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.
Compatibility: After Effects CC (12.2)+*
*Untested with earlier versions
Key Cloner is a ScriptUI panel that has three simple buttons:
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!
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.
