Green Screen or Chroma Key Effect in DaVinci Resolve 16 Free | files included for Beginners

hi I'm Chil from sharing your passion

calm my mission is to help you transform

your passions into success in this

tutorial we are going to take this green

screen talking head of me and turn it

into a dynamic video with different

image backgrounds and a moving video

background we will be using DaVinci

Resolve 16 the best completely free

highly advanced video editor okay here

we are in the Vinci resolve sixteens

edit page or edit tab the first thing we

need to do is bring in our assets our

videos and images okay so here we go I

have six items I just have to drag it

into our media pool there they are now

that we have our assets our graphics and

videos in our media pool we can drag our

main green screen video down to the

track okay

our timeline okay so it's in video one

but you know what it shouldn't be in

video one it should be in video two we

need to bring the green screen up

another layer to video two but there's

no video two so we just right-click this

area add track created the video - and

let's drag this up let's play this in

this exercise we don't need the audio so

I'm going to click the M here to mute it

so this is our main green screen video

okay so the next thing we need to do is

turn this green screen background into a

transparency and we can do that by going

here in the color tab color page this

page looks pretty intimidating there's a

lot of stuff going on here but we don't

need all this stuff right now all we

need is to turn the green background

into a transparency so what we need to

do is go over here this is the node

window I'm not going to explain the

details about nodes right now all we

need to do is just turn that to

transparency so just go here right click

and add alpha output an alpha is like a

layer that you can turn into a

transparency and what we need to do is

drag this blue dot here over to here

connect it to the output this is input

this is output what happens in the

middle are all the effects we can add to

this clip so all we're doing here is

adding a transparency so next make sure

this dropper is highlighted left click

it's highlighted make sure this dropper

with the target there is highlighted and

now click the green screen area I'm just

going to give it one click here so what

that did is select the green areas that

were similar to the point we clicked

here but because there were other darker

greens or lighter greens going on it

only selected a narrow area a narrow

range of greenness where we clicked so

what we have to do is expand the green

range that we want we can do that by

going down here and adjusting the hue

saturation and luminance okay let's do

that by going over here see that's a

narrow band of green that was selected

we need to expand that by dragging this

to the left see that now there's more

green being captured so let's bring it

to about there so look at that now we

have a really clear-cut green area but

there's some stuff here that's remaining

we can probably catch that through

adjusting the saturation and luminance

so let's drag this saturation to the

left ok it caught that see if we go too

narrow and there's a lot of green that

it doesn't capture but if we go wider

then it caught that and we don't even

need to adjust the luminance so

but just to show you if I drag this

around play with it it will affect

things so in other situations with

different lighting different green

backgrounds you might need to adjust all

three until you you capture all the

green range you want so that's pretty

clean so what we've done is capture all

the green areas we wanted to get rid of

but what's showing is only the green

part what we want to do is reverse it we

want this area to show and the green to

disappear and we can reverse that by

clicking this little icon here there you

go so now I'm showing and all the green

stuff is gone and it's perfect so let's

go back over to the Edit Page okay we're

now back in the Edit page and let's play

this so all the green areas are gone the

only thing you can notice are a little

bit of greenness around the edges of my

face and ears and you could probably fix

that going back to the color page but

you know what that's fine it's probably

not going to be a big deal let's bring

the playhead back here so the next step

let's bring our four images down let's

highlight all four of them drag it down

to video one and look at that now we

have a background let's play this

that looks pretty good and now let's

bring down our video background okay

right over here let's mute this we don't

need the audio of the video let's play

this from this point and there we have

it we now have a video background as

well I disappeared because the

green-screen talking head was only up to

this point and the video background

extended beyond it

so what we can do is just cut that off

by bringing the playhead here

highlighting the video background and

control B to cut with the blade

highlight this section and delete now we

have a matching ending okay let's go

back to the beginning and play this with

the images and the video background

okay with the brick with the wood and

now that video coming in there you go so

that's how the green screen effect works

in da Vinci in some cases you want your

talking head right there this size big

and in the center but in other cases you

want it small off to the corner either

here here any corner but resize down to

a smaller talking head so that's what

we're gonna do now normally you resize

images or graphics by controlling the

zoom let's highlight this talking head

video here and now we can control the

zoom I can make it bigger by dragging it

to the right the X to the right or I can

make it smaller by dragging it to the

left but now it's making the whole frame

smaller the background is not shrinking

but the visible area has shrunk so we

need to take another step to avoid this

problem let's set the zoom back to 1:1

enter and we have to go back to the

color panel the color tab click this

around icon here it's the window icon

see window select the rectangle or

square here and now we have to resize

this rectangle around our talking head

there's two ways to resize one uses

ingredient this is the outer edge the

outer dots let me drag this outer dot

and you can see it's a gradient the

opacity is full here and it fades out

but we don't want that we want the full

opacity so let's bring that back what we

have to do is drag the inner dots around

our profile around our talking head so

let's drag that down can't drag this

over here and drag that up there drag

this here okay I think that's good let's

go back to the Edit tab and now when I

adjust the zoom drag to the right drag

to the left and it's no longer cutting

off the

edges of the screen so it's only

controlling the area we highlighted in

the color tab so now we can resize this

down change the position I'll drag the X

to the right and the Y down to the left

which brings it down a little more over

to the right okay so now my talking head

is smaller out of the way and now we

have this whole area to focus on let's

play this okay so now you can highlight

this section here you can have text or

other kinds of information going on in

the middle and your talking head is just

to the side before we end this I noticed

one little problem in some of the images

not in this image this image is full

size but when you get over to this next

image there's some black areas showing

that means the resolution or the aspect

ratio of this image wasn't filling up

the sixteen by nine screen this is

probably a four by three aspect so it's

not filling out the full sixteen by nine

image it's an easy fix

let's just increase the timeline zoom

here by clicking the plus two times and

let's go over here and all we have to do

is select this image and zoom in okay

I'm dragging it to the right until it

fills up the space okay the next one

next image again it's smaller aspect

ratio that's not covering the full image

it's why the black area showing let's

zoom in for that highlight the brick

zoom in okay and highlight the wood over

here change the timeline back here and

zoom in okay so now I think this is

perfect let's run this from the

beginning

we have the lounge now we have the brick

could have nice stuff going on here nice

imagery or text going on and we have the

video moving background and there we go

that's how we do green screen effect or

chrome effect in DaVinci Resolve 16
