All language subtitles for 22. Green screen. Best practices

So I hope you enjoyed that preview of what can be done with a green screen.

Now, strictly speaking, you probably already had a kind of a good idea of how a green screen works.

But what I would like to do now before we jump into the next tutorial where we will actually apply the

Chroma key settings to our green screen footage.

I want to cover a few aspects that you should definitely consider when it comes to working with green

screens, and that will be done in this very brief PowerPoint presentation that I've put together for

you.

So there's really only four main steps that have to be taken in order to end up with a successful green

screen VIDEO.

First of all, you just shoot the video with the green screen, then you imports that media into the

video editor.

You apply the Chroma key and a few settings as well.

And then you just export the video.

So it's only four main steps.

But I suppose before you do any of the steps here, there's one crucial step that you have to get right

and that is creating a green screen background.

Now there's a few different ways of doing this.

You can go out and you can buy a green screen, as you probably already know.

Or you could quite possibly do a painting option where you would just paint a wall or maybe some cardboard

or something like that, or what have you choose to paint?

But if you're wondering what the color is, the exact color is a color called green chroma key, which

is also known as Candy Apple Green.

Now, if you were to go to a hardware store and it really depends, I suppose, where you live and what

store you go to.

This color can be quite difficult to get a hold of, and you may have to resort to buying online so

the likes of Amazon or eBay.

But the good news is you can just mix blue and yellow together until you get as close to green chroma

key as you can.

So that being said, I just want to say that the color of green does not need to be exact.

And the truth being told, you can actually use any color that you want.

It's just when it comes to green chroma key.

It's quite a red color, and I think it was chosen right at the beginning when they came up with this

technology because it's quite a red color.

You don't really see Green Chroma key very often.

And I suppose they wanted a very rare color because there would be less chance that the subject, whether

it be a person or an item, would actually have that color on them or it.

So there would be no clashing between the background.

Or I should rather say there would be a distinction between the background and the subjects in the foreground.

Another popular color is blue.

But generally speaking, most green screens are green, and if you are going to go down the painting

route, then I suggest you use latex types of paint because they work best.

And apparently they don't reflect that much because when it comes to the green screen reflecting and

they can reflect, they can mess around with the quality of the video.

So just be aware of that.

Now, like I mentioned, you can go out and buy a certain green screen product.

So this is a good example here.

And I'm probably one of the more expensive options, though I think something like this would cost around

$100.

So it depends on what you view as being expensive in terms of lighting.

The best lighting that I've heard of is probably already lighting.

Now I don't do much green screen work myself.

In fact, I haven't really done any in a number of years, but I do remember that the best lighting

was already lighting.

And generally speaking, LED lights are just great for filming anyway, because the latest just really

soft and it just disperses that light around the film scene.

Nice and evenly added, and it just looks nice.

So here's a good example of some LED lights now.

These ones do look quite expensive, but there are some sort of cheaper ones out there that can do pretty

much the same thing.

You also get these types of lights that are predominantly used with the likes of photography, and I

would say these types of lights work well as well.

And if you're wondering what the key word is for this, if you want to go, maybe take a look at these

types of lights on the likes of eBay or Amazon.

I suppose you could just put in photography, lighting or something like that, and you will find something

like this eventually.

In fact, I have no doubt this going to be thousands of different options that you can choose from.

I've put this really good illustration together of what quite possibly is the ideal set up when it comes

to your subjects in the foreground, the lighting behind the subjects and then the green screen in the

background.

So in this particular example, I've just got this wall that I have quote-unquote painted.

So this is the green screen set up for this particular scenario.

So we have these two light sources here, and we can just view these light sources as being LED lights.

And as you can see, they are like bars.

Now, the reason why I place them like this is just to make sure that we have that even distribution

of light on the green screen.

And as we go through these slides, I will get to a certain slide where I will show you what happens

if you don't get the the lighting.

Correct.

So we'll get there in a second.

So this is another set up now, you don't have to have the lighting exactly like this, so maybe lights

in every single corner.

But generally speaking, what I've what I'm trying to do here is just once again suggest that you need

to get the lighting as even as possible on the green screen.

So I think that's pretty straightforward.

So here we have an example where we have one light source that is missing and we have this darker patch

here because obviously we're missing the light.

So when you actually come to processing this video and applying the Chroma key, you might you may find

that this dark patch will again just mess around with the quality.

And with these types of shadows, they often come up as a green kind of shadow that shows up in your

video.

And the more you deal with green screens and and in particular, bad green screen footage, you'll know

exactly what I mean.

So it's definitely worth just trying to get your lighting correct right from the start.

So you have as few problems as possible when it comes to actually applying the the Chroma key.

And then when all is said and done, you should end up with a very high quality video that looks something

like this.

OK, so that's everything I wanted to explain with my PowerPoints.

Now we're going to move over into the next tutorial where I said we were actually going to apply a chroma

key to some green screen footage.

So I'll see you in the next tutorial.
