7.1.2. Primer on Creating Logos
The 3025EMC hardware executes the keying and display of logos, however, the user is responsible for
composing the image design. Unfortunately, the image created by the artist is not always generated
the same when it is keyed into and displayed on the video. These following sections will introduce the
user to some basic principles associated with keying graphical information on video. It will also provide
some guidelines when preparing logos to get the best quality possible.
Evertz Overture™ software imports the user’s image, formats it, and sends it to the EMC hardware. If
the user is already familiar with the creating images for use on video, please refer to the summary in
section 7.1.2.9 for a brief overview.
