Join Maxim Jago for an in-depth discussion in this video Use advanced keyframes, part of Media Composer 8.7 Essential Training: 110.
- [Narrator] When working with effects like the 3D picture in picture effect, you have the option to promote your keyframes to advanced keyframes, and these give you much more control over the timing of your animated settings. I'm going to select the second clip here on my Video 3 track. I'm here in a new copy of my sequence called "Advanced Keyframes," and I'm going to go into my Effect Editor, and in the bottom right corner, you can see there's this show/hide keyframe graphs option.
At the moment, all of the keyframes I'm using apply to all of the settings, so if I select a keyframe and make an adjustment anywhere in the Effect Editor, all of the settings I apply are combined into this one keyframe. I can either click this button or just resize the Effect Editor to reveal the Advanced Keyframe Control. Here you can see, if I select a different keyframe in the preview monitor, all of the keyframes are selected here.
By now, you're probably very familiar with these disclosure triangles. We've seen them in the settings, in the Effect Editor, and here we can see them. Let's look at the Position Control for example in each of the keyframe graphs. What we're looking at initially seems pretty simple. We've got an X axis, so it's just a single parameter, and this parameter is going from 100 and down, revealed in this graph, and then back up again. Let's see, if I jump to the next keyframe, you can see it's zero and so on.
Within this graph, if I want to I can click and drag and make changes, and you can see as I drag here, the position of the image is moving, because what I'm doing is changing the parameter. I can also hold the Alt key and just line up and move the keyframe horizontally as well. Without that Alt key, I can only move on the vertical axis. As you can guess, left to right on all of these graphs represents time, and up and down represents whatever the parameter is that you're adjusting, in this case the X position of my clip.
At the moment, these are linear keyframes. I'm just right-clicking here on a keyframe, and it's quite a long menu of options that I have here, and I want to draw your attention to these four right in the middle, Shelf, Linear, Spline, and Bezier. If I change this to a Bezier keyframe, you can see now I get Bezier handles. Let me resize even further, so we can see this more clearly. If I hover at the bottom of the graph, I can click and drag down, and now I'm getting even more detail.
Over on the left, I've got a zoom control, and this doesn't impact the settings of the effect, it just changes the scale that I'm using to see the graph. At the bottom, there's an option to set this height automatically based on what's described here as the curve height, but it's really the highest and lowest settings that you choose. I'm going to click this button, and we get a nice, clear graph. Remember, we're just looking at X position here, although I think looking at the scale, it's tempting to think of it as size.
Now that I have this Bezier keyframe, I can click the handles and change the way this is timed. There we go. A little bit more flattened towards the end. These curves will mean that the effect has a more gradual result, because of course wherever the green line is defines the setting where the computer has to interpolate the results. If I drag through this now, we're getting a similar result, but it eases in at the end, and then rushes off again.
If I want to, I can add a keyframe here, but now I've got a set of additional options. Do I add the keyframe to the active parameter? That's the one I'm working on right now, or to the entire group, and that would add a keyframe to the X and the Y and the Z settings, or Open Groups. That's any group that's been expanded to show the settings, or to All Enabled Groups, which is the ones you can see with the blue color next to the name, or do I want to add a keyframe to all Open Graphs or to every single parameter, which is what we do when we add a keyframe over here in the preview window.
I'm just going to add a keyframe to the active parameter, and let's shift this up. I'm going to right-click and change this to Shelf. Now, you can see very clearly what's happening with these settings. If I drag through ... I can click anywhere here to drag through. This is now going to jump on screen, jump to partway because of the extra keyframe I added, and then jump back and disappear. Let's change this back to Bezier.
You'll notice if I right-click again, I've got a whole bunch of additional useful options, like again I can add a keyframe, I can delete a keyframe, I can add start and end keyframes, which is pretty useful for start and end point for your effects. I can remove redundant keyframes. That's keyframes that happen to already be at the default values for the setting, and so on and so on. Selecting, and copying, and pasting. The adjustment I've made here in the Position Control for X of course, is the kind of adjustment I can make in all of these graphs right away throughout the Effect Editor.
Very quickly, you can end up with what seems to be a pretty complex view, but the principle of working with advanced keyframes is really exactly the same as the principle when working with simple keyframes. Select the keyframe and make an adjustment to apply settings to it. The only difference is that here I'm working with greater granularity. I'm working on an individual setting rather than applying lots of settings in one step. If you want to hide the advanced keyframe graph, you can click the button or just resize the panel.
