How to transfer Keyframes from one AE file to another

[Stefan Cargoski]

Hi forum.

I have a file with multiple keyframes (around 30) on a layer controlling the opactiy of the animation. I dont want to redo the same opacity values on the new AE file one by one, what is my best option? 

Thank you.

Import the AE file into the current project, open the composition that contains the layer with the keyframes, then copy the keyframes from that layer to the other layer in your current composition where you want to use them. Finally, delete the project you imported if you no longer need it. 

one more way, copy the keyframes from the layers in project 1, then close the project.
open the other project and paste the keyframes on the selected layer.
