Join Ashley Kennedy for an in-depth discussion in this video Keyframing video and audio effects over time, part of Final Cut Pro X 10.2 Essential Training.
- So far in this chapter, we've been exploring how to apply effects to clips in which the change we create is applied for the entire duration of the clip. But sometimes you want the effect to come in gradually, leave abruptly or even both. Fortunately, through key frames, we can change an effect over time in either gradual or abrupt manners. So let's take a look at this. There are a couple of ways that you can work with key frames in Final Cut Pro 10. The first way is simple, but in my opinion a little harder to keep track of.
And the second way is a little more complex but in my opinion easier to keep track of. So let's look at the simple way first. I'll go ahead and select this clip here and open up the effect browser. And I'm going to apply a blur. And I want a radial blur, okay. So we'll apply that to the clip and I'll open up the Inspector. And I think I want kind of a lot of blur, alright. So we have a radial blur going around our spinning chocolate wheel.
(stereotypical Italian music) And I think about right here I want the blur to go away. So I want it to go from full blur to no blur in this amount of time. So we're gonna add key frames. So I'm just going to press my up arrow so I go to the very first frame of this clip. And then I come up to my radial blur and right now I have a couple key frameable parameters. The one that I want to work with is amount. You can see that if I hover over this, it says add a key frame.
So I'm gonna add a key frame right here at the beginning. And then I'm going to go to the place where I want there to be no blur, about right here, and I'm gonna add another key frame. And right now both of these key frames have the same value. But now I'm going to change the value to zero. Alright, so now over time we should be losing our blur. (stereotypical Italian music) Alright, perfect. To go from key frame to key frame, you can click on this little button right here.
Okay so that's the second key frame, this is the first key frame. Keyboard shortcut for that is Option Semicolon and Option Apostrophe, Option Semicolon to go to previous key frame, Option Apostrophe to go to the next one. If I would like the blur to leave the clip more abruptly, I would just need to add the key frame a little bit closer to the beginning. So if I wanted to add a key frame here. Now by the way once you've added a key frame, it sort of activates key frames and you don't have to add one every time, you can just change the parameter.
Okay, so I'll just bring this down to zero. And you can see that this becomes yellow and that means that a key frame has been added. Alright so now I have two key frames that are the same. Right now I have a key frame of zero here and I have one down here and I know that I can navigate from key frame to key frame but I can't really see them in a better way at this time. So I wanna show you how to open this up in the Video Animation tool. If you right-click on the clip and you say Show Video Animation or Control V, this big stack opens up above the clip.
And a lot of these should be pretty familiar to you. We have our transform, our trim, our distort, our compositing, all of which we can absolutely key frame over time and then up here we have our radial blur. Now if I click on this button right here, you can see that we have our three key frames. So here's our starting key frame, here's our ending key frame, and here's the one that we don't need anymore. So if I click on this one and press delete on my keyboard, it goes away. You can also actually move these to the left and to the right.
And then also if I hold down command, I can move them up and down. So this is the space that you work if you need to do anything more intricate than just simply adding key frames and adjusting values. So if I wanted to add another key frame in here, I would just Option Click and I've added another key frame. and I can do all sorts of things within this space. Alright let's add another effect here. I think I want a mask. I'm just gonna type in mask and I want a shape mask.
Okay so we'll go ahead and add that to the clip. And you can see that it gets added as second in line under effects here in the inspector. And also second in line in the Video Animation tool. So let's go ahead and do it with simple key frames in the inspector first and then see how it translates to the Video Animation tool. So I'm gonna press up to go to the beginning of the clip. And I'm gonna just make some basic changes here. I want to make it round and I want it to go all the way down to zero here.
And now I'll add a key frame on radius. So this effect has a whole lot of parameters, all of which are key frameable, but the only one that we're gonna key frame for this effect is radius. So I want it to open up by the time the blur is done, so about right there. So you can actually line up your key frames in this way. And so I'll just click here and now I'll add a key frame here and again I don't actually have to click Add A Key Frame, I could just bring my radius up and it adds a key frame for me.
Alright so you can see here in the Video Animation Tool that we have two key frames and if I play this we should be ratcheting up on our shape mask at the same time that we're de-blurring. (stereotypical Italian music) Alright that's simple enough. Now if we look in radial blur, there are just a couple of different parameters that we can key frame here. And we key framed the amount. If we come down to shape mask, you can see that there are a whole lot of parameters that you can dial into and you can affect each one differently with different timings.
So while we did something fairly simple, you can really get pretty complex with this. Now one last thing, I'm gonna show you down here, we have our opacity controls within the Video Animation tool and the way that you can work this is that if I open this graph, you can see that there's a little knob at the beginning here. So this might remind you of the audio fade knob that we saw in our audio right down here. We are able to fade in our audio. Well, we can do the same thing with our video.
All we have to do, again, is open up the Video Animation tool, that's a simple Control V. So Control V opens that up and then we pop this open and then we can just fade in our clip. Now there's already so much happening at the beginning of this clip that maybe I don't wanna fade it in as well. Since we are coming up with the shape mask and also the blur. But you can also do it at the end. So if I come to the end here and I just do a Control V and I pop this up and we have little knob at the end too and I can fade that out.
So basically it does the same thing as a dissolve but we saw earlier that when you apply dissolve it sometimes also adds a cross fade to the audio, which you then have to fix. So if you don't wanna deal with that, you can just fade in or fade out your clip with your opacity controls here. You can see how that looks. (stereotypical Italian music) Okay. So as you can see adding key frames is a really effective way to add effect animation to your clips allowing them to change over time in exactly the way that you want.
