Mini Kiwi, creator of such tools for After Effects as the Tickler, posts a new tool designed to work easily with keyframe mirroring and offset. In fact, the new tool is called simply “Mirror and Offset”.
Offset and create a mirrored copy of the selected keyframes across multiple layers.
Mirror and offset as the name suggests, does exactly that. The After Effects tool can easily offset selected keyframes across multiple layers. It can even mirror selected keyframes at the click of a button.
In fact, Mirror and Offset only operates in two modes, allowing you to offset multiple keyframes across multiple layers with a single click, or Create an exact mirrored copy of the selected keyframes across multiple layers.
Some of Mirror and Offset’s functionality can be found in Michael Delaney’s Rift panel. Rift seems to have more granular control over shifting, sequencing, staggering or randomizing layers properties. Rift can work with things like in and out points, keyframes, as well as taking markers into consideration.
If you are looking for that crazy engineering level of control, Rift might be the way to go for you, however, I am not sure Rift has a mirror keyframes feature.
Mirror and Offset offers ease of use and a much cleaner interface. Mirror and Offset for After Effects is intended to be a simple and easy to use tool, offering a simple interface with a few important options.
Mirror and Offset is available through Aescripts + Aeplugins for just under 5 dollars. Check out the Mirror and Offset script for After Effects here for more information.
