hello my friends and welcome to another cool davinci resolve tutorial
and today we're filming on blackmagic pocket
4k model and i'm gonna show you what to do just in case you under
exposed your shot and it happens quite a lot in the industry sometimes you
underexpose or sometimes you forget to change exposure for example or
you move from one location another one and just by whatever way you forgot to
change your aperture or adjust for different lighting so in this video
i'm going to show you easy trick that cost you absolutely nothing
that you can do in order to absolutely fix that
so let's get started all right so let's say a situation you're filming
dark at night and your footage looks dark so you take
it to the video editing application in our case it's davinci resolve
and you have a lot of great if you're familiar with audio editing
you know that in audio editing and audio recording there's
thing that called room tone now room tone can be used for various
applications and one of the applications can be to
grab the signature of the room tone and later in post use it to remove
unwanted noise whether it's a refrigerator a fan of
air conditioner or whatever well we can do
exactly the same with the video and i'm going to show you
how to do this so here i have a piece of paper okay
let's say that you're filming and you know
that you don't have lighting and in the future
you may have problem with the noise so what we can do we can capture that room
tone just with a simple piece of paper now you can use technically for this
anything however white piece of paper be sure
that there is no texture on it there is no writing on it
it's just a clean white piece of paper that
you can use this thing to capture your noise signature and later completely get
rid of it so only thing you need to do let's say
you're filming in a dark environment ask your talent whatever the shot gonna
be to hold this paper for one second right in front of them make sure you
focus on this paper and then in the post and i'm gonna show
you in a second you can completely get rid of the noise so let's jump in
davinci resolve and i'm going to show you
exactly how to do this it's very easy and very effective method all right so
here we are in davinci resolve and i have couple clips for you one is
dnx hr and another one blackmagic raw that way i kind of show you the concept
in both clips so here is very same from
the introduction that you've seen here's gorgeous
beautiful me holding piece of paper okay so let's say
this shot right here we have a nice clean texture and if we zoom in we can
see that indeed this part right over here
has a lot of noise and it's very clean it's a solid piece
and you can use technically whatever the hell you want
piece of plastic credit card if your card is you know
solid without any texture on it note cards whatever you like okay
so let's say you finish color grading or color correcting and now you got to
get rid of this noise so what we're gonna do
in the end of your color correction and by the way it depends i made the video
about it uh like a year and a half back
where i was presenting whether you do no noise reduction in the beginning or
in the end it actually depends in our case
let's say assuming we're doing in the end
of the color grading process so here we have it and we're gonna use
neat video it's fantastic plug-in uh i'm not being sponsored by it
those guys have no idea i'm doing the video it's just my personal
favorite plugin i've been using for years and
it's really been saving my ass on commercials feature films
you name it this this thing is really incredible
anyways so we're gonna drag this neat video on our last note
and let's do prepare noise profile so what you have to do very simple
select a square if we're not gonna go too much into
details so let's see that this looks the most neutral to me i'm
guessing okay and you can see the amount of noise
in the little squares okay and let's click build profile
if you want to do a little bit more advanced
go to adjust and review and we can do it a little bit manually i'm going to show
you so let's select hi be careful you really
need to have a very powerful computer now temporal noise let's click
on it and it's going to show us basically what we're looking for so this
is ideal so we kind of have a little bit noise on
the edges okay so let's click begin and we can see
that this is exactly what i have okay so let's finish now
it's very important noise reduction amount
okay don't really mess with this i don't recommend
but very important is local flicker okay let's click begin on that
one and if we're gonna click on the question mark it's basically gonna
show us identical situation here and we can see that in this case i
probably should dial a little bit more so something probably
something like that so our value gonna be nine so let's
click finish and let's click apply and here we have
it so you can see my beautiful ginger beard
over here and let's toggle before and after so we can really see
how much damage does this plug-in does and we can
see there is absolutely no damage the amount
of details remain identical after the noise
reduction so if we're going to look at the whole picture
look at that it's very nice and clean so let's check it out
here before and after so
this is really fantastic the same thing let's do
in the raw settings so this was shot with iso 200
um let's just probably do 1000 that's a huge
jump or we can say huge jump and we can see that
i'm focusing from one object to another one but if we zoom in
we have a lot of noise in the blacks and by the way ideally you
probably should have a proper gray card that would be ideal for capturing noise
or plastic little black card but it doesn't really matter
piece of paper on the budget works so we're gonna do similar thing here we're
gonna do new note we're gonna go reduce noise
click here let's do the profile so let's select something
over here oh by the way what am i doing wrong
let's focus on the paper that way we get as much information as possible to
capture a clean profile okay
so something like that over here we can see all the little
noise let's click build profile again let's do quality higher because we
want perfect frame so let's begin here that
looks perfect local flicker begin
we probably can dial a tiny bit more so six in this case let's click apply
and here we have it let's zoom in in the area where we had a lot of noise
so let's toggle before and after so let me show you that way you can see how
big of a difference it makes before and after and just like in very first
case the image remains absolutely clean
and like i said this thing saved my ass millions of times in my whole filmmaking
and colorist career i hope you guys enjoyed this tutorial
