Use vector shapes and masks, rather than bitmap, where possible, because scaling these elements

does not affect their quality. If creating pixelated content, such as buttons and logos, make sure that you create them
at the largest size needed for the DVD. If you need to resize some elements, it is better to scale a pixelated object
down, rather than up. (Scaling images up can cause quality loss; scaling images down does not.)
Create your images using RGB color. Convert any CMYK images to RGB before importing them into

colors in your graphics application that may be beyond the color range that NTSC televisions can display. These
colors can cause an unwanted halo effect. Use RGB values between 16 and 235.

Understanding layer name prefixes for Photoshop menus
For Adobe Encore DVD to recognize the components of a menu from Photoshop, you must add predefined prefixes
to the layer names. The prefixes identify the layers as button sets, video thumbnails, replacement layers, and button
subpictures. This lets you import a finished menu that is ready to use in the project. You can also manipulate and
change elements from within Adobe Encore DVD.
Instead of creating menus from scratch in Photoshop and adding all the prefixes manually, you may want to open a
menu template that's similar to the one you want to create, save it as a Photoshop file, and then edit the exported file
in Photoshop.
