Not good quality, what change?

[Kermit25]

Hello.
First I have tell You, my english is quite good, but I thing You understand me. Second, this is my first topic in this forum, and I don`t know, if this is good pleace. If no, pleas change, but not delete. I need help; soo.

I have a movies in mpeg files (mpv, and mpa). I tray to convert to avi files, but quality is not good. Could You help me? I create avs file:
LoadPlugin("C:\PROGRA~1\GORDIA~1\DGMPGDec\DGDecode.dll")
LoadPlugin("C:\PROGRA~1\GORDIA~1\AviSynthPlugins\UnDot.dll")
mpeg2source("E:\Ferguson\Syrenka04.d2v")
trim(1357,23521)
crop(10,2,-10,-4)
LanczosResize(640,480)
Undot()

What can I change in this script (what add, delete, change,...) to receive better quality avi file?

This is sample of source (without audio):

I waithing for Your advice.

I haven't downloaded your sample yet, but can you clarify specifically what you mean by "not good quality"? e.g. blocking, noise, color etc..?

Is it a problem with the source?

Is it a problem with encoding? If so what encoder/settings did you use? Using a higher bitrate will usually improve quality (make it less lossy)


EDIT: ok, I see there are field repeats, and blends. You can try one of the restore functions like srestore

I forgot.... The most important is noise and interlaced. When I tray delete interlaced, I got worst that was (source). I tray DeBob and Kernel.
Quality source is wery good. When I watch (on TV or PC), everything is OK, but when I watching avi - "Oo my God"

To encoded I use XviD 1.2.1 (2-pass)

Bitrate is not a problem (I thing), becouse even if I use higher for example 1800 (normal I tray use 900-1200), I don`t see Betterment.

Edit...

Could You write script (how use restore functions)? Please. I be lerning from You :)

[poisondeathray]

I'm not an expert, I'm learning too...

Most of your noise is distributed around edges, so here is a suggestions. You can tweak it to your tastes (e.g. if you want it more clean, vs more detail, etc..). The biggest problem I see is the low quality source, edge noise, and field blends. Srestore can help, but there are still some blends. I'm sure the other doom9 experts might have better suggestions


mpeg2source("syrenka_sample.d2v")
yadifmod(order=1, field=-1, mode=1, edeint=nnedi2(field=3))
srestore(frate=23.976)
Dehalo_alpha(darkstr=0.5,brightstr=0.5,rx=3,ry=3)
edgecleaner(strength=30)
awarpsharp(depth=12)
Deen(mode="a3d")
Toon(strength=0.5)
LSFMod(strength=50)


Cheers

OK/ THX for Your help. I tray use You sugestions.
BTW. I must download some plugins to AVS?

[poisondeathray]

Yes, you're going to have to search for them :( I don't know of any 1 place that has all the collection of filters

[Kermit25]

Maeby I find, but can You write name of this plugin?

[poisondeathray]

They are all written above: yadifmod, srestore, nnedi2, dehalo_alpha, edgecleaner, deen, toon, lsfmod

If the .dll's (some are .avsi's) are placed in the avisynth/plugins folder they are autoloading, otherwise you have to use LoadPlugin() to manually load them

Yes, and I know how use "google" :) This is no problem find the plugins, problem is - how, and what plugin use, to better quality :helpful:

It's called experimenting. (aka. doing it on your own and finding out. They always differ from source to source and use to user.)

I know, but I don`t know all plugins (good plugins) who reduce noise. I know few. You know, more! And You can use them. If You show my few, I can experimenting, change few options, use/not use plugin. But I need someone (like poisondeathray), who show me good plugins, and how tu use them. Please.

Nightshiver is right - the only way to learn and understand what the filters are doing is to experiment with each one. A good utility to use is AvsP, you can change the script and see the preview. Every source is different, everyone's individual tastes are different, so you have to do this ultimately yourself

For example, I just learned some good stuff the other day from this thread. I added a warpsharp in the script I suggested above to clean the lines up a bit

In addition to the warpenterprises list, here are some more filters listed by function
