Join Ashley Kennedy for an in-depth discussion in this video Grouping composited clips together as a submaster, part of Editing with Composites and Effects in Avid Media Composer.
In this movie, we're going to put all the AniMatte tools together to composite our spaceship scene, and we're also going to take a look at a very useful tool called the Submaster effect, which will allow us to animate an entire group of layers and effects at once. Let's take a look. Okay, so we have our subject and we have our spaceship and we have our background, but he's facing the wrong way and we need this to move. I'm just going to show you what the master sequence should look like here.
And, here we have him turned around the other way. And he's moving because the spaceship is moving. Okay, so we need to make that happen. But if you take a look--if we wanted to cause movement, we have three things to move. We have the subject. We have the ship. And we have the AniMatte shape. So we would have to go through each layer independently and move them each separately. Or we can actually combine them together, which is what we're going to do.
So what we want to do is nest all of these into one nested sequence, and we're going to do that via a collapse. I'm going to go ahead and just mark an in and an out point on either side of this sequence, and this button right here is your Collapse button. I'm going to go ahead and press it. And now you have everything contained in one layer. If you wanted to see inside of the collapse, you could always step in. And there it all is. I'm going to go ahead and step out.
But now that this is collapsed and we only have one track that we're dealing with, we can actually manipulate all the layers at the same time. If I open up the Effect Editor, you can see that the collapse is now nested underneath something called a Submaster. And, if you ever needed to just do this within the Effect palette, the Submaster is located within the Image category. All right, so you notice there's no parameters to adjust in the Submaster, so we're going to need to auto nest a 3D Warp on top of it.
So we'll go to Blend, and I'm going to Option+Drag, or Alt+Drag on a PC, my 3D Warp on top of my Submaster effect, and here's all of our 3D Warp parameters. So we need to do a couple things. We need to first, put a keyframe at the very beginning and very end. And then I'm going to go ahead and select both keyframes, Command+A or Control+A on a PC, and we want to just rotate it around the Y axis so he's looking the other way.
So go ahead and do that, and oops, too far, going to just press Shift to make it a fine motion like so. And then we actually need to scale it up because we can't introduce any movement because this is perfectly sized. So if we introduce movement, we would have the background showing behind and we don't want that. So let's also scale it up, again with both keyframes selected, and now I'm going to select the first keyframe and start him off over here.
And select the last keyframe and move him to the left. So now he's moving all at once. I think in my final movie, I actually ended up placing him in this window. And you certainly could. We could go inside the Submaster and move him over. You certainly can feel free to do that. But right now, I just wanted to get the concept across that if you have lots of layers, go ahead and nest them all together. And then you can go ahead and apply effects on top of that to produce an animation across many layers and many effects.
