Easily clone and/or reverse selected keyframes across multiple properties or layers in After Effects! No more hoping you can paste multiple keyframes without getting duplicated effects or layers. And on the off-chance it does work, time-reversing those keyframes only to have to retime those keys anyway.

Key Cloner is a pay-what-you-want tool. Thanks for any support you can give.

Key Cloner is a ScriptUI panel that has three simple buttons:

Clone Keyframes

Copies the selected keyframes to the current time, even across multiple properties or layers!

Clone + Reverse

Clones the selected keyframes and mirrors their arrangement, keeping their relative timing!

Reverse Keyframes

Time-Reverse Keyframes, but the right way. Reverses the order of the selected keyframes keeping their relative timing, but does not move them to the current time, leaving them in place.

Headless Scripts

Key Cloner also comes with individual scripts for each of the three functions. These scripts are intended for toolbar launchers like KBar or ft-toolbar. Create a script button and point it to one of the scripts to use Key Cloner without a separate script panel.
