What to do if noise differ ?

Hello.
I've a question. I've a video where sometime there is noise on
frames, sometime there is no noise at all.
When there is noise, it's always "the same", so , a build profile for
the noisy part can easely be build.
Of course, the noise/no noise are so mixed, that it's impossible to
split and process them separately. The mix is not something that
one frame with noise, another without, but it's one full sequence/scene
with noise, the next scene/sequence without noise. I don't understand
how it has been done...
So, if i build a noise profile of the noisy part, and apply the filter to all
the video, what will happend ?
Do you have a suggestion of how to parameter NV to process the whole
file correctly ? Maybe building the noise profile sampling from the noisy
and no noisy part ? Or building the noise profile from noisy part and
customising settings ? Or maybe it's simply not possible ?
Or... something else ?
Thanks.
