Images should not be too sharp. Sharp, high-contrast edges and fine horizontal lines may
flicker when viewed on a TV. Apply a blur filter in your image-editing application to remove
hard edges.

Recommended image sizes
Menu backgrounds
Recommended image sizes for menu backgrounds are:
Images at these sizes fill the menu area without distortion or scaling artifacts. You can use
other sizes; DVDit Pro HD has several options for scaling menu background images. See
“Scaling of non-4:3 images and video” on page 108 .
For 4:3 menu back grounds, you can create images at the above sizes, then resize them in a
graphics application to the NTSC or PAL screen resolutions (720 x 480 for NTSC,
720 x 576 for PAL). Although the image appears distorted in the graphics application, it
displays correctly in DVDit Pro HD and on the finished DVD.
n
Most TVs do not display the entire image. The edges are cropped to hide distortion, and only
about 90% of the image is visible. See
“Safe Area guides” on page 104 for details.
Buttons
Button images should be created at the size that you want them to be on the finished
menu.You can resize buttons in DVDit Pro HD, but you get better results (and menu
creation is quicker) if you make your buttons the right size. A menu with a 720 x 480
background may be best served by buttons that are 50-100 pixels wide whereas a menu with
a 1920 x 1080 background may be best served by buttons that are 150-300 pixels wide. You
can determine the best button sizes for your menus by creating menu backgrounds in a
application such as Photoshop and by laying out buttons of varying sizes on those menu
backgrounds.
