is there a program that can tell you the % of the video noise to take off?

[kurt476]

is there a video program that will tell you the % off the noise. things like sharpen too take off or too put on?. so it's the right amount. i like that kind of program too tell me what filters i shuld be using.
dose any budy know a program that dose that?

No program can match the human brain, or at least, most human brains. :D

[kurt476]

hehehe very funny man. That's not What i ment. what i ment was you can't tell by just looking at video and say it's all clear witch it is not. i prefer a program that can tell me what filters too use and what the right amount of noise i shuld be taking off.

Please define "noise" so that I can tell my program how to recognize it. Thank you.

i will soon post a picture of the still image soon

that's the point

if there was a filter that detects noise and removes it and nothing else
then we wouldn't have so many filters here, just that one

you yourself must know how and howmuch you wanna process your image
because you allway destroy information when removign noise, so you must decide to remove more noise and destroy more detail, or destroy less detail but keep more noise

[kurt476]

well i would like too convert the anolog images too diglat i think that how you spell diglat ?. it need too anlizy the video it depends on the noise and staic too and chroma and things i just wish there was 1 filter too do every thing i need. i think every other image of the video has more noise then most of them.

well yeah why the hack do we have soo many filters? i been asking that same ? my self. lol

yeah destroy more and less of the noise would be good so that the video is just right like a dvd.

as you can see those are the type of noises i am getting

that last screen shot i don't know if it is a color noise but it changes like too blues, green some other colors.

i gues you mean "digital"

you'll have to try different filters with different parameters
else you won't get satisfying results

there some anime filters and functions you might wanna try

"just like dvd"
there are some very ugly DVDs

[kurt476]

can you give me a web site too these filters i can't seem too find the filters or the webs?

yes i do mean digital

[kurt476]

@neuron2 did you see what i said about the 3 types of noise?

[Guest]

There is no one do-it-all-perfect filter. If you post a link to a short source clip, we will happily advise you on how to process that particular clip. The only general advice I would give is to not over-filter, an affliction I call "filteritis".

[kurt476]

you mean attach the file?

[kurt476]

ok

i think i figure out i like those smart filters those are very good!. do you think you can make a smart chroma smoother or smart chroma reduction filter?

I know the big problem for a denoising filter is to know what is noise and what is not, but maybe it would make sense to add a function "keep noise only" like the denoisers of audio programs have got.
I know that this could be done by some comparison scrips with avisynth but it would be more comfortable to have this within a VirtualDub filter directly.
I know of one filter that has this function: Wavelet noise reduction from thejam79.
It helps configuring the filter and you can see the data that gets removed by the filter.

for that just replace
*noisefilter*(*parameters*)
with
subtract(*noisefilter*(*parameters*))
or
subtract(*noisefilter*(*parameters*)).invert

that'll show the difference
