So far in this chapter, we have been exploring how to apply effects to clips in which the change we create is applied for the entire duration of the clip. Sometimes, however, you want to make an effect come in gradually, or leave abruptly, or even both. Fortunately through keyframes, we can change an effect over time in either gradual or abrupt manners. Let's take a look. All right, so I'm going into 9.6, and let's open up the Effect browser. And let's say that we want our first shot here to come in with sort of an aged antiquated look and then just slowly come into full color the way it is right here.
So, what I am going to do is apply Aged Paper and Aged Film to this shot. Let's open the Inspector, Cmd+4, and if we want to make any Global adjustments, I am going to do that now. So, I think it's a little much, so I'm going to sort of bring it down, like so. and bring back the Aged Film a little bit. Okay, so this is kind of what it's going to look like when the shot opens. But of course we need to dial it down as the shot progresses so that we come to full color.
So what I am going to do is park at the very beginning, and we first have to set a keyframe to store these full on values. So, what I am going to is come up to Aged Paper, and I'm going to select keyframe, Add a keyframe, so this is the keyframe that's going to store the full value, and I'm going to press it here, and here, and here. So one keyframe isn't going to do us any good, we need multiple keyframes to actually produce a change over time.
So about right here, I am going to set my next set of keyframes like that. I think what we'll do is get rid of it completely, and take away all the amount and then right here, take it away as well. So, we should be progressing from our Aged Paper, Aged Film look, slowly to our full-color shot. Okay. It works really well. In this case, we only added two keyframes, one at the beginning and one halfway through.
But you can add as many as you want. You can have this effect going full strength and then back to 0 and then halfway, many times throughout the duration of the effect. It's totally up to you. If you do have a more intricate keyframe animation or if you'd like to see how multiple effects are interacting with one another, you will probably want to show it here in the timeline. The way you do that is you just click on the clip and then right-click and choose Show Video Animation. Notice that Show Audio Animation is also available, so if you wanted to keyframe your audio effects, you certainly could.
Keyboard shortcut here is Ctrl+V, so I am just going to select that, and let's take a look at what we have got here. Now, as you can see, we have an entire stack of keyframeable effects, and you'll recognize most of them. We have our Trim, our Transform. We haven't talked about color yet, but you can see you can keyframe color. But here are our two effects at the top, Aged Paper and Aged Film. Notice that each one of these effects has a blue light over here to enable and disable it. So, as I do this in the stack here, also notice that it is performed here in the Inspector.
Also notice that if I change the order of the effects in the Inspector, the order is likewise changed here. So I am going to move that back actually because I want the paper processes first. And we can see the various keyframes here in this view. Now, depending on the effect, there may be a dropdown menu where you can choose which parameter within this effects you want to change. So right now we're affecting Mask Size, we can also affect Amount. Some of them like, Mask Size, allow you to open it up even further into this graphical view where we can take a look at our keyframes and then drag them up and down accordingly.
If this Graphical View is not available, then you just have to click on this keyframe and then come up to the Inspector and adjust your amounts, like so. So that's how that works. Sometimes, you get to do it here in the timeline, and sometimes you need to interact between the timeline, and the Inspector. So let's actually take a look and see how this is looking. We have got the general effect going. But I think with Mask Size let's go ahead and do a little something here.
Let's start with this all the way down to 0. And then right here let's go ahead and add a keyframe and make it come up abruptly. So what I am going to do is I can either just drag this up, like so, and you can see that a keyframe was added for me. Let me undo that, Cmd+Z. Notice that I can also hold down Opt, and as you can see, I have the indication that I can add a keyframe with that little diamond to the right of the cursor. And I am going to click, and I add a keyframe, and I can just drag up, like so.
So now this is how it's opening up. Okay, so we kind of have this vignette coming up, and then we gradually have everything else coming on. Okay, so I think that's looking good. Also, one last thing, we again have these little knobs here, and we have seen these before in audio, but they also work in video. Let me just come down to Opacity so that I can show you how this works. Let's go ahead and open up my graph, and here's my little knob.
If I just drag this over like this, this is going to be a ramp of coming up from totally black to full opacity. So it's just a way to quickly fade your clips up and down. And then to close your stack, you just click on this X and the Video Animation tool has gone. But all the work that we did in there is retained. So, as you can see, adding keyframes is an effective way to intimate your effects, allowing them to change over time in exactly the way that you want.
