Media Elements (Continued)
Whenever possible, use a graphic in place of a photo. If a photo is
Photos/Graphics
absolutely needed, then use a digitized photograph that has proper
lighting, angle, focus and scale. Graphics and photographs should be
designed to run/display using thousands of colors or standardized
color palettes if possible. Otherwise use the same color palette for all
graphics.
The learner should control initiating video and animation sequences
Video/Animations
and should have the option of repeating them. Video and animations
should be large enough to effectively convey information. Be aware
that high quality video files require large amounts of hard disk space.
Audio should always complement the text and visuals. Audio should
Audio
not include extraneous information, unwanted sounds or inappropriate
pauses. Narration should be attractive, credible and engaging with
appropriate volume, pace and tone. Narration should not mimic the
text. Be aware that large, high quality audio requires large amounts of
hard disk space. You should use a professional narrator. Professional
voices add the correct emphasis and interest to the narration.
Approximately seven seconds of narration is the maximum
recommended for a single piece of narration. Chunking sound is just
as important as chunking text.
Create libraries (see glossary) of your media elements for each
Media Management
project. This organizes content and conserves disk space for
multimedia projects.
Use a consistent naming convention for media elements. For
example:
softleft_Pb - is a push-button
sec5_Timer - is a 5 second timer
rpm_Ind - is an RPM indicator
volume_Sw - is a volume switch
Text files of spoken audio clips should be maintained for later
revisions.
