When you link to a new composition from Adobe Premiere Pro or Encore, After Effects starts and creates a new project and composition with the dimensions, pixel aspect ratio, frame rate, and audio sample rate of your Adobe Premiere Pro or Encore project. (If After Effects is already running, it creates a new composition in the current project.) The new composition name is based on the Adobe Premiere Pro or Encore project name, followed by “Linked Comp [x].”
