Here are two example video introductions using two different tools.
Example 1: Photostory 3
A free piece of software (http://www.microsoft.com/en-gb/download/details.aspx?id=11132) that takes photos and allows you to add narration, music and some effects. Moviemaker software will do in it's place.
The module was a MSc Computing dissertation module giving a short overview of the module.
Example 2: Machinima
A second approach was to use a package that allows you to guide/direct a character, scripting what they say, etc. The package used was an early version of Moviestorm (newer educational version can be foundhere) it allows you to 'direct' the character and save me having to appear in it! Please ignore the repeating this was part of my experimentation.
This module is an introduction to artificial intelligence module.
Ok, they were done as a couple of experiments and a bit a fun; but are worth a play with.
