Formats for tutorials and screencasts

So we need to decide upon a format for all the learning videos that we'll be creating. Here is the rough format that has been proposed by @nelsonic in the discussion we've had earlier.

1. Brief Intro (30 sec)
- name and what the topic you are covering
2. Show the end result (1 min)
- What will the user see at the end of the tutorial, this is important as we don't want the user to sit through the whole video if the end result is not what they are looking for
3. Run through the tutorial (4 - 5 min)
4. Retrospective / debrief
- tell them what they've achieved and also to find us on GitHub etc.

This would mean that individual videos are no longer than 6 -7 mins. If a video has more content, we can split it up and have it as parts. (e.g. part - 1, part - 2)

What do you think of the format? Feedback Welcome!
