You can import After Effects compositions like any other supported file type by using the File > Import command. You can export an Adobe Premiere Pro project file from After Effects and open it for editing in Adobe Premiere Pro. You can also copy and paste layers and assets between Adobe Premiere Pro and After Effects. Finally, if you have Adobe Production Premium installed, you can create or import After Effects compositions by using Dynamic Link. Dynamic Link allows changes made to a file in either application to appear in both, instantaneously, without a need for rendering.
