If you don�t want to preserve the PowerPoint effects, you can convert it in movies using the Microsoft free softwares each (modern) computer may have:

1- After saving your ppt file (you may want to edit it in the future, therefore it�s a good idea to keep the original file), save it again as picture (gif or jpeg) � scroll down the options you have on the bottom of the saving window.

2- It�ll be asked if you want to save only that slide or all, choose �all�.

3- They�ll be saved in a folder with the same title as your ppt file.

4- Open Moviemaker (a free software provided by Microsoft, if you don�t have it visit the Microsoft page and download It for free).

5- Click �choose files� and insert all the files in your folder.

6- You can add effects, music, output format, etc.

7- You can also burn a DVD, including menus and it�ll look very �professional�.

I like to impress my students preparing this kind of project to present them, the only disadvantage is that some seem to be more interested in learning how I prepared it than in the subject presented.

Hope it helps.
