How can I enhance the Video Quality with XviD?

[sleekychap]

Hi all:

I am trying to get a 2 CD ( 1400 MB ) DVD rip using XviD and Gordian Knot
Basically I am using all applications within Gknot.
So, I am doing a forced film if the source is hybrid and the film % is greater or 95%. other wise.......'Honor Pulldown flags'
next I am following the recommended resolution settings...0.27 pixels /frame for a 2 CD rip.

But when it comes to the scripting part...I am lost there in all kinds of filters that may be used....to improve the quality of the video ( basically to get good sharp picture) I used some filters like asharp(), msharpen() and unfilter()...but all of them are doing just sharpening...the video looks good at 100% but when I see that full screen or 200% the image becomes really fuzzy.....


here is the script:

LeakKernelDeInt(order=1,sharp=true)

# CROPPING
crop(8,58,704,368)

# RESIZING
Lanczos4Resize(704,304)
#aSharp()
#MSharpen(threshold=8)
Unfilter(1,1)
DeSpot()
# DENOISING: choose one combination (or none)
mergechroma(blur(1.3))
Tweak(bright=1)

#VagueDenoiser()
#VagueDenoiser(threshold=0.8,method=1,nsteps=6,chromaT=0.8)

So among all the filters....can anyone suggest me good filters to get a good overall picture at the end? not just sharpening or image stabilization???

Thanks.......

try AutoGK

Hello and welcome to the forum-

Was this example you posted a movie? Was it Force Filmed? If so, I'm not sure why you're deinterlacing it with LeakKernelDeint. If it's from a good clean source, you shouldn't need to filter at all. Filters may improve the quality of a bad DVD. If it's from a good DVD, spatial and temporal filters usually do more harm than good. In my opinion.

Thank you for the reply...
This was for a bad DVD actually. The actual source was at 30 fps and I used forced film it in DGIndex and then tried to deinterlace it. The usual quality I get from autogk for the same thing is not satisfactory. Can you suggest a set of operations ( Do's and Dont's) to perform on a clean DVD source (new) and that with an old DVD ( bad source) ...

Help much appreciated.... :thanks:

How do I use Limitedsharpen() after sharpening??? I searched the forum but got no tangible filter as such...where do I get that plugin/filter????

LimitedSharpen is not plugin/filter. It is avisynth script acting as function. It uses many filters/plugins. You can find it and read about here:

you have to use it not after sharpening, but instead.

...I used forced film it in DGIndex and then tried to deinterlace it...That's a flawed process. See www.doom9.org/ivtc-tut.htm for more assistance with interlaced or Telecined content. The tutorial is a little out-of-date -- e.g.: DVD2AVI has been replaced by DGIndex -- but the process of examining content hasn't altered.

Thank you guys for the initial push....I will try to rectify what I was doing wrong and will surely get back here with " fingers crossed" good results
:thanks:
