Safe Area - an industry standard display area has been created to ensure that an
animation, graphic or text will be seen on an NTSC screen when transferred from a
computer using an RGB screen. An "action safe" area is where movement will most
likely be seen. A "title safe" area is where stationary text or graphics will be sure to
be seen. For instance, for NTSC, Action Safe = 432 x 576, and Title Safe = 384 x
504. But every monitor or television displays the signal it receives differently: Some
will show less than the outer edge of the "Action Safe" area. Therefore, if there is
anything that definitely must be seen (mainly stationary text and graphics) then it
must be placed within the "Title Safe Area.".
Text - Use at least 18-24 point type. Use 96 point type or greater for text when
output needs to be seen from a distance of about 20 feet or more. Rule of thumb:
Text should stay on the screen long enough for someone to read it at least twice.
Use drop-shadows or 3D lettering to set titles apart from the background.
Colour - Avoid using drastically contrasting colours side by side. Use “in-between”
colours to soften the transition. Use shades of grey instead of pure white to avoid a
washed-out look.
6.4 MPEG Backgrounder
This section is included for you as a refresher. We expect people who create play
lists to know most of this already!
What is MPEG?
MPEG stands for “Moving Picture Expert Group”, - a working party of the ISO – IEC
Joint Technical Committee 1, working on algorithm standardization for compression
of motion video.
MPEG-1 ISO standard designed for low resolution of compressed digital video and
audio (for the web, Video CD, etc)
MPEG-2 ISO standard designed high resolution compressed digital audio and
video such as that used by broadcast television (DVD uses this format).
What do you need to create MPEG files?
Before you are going to create the MPEG files (.mpg), you need:
• Camera (used to capture video movie or still picture)
• Video Capture Card
• MPEG encoding hardware (for MPEG encoding)
• MPEG encoding software
6.5 Creating .MPG files
The extension “.MPG” covers MPEG-1, MPEG-2 and MPEG still files. How you
create MPG files depends on the MPEG encoding method used and the source of
your video input. The MPEG encoding system includes both hardware and software.
(e.g. Optibase, or a fast PC with the right PC-software).
