Nicolas Dufresne, creator of the amazing DUIK character and animation tools for After Effects, recently updated the DuCop tool. DupCop allows you to manage the parameters of several compositions all at once within After Effects.

Ducop allows you to manage the parameters of several comps at once, now able to auto-adjust layer durations

The new update allows you to auto-adjust the layer durations for multiple compositions as well.

The tool works by allowing you to define the same parameters for multiple compositions in one click– Rather than going through each composition CDWNH98W4AA_-Bmindividually.

This can include tasks such as changing composition resolution, duration, or motion blur settings. The new addition to DuCop, will now let you edit composition duration in much the same way.

When you intend to change composition durations, Ducop can automatically adjust them, as if their duration was the entire length of the parent comp.

DuCop has a checkbox to the parameters for all the selected comps, as well as the pre comps that are contained in them.
