Hey there good people, my name is Scott and you're watching Sword & Shield Studio. Right
now we are going to learn how to use Power Windows to selectively color grade your video
on the color page in DaVinci Resolve. Let's see how it's done. Alright, so the first thing
you will need to do is navigate to the color page in Resolve where I am now and select
the clip that you want to color grade from the clips window down here. You might have
a bunch of different clips , in my case I have just the one from a previous YouTube
video. So I'm left click and select that and then you can save yourself some screen space
by closing the clips window at the top here and the gallery window at the top left here.
And before I begin using Power Windows to selectively color grade I'm going to quickly
white balance my image by going down to the eyedropper above my color wheels at the bottom
left here. It will say 'White Balance' when you hover over it. Left click that and then
I'm going to select a generally neutral point on my white shirt here. And then you will
see there are bars underneath the node indicating that adjustments were made, and I am going
to hit 'Alt+S' to add a new serial node after that node that I just white balanced on. It's
generally a good idea to keep different kinds of adjustments in separate nodes like this.
Next, let's start selectively grading this with Power Windows. To get to the Power Windows,
hit the circle icon here above the curve graph. It will say 'Windows' when you hover over
it. Select any preset shapes you like, we've got a linear rectangle, circle, polygon line,
curve, and a gradient. In my case I am going to select a circle because ultimately what
I would like to do here is increase the exposure of myself in the foreground and darken the
background to create some separation in my image. So I will select the circle, and you'll
see we get the power window over our image here and I'm just going to first shape this
first circle around my head. Then I will adjust the softness, bring up the softness quite
a bit actually so it's not such a hard edge. And then I am going to click this icon here
with the circle and the plus sign to add another power window and I'm going to adjust that
for my chest, just slightly smaller than my shoulders there and increase the softness
again. Now that I've defined the general area that I want to adjust I can start making some
changes. I'm going to bump up the gain here on my slider until just before on my scopes
it clips off. You don't want it to go at 1023 here and clip off, you want it just below
so you're not losing any color information. Maybe I'll increase the gamma just a slight
bit, .02 maybe. I think that looks good. Then I'll increase the saturation amount just a
touch to bring back some of the color in my skin that might have been lost by adjusting
the exposure. Now if you want, at this point you can track the power window that's around
your face to match your movement. You can do this by left clicking the power window
you want to track to make it active. Make sure you're at the beginning of your clip.
Click the tracker icon down here and then hit this play icon to the right if you're
at the beginning of the clip to track forward. Then you'll see Resolve will match the movement
and scale and position, everything with this power window to match the movement of your
face. I'm just going to disable my power window preview here to see how that looks. And this
is pretty good. In my case it adds a bit of an undesirable exposure to the back wall here
which I don't want. So, if this were a more in-depth project for a client I would create
a power window that exactly matches the shape of my face and track it that way. But since
this is just for YouTube I am going to hit 'Ctrl+Z' and undo the tracking and just position
the power window in an average spot where my face would be most of the time. The next
thing I want to do with this image is darken the background slightly to create even more
separation and have myself stand out from the background. In order to do that, select
the node that you created the power windows with here on the right and hit 'Alt+O' on
your keyboard to create an outside node. So what the outside node does is it just selects
everything outside of what was selected in the previous node which is our power windows.
So this will select the background. Here I will just reduce the gamma a slight bit where
I'm not crushing the shadow too much, it's just a bit darker. And then I will introduce
a color boost just to slightly bring back color in the poster and the light behind me.
Another thing I can do is introduce a slight blur to the outside node to create even more
separation by clicking the teardrop/triangle icon here, it will say blur when you hover
over it. Make sure you still have the outside node selected. I'm just going to bring this
up to .54. Now, if you want to see the difference between your original image and your graded
one you can just select the various nodes you made adjustments to and hit 'Ctrl+D' on
your keyboard to disable it. So we can see how the background is affected by the outside
node and then if I select the power window node here and disable it you can see the complete
before-and-after. As you can see that makes a huge difference. That does it for this tutorial,
I hope that you learned a bit about the basics of how you use power windows and how you can
use them to selectively color grade parts of your video. If you did, please consider
subscribing to the channel where I upload a video just like this one every week. In
addition, Sword & Shield Studio goes live every Sunday night where I'll be answering
questions and working on something in Fusion, so be on the lookout for that. Thanks for
watching, I'll see you next time.
