Adjusting F-Curves

From: Up and Running with CINEMA 4D Lite for After Effects

Video: Adjusting F-Curves

Now as I said earlier, I prefer to work with linear animation in some of 4d light and after effects. And then add curves when I want them. The default in both applications is to have spline interpetation between key frames. But I usually change my project settings to use linear interpolation. Using the key interpolation settings for the project, and then I add curves when I want them, and I'm going to show you how to do that here.

Adjusting F-Curves

Now as I said earlier, I prefer to work with linear animation in some of 4d light and after effects. And then add curves when I want them. The default in both applications is to have spline interpetation between key frames. But I usually change my project settings to use linear interpolation. Using the key interpolation settings for the project, and then I add curves when I want them, and I'm going to show you how to do that here.

And I will in chapter 404.c.d and I have an existing animation in here Where the head is moving side to side using spline based animation. But the, body is moving back and forth using linear interpolation. Now if I want t to add a little bit of softness, to that, maybe not as much as the default would be. Then I can manually add a little curve to my animation. In the F curve mode. So just to recap, we toggle between F curve mode and key mode by hitting space bar, so make sure you're in F curve mode.

You can make sure that you see as much as you can By hitting frame all and it shows us this linear animation. Now, first thing that I can do is select a single keyframe, and change the interpolation type. The default as I have it set up is linear. Normally it would be splaying. And we'll talk about that in a minute. But one other option is to use step. And you'll notice if I click on step it changes it to, what we call in After Effects, toggle hold, where it only moves when it reaches a keyframe.

So if you want very sudden, jerky animation, you can use that step mode to do a toggle hold. I'm going to undo that so we're back to linear And you'll see that it highlights the Linear button again. Or, I can go to Spline. Now, watch what happens. If I click on spline, it only adjusts this side of the curve. Very important to note. In After Effects, it would generally do both the in and out side of the curve. If you want to change both, let's just go back to frame all, we would select both of these keyframes.

So this one and this one, and click on spline, and then we get curves between both. And just like After Effects, I get these handles that I could use to adjust the values on my graph, or the timing on my graph. Now if I hold down the Cmd key, on the Mac, or Ctrl key on Windows, what that allows me to do is just drag the handles in and out without dragging them up and down. And that's handy because it allows me to adjust the curve, without accidentally, pulling the handles down, which would also adjust the value you can see there.

Suggesting the value up in the main window. So handly little shortcut. Hold down command, or control, in windows just to constrain it so that you can go in and tweak those curves without accidentally adjusting the values. Okay and frame all is very very handy to use a lot so H button on the keyboard will allow you to do a quick frame all. Now we can also do easy eases and ease in and ease outs as we can in after effects.

We have easy ease, ease in, and ease out. And those will give us the same kind of eases that we get in aftereffects if we want to we can make a slight adjustment to that. So let's have a look at What a difference that has made to the animation. So a much smoother animation than we had before just by adding a few little curves. Incidentally, there are other buttons in here for things like auto tangents and they also control the attributes of the key frame.

If you select a key frame You can just click on auto tangents, and it will automatically put the auto tangent values on which are also highlighted appear in the attributes. If we switch of auto tangents, you see that you can add your own values for Left time and right time, left value and right value, so that allows you to adjust the timing on either side of a key frame. And various other options as well. You have break tangents. So if we frame all again, so h to frame all, select this one, and if I want to adjust this tangent separately from this tangent, I can come in here and say break tangents.

And that allows me to adjust one, separately from the other, so you can get a lot more control over the timing, get a sudden change there. A more sudden change in direction. Various options for locking tangents, and tangents lengths, and locking time, and locking values. And then we have zero angle tangent and finally zero length tangent. So all these buttons will help you adjust your curves and get exactly the right animation. Give you a lot of control over the timing and the values.

And there are even more options in the F curve menu. We're not going to go through all of these options. There are loads of options available in the timeline in the various different menus, but if you want to find out more about any of them. Use cinema for these excellent online help to find out more. And here you'll see I've brought up help for the timeline, so if you want to go in. And find out more about all the individual elements within the timeline, you can do so here. But you'll find out more as we work through the following tutorials.
