The Mask transition has the ability to take you
from one location
to somewhere completely
different sometimes in the blink of an eye.
I did all of these with the new film
or a 9 and if you want to learn
how to do them to stick around I'll show you

and click the notification Bell to be part
of the conversation The Mask transition
is a fairly Advanced effect,
but you can do this in film or with the right footage
and a little patience.
The first thing you need is a piece of footage
that has some object
that moves completely
across the screen from one side all the way to the other
and that stretches from the very top
of the screen to the bottom.
I'm using some stock footage of a forest that has a tree
which will work perfectly I brought
that into filmora and found exactly
where that tree made its move.
Once I found where it began,
I stretch the timeline out as far as it would go.
So I was looking at the footage one frame at a time.
I split the footage right where that tree began exposing
what was on the right of it.
Then I moved one frame at a time split.
The footage at each frame until the tree was out of sight.
If you've done the same with your footage up
in the left-hand Corner,
you'll want to click on Sample colors
and find the stock green color sample
that filmora provides bring
that down onto the track above the other footage
and start it right
at your first splice Point move one frame at a time to the right
and slice it again.
Now, you'll have a single frame of green screen start
by locking your main footage
in place then put your playhead
on the very first screen screen frame
and click on it up in the preview window.
Now you want to drag the green screen layer
from the left over towards the right.
What we're doing here is we're trying to cover anything
that's to the right of the tree line
that Green Layer up with the right side of the tree
and move the playhead forward
to the next frame repeat the same process
and you'll want to do this to each one of your frames
has everything covered to the right of your tree
or whatever you choose
as your masking point now take your last In frame
and stretch it out a little bit to make it a little longer you
now have a mask track.
Let's export that and then
bring it back into filmora find your next piece of footage
that you want to transition into and bring
that down in your timeline.
Put your new mask footage Right
Above It line up your footage
so that the new footage begins just
before the mask transition starts
and then double left-click
on the masked layer up in the left click on video.
And then in the chroma key drop
down activate that function by putting a check mark next to it.
It should default to Green
so you can now dial
in your green screen to allow the track below it to show
through use the offset tolerance Edge thickness
and Edge feather to make
the transition line as smooth as possible.
This was an easy one
because the tree was fairly vertical
and a straight mask line did the trick
in this next one the post
that goes by the train window was a little crooked.
So in a situation
like this we want to slightly tilt the Screen mask
so that it lines up with the angle
of the object then just repeat for each frame just
like we did before with the tree export
that footage bring it back in
and now you'll have a mask track ready to go there as well.
The jet fighter scene was a little more advanced.
I'd found the stock footage of a fighter jet
on a green screen set.
I put it above my footage
of the trees passing by but when I activated the chromakey,
I could see the trees in front of the Jet
and behind the jet I wanted to do a cloud effect
behind the jet.
So I had to add one more step the way I handled
that was to watch the footage of the Jet
and this time I cut the background footage
below it one frame at a time
as the tail of the jet passed through the frame.
I then inserted my green screen track between the jet
and the background footage and cut each frame
on that track to match the background footage slices
frame by frame.
I move the jet across the screen and lined up my green screen
so that everything behind Jet would look green.
This took some patients.
But once that was done,
I turned off the track with the jet in it
and exported the other two tracks to create
my Mast background footage.
I brought that back into filmora.
And now I had a background shot
that was perfectly masked off behind the jet.
Now.
Here's the cool part.
I brought a third track of clouds and put
that as the lowest track.
I put the new Mass background track above that one and then
left that green screen jet at the very top three layers.
I activated the chroma key feature for the top two layers.
Then the jet layer allowed everything around it to show
through the background layer underneath it only allowed
what was masked off from behind the jet to show through
and that gave me the sky and clouds.
I put them all together and voila.
