Join Maxim Jago for an in-depth discussion in this video Keyframe segment effects, part of Media Composer 8.7 Essential Training: 101.
- [Instructor] So far we've looked at keyframing audio level, and it's pretty straightforward, you add a keyframe mark to the clip, and you adjust the height and your volume level is changed over time, it's very straightforward. In fact, keyframing visual effects is only very slightly more complex, and as long as you understand the concept of having an icon, a little marker that represents a keyframe, which has specific settings, then you'll be absolutely fine adjusting those settings for visuals.
I'd like to make a bit more use of this clip. We previously zoomed into the shot using the resize effect, and the reality is that the lady we've cropped out of the shot by zooming in, or resizing, doesn't look at the camera the whole way through, so we can probably keyframe our resize effect to bring her back in and introduce some motion to the shot. Just for comparison I'm going to position my playhead over this clip, and I'm going to press our keyboard shortcut for match frame to find the original master clip in the source monitor.
And if I drag through here we can see, not so far after, she looks away and is no longer distracting in the shot. So, let's see if we can bring her back in. The first thing we're going to need to do is work out our timing. I've got my V1 track selected and the effect is on the clip, so I'm going to go into my Effect mode, and I'm just going to scrub through a little bit here, and if I recall it's pretty much as this gentleman puts his hand out, and onto the shoulder of our subject.
But I can't really see exactly, because, well I'm going to have to go back and forth with the source monitor, and there's quite a lot of clicking. So one way to find out what's going on, is to remove the effect, see I have a button here, because now, with the effect editor open, we're in the effect preview monitor, I can clear this out, and I can drag through, find the moment, and Undo, I'm pressing Control + Z, or Command + Z to bring back the effect. I suppose another option would be to gang these monitors together, as we did previously, with the multiple popup source monitors, but there's another way.
When you apply an effect to a clip in Media Composer, conceptually, the effect contains the clip. In fact, broadly speaking, I'd encourage you to think of the way clips and effects work, along the lines of things being inside of things, containers. Think of Russian dolls where one doll is inside another, inside another, and so on. Later, we'll be working with more complex layered effects, and it's helpful to understand effects in terms of containers, rather than for comparison to think of them in terms of layers, particularly when working with Media Composer.
So one way for me to identify exactly the frame I want, to bring this lady back into the shot, is to step inside of, to get inside of this effect, and see the unmodified original video clip, without modifying the effect. And I can do that by stepping in to the effect. And that's these two buttons down here at the bottom of the timeline, Step In, and Step Out. With my playhead lined up over the clip, and with the video one track turned on, so I'm telling Media Composer which track I want to step into.
I'm going to click the Step In button, and now we're looking at a special timeline, where we only have the contents of the effect, remember the effect is treated as a container. And in this special timeline, of course we don't have a resize effect, because we're now inside that effect. What we have is our original media. In this view, it's pretty easy to see what's going on. So I can scrub back, and there's the glance, and I would say we're in about there even, we can probably get away with it.
Now, I can step back out, and I know that we're lined up on the correct frame, so this is the moment I should add a keyframe, and I'm going to go back into my Effect Editor, and I'm going to click to Add A Keyframe. This point is the last frame that we need her to be zoomed out, so from this point onwards, we can begin to return to the regular-sized shot. I'm going to click forward a little way, maybe about half way, and I'm going to add a keyframe, and with this keyframe active, notice that it's pink, not the other one.
I'm going to go back to my Scaling, I'll set this to Fixed Aspect, and I'm going to click to set it to 100%, there we go. Of course we've got a problem, because our position is off as well. Remember we changed this earlier on. I need to reset this to zero. Coincidentally, when you're in the Effect Editor, if you select a control, with the control selected, you can type a number to apply it, in this case I want zero, so I'm going to press Zero.
If I wanted to scale up to 120%, I can click on the Control and type in 120, and use the Tab key to move on away from that control. Of course, we don't want to do that now, so I'll just Undo. So what we've done is created a keyframe at the last moment that we need to be zoomed in, and then we've created another keyframe at the point in time, where we'd like the zoom out to finish. When we created the first keyframe, whatever the settings were in the Effect Editor, will be stored on that keyframe.
And now with the second keyframe active, we've made changes so Media Composer can create an animation between the two, I'm just dragging through here. Now, if we wanted to put a little more time into it, we could probably get a couple of extra frames out here, because by the time the camera pulls out, she's already turning her head away. So we could play with this a little bit more to get a little more eat out of the shot. But I think as it is now, it works pretty well, let's take a look at this in context.
Not bad. I think the move is a little bit fast, so I'm going to go back into the Effect Editor, and the Effect mode. And now, I'm just going to hold down the Alt key, and Click and Drag to bring this keyframe later. Of course by separating them further, we're telling Media Composer to take longer to apply the change to the effect. Still looks okay to me. We're not seeing her looking at the camera. Let's play this back.
Much better. And as you saw me do there, I wanted to move this keyframe in time, and of course I couldn't because the rule about holding the Alt key down to move keyframes in time, applies in the preview monitor, just as it does on the timeline. And we saw that when we were working with keyframes on our audio. Just like the audio keyframes, if you want to remove a keyframe, make sure it's active, and you can see that because it has the color, rather than the gray. And now you can press Delete, and it's gone.
Keyframes retain their settings, so if I go back to this keyframe you can see we've got our scaling up to 129 and so on. I'm just going to Undo to bring that back so you can take a look at it later if you're working with these media files. And what we're doing here is referred to as Simple Keyframing. So, one keyframe contains all of the settings in it. When we get onto more advanced keyframing, you'll see that it's possible to add a separate keyframe for each individual control in the Effect Editor.
In many cases, you don't really need that much control. But of course it is possible that you'll want to do things like adjust the position and the scaling separately with different timings. The controls I've just shown you to add a keyframe, make adjustments, and add another keyframe, and so on, apply almost universally to the visual effects in Media Composer, and I think the resize effect is a good first case example to get to grips with these controls. Once you understand how these simple keyframes work for one effect, you're ready to try them on almost every other effect.
As usual, I'm going to come back out of the Effect mode, just by clicking here to go into the Source Record mode.
