Speaker: In this lesson, we're going to learn
how to deal with green screen footage
in Adobe Premiere Pro.
Go ahead and find the green screen dog video
and the green screen Phil video.
You can see here that the green screen dog,
when you're shooting, you want to have
an evenly lit background.
This is much more evenly lit than green screen Phil.
It's a lot darker, and so this one
is going to be a lot easier to fix
or to remove the background,
but I wanna walk you through this one
to show you that you can remove the background
from a difficult image.
First thing's first.
The first thing that I wanna do
when I'm dealing with green screen footage
is actually add the crop effect.
In effects, you can search for crop under transform.
Add that to your footage, and then crop
into your subject as much as possible,
wherever your subject is not.
With this dog, who's sitting very still,
I'm going to crop in the left and the right,
and the top just a bit.
What this is doing is helping Premiere Pro
by basically automatically getting rid
of this part of the background.
The green screen effect that we're using,
the ultra key doesn't have to worry about that at all.
Let's do add that ultra key effect.
It's the best keying effect in Premiere Pro.
Drag that onto your video,
and then we're going to take this key colour picker.
Select this eyedropper.
You can go anywhere on your green screen and pick it.
I generally pick somewhere a little bit darker
because I find that it's easier to make adjustments
and fix the highlights of the green
versus selecting a brighter part of the green
and adjusting the darker part.
Let's just pick something down here,
it's a little bit darker.
We still see a little bit of speckles,
especially if you play through this,
you can see speckles in the background,
and so we need to get rid of some of those.
With this shot, we can easily change the setting
of the ultra key from default to aggressive,
and that's going to automatically fix the issues.
It's a very, very good key already.
To make sure that it's a good key, change the output
from composite to alpha channel
and scrub through and see if there's any parts
where you see shadows within the white,
and I see a little bit.
I'm gonna go here where I see some of those shadows.
I'm going to go to matte generation,
and then where the shadow is,
I'm going to just increase that just a bit
until those shadows disappear.
Then, if that doesn't get all of them,
I see a tiny one right there.
It might be a little bit hard for you to see.
You can play with the tolerance
or the pedestal and see what that does.
Increasing the pedestal seems to be helping out a lot.
Still have a couple shadows right around here.
Let's see if increasing the shadows even more helps.
That seems to do that.
You also wanna make sure that there's no speckles
in the black, and if there are,
you would adjust this highlight,
and we're going to be using that
for the green screen Phil shot in just a second,
but if we go back from,
I'll put alpha channel to composite.
This is a good to go green screen shot of this dog,
and we'll start adding backgrounds
and talking about that in the next lesson.
Let's jump over to the green screen Phil shot.
The first thing we are going to do, again, is crop this.
With the crop effect, I'm going to add it.
I'm going to crop the left in.
I'm going to crop the top in.
We obviously have to get rid
of the edges of this clip because
this green screen didn't cover my entire background,
and then crop in the right side just like that.
As much as possible.
When you're shooting, though, you have to be careful
of moving your hands so that your hands don't go
over the edge of the green screen.
This looks pretty good.
I might be able to drag in the left
just a little bit more.
Okay.
Now, let's add the ultra key.
We're gonna put the ultra key on our clip.
We need to take our colour picker,
choose somewhere down here in the darks.
You still get a lot of
the highlighted green screen appearing,
The reason is because the lighting
of the green screen was not amazing.
This was a quick job.
This was a test, and I didn't really
put up actual lighting, and that's why it's so uneven,
but we can still make this better.
We're going to first change the setting
from default to aggressive.
That helps get rid of some of it,
then we're going to go change
from composite to alpha channel.
Here, you can really see the speckles in the black.
We're going to drop the highlights down all the way.
Play with the shadows,
and then play with the pedestal.
Increasing the pedestal.
Then we're just gonna go through,
scrub through just a bit to make sure
that there weren't any other spots
where shadows are shining through
either on my face or speckles in the background,
and that seems to have done a really good job.
Then I'm going to change this alpha channel
back to composite.
This looks really good.
One thing I notice, it's very subtle,
but I do see a little bit of a green edge
around my hair, and we can really notice,
and one thing I encourage you to do
is actually add a white background while you are doing this
just to make sure you're green screen is looking good.
I'm going to click this new item button,
go to colour matte, say okay,
and select white.
We'll call this white matte.
Then I'm going to put this underneath
my green screen footage.
Looking pretty good.
It's even harder, actually, to see that green edge
with the white, so that's good.
I'm just gonna go back to this shot
with black background, and to fix that edge,
there are a couple things.
We can go down to matte clean up.
The choke and the soften
will actually increase or decrease the edge.
Let me show you the alpha channel
so you can see that better.
Choke, soften, so increasing the choke,
softening it up.
It will make your edges a little bit more soft.
With the white background, you can see
that looks really funky.
I would never go that much, but sometimes,
if you do want to decrease the edges
just a little bit, this can help.
It's pretty hard to see the green edges
with the white background, so I might
not even need to do this, but it's good
to know that when you do have some green highlights
because of some green light bouncing
off of the green screen, you can go to spill suppression
and increase the desaturation just a little bit.
If you go too far, you can see
that the entire image becomes desaturated,
but just doing it a little bit will help it a lot.
This is how we remove green screen backgrounds
in Premiere Pro.
In the next lesson, we're going
to be adding backgrounds and making it look good
with a background, because this is just the first step,
removing the background, now we have to add
a background that we want,
but make it look natural.
