I'm not sure, but wouldn't it be easier to load the second export into the project? I'm new to Elements but with the organizer, bringing to separate video files together in one project is my best option...
that would just require you exporting it to your PC then loading it into the new project
Carlton is right. There is no way within the program to copy and paste between projects. (There is third-party software that will allow it though.)
The best way to add the timeline from one project to another is to output using Share/Personal Computer/DV-AVI.
Assuming your second project is set up for standard DV, the AVI should load into it with no loss of quality!
Thanks I will try this.
