You can add DVD chapter markers to any sequence in Adobe Premiere Pro that will be read as chapter points when you export that sequence to Encore. In Encore, you can link chapter points to buttons in menus, or viewers can use the chapter advance buttons on their DVD remote controls to navigate through them.
You can name Encore markers as you place them. The name you enter in Adobe Premiere Pro appears as the label for a button in the main menu or scenes menu in Adobe Encore.
