Sharing PowerPoint presentations as videos or web-pages
PowerPoint presentations are a deservedly popular method to present
information to students or to other educators.
Slideshows built using PowerPoint can also have value when viewed by
individual, or groups of students.
However, a number of factors limit the "sharability" of these
Some versions of the MS-PowerPoint application may have
difficulty running presentations created with a different
Some versions package all needed files (including
audio and video) into the presentation, while
other versions keep them as seperate files that must be in a
specified (relative or absolute) filesystem location.
Open source tools such as "LibreOffice" and "OpenOffice" have
similar presentation tools, but these often do
not display PowerPoint files in an acceptable way.
However, all is not doom and gloom! PowerPoint
presentations can be used as the "source" to
generate both videos or web-pages that are usable from a
standard web browser.
Video files based on PowerPoint presentations
can be generated from within the application itself.
A couple of important notes:
Video output is dependant on either explicitly set
timings for advancement of slides or on
a standard advancement interval. If you
need a "pause" of undetermined duration, you must
add an on-screen cue telling user to manually pause
Use of the "Transitions" mechanism to add
audio is not properly supported in video output.
Instead you must use the "Animations" mechanism.
Since a video must follow a single, determined
flow, you cannot convert "game" presentations,
(such as "Jepardy") using video.
A variety of companies provide software tools to
convert PowerPoint presentations to web pages.
"iSpring Free" is a good ( $0 ) tool.
It is available from iSpringSolutions.com.
Web versions of presentations can be configured with
automatic timings, or left for total control by the user.
Random flow game presentations can be done with Web
