Screencasting Framework

The following document is a written account of the Code School screencasting framework. It should be used as a reference of the accompanying screencast on the topic.

Why you should care about screencasting?

You're probably aren't going to take the time to read this document if you're not interested, but there are a lot of nice side effects caused by learning how to create quality screencasts.

1. Communicating more effectively - At Envy Labs we produce screencasts for our clients all the time. Whether it's demoing a new feature or for a presentation for an invester, they're often much more effective and pleasent than a phone call or screen sharing.
