The real-time engine in Motion 3, a component of Apple's Final Cut Studio 2, gives motion graphics designers the freedom to continually experiment and adjust while they work. Ian Robinson explores how to get the most from this unique application, while also sharing his own essential motion graphics techniques. Along with teaching the fundamentals of video and audio work, he looks at Motion 3's new 3D tools in depth. Ian demonstrates the use of behaviors to create organic movement in particle systems and camera moves without keyframes. He also discusses effective integration with the other Final Cut Studio applications, and much more. Example files accompany the course.
Animating Replicators in Motion is very straight forward, hit F5 to open your Layers pane and select your Replicator. Go and hit F5 again to close that and choose Add Behavior, Replicator and Sequence Replicator. Open your Inspector and on the Behaviors you should see the Sequence Replicator behavior, the first thing it's doing is asking what Perimeter would we like to Add to animate. So click on the Add menu and choose Rotation.
What we are going to do is actually rotate these diamonds 180 degrees all the way through the replicated patterns. So go ahead and click and choose 180 and the first option is Sequence To, I would like you to sequence to 180 degrees. Under the Unit Size for now we will choose Object, go ahead and hit the spacebar and see what this is doing. Now it's starting from the center point for a reason, stop your playback, move your playhead back to the beginning and look at the Replicator.
Right now the Origin is set to the Center, if you choose Upper Left and hit your spacebar; now you notice its starting in the upper left and spreading out through the rest of the Replicator. Stop your playback, let me change this back to Center; go back to your Behavior, lets look at some of these other options, click on the Object pull down and this time choose All, hit your spacebar and as you can see its replicating all of the diamonds in the Replicator.
Stop playback change it to Custom, if you notice under Custom you can change according to percentage how much of the Replicator will rotate. Hit your spacebar and right now it's just 10%; let's slide the end slider up to 50 or 51. Stop your playback; I want to change that back to the Object size. The Spread is how many objects will be rotating at any given time so right now the Spread is 1 so before the next object rotates the previous object has to finish.
So if you hit your spacebar you can see 1, 2, 3, 4, 5. It's just rotating through each individual object. So if you increase the Spread you will notice now more of the objects are changing, just increase it to something like 8 that way you can see it a little bit more clearly. Stop your playback and change the Spread back to 1 and adjust the Traversal; what this is, is how the object is completing its task.
Since we are doing Rotation right now, it's completing the rotation at one constant speed; if we choose Ease In/Out, hit your spacebar and you can see what I am talking about, it's just easing into the rotation and then back out again. Stop your playback and if you choose Accelerate, hit your playback again and you can see it accelerates through the rotation slowly getting faster. Stop your playback one last time and go back up here.
We will choose Constant Speed and adjust the Loops. This is how many loops it's going to complete before the end of the Sequence Replicator behavior. Now since my Behavior is set to go through the entire length of the composition, this will be how many times it completes a loop before the end of the composition. So go ahead and crank that up to 5 and hit your spacebar and you will notice the sequence is happening a lot faster because it has to complete this 5 times before the end. If we change our End Condition to Wrap, it will complete the task and then start again right from the beginning; if you change this to Ping Pong, once it gets to the end it will bounce back and head back the opposite direction.
Go ahead and stop your playback and that's the basics of animating Replicators.
