All right, I admit it. Whenever I'm bored working on a project, I usually launch Motion and start messing with the Replicator. The fact that you can replicate anything in your project is pretty amazing and the Replicator is the perfect tool to create complex and beautiful transitions. So, let's play back our project so we can see where we are starting for this transition. And as you can see, I've got a Bezier brushstroke that has a paintbrush effect on it and now we're going to use this as a source for a Replicator and we're going to create a transition.
Notice the comp is only two seconds long. So to get started, go ahead and select the Bezier stroke and then go right up to Replicate at the top of your Tool panel and immediately we have kind of a cool effect here. Everything is repeating in this grid-type fashion. But let's open up the Inspector and see what kind of options we can mess with within the Replicator. First thing I wan to do is change the shape from Rectangle to Spiral.
Now, you notice, we can adjust the radius of the spiral as well as the number of Twists, here we go, and the Number of Arms. So, let's actually leave that at 2. Now if we go ahead and play back our project, you can see we have this kind of really cool 3-dimensional swooping pattern that's going on here, but I want these lines to kind of swoop around and interact with each other. So, let's adjust the angle.
If you go ahead and crank around the angle here, you will notice now I'm getting quite a different effect. So I want this to constantly spin. So, let's go ahead and Control+right- click on the word Angle and just set a rate. The rate just means it's going to constantly be moving by however many degrees you set right here in the Rate setting. Now, if we go ahead and press Play, you can see they are swooping around, but I also have kind of another motion that's happening there.
Now, it's kind of hard to pick out but there's one other setting here that we should be looking at. So, reselect your Replicator and I want you to change the Angle End. If we go ahead and crank that Angle End around here a little bit, now we are starting to get some of that flowering that I was actually looking for. I really think that looks kind of cool. It looks like the inside of a chambered nautilus. So, let's move our playhead back to the beginning and check this out. Oh, my goodness! I think that looks really, really cool.
So, in order to actually have this work as a transition, what I want to do is change the overall scale of everything. So, I will just pause playback here just for a second. With the Replicator selected, let's go down to the Scale option and if we just crank this up to 300, we still get kind of a cool effect. We would play it back to the beginning and press Play. So, I don't think setting one individual setting is going to be quite enough.
I think we are probably going to have to go ahead and keyframe both the start and the end of this Scale effect. So, turn on automatic keyframing and let's move our playhead back to the beginning here and change the Scale back to 100. Now, if we press Play, you can see we've got the lines popping out here. That looks pretty neat. But right around 18 frames let's crank up the Scale to around 300. And just move your playhead down the timeline a little bit more and once we get right around 1 second and 5 frames, let's bring that scale right back down again to around 42.
Now if we turn off automatic keyframing, we can move our playhead back to the beginning and let's make sure we deselect the Replicator so we don't see it in our canvas. I am just going to make things a little bit larger here and let's check out our animation. Wow! I think that looks pretty cool, but just to check out what it would actually look like with some real footage, why don't we go ahead and drop some in? Press F5 to open up your Layers panel and let's close the Light Streak layer and make new layer. So click the plus button and let's position our new layer underneath the Light Streak layer, clicking-and- dragging down to the left.
Now, if we go to the File Browser, in our Exercise folder, under Media, and then Video, we have two video clips. So, let's drop the first one in right here on the lower layer. There we go! Go ahead and scrub your playhead until right around frame 18. Now let's drag the FallsSun render up into that same group layer. Select the FallSun layer in Layers panel and then press I on your keyboard to trim the start point of that layer.
Now, when we roll our playhead back to the beginning, we can go ahead and preview our animation to see exactly how well our transition worked. So, I think it's going to work. Now, it's not giving me the smoothest playback right now. So this'll probably actually play a little bit faster, but all in all I really like the effect. So, when it comes to creating interesting patterns, you can't beat the graphics that you can create using the Replicator. At least you know you'll never be bored.
