Apple Motion 2 - Manual (Page 446)

The values of your keyframes are not changed.
Auto-Scaling: Auto-Scaling mode continuously stretches the graph to fit all of the
curves currently in view.
To turn on automatic scaling:
m Click the “Auto-scale vertically” button at the right edge of the ruler.
When “Auto-scale vertically” is on, the range of the graph increases to accommodate
your entire curve even as you change it. For example, if you drag a keyframe up to
increase its value, as you drag past the top of the window, the whole graph is rescaled,
rather than scrolled.
This can be disconcerting at first because it might appear that your curve refuses to get
bigger even as you drag your keyframe. However, if you watch the zoom/scroll bar at
the right side of the window, you can see that the graph is being zoomed vertically to
make room for your wider range of values.
Animating On the Fly
Another powerful feature that Motion offers is the ability to create animations while
your project is playing back. This is similar to how audio engineers adjust sliders for
each of their different audio channels while listening to the mix. The next time it is
played back, all of those changes are incorporated.
Since so many of Motion’s effects are displayed in real time, for the first time, you can
perform a sort of “visual mix” and modify the various parameters of your effects while
the project is playing back.
