cnr2 correct-AVS lines used, but can't get it to work

[20/20]

I'm realy getting affraid to ask this. But now I can't get cnr2.dll to work.
(chroomanoisereduction)

The plugin is in the plugins-folder.

LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\cnr2.dll")
LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\fft3dfilter.dll")
AVISource("C:\WRITE TO CD\Untitled_0009.avi")
bob
selecteven
BicubicResize(528,297)
Crop (8,4,-8,-5)
Tweak(Sat=1.0,cont=1.0,coring=false)
MergeChroma(last)
FFt3dfilter(Plane=3, Sigma=8, Degrid=3)
cnr2()

maybe I got something messed up. Avisynth org is down. I can;t get any info on the correct usage of cnr2.

I love avsedit. Not only is it a nice little editing tool for scripts, but it has a great help file that contains most of the help docs from the avisynth site, and discussions on most of the better external filters as well, including CNR2.

When you say it isn't working, can you be more precise ? Is it crashing ? Is there no visible effect ?

If you load the script into virtualdub, what happens ?

Anyway, from the avsedit help file

Add the following lines in your avisynth script :
LoadPlugin("Cnr2.dll")
# example
Cnr2() # for TV/VHS caps
Cnr2("xxx", 4, 5, 255) # my suggestion to remove rainbows.
Syntax :

Cnr2 (clip, mode="oxx", scdthr=8, ln=35, lm=192, un=47), um=255, vn=47, vm=255, log=false)

mode :

mode of each components, "YUV"
two modes are possible : wide ('o') and narrow ('x')
narrow mode is more sensible to variations, and less effective

scdthr :

scenechange detection threshold.
lower it to make scd more sensible.
if a scenechange is detected, cnr2 will
reset the filtering for the new scene

ln,lm,un,um,vn,vm : 0 to 255

the n values are the movement sensibility :
higher values will denoise more, but could produce ghosting artifacts
the m values are the maximum effectiveness of the denoiser :
lower them to reduce the denoising effect.

I keep getting "There is no function named "cnr2.dll"
or something.
And yes I visited the partly-working avisynt.org FAQ.
All they say about this is that I have to make sure I do not
have any duplicate avisynths on my HD or so.
I checked and I don't

It's the "or something" that concerns me. If you can't make sure you give us the exact error message, how can you expect us to give you serious help ?

The best I can offer at this point is that you again verify you have cnr2.dll in your avisynth plugins folder, and that this folder is definitely the one in the loadplugin statement in your script.

If it is, then perhaps you need to download a new copy.

error: There is no function named "cnr2"

checked, it's there, I always use copy-past to ensure it's correct.
got 2 more plugins in my script that are in the same plugins folder, and they function.

cannot seem to get another copy of that .dll anywhere.. As if not supported anymore.

Hi-

Evidently there's a broken version of CNR2 floating around, and you must have stumbled across it:

Here's the fixed version:
