Today,
we’ll take a look at replacing computer
or phone screens in your video.
We’ll take a look at a few different examples,
including static shots,
moving shots,
and even replacing screens
with movement in front of them.
Hey guys, whats up.
This is Serge,
and welcome back to my channel.
Before we get started,

First up,
we’ll take a look at simple screen replacement
with no movement.
The camera is on a tripod,
and there’s no movement in front of the screen,
so this will be nice and simple.
Also, in my demo clip,
we’re using a green screen,
but for this method it’s not necessary.
Select your screen replacement clip
in the media browser,
and connect it above your timeline.
Next, from the viewer dropdown menu,
select the Distort tool.
Click and drag the four corners
to line up this clip to your screen.
Zoom in on your viewer for more precision,
and make your top clip slightly bigger
than your actual screen.
Next, from the effects browser,
select the Masks category,
and add a Shape Mask to your top clip.
In the inspector,
set the feather amount to zero,
hold down the option key
to adjust the control point individually,
and click and drag each control point
until the red line lines up with your screen edges.
Next, adjust the curvature to match your screen,
and bring set the feather amount to about 10,
to blend your two clips together.
A quick and easy screen replacement.
Our next demo clip
is similar to the first one,
except this time,
the camera isn’t on a tripod,
so theres a bit of motion in this clip.
Once again,
place your replacement clip above your timeline,
move your playhead to the start of the clip,
and use the distort tool
to line it up with your bottom clip.
Make sure your playhead is at the start of your clip,
and add a keyframe to your distort parameters.
Go through your clip,
one frame at a time,
and adjust your distort tool to follow your screen.
Take your time here,
and do it as accurately as possible,
for the most realistic look.
Next, add a shape mask to your top clip,
adjust the size and curvature,
and set the feather amount to around 10.
Your mask will move with the top clip,
so there’s no need to keyframe it.
Your finished result should look like this.
Looks good,
but as you can see,
can be very time consuming.
For our next clip,
we’ll take a look at how to do this much faster,
using a tracking plugin.
The one I use, is Coremelt’s TrackX,
and I’ll leave a link for it in the video description below.
TrackX isn’t free,
but if you need to track anything in your videos,
can be well worth it’s price.
Now, where in the previous clips
it didn’t really matter what was on screen,
this method
requires a little bit of forethought when filming.
To get a good tracking result,
you need to have something on your screen
with consistent detail that can be tracked,
not just plain color or large moving reflections.
I find a solid background
with tracking markers works best for me.
A quick google search for tracking markers
will give you lots of options for this.
So, with TrackX installed,
open your Generators browser,
select the C2 TrackX category,
add the Track layer above your clip
and ripple trim it to the desired length.
Place your playhead at the start of your clip,
choose the polygonal shape tool,
and draw a shape around your tracking markers.
It doesn’t have to be exact,
as long as the selected area
has detail that can be tracked.
Click the first control point to close your shape.
Next, click the track forward button,
and let TrackX analyze and track your clip.
Once the tracking is done,
move to step 2, Surafce,
click on the surface source clip box in the inspector,
choose the clip you want to place inside your tracked area,
and click apply clip.
Next, set the mask blur to about 1,
zoom in on your viewer,
and click and drag the corner controls points
to resize your clip to fit your screen.
This achieves the same thing we did in the last clip,
except much quicker and easier.
Next, let’s take a look at screen replacement
with movement in front of the screen.
There’s two ways of doing this.
One way is adding and keyframing a draw mask,
or an easier way,
is to use a green screen like in my demo clip.
Select your clip,
hold down the option key,
and drag up to make a copy of it.
Press V to disable it for now.
Next, select your replacement clip,
connect it above your timeline,
and use the distort tool
to resize it over your screen.
Press V to re-enable your copied clip,
and drag it up to the top layer.
From the effects browser,
select the Keying category,
and apply the keyer effect to your top clip.
Let your clip render out,
and you’re left with this effect.
And I do apologize
if anyone finds the timing
of my demo clips a little bit offensive.
So, thats a couple different ways
to replace screens in your videos.
