you told me to do:

LoadPlugin("C:\Documents and Settings\Lars\Skrivbord\Tobias\Program\Blandat\Fit CD\MPEG2DEC.dll")
LoadPlugin("C:\Documents and Settings\Lars\Skrivbord\Tobias\Program\Blandat\Fit CD\GripFit_preview.dll")
LoadPlugin("C:\Documents and Settings\Lars\Skrivbord\Tobias\Program\Blandat\Fit CD\LegalClip.dll")
LoadPlugin("C:\Documents and Settings\Lars\Skrivbord\Tobias\Program\Blandat\Fit CD\Sampler.dll")
LoadPlugin("C:\Documents and Settings\Lars\Skrivbord\Tobias\Program\Blandat\Fit CD\DustV5.dll")
LoadPlugin("C:\Documents and Settings\Lars\Skrivbord\Tobias\Program\Blandat\Fit CD\TemporalCleanerOld.dll")
LoadPlugin("C:\Documents and Settings\Lars\Skrivbord\Tobias\Program\Blandat\Fit CD\Convolution3D.dll")
LoadPlugin("C:\Documents and Settings\Lars\Skrivbord\Tobias\Program\Blandat\Fit CD\DctFilter_YUY2.dll")

AviSource("C:\Documents and Settings\Lars\Skrivbord\Tobias\Filmer\Mr Deeds\movie.AVI")

ConvertToYUY2()
LegalClip()
GripCrop(width= 352, height=288, overscan=1)
GripSize()
mergechroma(blur(1.5)
mergeluma(blur(0.0)
GoldDust()
Convolution3D(preset="vhsBQ")
GripBorders()
DctFilter(1,1,1,1,1,.5,.5,0)
LegalClip()
#Sampler(length=24)
## MPEG size = ((Total frames/MovieTimeInMinutes)/24) * MPEG sample file size ##

Whats wrong with my Convolution3D line, I cant see anything

Your mergeluma line is 0.0, try to change that to 0.5!

If you guys don't want the emoticons to show, always use a space between a number and a closing parenthesis. For example, this will display an emoticon:
(0.0 but I typed 0.08
But this will show correctly:
( 0.08 )

Try changing this line: Convolution3D(preset="vhsBQ") to read: Convolution3D(preset="movieLQ") and see if the error dissapears.

Look at this

Convolution3d (preset="vhsBQ") // VHS capture Bad Quality (???)
is an alias for Convolution3D (0, 32, 128, 16, 64, 10, 0)

I changed the line Convolution3d(preset="vhsBQ") to Convolution3D (0, 32, 128, 16, 64, 10, 0) Will this line do the same jobb as Convolution3d(preset="vhsBQ")

I found this readme http://hellninjacommando.com/con3d/readme.html

That's exactly what the "presets" do.

So you mean that I can use Convolution3D (0, 32, 128, 16, 64, 10, 0) . You can just write it in two differet ways

So what do you think works best
Convolution3D(preset="movieLQ") or
Convolution3D(0, 32, 128, 16, 64, 10, 0)

If your source is really bad quality go for Convolution3D(0, 32, 128, 16, 64, 10, 0), if it turns out too smooth you could try movieLQ instead...
