The problem is that many people feel they may need to learn coding or flash programming to do this. No fear, you can do this using some simple techniques.
Here is a small video on learning. While it talks about why learning is important and about Metamorph, it also gives you an idea of the kind of videos you can make -
either to distribute among your team or use in a presentation with a background score or narration.
PowerPoint has an excellent feature to save slides as JPG in the "Save As" option. The slides in my video too were imported from PowerPoint to Microsoft Movie Maker and then transition effect was added there. You can take a look at it here..
Micorsoft Movie Maker is very simple to do and easy to use. It is not very time consuming either, adding just 10 minutes to your work time. The software is also usually installed with Windows.
Another option, is that there are a number of photo album making software like Wondershare Photo Story or even Microsoft Photo Story (available for free for download). These softwares are also very easy to use and intuitive as they are meant for anyone to use. They allow you to add text, music and some amazing transitions . You can save them as EXE or video, distribute them on email, put them up on a shared server or even upload them to a website.
Since all these options are easy, simple and take very less time, they offer a great way to make your slides look different and interesting.
