- [E.J.] Welcome to Motion Graphics Weekly, where you up your mo-graph knowledge one week at a time. I'm E.J. Hassenfratz. Let's get our learn on. Character design is one of my favorite things to do in Cinema 4D, but it's always been a pain to animate mouth movement to link up with an audio track. In this quick tip, I'm going to show you how you can easily use an audio track and the sound effector to create a cartoonish lip-sync rig for cartoon mouth animation.
All right, so here is my animation here. And it's just got some eyeballs blinking. And how I have the mouth built is by utilizing just a couple of sweeps. And basically how the lip rig is going to work is you're going to have a bunch of different mouth poses. So right now, I just have a very simple open mouth, and a closed mouth. And the name of the game is to try to morph between these two mouth states.
And how I'm going to do that is by utilizing a cloner object. Now, if I place both of these mouth sweep objects underneath the cloner, you're going to see that basically by default, my cloner is cloning this mouth three times. And it's just iterating because it's set to iterate between each of those clones. So, closed mouth, open mouth, close mouth, open mouth. So what we actually want to do is use a different clone mode, and that is to blend.
And what this allows us to do is blend between the two open and closed mouth states. And if I increase the number here, you can see that it's even adding more blends between the open and closed. So we're going to utilize this setting to our strength. So we only need one mouth. So I'm just going to use a count of one. And then how we're going to blend between these two objects in the cloner is to utilize a sound effector.
I'll go to Sound Effector, make sure it applied to our cloner object, and we can hit Play and nothing's going to happen because we need to, of course, load up a sound. So in the Effector tab, I can load up a soundtrack and here is a little VO of me. The quick brown fox jumps over the lazy dog. The quick brown fox jumps over the lazy dog. And that is the beginning and end of my voiceover career.
But basically you can bring in this lip sync track, or whatever audio track of yourself if you want. You can load this into the Sound Effector here. The quick brown fox jumps over. And you can actually have this manipulate cloner objects. And how you can do that is you need to make one important setting on this, and it's the ability to modify the clone. So we have some clones we need to modify it and have it morph between those two different states.
And actually, we don't want this to be moved in the position at all, because you can see my mouth is just kind of moving up and down. If I leave this on. Over the lazy dog. That's not what we want at all, so I'll uncheck the position. And if I change the modify clone to 100%, watch what happens. The quick brown fox jumps over the lazy dog. What that allows us to do is use that blend mode to be able to blend between those two open and closed mouth states, which is really awesome.
So basically, the amplitude, or the frequency of the audio, is the difference between the closed mouth strength, and basically the open mouth, and it just blends between those two states using that cloner blend mode. The quick brown fox jumps over the lazy dog. And we can even go down and even use the volume of my voice, and we can even change the sampling if you just watch this little amplitude here. The quick brown fox jumps over the lazy dog.
You want a sample wherever there is a big kind of inflection of amplitude here. So you want to sample, maybe right about here. So you get a full range of the closed-mouth and open mouth. Watch if I bring this up more. My mouth here is not going to open as wide as it could. So I can just bring this down. The quick brown fox jumps over the lazy dog. You're going to see a little bit of wavering there, so you kind of want to sample in a way that you're not getting that jitter.
The quick brown fox jumps over the lazy dog. So that's lookin' pretty good. What we can do is adjust this from peak to average, and that could try to smooth out the mouth movement. The quick brown fox jumps over the lazy dog. And you can see that the strength of the mouth being open is not very strong. So I can increase the strength to 200. The quick brown fox jumps over the lazy dog. And it looks like I need to crank that up even more, maybe 500 and see what that does. The quick brown fox jumps over the lazy dog.
And we're losing part of that lazy, so let's try to see what's happening here. Over the lazy dog. So lazy's right about there, and the reason why we're losing it is because most of that frequency, or the amplitude, is not covered by this little sampling box. So if I just increase that, lazy dog. The quick brown fox jumps over the lazy dog. And I think that helps it a little bit more. The quick. Move this down maybe as well. Brown fox jumps over the lazy dog. The quick brown fox jumps over the lazy dog.
And that looks really good. That looks like it's actually talking along with my dumb voice. So I think we've kind of tweaked the settings pretty well here. The quick brown fox jumps over the lazy dog. But you can see by utilizing just a simple cloner set to blend, and a sound effector, and just some simple, professional V.O., we can easily make our little characters in Cinema 4D say anything we say with this simple lip sync workflow.

Q: Why can't I earn a Certificate of Completion for this course?
A: We publish a new tutorial or tutorials for this course on a regular basis. We are unable to offer a Certificate of Completion because it is an ever-evolving course that is not designed to be completed. Check back often for new movies.
