SVCD Quality

[CrazyPortuguese]

I've tryed to do some encodes and I usualy got some hollows arround the subtitles and the images, and some time I got some pixels in fast frames but now I'm using 2 90 minuts cd's overburn to 947MB and those problems completly disappeard but now I've noticed that the colors on dark images are not smooth, they aren't even I can see some parts where I see squares, this only happens in dark frames :(
This never hapned to me at least in this magnitude, could this have to do with reducizing the number of passages CCE does, from 5 to 4 ? I've also changed the resize methode from Bicubic Resize to Bilinear. Could it be because of this change ?
Is there any thing I can do to solve this ? Image quality priority, Field Order and etc.

Sorry for not beeing able to explain my problem that well.

Try raising the min bitrate. Dark Scenes = Low bitrate. The lower the bitrate the worse it looks.

Don't thank me before you've tried it. It might not be as good as you want it.

Min 600 sounds good to you ?

here is what my avisynth script looks like

LoadPlugin("C:\PROGRA~1\DVD2SVCD\MPEG2Dec\mpeg2dec.dll")
LoadPlugin("C:\PROGRA~1\DVD2SVCD\avisynth\tweak.dll")
mpeg2source("D:\dvd\DVD2AV~1.D2V")
Tweak(bright=12)
sharpen(.4)
BicubicResize(480,480,0.00,0.60)

If i use sharpen(.4) with my settings below i get awsome results.

I use a max 2530 Min of 755 Min Avg. unchecked Max Average 2230 with bicubic of B value 0.00 C value 0.60 and also i use 5 pass vbr with anti noise 12 and image quality priority set at 17

Sorry for the dumm question but how do I change my avisynth script to look like that

:) Newbie question I know :) But Image Quality is really important :)

It is easy to edit your Avisynth Script File, just go in to dvd2svcd and click on the Frameserver Tab then at the bottom left you'll see these options

No Editing

Edit when dvd2avi processing is done

Edit as part of Video encoding

I always select Edit As part of Video encoding. One more thing You have to download Tweak.dll here is the link http://sauron.mordor.net/dgraft/ download that put it in your root directory or somewhere with a path thats about it i think.

I'm sorry for making you loose your time once again but could you please tell me under wich name that file is tweak.dll because I can't find it in that site I went to hosted but didnt find anything there :)
Thanks

Look under the "mine" on the site. It's called Tweak under the AVIsynth filters. There are only 2.
There are other options as well to that filter. In addition to the bright chainsaw135 uses I add cont=1.3. This increases the contrast, but I do it because my DVD player plays a little dark so I make the image brighter.

Basically that is what you can do with Tweak. You play with the things you would on a TV like brightness, contrast, color etc...

Make sure you read the included txt file and if you ever need a quick answer Donald(who is a genius) hangs out in the Avisynth forum.

If you don't think your image is too dark then I wouldn't bother with the filter.
