this video is brought to you by story
blogs video hey folks dirty here for
cine combat nets and welcome to creative
Tuesday as filmmakers we can't always
find the right locations maybe you need
a specific building in the background or
endless open landscape but you also have
problems finding the right location let
me know in the comments below maybe a
next video idea would be about location
scouting anyways either you shoot a doll
on a green screen but that doesn't
always look so good or you simply change
the backgrounds to your needs and this
technique is called set extension and
it's used in almost every big production
creating a set extension is not that
hard but it does come with some
complications which we'll get into but
let's start with the basic principle of
a set extension first place your camera
on a tripod and film ake landscape then
in post-production and this even works
inside Premiere Pro you take a clip that
has an interesting element place it on
top of your shot
head over to the effects controls and
under rapacity victim mask tool to cut
out that interesting element and better
your mask a bunch and align it so that
it matches with your backgrounds if
there's a color difference then just
simply use lumetri to color correct bats
and you can keep doing this you can keep
adding stock clips of various things as
long as their perspective kind of
matches with your shots now we get all
of our stock clips from story blogs
video they're not just our sponsor but
we also make use of their library on
almost every project it's a very big
library packed with stunning 4k stock
clips and it keeps growing every day
you really love it as we can just simply
download a little bit of video assets
without additional costs and this means
we can try out a bunch of clips and if
it doesn't work we can just go back and
download a few more I can highly
recommend it and you can check it out by
clicking the first link in the
description below so now that we know
how a set extension works let's add a
talent in there we still want to change
the backgrounds but the talent sits in
the way the one way to fix that is by
omitting character talents doesn't come
in front of the area that you would like
to add new elements into if you do
decide to change the whole backgrounds
then you're gonna have to mask out your
subjects now you could go Fredro
discover
technique and after-effects but honestly
I've never gotten good results from
gnats so I would really encourage here
to use a green screen this is a portable
one that I can highly recommend it's
pretty cheap and so you can take it with
you everywhere the positive thing about
pulling green Keys on location is that
your colors and lining will always match
so what you do is choose your talent in
front of that green screen and then move
out of the frame and stake an empty shot
of your backgrounds going back into
Premiere Pro that background shot can go
into the bottom and the green screen
shot on top use the mask tool again to
draw on the inside of the green screen
next look for the ultra key effect and
drag that over to the shots this allows
you to select and to remove the green
but since you have your subject on a
separate layer now you could place your
stock clips on top of your backgrounds
but underneath your subjects now one
thing that you might be missing now is
camera movement since we tried
everything from a tripod this was
necessary so that your different layers
will match what we could do is add fake
camera motion in there and we actually
have our own preset back with eight
different handheld's motions which you
can download for free from a link in
your description simply add one of them
to an adjustment layer that lays over
your entire shots and that's it if you
do would like to adds real motion and
you're going to have to work with a
motion control slider or robot arm now
we don't have a robot arm but we do have
some motion control sliders and we've
got one from ito latrone and one from
syrup we did a video for both of them
which are leave a link to in description
below now we are going to use the syrup
slider as it's more suited for heavier
cameras basically I can program it to
make one specific movements take my
shots with a green screen step out of
the frame and make that exact same shot
again in post-production we pulled the
green key and sync the camera movements
and you'll notice now that it matches
perfectly
adding the background elements in there
is going to give a problem since they
need to follow the movement as well if
we would have set the slider at a
constant linear speed you would be able
to simply animate the position of those
elements and make them follow when
there's a larger movement switch panning
and tilting you're going to need to
motion track this and this can be done
inside Adobe After Effects Premiere Pro
does not have a tracking option
unfortunately now I would go for the 3d
camera track
we've covered various times on the
channel when the analyzing is done
you'll get a bunch of points right click
and choose create snow ants camera then
at your element and there make it 3d and
copy the transform values of vanilla
objects and paste it to the element so
that it sits on that same location
finally set the opacity back to 100 and
that's it
of course when you have no talent in the
foreground you could go completely
handheld and it's just really cool as a
POV shot first let your talent walk into
the scene and then show what she is
seeing you don't need to green P you can
just jump directly into the 3d tracking
and adding your elements in there color
correction is one way to make your
objects match better together keep in
mind that elements in the background are
usually out of focus you can use these
sharpness tool for elementary for dads
just simply decrease the sharpness now
you still have trouble matching
everything a simple trick is to add an
overlay effects and I'm talking here
about Sun flares or weather effects and
this you can also find on story vlogs
video if you do like to keep it free
then check out video texels which is a
free stock websites but of course the
quality and offer is not the same but it
does help to get you started so right
here I've got a Sun flare place that on
top of your entire edit and go to
opacity and change the blending mode to
screen or ads and this will kind of
cover up any mistakes and nuts draw too
much attention to it and that's how you
can make any backgrounds that you like
thank you so much for watching thank you
story blocks for the supports and as
always stay creative hey guys this
Friday I'll be going back to Iceland and
I'll be doing some landscape photography
so that's why I have to pack my gear if
you would like to follow me too make
sure to follow me on Instagram where
I'll be posting daily tips and tricks
and how to do landscape photography
through my stories and also post a daily
photo from that beautiful place of
course
