So I planned to film just that last masking transition to show you guys how to do it but once I got
out there and started filming, I decided to make that short little sequence you saw of
a market here in Ho Chi Minh City, Vietnam.
That masking transition is commonly used by Brandon Li in a lot of his films
so let me show you guys had a crate that in the editing room.
Okay, guys.
This is gonna be a tricky one to get down.
It takes quite a bit of minor adjustments to get everything looking right.
But Brandon is an absolute pro doing this, so do not get bummed if yours doesn't turn
out like his.
Just practice as much as you can.
So I have my two clips right here.
It is very important to have both clips moving in the same direction as well as making sure
they are both stable.
The shakier your clips are, the harder it's gonna be to match them up so they look natural.
You're gonna mask the shot that is going to be shown latest in this sequence.
This is the shot you will end with.
I'm not sure why I put good ending here because it's not.
I come out of a bus which plays no role in the sequence, but for the purpose of this
tutorial it'll have to do so.
Go into your effects window by pressing command 5 and find the draw mask effect.
Drag this onto that ending shot and begin masking out the area that your previous shot
will appear to be in.
So for me it is this grate in the side of a bus before you begin masking.
Make sure to press all of your control points as well as your transform points.
This will ensure that all of your changes in your masking points will be saved.
Frame by frame, let me tell you, it is an absolute bummer to mask something, only to
find out that nothing was saved when you go back and look at it.
The trick for curved objects is to press command and click and drag on a mac to bend your line.
After you've messed out the shape, you'll need to press invert mask so the inside will
show the first clip, not the outside, and then click original so you can accurately
adjust your mask in the shot.
Their goal here is to line up the mask with your edge line.
Skip three frames and then adjust.
The reason we skip three frames is because final cut pro automatically adjusts the mask
gradually based on that first point and that 3 frames over point.
It is not always perfect though, so you may need to go back and adjust it a little.
What I did here was use the scale slider and I increased or decreased the percentage in
order to match the outline.
That way I don't change the mask shape, just the size.
However, when I pan the camera right a did change the dimensions of that line, or at
least it appeared to.
So in this case, I did need to adjust those sidelines.
An easy way to do this is hold down shift pressing those points you want and you can
drag all of them wherever you'd like at the same time.
After your mask is lined up well in the shot and doesn't look fidgety, you can move on
to the beginning shot that will fade out.
Well, Brandon does in his films as he scales the previous shot using the transform tool
to make it flow with that oncoming masked shot.
If he didn't do this, it would look like this.
It doesn't look horrendous, but it does not have that same effect.
The way we do this is by pressing the transform tool on that first shot.
We had a key framework.
Our ending shot starts to come over top.
Our goal here is going to be to bring the scale down for the shot to match us pulling
away from the entrance of that oncoming second shot.
I hope that made sense.
Basically, we want to make the first shot smaller since we are pretending to pull back
away from that first shot.
This will automatically be saved because you did press the key frame at the beginning.
It'll take a lot for you to adjust the scale so it looks proportionally natural.
Something Brandon does occasionally that may help you is freeze framing the ending of that
first shot.
So it's static.
This will make it easier for you since your shot will not be moving in contradiction with
that overlapping second shot.
I freeze framed for this clip, but I realized I didn't have to because I wanted to faded
out sooner than that freeze frame anyways.
Once you think you have made the shot and the mask look natural enough, you'll move
on to fading it out.
That first shot and pressed the inspector window.
Then go to the opacity slider press the key frame at the point in the shot where you would
like to start the fade and find the point in the shell where you would like it to fade
out.
I wasn't happy with the gradual fade, meaning where I pressed the beginning point and the
end point and led final cut pro faded out itself.
So I adjusted the opacity at different increments in those frames.
Just find what you think looks best.
After that, you'll copy the top clip and place it below that first clip.
So your timeline kind of looks like an Oreo and you'll go into that copied clip and delete
the mask effect.
And there you have it, folks.
