Premiere Elements 11 on Window 7 64 bit.
First fact to remember is that Premiere Elements 11 allows you only 25 Timeline menu markers in contrast to Premiere Elements 12/12.1 and 13/13.1 which offer 99.
The Premiere Elements Movie Menu (Disc Menu) comes in a set of Main Menu and Scene Menu with Play All and Scene buttons on the Main Menu and Scene buttons on the Scene Selection page.
One scenario for your Movie Menu - Placement of Timeline menu markers....
Scene Marker at the beginning of the first Movie on the Timeline
Stop Marker at the end of the first Movie
Leave a 5 frames gap
Scene Marker at the beginning of the second Movie on the Timeline
Stop Marker at the end of the second Movie
continue in this pattern until you get to the sixth Movie
Leave a 5 frames gap between the end of fifth Movie and the beginning of the sixth Movie
Scene Marker at the beginning of the sixth Movie
Absolutely NO Stop Marker at the end of the sixth Movie
Make sure to evaluate the Movie Menu customization area Preview to make sure the navigation buttons are working. The Preview quality is typically not the greatest so best use Preview to test the menu navigation buttons.
In this scenario
1. Main Menu - Play All button is meaningless, selecting it will take the view to Movie 1 only with a return to the main menu after Movie 1 playback
Scenes button - will take the viewer to the Scene Selection page where each Movie can be selected. After each scene selection, that scene will play back and
then the viewer is returned to the Main Menu.
If you omit the Stop Markers, the Main Menu Play All will be functional. However, the viewer can select Movie 3 for example but when it finishes its playback the playback of Movie 4 will start, no return to Main Menu until the end of Movie 6.
Please review and consider and then we can discuss the above further in context with your project goal. Any questions, please do not hesitate to ask.
