It is only the second time that I am using program Motion 5 and I only see the first small screen : does not open any more.
Is there anubody who can help me ?
When you say first small screen I assume you are referring to the splash screen. If so you need to double click on a template or new project icon. You can also choose from the list of projects/templates on the left listing or choose a preset on the right. Just double click on what you want or select and choose open at the bottom of the window. Motion will then open for you.
