The graph editor
The graph editor draws a property as a line of value, or rate of change, against time.
The three views
Section titled “The three views”| View | Shows |
|---|---|
| Value graph | The value against time. |
| Speed graph | The rate of change against time. |
| Acceleration graph | How fast the speed changes, in the property’s unit per second squared. |
All three show the same underlying data. Editing one affects the others. Value, Speed and Acceleration at the bottom of the graph editor switch between them.
The scope button at the bottom steps through Selected curves, Layer curves and
Composition curves: the selected properties, every animated property of the selected
layers, or every animated property in the composition. Unselected curves are dashed; click
one to select it, or Shift-click or Ctrl-click to add it.
Edit a curve
Section titled “Edit a curve”- Drag a keyframe to change its value and time.
- Drag a handle to change the curve’s shape.
- Hold
Altas a handle drag begins to move that handle without its partner, or to join two that were apart. - Join handles, on a keyframe’s right-click menu, joins handles that were apart.
- Turn on Break handles at the bottom of the graph editor to move one handle at a time with no key held. It is off each time Lumit starts.
- Select several keyframes to move them together. Dragging a handle on one moves the same handle on each by the same amount.
To change a keyframe to linear, easy ease, or hold, press Linear, Easy ease or
Hold at the bottom of the graph editor. The default shortcut for easy ease is F9.
Easing…, on the value graph only, opens the easing editor. Auto, Clamp and
Free set the selected keyframes’ tangents.
In the easing editor, a click on a shape applies it. Once a shape is saved, the shapes sit
in two tabs, Built in and Yours. Drag the two handles and press Apply for a
shape of your own: Shift snaps a handle, Alt mirrors the other one. The buttons under
the curve are Read from keys, which takes the shape of two selected keyframes,
Reverse, Apply as you shape, Save…, and More for Import easings… and
Export easings…. Right-click the curve to copy it as cubic-bezier() or paste one.
Right-click a keyframe for Linear, Easy ease, Hold, Keyframe speed…, Copy ease, Paste ease, Join handles and Delete key. Paste ease is listed once an ease has been copied.
Edit ▸ Settings ▸ Shortcuts ▸ Dragging changes Alt to Ctrl.
In the acceleration graph each keyframe has an in dot and an out dot. Dragging a dot up or down changes that side’s influence and keeps its speed, as far as the influence can reach. Dragging it sideways moves the keyframe in time.
Retime in the graph editor
Section titled “Retime in the graph editor”A Retime curve opens on the value graph. With Edit ▸ Settings ▸ Timeline ▸ Editing ▸ Retime opens to Speed on, it opens on the speed graph. See Retiming and speed.
