Take an ease from existing keys
- Select the keys whose easing you want to reuse.
- Click Copy.
- Select your target keys, on one or several properties or layers.
- Click Apply.
Copy changes only Curvy’s held curve. It never changes the source keys, even with Apply as you edit on. It also works when the source selection is entirely on locked layers.
The copied curve describes relative progress. Apply calculates speeds for each target’s values and duration. It keeps key times, key values and spatial path tangents. Roving keys keep roving. Applying a curve switches the affected sides to Bezier interpolation, or Linear for a linear curve, and turns off temporal Auto Bezier on affected keys.
Understand the selected segments
With two or more keys selected on a property, Curvy changes the outgoing side of each selected key and the incoming side of the next selected key. It leaves the incoming side of the first and outgoing side of the last alone.
Select neighboring keys for a complete segment. If your selection skips keys, Curvy changes the selected sides and leaves the unselected keys untouched.
A lone selected key gets both its incoming and outgoing easing. Curvy uses the neighboring segments to work out the speeds. A property with only one key has no travel to measure, so its speeds are zero.
Change one side or flip the application
Use Option and Cmd on Mac. Use Alt and Ctrl on Windows.
| Gesture on Apply | Result |
|---|---|
| Click | Apply both eligible sides. |
| Shift-click | In only changes incoming easing. |
| Option/Alt-click | Out only changes outgoing easing. |
| Cmd/Ctrl-click | Flipped applies the time-and-value reversal without replacing the held curve. |
Hover Apply while holding a modifier to see the side or flipped preview. Shift takes priority over Option/Alt. A one-sided application takes priority over flipping, so use Cmd/Ctrl on its own to flip.
Read the ghosts
Ghosts let you compare the target selection with your held curve. After applying both sides, the old ghosts close onto the applied curve.
A selection with several eases does not become a saved sequence. Copy takes the first readable curve in the order After Effects lists the selected properties, with keys read in time order.
Curvy reads up to 200 selected segments and displays up to six distinct ghosts. For a property with several ease dimensions, Copy reads the first dimension that moves. Apply uses the same curve shape for every dimension. Read a smaller selection or a separated dimension when you need to choose a particular source ease.
Locked layers and hold sides are skipped during application. A mixed selection can still succeed, with the skipped items reported. If everything is skipped, troubleshooting explains the message.
