I'm going to be creating a SD-DVD and blu-ray for a client. Both DVD's are going to have the same navigation and design and menus. My plan is to do all my design in HD - 1920x1080...all my motion menus...etc.
Then just down scale them (in After Effects / Photoshop) to create a widescreen SD-DVD.
Is there an easier way to create a SD-DVD and Blu-ray from the same source content? Or do I need to create both independently and author the DVD twice like I'm planning to do.
