Request: someone please fix CNR2 - Page 2

so that's not too bad I believe because halving the values just works fine for YUY2.. but one has to take care of input colorspace when using the filter, so I suggest if you plan to update the release someday, simply leave a note in the DOC (I am not a programmer so I won't easily be able to look for the "error" in the code which seems to be a forgotten multiplicator or divisor)

Good work, just to repeat once more

you've helped me very much with your 2.6.1 !!!

To be quite honest I'm not sure if it is an error. Even the source included with the dll currently on marc fd's site matches the output from the source wilbert linked to before and the output from 2.6.1 and does not match the output from the included dll itself. Also, the way YUY2 is handled in those sources seems to be correct to me. I guess I could simply change the defaults for YUY2, but I don't really see a reason too as users should be tweaking the settings for every source anyways

I just checked the "original" CNR 1.1 for VDub (Gilles Mouchard), the defaults read 16, 21, 21 for the n-values - higher values start the filter to produce ghosts. Seems the defaults for cnr2 v2.4 have been chosen wrong... after seeing this (I did not check before I must admit) I also believe it's correct the way you "finalized" it. Shouldn't have compared it to the 2.4

Video processing can sometimes be rather confusing, but it's very much fun, too (I just started one year ago as a complete know-nothing...)

...and of course you're right, filters should be tweaked for every material which I usually do - cnr(2) was my only favourite which clearly showed that the defaults are just fine for anything I tested it with (but it's NEVER the only filter I use - it's for prefiltering VHS-Caps only!)

What's the latest release of this plug in?
According to Trtical home page:
http://web.missouri.edu/~kes25c/
It's 2.61 - 30/06/2004.

Yet here:
http://avisynth.org/warpenterprises/
There's a CNRk version dated at 13/3/2005.

What's the difference?
Thanks.

Cheers kedautinh12, CNR2 was always a pretty good filter to have.

Is there any differences comparing the last avisynth release? Or i just need to try a vapoursynth version? Thanks.

I have tried to replace Cnr2 with vsCnr2 and I get the error that scdthr must be between 0 and 100, while my original cnr2 line was

Cnr2(mode="ooo", scdthr=255.0, ln=255, lm=222, un=255, um=255, vn=255, vm=255)

Have I to evaluate those numbers in scale between 0 to 100?

Why you set scdthr parameter very high value when default just 10??

Not my script.

Try compair between vsCnr2 and Cnr2 with value of scdthr

Boulder · 27th October 2022, 13:28

With scdthr at maximum in either case, there will be zero scene changes detected. Normally that would be a very bad idea, but probably there's some logic behind that thinking in the original context.
