The following pages show how to create DVD menus from
one
of these available menu templates or from your own menu background images using
Adobe Photoshop. Combining with Sonic Scenarist authoring package, you can create
menus with stunning professional quality by observing the following steps.
Step 1. Image Resizing. To preserve the 4:3 pixel aspect ratio (so that circles
look round on standard television screen), the images for DVD menus should be prepared
at either 720x540 resolution (recommended for NTSC video standard) or 768x576
resolution (recommended for PAL video standard). Therefore, the final images have to be
resized to 720x480 resolution for DVD NTSC and 720x576 resolution for DVD PAL. The
menu option Image Size... from the Photoshop's menu bar scales the prepared image to
its appropriate dimensions before importing to Scenarist.
Here we prepare the menu for a NTSC DVD so the image dimension is set at 720x480
pixels. We type in 720 and 480 as the width and height of the image, respectively.
We should note that the check mark for "Constrain Proportions" needs to be off so
that Photoshop will accept the specified width and height dimension as is without
recomputing to maintain the original width to height ratio. The default resample
image method is bicubic interpolation works well with photographic images (24-bit
color depth).
