Appendix - Still Images and Computer-based Graphics
80 Harmony 2ES and 4ES
• Do not use white or red backgrounds that have more
than 80% saturation.
There are utility programs, such as Hijack and Debabelizer,
that will translate computer graphics into video-friendly
colors.
Adobe Photoshop includes a filter for NTSC colors.
Using the “Image Adjust” function in Photoshop to reduce the
brightness and contrast by about 25% will make the video
image better.
NTSC Safe Title Area
Unlike a computer monitor or a plasma display, television
monitors have some amount of “overscan”. This means that
graphics that are near the edges of the screen on a computer
monitor will not be seen on a television monitor.
The exact amount of this overscan will vary widely, but it is
generally considered safe to:
• Put graphics 10% of the distance from the edges. This
would mean that all graphics should be in the range of
72-648 horizontally and 48-432 vertically.
The aforementioned guidelines still do not guarantee that
graphics will be seen.
The “safe title” area is where text should be placed to be sure
that it will be displayed.
• The safe title area value is 20% from the edges. This
equates to the text being placed in the range of 144-576
horizontally and 96-384 vertically.
Text
• A font size of less than 12 points will usually be
unreadable on a video monitor or television. A minimum
size of 14 points can be used for “fine print”; however,
much larger text should be used for the text to be legible
in video.
• Anti-aliasing should always be selected for text.
• Detailed backgrounds should be avoided.
