I'm excited because I just got another piece of kit in the mail today. Aa sheet of
cotton, and not just any sheet of cotton, but a green screen.
You might remember how my channel looked and sounded when I started several
months ago. My set was okay, but my audio was terrible due to poor room
acoustics, and having the wrong microphone. I set up a studio of sorts in
my basement due to better acoustics but lighting and
visuals were poor. I quickly got to work to fix the lighting and purchased a
muslin backdrop as a quick fix to the problem.
Well the backdrop looked better than an unfinished basement with concrete and
styrofoam. The color was not the best andI was getting bored if the look. I wanted
to try out a green screen. A green screen allows me to preview backdrops quickly
and get the best look. Try doing this with a muslin. It's very time consuming
and frustrating trying to get the right look and you can't tell if the backdrop
looks good until you're in post-production.
Editing raw footage is the easiest part of working with green screens. The first
thing you need to do is set up your studio space. Green screens can go
horribly wrong if your studio is not set up properly. The green screen should hang
from the ceiling to the floor, preferably against a wall with no windows. Don't
worry about removing wrinkles. I hung mine immediately after unboxing
wrinkles and all. Follow the next few steps and you won't have to worry about
wrinkles at all place an X on the floor about 7 to 8 feet in front of the green
screen. That's where you'll be standing being
this far forward will allow the camera to optimally blur the background your
camera should be anywhere from three to nine feet in front of you depending on
the lens and sensor size I'm using a canon 70d with a 51.2 lens so my camera
needs to be about nine feet in front of me
depending on your lens and camera adjust the distance to get the look that you
need light yourself with a ceiling mounted light set the temperature to
5600 if you can't mount a light from the ceiling use a ring light around the
camera the light should not be more than about four feet in front of you or it
will not be effective set two lights onto the green screen off from the side
they should be back from the screen by about 3 feet diagonally this will
eliminate any shadows cast from the main light set their color temperature to
3300
once we have all the raw footage in Final Cut it's very simple to remove
that green screen background the footage I've laid out here is actually the
footage for this video in the first three clips we don't have a background
so let's go ahead and apply a background and see how that looks I think I'm gonna
have a bit of a problem right here so let's go bring the background in and
I'll just bring it over
now to remove the green screen I need to use an effect so let's go over and open
up the effects section that I'm looking for keying right here so I'm going to go
ahead and take the keyer and bring it down to the first clip so we can see
that the green screen has been completely removed my background image
doesn't completely stretch so we need to use the transformation tool
and we just want to drag it till it fills the entire screen looks pretty
good right about yeah it looks good no no there we go click done
so to fix this issue here that we have in this corner I'm gonna go over to the
keyer I'm gonna use the matte view and with the matte view you can see it's
actually a pretty clean image it's just that lower corner so the way to fix that
choose sample color I'm just going to draw a small little rectangle until it's
gone
perfect looks good okay let's switch back to the composite view that looks
perfect now what I can actually do is I can copy this clip and then do shift
command V and I can actually copy over the transformation as well as the keying
I don't want to copy over the white balance though so there we go fix there
- that looks good this just do a test with the matte yep
looks good and our next clip same thing shift command V and just remove balance
because that's already been fixed now look how perfect that is looks really
really good now the other thing you might want to do here is you might want
to come down to the background because it looks like I'm right there right
close to the background seems a little claustrophobic but I can add a bit of a
depth by using another effect so let's bring that effect over to the background
that's a little bit too blurred out so I'm gonna adjust that a little bit I'm
gonna reduce the amount way down to about there so you can see what it
looked like without it a little bit too sharp and that's giving it a sort of a 9
blurred background so it doesn't look like I'm right there and that's I think
that looks pretty good we still have a little bit of work to do if you look at
the edge around me it looks a little artificial there's still a little bit of
green there so what I want to do is I want to soften it a little bit and I
want to remove that green so under keyer we're gonna go to Matt tools now I've
already set the levels to 0.3 and I like that that really kind of that helps to
soften it a little bit what we really need to do here is use the softener drag
that to about there but let's shrink the Matt a little bit perfect well let's see
the problem if we shrink it too far we're gonna have with holes in the mat
and that won't look good so we don't have any holes good and have we solving
it too much just won't do it just a little bit overdo it and it just doesn't
look natural see so you can see my shirt you see those little black holes that's
because we've shrunk it too far
there that's better so you'll notice now I don't have that green are around me
and it's got a softer edge looks a little more natural grease greens are a
lot of fun to work with they're easy to set up the real expense is in the
lighting and the rigging well it's possible to do green screens with fewer
lights and being and standing closer to the screen itself you might end up with
unwanted results that require additional work in post-production if you have any
