KVCD: Trouble Converting AVI Movie?

Bald_Guy · #1 02-15-2003, 10:34 AM

Ok after many hours of reading and finally understanding the concept of this avs thing I came to the conclusion I suck at it. Anyway a lot of my movies are xvid. The latest file info is
Width 576x256
length1:15:09
framerate23.976
#offrames108117
xvid-mpeg4
filesize700meg
This is only one of the two disks. The other one is very close in size. I would like a little help in picking what kvcd template for make a very hq 2 disc out of this 2disc. Also how to make the script so I keep the right quality. All of my atempts so far have failed. I would hate to go back to making the 4 disc xvcd's. But if I dont figure this out thats the only other way. Because with 4 disk I can keep the quality. Please any help is very apreciated.

Hi Bald_Guy,

Go for KVCDx3 if your player supports it.

For XviD to KVCD and great quality on 2 CDs, use these filters:

Code:

LoadPlugin("C:\encoding\mpeg2dec.dll") 
LoadPlugin("C:\encoding\GripFit_preview.dll") 
LoadPlugin("C:\encoding\legalclip.dll") 
LoadPlugin("C:\encoding\sampler.dll") 
LoadPlugin("C:\encoding\convolution3d.dll") 
LoadPlugin("C:\encoding\dustv5.dll") 
[ ** Your AVI source line goes here ** ] 
LegalClip() 
GripCrop( width=528, height=480, overscan=2 ) 
GripSize() 
SpaceDust() 
Convolution3D(preset="movieLQ") 
GripBorders() 
LegalClip() 
#Sampler(length=24)

Hi Bald_Guy,

I have done a few of these conversions so maybe I can help.

Ya gotta use avisynth and prediction to get good quality there is no way around it and you will be thankful you did when you see the quality.

I personally use fitcd to generate a bare bones avs script and then build on it depending on the movie I am encoding.

Try to encode at a higher resolution like 528x480 if your player will support it (I have to burn as my mpeg1 as svcd to use this res but it is worth it).

Code:

AviSource("D:\rip\The.Tuxedo.avi" ,false)
LegalClip()
BicubicResize(528,352,0,0.6,0,0,576,320)

GoldDust()

Convolution3D (0, 32, 128, 32, 128, 10, 0)
AddBorders(0,64,0,64)
LegalClip()

#Sampler(length=24)

This is the a script I used recently on a 90 min movie, the quality of the source was not as good as I would have liked so I was pretty agresive with the convolution and dust filters but this enabled me to increase cq and thus increase quality of my encode.

The other tweak I have been using for avi encoding is to play around with the max bitrate. I check my sample with Bitrateviewer if the average bitrate is 900 then I will change the max bitrate in tmpg from 1800 to 1300 and do another sample to check the quality. I have found this gives me the ability to use much higher cq and thus better quality.

I only do this with divx/xvid source as they are already highly compressed and so bitrates dont seem to get as high as when using dvd source.
