Figure 8.4 - Object for animation

The animation will have 1.5 seconds using 30 FPS, which means we

need 45 frames. Here is the animation breakdown:

Frame 1: Object will have a scale factor of 1

Frame 22: Object will have a scale factor of 1.5

Frame 45: Object will have a scale factor of 1

Select the object and add a scale keyframe for frames 1, 22, and 45.

Since you didn't apply any scale transformation, all keyframes share a

scale factor of 1. As an alternative, you can use a SHIFT+D after

inserting the first keyframe at the Timeline Editor.

Go to frame 22 and apply a scale to the object with a factor of 1.5 by:

1. Pressing the S key

2. Type 1.5

3. Press RETURN to confirm

4. Press I, and add a Scale keyframe to update animation data with

the new scale value

Part of the trick of using animation loops is that you should skip the last

frame. At the animation settings, make the Start and End frames as 1

and 44. Why not 45 for the End frame?

The reason to use 44 is simple: you want to avoid having two

consecutive frames using a scale factor of 1. If you use frame 45 as the

End, you will have frame 45, and 1 played in sequence. It will create a

brief stop for your animation and break the fluidness of motion.
