The Copy Option Variations using Copy with changes in animation/assets When to Use Copy? So, why would you use one option over the other? Let's take a closer look. It is particularly useful when you want to create variations of animation or effect, create a template, or transfer keyframes or expressions between projects. Copy with Relative Property Links: Creates duplicate animations or effects while maintaining the link to the original property.This option creates a dynamic link for the layer properties such that change in one layer will also reflect in another. C opy with Property Links: Creates a duplicate of the selected asset or layer, and any changes made to the original will also be reflected in the duplicated layers.Any changes made to the duplicate will not affect the original. Copy: Creates a duplicate of the selected asset, completely independent of the original.Let us first define what each of the options does. While all three options creating duplicates of the original asset, there are important differences between them worth exploring. While there are mainly two options for duplicating layers or assets: Copy and Copy with Property Links, there is also another copy option that plays a more dynamic role for a project as a whole, i.e., Copy with Relative Property Links. One of the most exciting things about After Effects is the feature to copy the layer's property and paste it into other layers, with changes made to the duplicate layer also affecting the original.
