Avisynth Script

[danube100]

Hi Guys,
This is my first post on Doom9 so I don't know whether this is the correct section to post this or not.
I am new to ripping and after following some guides on how to rip using megui I have made the following AVS script but know what does it mean and wanted to know that how can i improve my scripts in future so that I can get a better print.

The AVS Script
DGDecode_mpeg2source("C:\Documents and Settings\Arjun\My Documents\DVDFab\Log\Sample.d2v", info=3)
ColorMatrix(hints=true, interlaced=true, threads=0)
tfm(order=1).tdecimate()
crop( 10, 58, -8, -62)

Lanczos4Resize(720,304) # Lanczos4 (Sharp)
#denoise

how can i improve my scripts in future There's no recipe that applies to all video sources. You must go on a case-by-case basis.

Thanx neuron but wanted to understand the case by case basis as i know that every source is different and it requires different filters.
I just wanted to know that how do i know whcihc filter i have ti use for which source.

This is something you'll learn with time. You'll find yourself using heavy duty denoisers (FFT3DFilter, MCTemporalDenoise, mc_spuds) when you have to deal with bad noise, or filters like MCBob or TempGaussMC when dealing with interlaced video.

You'll find with time, as you work on more and more videos, you'll discover what to use when and where. Just ask questions in the avisynth forum when you get a source you're having trouble with, and we'll guide you along and you can learn how to deal with the issues that show up.

Thanx for helping me out. Okay i understand that i will learn with time but my basic doubt is can sumone explain me the script on the top bcoz i should know the meaning of what i am doing or what megui is creating for me.

Why don't you start with the AVISynth wiki and look up the functions, it will explain in depth what they do.

Well which parts of the script don't you understand?

line 1 is the source that avisynth uses as it's input (http://avisynth.org/mediawiki/Internal_filters#Media_file_filters)
Description of ColorMatrix (http://avisynth.org/mediawiki/External_filters#Chroma_correction)
Description of tfm (http://avisynth.org.ru/docs/english/externalfilters/tivtc_tfm.htm) - avisynth.org entry, under TIVTC (http://avisynth.org/mediawiki/External_filters#IVTC_.26_Decimation)
I would think Crop (http://avisynth.org/mediawiki/Crop) is pretty self explanitry
And Lanczos4Resize is a resize filter, specifficly Lanczos4 method, there are lots of different types of resize filters description of resize filters (http://avisynth.org/mediawiki/BicubicResize)

As you can see the majority of information on AVISynth is kept in the wiki.... you just have to do a little research.

The interwebs is a big place, theres allot of information there, you just need to find it, Google is your friend.
