Hi

Follow this method:

• Open the project you want to copy into
   
• Save the project with a different name ( Save As)
   
• Open the project you want to copy from
   
• When asked if you want to close the project in 1 - click Add new project

You will now have to movies ( timelines)  in one project - depending on which version of MEP you have these will be on two seperate tabs

or as shown in the drop down below

You can now switch between the two timelines copy and pasting the parts you need from one to the other.

When you have finished copy and pasting select the unwanted timeline and  either 

• click the X on the tab of the timeline you want to remove and confirm removal
  
  OR
   
• select File, Manage movies, Remove from project and confirm removal

Save the project.
