in today's video I'm gonna be talking about how to do a proper more advanced
noise reduction on the noisy footage and before we start I want to say special
thank you to ruff film for providing this fantastic footage for this tutorial
make sure to check them out link in the description below
alright here we are inside DaVinci Resolve and I'm gonna show you really
fantastic technique that you can use to basically clean up any footage now
before you do it it's recommended that you're actually working on the rec 709
or whatever you output is because when image just in log right now a lot of
times you can't really see what's going on
so once you convert basically once you give you the color in the contrast in
that case you can see much better what the hell is going on and go back and fix
it so again we're working from with the shot from raw film over here and I'm
gonna convert it into nice cinematic rec.709 I'm gonna do I PP to red white
gamut red lock film okay that's gonna be my
settings and to convert it I'm gonna use my lot that I just released film lot
boom and right away we have very nice starting point now I'm gonna do another
note let's do vector scope really quick and I'm gonna adjust a little bit kind
of a neutral white point make it a little bit cinematic alright perfect so
here we have it ready to roll now when i zoom in I can see there's a lot of crazy
noise going on right over here now we can finally see the first thing we need
to do is get rid of the chroma noise because chroma noise is real annoying
chroma noise is very simple spacial threshold new on I'm getting them and
just increase chroma to about 10 or 15 don't go too much because you may affect
actual colors okay so that takes care of the chroma noise let me show you right
away before and after huge difference now the actual problem the actual
problem we have is with aluminized and we can see it's
very pronounced very annoying so here's a solution and by the way what I'm gonna
show you is more like a higher end noise reduction if you have a weak computer it
probably will make your computer stall this technique is for really beefed up
systems that completely powered you know with the tons of RAM great graphics card
stuff like that so I pushed alt why and I basically created separate RGB if you
don't know how to do this go to the color let's see da-da-da-da-da notes and
let's see alt Y there we go at splitter combiner and it creates separate RGB we
can see red green blue and let me label them for you a green and blue so now we
have our shot basically split into three different channels that being combined
together creating a nice RGB image okay so what I'm gonna do I'm gonna start
cleaning each channel individually so I'm gonna go to open effects and I'm
gonna use neat video neat video is external plugin unfortunately the
built-in DaVinci Resolve plugin is that accurate and not powerful so therefore
it can't really do that good of a job thing is you need to know when you apply
this plug and find a spot on your shot that doesn't have any movement doesn't
have any kind of crazy fine detail something that solid single color kind
of a corner over here that would be perfect okay
click outer profile Auto Tune and apply and we can see right away
before and after we can see how great difference this
thing makes before and after and we can see that it doesn't affect the quality
of the image so that was the red channel let's go to the green Channel I'm gonna
do the same thing okay same corner like that out of profile
auto-tune apply again I'm doing a little bit quick and dirty if you spend a
little bit more time you probably can get slightly better result but needs
video works fantastically in automatic mode and by the way this is not any kind
of advertisement I've been using neat video for my personal work for years now
so finally we're gonna do the same thing with the blue Channel okay just like
this and again we can see blue channel clean green channel clean it's all good
so what I'm gonna do now I'm gonna exit RGB and prepare for your computer to
start going really really crazy because it's gonna take a lot of processing
juice to start calculating all this right click create compiled note there
we have it and I'm gonna call this one oops what did I do
right-click create compound right-click note label and our noise reduction and
basically we cleaned up our shot very good as you can see the you know this
thing is pretty practically unusable at this point even though I have very very
beefy computer when you do three neat videos basically on one shot that's what
you get unfortunately that's why you turn on a
render caching if you don't know how to do render caching I have the video I'm
gonna post it in the cards above okay so here we have it here's the guy let's
focus on his back really quick I'm gonna turn it off okay let's wait a second and
we're gonna see there we go see how much grain and noise on his skin we can see
it in the arm once I turn it on it's gonna be much
much cleaner give it a second to start calculating all that information DaVinci
Resolve bug and here we have it very nice and clean so this is the higher-end
technique for reducing noise it's obviously very depending on you
demanding on your computer so when you do that keep in mind if you have a long
project it would be better off for you just to render that clip and then paste
it instead of the original clip that way your whole system not gonna be going
crazy once you're working thank you guys for

see you guys soon take care
