Apply says No comp

Make a composition active in After Effects, then select its keys. Curvy needs an active composition to read or apply easing. Merely opening a project is not enough.

Apply says No keys

The message Select keys to ease means Curvy found no selected keys it could target. Select the keyframe diamonds on a property in the active composition. A layer selection alone is not enough.

For Copy, the corresponding message is Select keys to copy from. A selection containing only unreadable hold segments can produce this message too. A refused copy keeps the held curve.

Apply says Locked

That layer is locked or Those layers are locked means every target is locked. Unlock the layers you intend to edit.

In a mixed selection, Curvy applies to unlocked layers and reports the locked layers it skipped. Copy can read locked sources when no unlocked sources are in the selection.

Apply says Hold keys

That key holds, so it can’t ease or Those keys hold, so they can’t ease means there were no eligible sides left to change. Curvy preserves hold interpolation. It also leaves a segment’s side alone when the selected key at the other end holds.

Change the intended hold sides to Linear or Bezier in After Effects, then apply again. In a mixed selection, eligible sides still receive the curve and skipped holds are reported.

Properties that cannot accept Bezier interpolation are skipped too. They can be included in the hold-skip feedback. Those keys can’t take an ease, with a No ease badge where there is room, means no compatible key sides could be changed.

My curve changes the keys before I click Apply

Apply as you edit is on by default. Turn it off in settings to prepare curves without changing the current selection.

If editing seems to do nothing to the timeline, check the same setting and your key selection. With no keys selected, Curvy only edits its held curve. Quiet automatic applications may show a short refusal badge without a toast. Click Apply for the full message.

Position does not overshoot like the card

Unseparated Position receives a curve constrained to its spatial travel. Use the Separate offer if you want individual coordinates to overshoot. Read Overshoot Position before separating a curved path.

Copy does not match every selected ease

Curvy holds one curve. It reads the first available curve, with up to six ghosts for comparison. It does not copy a sequence of several curves or a separate curve for every dimension. Select the specific segment or separated dimension you want to copy.

The numbers field stays open

Invalid input nudges the field and leaves the existing curve alone. Check the accepted formats and ranges. Press Enter to submit or Escape to cancel.

That curve is broken, with a Broken badge where there is room, means the requested curve is invalid. Enter a valid curve or take a built-in classic and try again.

My library file will not import or export

MessageCause and fix

That file isn’t a Curvy libraryThe JSON is invalid or uses another format. Use a file exported by Curvy.
Those curves are already hereNo entries were added. They may already exist, be invalid, or the library may be full. Check your favorites and the 48-curve limit.

Import adds to your favorites. It does not replace them. See Save and share favorites for the merge behavior.

Copy as CSS says The clipboard said no

The clipboard write failed. Try Copy as CSS again. The held curve remains available in Curvy.

Curvy could not read or ease the keys

Curvy could not read the keys, Curvy could not ease the keys or Curvy could not finish means the request did not complete normally. Make sure After Effects is responsive and a composition is active, then select a simple pair of keys and try again. These messages do not identify a specific selection problem.

Controls or favorites disappeared after resizing

Curvy reduces labels, feedback and shelf space in small slots. The full library stays available through the book icon or the card’s Library… menu. Use Type numbers… when the readout does not fit. Controls and slot sizes shows the layouts.
