Presentation Tip: Solving problems caused by embedding
Many presenters don’t realize
that PowerPoint embeds or links to other files or information in ways that can
cause problems. They may have experienced a PowerPoint file that has grown too
large to e-mail to someone else, or linked files or videos don’t work when they
take their presentation to another computer to present. In this article I want
to explain how you can fix four of the most common embedding issues I see when
dealing with PowerPoint presentations.
Why is embedding such an
issue? Because in almost all cases, there is no way the presenter knows about
the restrictions or problems until after they have occurred. PowerPoint doesn’t
give you warnings or notices to let you know that something won’t work the way
you expect it to. You have to find out the hard way.
One of the most common issues
is your PowerPoint file growing very large after you add some photos. They
could be photos of people or objects, but they make your PowerPoint file so
large you can’t e-mail it. What is going on? When you insert a picture on to a
slide, PowerPoint embeds the entire picture file into the PowerPoint file. And
that is the problem. Many photos are much higher resolution than PowerPoint
will ever need. Instead of only keeping the pixels it will use, PowerPoint
stores all the pixels in the picture. This makes your PowerPoint file much
larger than it needs to be. To solve this issue, there are two possible
solutions; both involve removing the pixels you won’t use, resulting in a great
looking picture that is much smaller in size. The first solution is one you use
before you insert the picture into your presentation. Use a program such as the
Microsoft Office Picture Manager (usually found in the Office Tools folder on
your computer) to resample or resize the photo to a more reasonable size.
Usually a standard size of 1024 x 768 will be sufficient to use a photo full
screen without any distortion. The second solution is to use the Compress
feature within PowerPoint for those photos you have already inserted on to
slides. This tool does a good job and you don’t have to take all the photos out
of your presentation and start again. This is one of the many tips on using
photos that I shared in a webinar earlier this year.
Another embedding problem
that most presenters don’t know about is unknowingly exposing confidential data
in spreadsheets. One of the methods for copying a table of information from
Excel to a PowerPoint slide is to use the Copy Special, Excel Worksheet Object
option. This method allows you to resize the table on the slide making it easy
for everyone to see. What it doesn’t tell you is that it embeds the entire
Excel worksheet, all the tabs and all the information, into your PowerPoint
file. Besides making your PowerPoint file bigger, it allows anyone who opens
the file to access your entire worksheet. All they need to do is double click
on the inserted object and it opens the full Excel worksheet on the slide. They
can navigate to any tab and see any information in that worksheet. When I
showed this to a client last year, the President was mortified to find out they
had been sending confidential data to clients without knowing it. Instead of
using the Excel Worksheet Object paste method, use one of the methods that does
not embed the worksheet in your PowerPoint file. I covered five methods for
inserting Excel data into PowerPoint in my webinar on using financial data in a presentation.
A third embedding issue, one
that is also hidden from presenters is using a video in a presentation in
PowerPoint 2007 and earlier versions (I’ll get to the issue about videos in
PowerPoint 2010 next). In the versions of PowerPoint that most of us use, when
you insert a video, it doesn’t actually insert the video file into your
PowerPoint file. It just uses a link to the video file that it accesses during
the presentation. The issue here is when you move the presentation to another
computer. That link stops working in many cases. Why? Because the link is
pointing to the specific folder on the original computer, which isn’t on this
computer. To solve this problem, make sure that the video file is in the same
folder as the PowerPoint file before you insert it on a slide. That way,
PowerPoint only needs to remember the file name, not the whole folder
structure. Then, make sure you move all the files – PowerPoint and video files
– to the new computer. The problem will almost always be gone. I covered many
more topics on using video in your PowerPoint presentation in this webinar.
In PowerPoint 2010, they
rewrote the way that video files are treated, partially in order to solve the
above issue. But they introduced another issue. In PowerPoint 2010, when you
insert a video on a slide, it embeds the entire video file into your PowerPoint
file. If you thought you have seen some large PowerPoint files with images,
wait until you see the size of some of these files. Some of them are too big to
even be put on a CD! You can try to compress the video, but often that will
reduce the quality of the video, which isn’t what you want for your audience.
An alternative is to use a hyperlink to the video file instead of embedding it
into the slide. The hyperlink will use the media player on your computer to
play the video. It is a little more awkward as a presenter, but it may be what
you need to solve the issue of outrageously large PowerPoint files due to
embedded videos in version 2010.
As a presenter, you need to
be aware of what PowerPoint is doing behind the scenes and how it can affect
your ability to deliver an effective presentation. Use these tips to help avoid
problems caused by how PowerPoint embeds different objects in your
presentation.

I was an offender of using high resolution crazy size images and when I would tell my husband the size of my presentation I would get the "are you crazy" look. It was a fast lesson for sure.
at my work the professor is always having problems with broken links in his powerpoint presentations when sending to other. I believe he is using 2011 or 2012 but I wish there was an option to "embed all" just so we wouldn't have to worry about broken videos or clips. We don't care for the size of the ppt file, we just want it to work.
