NTSC 4 X 3 Video Menu graphics: 
To ensure your image will be the right size and resolution, select the “NTSC DV 720 X 480 (with guides)” preset when creating a new file. If this preset is unavailable, use a starting canvas size of 720 X 540 pixels at 72 dpi and design to your satisfaction.  Before exporting, resize the image to 720 X 480, as the pixel shape changes from the square type used on computer monitors to the rectangular ones found on television monitors.  Otherwise, your image will look “stretched” when viewed on a monitor.  Export the file to TIFF format with layers, in case any changes must be made by the DVD Author.

Sub-pictures (Button Highlights)  Sub-pictures must exactly match the underlying artwork of a menu screen.  They are composed of only four colors: Black, red, blue, and white, all of which are 100% color values and therefore heavily aliased.  It is critical that the sub-picture have exactly the same screen dimensions and placement as the menu screen. For still menus the sub-picture size is 720 X 480 pixels at 72 dpi.  You must also send the RGB Values you want for the final sub-picture colors.  This will indicate the color you want for the highlight to the DVD Author. There are a few other general things to consider when preparing graphics for television monitors which will ensure your screens end up looking like you intend them to look.

• Design your menus using NTSC colors. There is filter in Photoshop that will convert a standard RGB palette to NTSC safe colors.
• Avoid using thin horizontal lines or serif fonts smaller than about 24 points. They cause problems on television screens. If using text as a button, set anti-aliasing to “Crisp”, if possible.
• Use a title safe grid when creating your menu compositions.  This is included in the Photoshop preset.

Finally, remember that your designs are primarily functional and intended to make navigation easy and obvious. A cluttered screen with obscure icons or small text can result in user frustration and product alienation
