Hello, everyone, and welcome to NewTek Tuesday Tutorials.
I am your host, Richard Evans.

I'd like to show you the show alpha utility and TriCaster.
Pulling a good key from a green screen can be difficult at times.
It takes lights, cameras and helpful tools to help
create a good keyed shot to embed into a virtual set or other effect.
Now, the TriCaster show alpha utility is yet another easy
to use tool in an already expansive toolbox to make this happen.
So let me show you how it's done son.
All right, so here we are.
In the TriCaster 2 Elite interface and what I want to do for today's show
Alpha overlay example is I'm going to put my armored soldier man
here on input number two and embed him into my mix effects number one.
OK, so you'll see in this particular shot, I'm only using two lights today.
I'm not using my overheads or anything, which is what I usually recommend.
Doing more lights the better.
But I just wanted to show you this for an example.
OK, so the first thing that we're going to need to do is to pull a key
to green screen that out and put him in, make that transparent
so I could throw them onto this virtual set.
So to do that will open up the configuration app
for input to let me move this out of the way A little bit.
All right.
And so what I have is on my image tab will go down to keying here
and have already selected
this color via the ink dropper, but I wanted to show you something here.
Let me go ahead and turn on.
All right.
And at first glance, looking at this, that looks kind of OK.
I mean, it's dark and this is a dark subjects.
We can't really see the edges, OK?
And if you look over here on my mix effect,
no one that I have selected on program, it looks decent.
But if we look closer in here, let's go ahead and zoom in on that mix effect.
Like you can kind of see some dark edges here in the corner. OK.
So what we want to do is get rid of those,
and it's kind of hard for me to see just here with black and on dark subjects.
So to do that,
we're going to put on the show alpha overlay and you can select the show
alpha overlay on any input media player mix effect program preview, you name it.
What I'll do is I'll just right click on input number two itself.
And we'll go to the very bottom here over under overlays.
There we go.
And then go down here to show Alpha and then check this out.
So this will show you
an inverse of what you would see here in a black and white format.
And you could see I have a lot of shadows in here that I need to get rid of.
So basically, you want to have your background
be as dark as possible when you're doing it in the show alpha
side of things, because anything that is like white or gray will show up on screen.
So eventually what we want to do is just make our statue man here all white.
So to do that, we'll go back into our setting here.
And then with this, it's going to be a little bit of playing around with this.
This is kind of an art form
as far as like adjusting the tolerance, a smoothness, et cetera.
So what we're going to do and here is just kind of play around
with these settings until we make this gentleman all white. In
fact, let me go ahead and bring the show alpha on top of the preview as well.
So there we go.
So now it's in both spots, so we can kind of see that little bit better.
All right.
OK, so now let's go ahead and start to mess with these.
I'm just going to mess with the tolerance here, and let's just crank that up a bit.
And as I crank that up, you'll see that those shadows start to disappear.
So let's keep cranking it up until we get all white banned.
So that's looking pretty good.
And now over here, let's go ahead and take the alpha channel off,
so we want to leave it on there.
All show unless you want to. It's up to you.
Same thing.
We'll take it off this one. Bam.
All right.
So there you go.
And now my armored gentleman can give his speech
from the steps of the City Hall, et cetera.
And they were pretty much good to go.
So that looks a lot better from what we had it on there before.
Let me just go ahead and put it back
to how I had it, just so you can kind of see the difference.
So you can see there, that's where we don't have anything adjusted
and then as where we have that adjusted pretty good.
And that show Alpha Overlay is super helpful in finding those out
helps me out making green screen shots looking great.
So again, there's a little bit of an art form on the playing
with the levels of your green screen, but this is a really good way to help
you adjust your green screen shot
and pull a really good key and have a really nice virtual set like I got here.
All right, go ahead with your speech man.
Again, pull a good key, take some finesse, but TriCaster gives you
the tools to make it happen.
