bjbj [Music Playing] ve already looked at a lot of green screen tips and this time,
we re gonna take a look at some of the more advanced ones when we look at the magic of
flight. First off, we re gonna take a look at how you actually launch and then, we re
gonna take a look at the actual act of flying through the air while using a green screen.
I m Tom Skowronski and this is advanced green screen tricks. The first step is gonna be
to light the green screen and light your subject. You re gonna wanna make sure that your subject
and the props that you re gonna use are gonna stand at least four to six feet away from
the green screen, so, again, the green screen will stay lit evenly and you won t develop
any shadows on the screen so you can pull off a proper effect. Step number two is to
frame up your subject in a manner where you cut off the lower portion of their body. The
reason we re doing this is because we re not in a Hollywood studio and we don t have wires,
so we can t shoot the entire body as a whole or else our illusion will be broken because
we ll realize that the subject is actually standing on their tippy toes, which is not
the best for this type of effect. We want to make it look like they re flying, so we
re gonna have to frame up our subject in a manner where we cut away that portion of their
body so we re note distracted when we re doing our effect. When we do this effect, what we
re gonna do is have our subject bend down and bounce upwards and, in order to pull this
off completely, we need to make sure that we don t actually see the subject not leaving
from the ground, which is why we re cutting off the lower third and the lower portion
of their body. Step number three is gonna come by way of two options we re gonna do
at the same time. We re gonna make sure that our subject is selling the effect in time
with us off camera, bringing the fan down as she goes through her motion. And when this
happens, our effect looks very clean because we made sure to time out the launch with the
wind from the fan hitting her face, which makes it look like she s actually flying through
the air at an alarming rate of speed. Now, the key to pulling off this step is to make
sure that when you re off camera, you bring the fan downwards so that, as the subject
s going up, it looks like she actually is competing with the wind and has some resistance
as she s flying through the air. The final process to pulling off this effect is to go
back into your editing program. In our case, we re gonna be using After Effects, and make
sure that you insert video into the background that s gonna complement what your subject
is doing in front of the camera. In our case, we wanted to make it look very fast. And so,
what we did is put fast clouds that are going downwards as our subject moves up into the
air. Now, in order to actually fly on camera, you need to make sure that you have a nice
prop that you can have somebody lay on. It can be a stool. It can be a bench. It can
be a chair. It could be anything that you could frame out of the shot later on or cover
with a green screen. We only have one green screen, so we re not gonna use it to cover
our prop. We re just gonna frame it out, which is actually step number two. Now, one of the
most important parts of this next step is to make sure that when we frame up our subject,
we cut out our prop or else it s gonna completely destroy the effect. We need to make sure that
our props support our subject and stay stable or else our effect isn t gonna work and this
is why we need to make sure we frame out that prop from the shot because then everybody
s gonna know how we set it up. Now, that we ve framed up our subject correctly, it makes
room for our next step, which is bringing in the fan and putting it directly under our
camera to blow wind into the subject s hair and along their face. This works especially
well if they have loose clothing because we can see it flailing in the wind and it sells
our effect even better. Now, although it s good to make sure that your subject is wearing
loose clothing, you need to make sure you have a fan that s powerful enough so that
if the subject has a necklace hanging or anything that s extremely loose, that has a lot of
weight to it, that it s actually blowing in the wind. If it s not, you need to make sure
that those things are either removed or taped down so that they don t destroy the effect
you re trying to create. Again, as we learned prior, we need to make sure that our subject
sells the effect and make sure that they re reacting to the wind that s blowing in their
direction. If they re flying, they need to act like they re flying. So, the next step
is selling the effect. The last part of this process involves matching the location once
again. So, we need to make sure that if our subject is moving forward in front of the
camera, that the background is actually moving away from the camera. So, this sells the effect
that the person is flying through the air and they re flying in a certain direction.
If we don t do this, our effect will be broken. Even though you don t have a motion picture
or a big budget to work on at home and you may have a limited amount of resources, you
can still apply these tips when creating your own green screen effects. [Music Playing]
