Multimedia presentation
-
A multimedia presentation differs from a normal presentation in that it contains some form of animation or media. Typically a multimedia presentation contains at least one of the following elements:
- Video or movie clip
- Animation
- Sound (this could be a voice-over, background music or sound clips)
- Navigation structure
- Choice of multimedia presentation technology
- The first – and hardest – part is to choose the technology for your presentation. The choice comes down to two main contenders, Adobe Flash or Microsoft PowerPoint.
Adobe Flash
-
Flash allows you to create presentations where you can build in powerful animation. It also has very good video compression technology.
-
Perhaps the best part of Flash is that it also allows you to put presentations directly onto your web site.
-
The biggest problem though is that Flash is a difficult system to get to use. I have been on a training class and also have access to a couple of graphic designers for help and still find it difficult to put together a presentation in Flash.

For an example of a Flash presentation that includes a voice-over and animation click on the picture on the right.
-
Life has become a lot easier in the recent versions (Flash 8 and Flash CS3). With these versions there is a new feature called Flash Slide Presentation. Rather than the conventional time-line it allows you to build and add in slides a bit like the slide sorter in PowerPoint.
-
It is also very expensive. Checking on Amazon the latest version of Flash (CS3) will set you back £515 ($629.99). You will probably have to factor in around £400 for a decent Flash training class.
-
There is a low cost alternative to Flash called Swish. They make it easy to build a Flash presentation without the need for detailed programming knowledge. For a free trial of the software you can visit the Swish website at www.swishzone.com
Microsoft PowerPoint
- The easiest way to create a multimedia presentation is in Microsoft PowerPoint. You can add in video, a soundtrack and also a reasonable degree of animation.
-
By far the the biggest advantage of making multimedia presentations in PowerPoint is that it is easy for anyone to be able to edit the presentation.
-
An example of how you can introduce multimedia effects in a presentation is shown in the taxi sequence on the right. It starts with a line drawing being made on the screen and is then followed up with a taxi fading in.
- The sequence is part of one of our PowerPoint templates. You can see the effect in action by downloading the taxi animated template from the download page. Make sure that you view the sequence in PowerPoint show mode.
- We have a number of tutorials on the Presentation Helper web site that make it easier to put together a multimedia presentation.
- How to add video clips into a PowerPoint presentation
- How to add music into PowerPoint
- Simple menus in PowerPoint
- How to animate your slides
If you put together a number of these elements you will have a way to create a multimedia presentation in PowerPoint.

C. The unsanitary conditions in cattle feedlots.
Explanation:
E. coli O157:H7 is a type of bacteria that can cause several symptoms in humans, including abdominal cramps, bloody diarrhea and vomiting. While most adults can recover from it easily, young children and older adults can develop serious complications. One of the reasons why this bacteria spread in the United States was due to the unsanitary conditions in cattle feedlots.
