Plugin to show just the noise on a clip?

[rkalwaitis]

Is there a plugin or a simple script that will show me the noise on a clip, perferably in a different color or in an easy way to see?

next does supersampling go like this

Someresizer(1440,960).sharpen(1.0).someresizer(720,480)

crop()

can you crop before and adjust sizes or is it best to crop after.

thanks:thanks:

I don't think so? How would it distinguish detail vs. noise?

If you have a reference clip, you can return difference masks, or difference layers to visually see pixel differences

Poisondeathray, I don't know how it would tell the difference. A denoiser does. So there is a method to find it, so now I think we just display the difference like you said and not denoise it so I can be seen. Maybe? I know some sharpeners can sharpen noise, maybe that is a way to do it.

I don't think so. All denoisers reduce "wanted detail" by some amount too, along with "unwanted noise". It's impossible to perfectly distinguish the two. Unless you have a super secret perfect denoiser to share with us?

e.g. some people would label film "Grain" as unwanted noise, but others want to keep it and consider it detail. How do you distinguish the two?

You can visualize what a given denoiser thinks is noise:

orig=YourSourceFilter("file")
denoised=orig.YourDenoiser()
subtract(orig,denoised)

Thanks Neuron and poisondeathray.
