Narrator: In this lesson,
I wanna show you how you can adjust effects
with the key frames.
So this will allow you to create
an effect transition onto or off of a clip.
So here's this shot that I have of the Swiss Alps
that I shot while I was on a trip
to Switzerland with my wife,
and say we want this shot,
maybe this is the end of our film,
or the beginning,
and it's going to start off on the shot,
and then we want it to blur so that we
can add a title over it.
Let's go down to our blur sharpen effects.
We're going to add the Gaussian blur to our clip.
When I do that, nothing happens.
Wee have to go to effects controls,
and first we're going to set
a key frame for blurriness at zero.
So I'm gonna go to where I want it to transition,
maybe right around four seconds,
set that key frame by clicking this stopwatch icon,
then go maybe a second or two later,
and now I increase the blurriness.
Something like so,
and with this effect,
I'm going to repeat edge pixels.
You see here that as I increase the blurriness,
the edge gets a little bit dark.
I don't want that to happen,
so I'm just going to click this repeat edge pixels,
and that makes the edge not have that shadow on it.
So now if I play through this,
it transitions into this blur.
This is something that you can do to,
sort of replicate a blur of focus
if you were doing it manually out there in the field.
Sometimes that works better than others for different shots,
and now with the blurred out background,
we can actually add some text to this
so it will appear a little bit better.
Let me just show you that really quickly.
So if I go to my project tab,
click the new item button,
click new title, just gonna leave it at title one.
Then if I just add this title in the middle,
we'll just call this "The Alps".
Exclamation point. So exciting.
I'm gonna change this to Helvetica.
Change it to bold.
Then use the centre options right here to centre this text.
Maybe add just a little bit of an outer stroke,
just a black outer stroke,
clicking the add stroke button.
Increase the stroke size.
Exit out of that.
Add this to my clip.
Lemme just show it to you what happens.
So here, before it's blurred out,
yeah it's visible,
but right here, when it does blur out,
it's much more visible.
So with this kind of transition,
I would probably create a fade on for the title
as the blur of the background starts to come on.
On the timeline up here,
I'll go to this first key frame,
and I can get to it by clicking this button right here,
these buttons are the go to next key frame button,
and I'll make sure that on my timeline down here,
my cross dissolve starts at that point.
And then I'll go back to this timeline,
go to the next key frame,
which automatically jumps my timeline indicator
down here to this point,
and I'll increase the cross dissolve to that point.
So both the cross dissolve and the blur happen
at the same time, at the same rate,
and that looks pretty darn cool.
So that's how you can use key frames
to adjust the settings of an effect
and create that animated effect on or off of your clip,
or just more or less dramatic.
So maybe it's already blurred,
and then we wanna make it even more blurry,
we can do that.
Let's just set a key frame here again for 49.
Because if I just went here and increased it to whatever,
194, then that means that this key frame to this key frame,
there will be an effect or an animation,
but I want it to stay at 49 for awhile.
So set a key frame there for 49,
and then go forward,
change this to whatever, 200 or so,
drag this key frame to the end of the clip,
and maybe that would be a good place
to fade out of the title.
So let's just fade out of the title here.
Make it a little bit sooner.
Kind of a cool effect.
Anyways, I think you get the point now
how to add key frames to your effects.
Have fun with it and we'll see you in another lesson.
