PowerPoint Presentations for
Different Computers with Different Specs
~~Kathryn
Jacobs, PowerPointAnswersYou have this great idea for a PowerPoint presentation
that you want to send out for friends and family members to see. You
have worked for hours to get the timing of the animations and
transitions just right. You selected just the right music to go with the
pictures. You even created some great animated gifs to show how things
work and some movies to show what people can do with your information.
You copy your presentation from your hard drive to a thumb drive so
that you can take the presentation to your brother’s house to test. You
remember to put all the sounds, animations, and movies there also,
because you remembered how much fun it wasn’t to deal with those things
last time. You even remember to put a copy of the Viewer on your thumb
drive in case there isn’t a copy of PowerPoint on the other machine. You
are all set, or so you believe.
You get to your brother’s house and discover that you may have a few
problems to deal with. Luckily, his machine does have a USB port for
your thumb drive. But, as he so nicely reminds you, Mom and Dad’s
machine doesn’t have one. When you send it out, you will need to send it
on CD instead. You have just hit the first of many problems that exist
when you build a presentation that is going to run on many different
machines.
What is going to happen next you wonder, as you open PowerPoint on
your brother’s machine and run your presentation? Suddenly, all your
perfectly timed sounds, animations, and effects are running very
strangely. You can’t hear the sound effects – you only hear the music.
Your slides change very slowly. Not all of your movies run. And most of
your beautiful animation sequences just sit there!
What are you going to do? You are going to go back to the beginning
and make some changes to how you put the presentation together to start
with.
First: Think about the machines
Always develop on the oldest, slowest, and least powerful machine
that you expect the presentation will be run on. If you develop on a
high-powered machine, then run on a lower powered machine, you will have
many problems. The USB capability is one of those things.
If you depend on multiple effects happening at certain speeds,
PowerPoint will get you. As soon as you move to an older or less
powerful machine, PowerPoint will have to do more with less. You won’t
like the results.
If you are concerned that your presentation is going to be a resource
hog, make up a little cheat sheet for the people you are sending the
presentation to. Tell them to:
Turn off all other programs running on their machine.
This includes email and internet programs, definitely, and other
programs if possible. In the most extreme cases you will
need to figure out some way to prove to them that you don’t
have a virus embedded in the file, since they will need to
turn of the virus checker as well.
Clean out their temporary space, their browser history,
and to do other regular disk maintenance. The more hard
drive and temporary space PowerPoint has to use, the faster
it can run and the better it can meet your design.
Copy the presentation and linked files to the hard drive,
instead of running from the CD or thumb drive. Hard drives
are the fast things out there in terms of file access. Thumb
drives come next. CD drives are the slowest of the three.
Second: Know what PowerPoint versions people are using
If you are doing all your development on PowerPoint 2002 or 2003,
people with PowerPoint 97 and 2000 won’t be able to see all of what you
included in your
presentation. While the newer versions of PowerPoint will handle the
older animations, they will not look the same as they do on the older
versions.
Be sure that you include the right viewer so that they can see your
presentation the way you designed it. If you developed the file in
PowerPoint 2002 or 2003, you should provide the link to the "new" or
2003 Viewer. If you developed the file in PowerPoint 97 or 2000, you
should provide the link to the "old" or 1997 Viewer.
One last word of warning on PowerPoint versions: Animated Gifs don’t
run at all in PowerPoint 97. They run with infinite looping in
PowerPoint 2000. PowerPoint 2002 and PowerPoint 2003 do a good job of
interpreting the header information, so those versions should be fine
with the animated GIFs.
Third: Make your files small
The bigger your PowerPoint file, the more likely resource issues will
impact how your presentation runs. You need to make sure that your files
are the smallest size possible.
Turn OFF fast saves (Tools--> Options--> Save tab, uncheck
the box) and then save the presentation to a new name. If Fast
Saves were on, this step alone will cut your presentation size
by a good amount (usually 33-50%).
Read up on how to make sure your files are as small as
possible at the PPT FAQ (www.pptfaq.com). The biggest thing here
is to make sure your graphics aren’t over-scanned or oversized
and that you inserted them the right way. What’s the right way?
Insert > Picture – Not copy and paste!
Make sure your music is the minimum quality you can live
with. There is no reason to distribute a sound file that is CD
quality if the presentation is only ever going to be played over
a mono-speaker on a laptop. Play around with the quality of your
sound files and see what you can live with in the quality of
sound vs. size of file battle.
Fourth: Use fonts wisely
If you are using any unusual fonts, embed them. If you used anything
out of the ordinary and didn't embed them, PowerPoint on the other
computers will have to guess at the best possible match from the
fonts on the machine. This makes it so that there is very little chance
of everyone else seeing what you want them to see.
If you embed the fonts, you at least have a shot at them seeing what
you want them to see. Since not all fonts are embeddable, you may still
have some font problems, but they should be minimized. (Not sure if your
fonts are embeddable?
Go read last month’s article. While the
limitations on opening files with fonts in them is new to PowerPoint
2003, the information provided there on how to know if a font is
embeddable is old news.)
Fifth: Know the multimedia capabilities of the other machines
You can't control what other computers have for speakers. Most
machines won't play more than two sounds at a time. Most laptops will
have problems playing more than one at a time. If you need to have
multiple sounds to get your point across, you can forestall the problems
by editing your sound files so that all the sounds are coming from one
file. If that isn’t an option, be sure that you tell people they won’t
be getting the full effect without a somewhat fancy sound card.
If you are sharing presentations with movies, you need to be sure
that you have created the movies with the most common CODECs (these are
the files on your computer that tell the multimedia players how to
compress and de-compress your movie files so that they can play).
Sixth: Distribute the presentation correctly
Send the sounds with the presentation. Make sure the links don't
break when you move your presentation and the sound files around.
Information on that problem is also on the PPT FAQ website. Make sure
you save your presentation as a PowerPoint Show, so that it will play on
a double click (instead of opening in PPT's edit mode).
Seventh: Relax
Even if you set all of the above up perfectly, your presentation is
not going to run the same on any two machines. It probably won’t even
run the same two times in a row on the same machine. The differences
won’t be as noticeable on the same machine, but they are there.
If all else fails, and you need to have a perfectly timed, perfectly
repeatable presentation, then it may be time to consider using
another program to create or present your information. If you don’t want
to lose all the work you have put into the presentation, then look into
recoding your presentation or using

self-contained presentation package.
