Join Ran Ben Avraham for an in-depth discussion in this video Animating the squash and stretch, part of After Effects: Bouncing Animated 3D Sphere.
- [Instructor] Our Sphere's Animation is looking very good.…But, I think we can raise it up a notch.…After all, we haven't created the squash and stretch…automated animation for nothing.…So, let's go back to the beginning of our animation.…And, let's create a key frame…for the squash and stretch slider.…Now, let's hit U, one more time,…to reveal the new key frame.…
Wonderful.…Now, let's move forward, just a little bit.…At about this point, I think the sphere should be stretched.…Actually, let's move forward one more frame…just to make it around 10 frames,…and we'll set the squash and stretch to zero,…which is the stretched pose.…And, we want it to remain squashed…up to this point, I believe,…so we'll copy the last frame and paste it.…
And, in the very last frame, we want it to be squashed,…so we'll change it two, and three frames afterwards,…one, two, three, we want it to be at it's normal pose,…so we'll change it to one.…Let's actually zoom in there a bit.…I think we can have some more space, here.…Something of this sort should do, let's see.…
This is a project-based learning experience. Each step of the process is rich with object lessons that are applicable to the variations that a motion design and compositing artist will face in the real world.
