Hi people :),


i´ve been using avisynth for some time,
although, i´m still a newbie in the subject.
I wanna know how is called that frenetic noise in colour in
this video and how i could fix it.
In fact, i dont know if the problem is in the colour or if it´s coincidence it´s pronounced in some areas by the colour.

I would like some help in how to improve this video quality.

I´m getting very good results in other videos, but this one is been a challenge for me.

Any suggestions?

Try ccd_sse2.v.1.6.MT.25.04.2009
Camcorder Color Denoise 1.4 SS2

It can run from VirtualDub and Avisynth.

This is how you run in from AVISynth

LoadVirtualDubPlugin ("C:\Program Files (x86)\AviSynth 2.5\plugins\ccd_sse2.vdf", "CamCD",1)
AVISource("C:\clip.avi")
ConvertToRGB32().CamCD(10).ConvertToYV12() # for Progressive

Hi,

thanks for the tip!
Appearently it works, but virtualdub was showing error on the command line.

I researched and found this:

ConvertToRGB32().CamCD(30,2).converttoyv12()

Well, i cant find any documentation about this plugin, but the image quality is better.

If anyone can help with a link for documentation or can explain the parameters for the plugin, it would be nice!

5 sec googling for 'Avisynth camcd', downloading, 2min figuring out the needed character set, 5 sec translate through google translate,.... -> work on you google-fu ;)

Camcorder color denoise 1.6 MT

The filter is designed to remove from the interlaced color noise matrix cameras. The default setting is optimized for camera canon md160.

Applying a filter in AviSynth:

LoadVirtualDubPlugin ("c: \ Program Files \ VirtualDub \ plugins \ ccd.vdf", "ccd", 0)
ConvertToRGB32 (interlaced = true)
ccd (30,1)

where:
30 - level of treatment, 0-100 (over 100 works, but undocumented)
1 - includes multithreading, 0 - off

The number of threads is determined automatically depending on the type of processor, up to 4.

:D

I should practice more my google-fu, master!

So, what it means when they use CCD(30,2) ?
Is it forcing to use 2 threads?

My script now is:

MPEG2Source("D:\funilaria.d2v", cpu=6)

QTGMC( Preset="Placebo" )
SelectEven()
ConvertToRGB32().CamCD(30,1).ConvertToYV12()
awarpsharp2(depth=8)

I dont know if i am doing anything stupid, but quality is good for me and the filesize dropped by half with use of CamCD. Any suggestions about the script?

Thanks!
