DaVinci Resolve for Underwater Videographers: Part IIIa – Color Grading


Welcome to my next tutorial on Davinci
Resolve. On this one we’re gonna be working on color correction and doing a
primary color grade on all of our Clips. To get onto the color page we’re going
to click down the bottom on color, now we get a window like this, yours might be
slightly different there might be keyframes showing down the bottom right
we want to make sure that scopes is showing down here on the right and make
sure it’s on parade, like this. Just to go through everything
up here we’ve got our stills gallery we’ll get to that in a little bit, we can hide
that for now just by clicking on gallery. We’ve got our viewer at the top.
Up here is our node screen which is similar to Photoshop layers but it’s
like a sequence of nodes Down the bottom
we’ve got our scopes which is very important and then we’ve got our color
wheels and our color adjustments at the bottom. Yours also might look a little bit
different, you can either use the primary wheels or the primary bars. I like to use
the primary bars myself. So let’s get started. The first two clips are
actually quite nicely lit already the colors quite nice you can have a look
we’ve got a fairly even balance between our red greens and blues but if you
actually look on the scopes the Reds at the bottom which is like the blacks the
greens and blues are slightly not balanced so we can adjust that using the
offset over here this is how we can sort of fix our white balance so we can bring
down our greens so that they match our reds, we can then bring down our blues so
they match our reds, and this will just do a general fix, all I’m actually
looking is at the scopes at the bottom trying to make these lines all match up
so looking at that and then you can actually have a look at your viewer and
see what you’ve done. You can always do CTRL D which will turn off this node so
you can see we’ve already gone from slightly washed out to the blacks,
looking a little bit blacker we can then now start our adjustments
using these main sliders over here though to adjust the blacks we could
bring all of these down a little bit so it’s closer to zero which is then going
to make the blacks more black so just rolling this one back looking at the
Scopes till it’s about touching yeah they’re a little bit touching you see
the Blues still a little bit off so we could actually maybe roll the blue down
a little bit more and now you can see yet again control D see this was all a
bit blue and washed out it’s already looking a little bit punchy and nice now
if you look at the top of our scopes these are our highlights you can see
there’s not very balanced, Red is a little bit overpowering than green and
the blue we can bring our reds down on our
highlights. Lift is lows, gamma is mids, gain is highlights, so we can bring these
Reds down to try and match these a little bit and maybe the greens down a
little bit.. try and match these all up and now everything’s looking very
naturally colored you can then control the whole of the gains and not while
looking you want to keep this under 1023 sort of closer towards the 896, I think
about that looks nice. Once you’re happy with this this is our primary grade
finished we can right click and go grab still this has basically taken all of
our settings and now put them in our gallery so this one up here is all of
our settings from the last clip. We can then go to our next clip you can right
click on our still and then left click on apply grade and it will
put all of those settings onto here. It hasn’t actually worked too well on this
one you can see the highlights are a little bit wrong and the blacks have
been pushed a bit too far down so what we can do is bring our bring our lift
back up until we’re about the Reds are on the bottom you see the greens and the
blues now are actually slightly off so let’s use our offset again bring our
greens up to match bring our blues up to match okay… So they’re all matching look
at our highlights, maybe the blues are a little bit brighter here
look at these spikes here which maybe bring the blue down a little bit on our
gain on our on our highlights blue down a little bit and I think there
we go if we press control-d again it’s gone from that and it’s really sort of
pushed the blacks down and made everything pop up there are two other
settings you can do I haven’t actually played with the gammas yet the gamma brings up
the the mid-range so you just use the mid-range wheel here to where you like
it, i think i think it’s about fine you can also do it on this
one, we can see what the gamma wheel does they’ll bring off the sort of the mids, I
think it’s kind of nice where it is one other thing you can do just to boost the
colors to make things look a little give it a little bit more punch is increase
the saturation you don’t go crazy with this see if we go up to a hundred now it
looks a very cartoony looks and unnatural
maybe we push this up to like 60 or 60 to 70 I think even that’s a little bit
too much let’s bring it down to 65 okay I really colored but that’s fine on the
next one let’s push the saturation up. This is quite an easy grade because we had good footage to start
with but if you start with some worse footage like these two clips I probably
wouldn’t use I wouldn’t actually be using these on my edit but we’re gonna
use them to see how we can fix this very green very blue footage which is very
common for new videographers that haven’t got the filters or their color balance right, so we
can just use exactly what we just did we can start with the offset
look down here the Reds are minimal if the Reds have gone off the chart that
the greens and and the Blues are here so yet again we can just bring the Reds up
let’s bring the reds so that they’re just touching up here we bring the greens
down until some of the darks stopped touching here
and then then we can bring the Blues down so that’s kind of matching the
green we can then see that the highs up here are a bit low so we could push all
the gain up we’re using the gain bar to brighten the whole scene a little bit
but you see there’s still a lot of greens and blues in the mid-range so we
can try and adjust just the mid-range green and blues by using the gamma and
turning down the green and the blue here so we bring the greens down a little bit
bring the Blues down a little bit we whenever you do this you are suddenly
gonna bring the darks up a bit, so we can crush this down a little bit more
push the blacks down a little bit more see if we can it’s starting to look a
bit too green now so let’s turn the green down a bit more till the
background is going a little bit bluer think about there I think this is about
as good as we can get yet again if you do control D you see we’ve gone from
this to that which is a lot more acceptable and even though it’s not
exactly perfect and just playing around with these bars and checking your scopes
you can make a huge difference we can then right click grab a still we can go
to our next clip dragging along here right click on our still click on apply
grade and there we go anyway see we’ve gone from a very green photo green video
when we brought those Reds up and it’s looking a lot more a lot more colorful
I’ll now quickly do the rest of the clips and there you have it our primary
grading done Thank you for watching and
hope you stay tuned for our next one
