Learn how to extend the exposure of your drawing to see it further down the frames of your timeline, as well as how to insert keyframes and interpolation between keys.
Okay, we're going to start Part 3 of Making the Ball Bounce and one of the things that we're going to do is we're simply going to learn about putting exposure into the art, putting keyframes in and tweening, in this part.
So what does exposure mean?
Exposure is basically... You can notice that I only have one frame exposed and when I go to frame 2, the ball simply disappears. So I need to make this exposure the length of the scene. So I'm going to go back to the last frame of the scene, I'm going to right-click and I'm going to say: Extend Exposure.
And we can see the hotkey is F5.
And now we have the ball being shown for the length of the scene.
Now, when I animate, I like to keep the Timeline closed. You can see that we have a Peg layer here and a Ball layer here. I want to close those up.
Now the next thing I'm going to do is I'm going to just plan out the timing of my scene.
So on frame 1, I'm going to put a keyframe. On frame maybe 15, I'm going to put a keyframe. And on frame 31, I'm going to put a keyframe.
Now what I've done is I've basically just put keyframes on odd numbers. The reason I like to use odd numbers is when I tween it and put the rest of the scene on twos, everything will be on odd numbers on the timeline.
So let's quickly take frame 2. I'm going to drag that down to the bottom of the scene. And we go to frame 3 and we have just three simple positions already added. And the last thing that we're going to do in this Part 3 is tween.
I'm going to highlight all of my frames and I'm going to press this button. If you've done it right, when you go to your playback, the ball will go up and down.
Now right now, it's kind of a stiff bouncing ball but we're going to add timing and squash and stretch in Part 4.
