Of AVI’s and CODEC’s

I’m playing with some screen capture software that grabs a desktop or window over time into an AVI file. From thence – most likely I will be importing things into PowerPoint. As such I am learning about CODEC’s which seem as inscrutable as anything I have encountered.

The CODEC provided with the capture software compresses the animations (15-30 second sequences) into smallish (200-500K) AVI files, some of the other CODEC options are much, much larger. I would hope to find something to use that is more or less standard / generic (i.e. – portable).

Looks like I have some research and perhaps experimentation ahead of me. Pretty useful capability to have for presentations, training, websites, tutorials, etc.
