Lightworks: Green Screen Keying (Part 13) Video Lecture | Lightworks Video Editing: Basics to Pro - Video & Sound Editing

hey guys this is Divi with another white
works tutorial in this light works
tutorial segment we're going to be
discussing chroma key and green-screen
keying within though it works beta
program so get started here we've
imported our video clips that we're
going to need and we've placed them in a
permanent bin this process is discussed
in the previous tutorial if you're
curious on how to accomplish that so the
first thing now that we want to do is go
ahead and open up a new edit which is
edit 11 and it opens up a new window we
want to go ahead and drag our
green-screen cropped wire in to the Edit
window just like that we crop this just
using masks the mask tool in Vegas Pro
just to cut it down to make it a little
bit different because our original clip
had all this lighting and stuff off to
the side so we just wanted to kind of
clean that up and just have the green
layer that we needed I didn't really
want to mess around with this in light
works because I just wanted to get this
tutorial done because a couple people
had requested it via YouTube I just
wanted to get something up there for
everybody to actually learn how to do
the green screen effect not all this
extra stuff with masks although it's
probably possible in this program I just
haven't gotten a chance to try it out so
what we want to go ahead and do next is
add another video layer right below
video layer one so what we do is we
right click on the timeline click add
tracks select the number of tracks to
add which we just want one video track
we'll just leave the name automatic and
our location is gonna be after v1 so
that way it's located between v1 and
audio one click on do it and then that
opens up the track that we need now the
next thing that we have to do is to set
our in out points on the timeline for
our background image or video clip in
this case so we do video in and video
out actually video as you can get all
the way at the end ok and then what we
want to do is prepare our background
video or image so we're going to turn
off video clip one popping this out here
selecting our in and out points so we're
just going to clear those in and out and
then we're just going to
leave this right here and all we're
going to do is press Alt alt V and it's
going to place it right onto the
timeline okay so now your green screen
background layer is selected you want to
go ahead and turn that off and turn on
your green screen layer on the timeline
click on the effects tab and then you
can select the green screen key for the
current clip then you have a bunch of
different options that open up you can
use the eyedropper tool just to select
your green color and then you can use
its saturation hue and luminance herb
tools just to make some adjustments and
gradually your video will become clearer
in the background will be able to be
see-through through the green screen um
and then you can also adjust your spill
suppression and also adjust the key
smoothness which will really make out
the video look more realistic because it
will smooth out the edges on your green
screen clip like around the shirt so
basically you really have a good effect
here you can zoom out on the timeline
turn your layers on then you're ready to
render your video hopefully this helped
you guys out who had questions about
green screen and chroma key in light
works and um subscribe to stay tuned for
our next tutorial thanks guys
