Was doing some planning for next year when I got sidetracked looking at OSX system audio. I plan on using screencasts as an assessment tool so I started playing with Quicktime Player to see what I could do.
As my grade eights are illustrating a grade one book using scratch I thought I would try to create a screen cast of one of the books (day two on the project). Quicktime Player allows you to record, built-in camera video, audio and also the screen. It also lets you share videos you create to Youtube, Vimeo and export to web, your desktop or to iMovie for further editing. The first thing I found was that I could not really hear the audio from the Scratch screen recording. After a quick google search I found a tool I had forgotten about: SoundFlower. I installed SoundFlower from here, restarted my Macbook and tried it out.
In the Sound control panel I set my audio input to SoundFlower (2ch). When I started my Quicktime screencast I choose SoundFlower (2ch) from the triangle on the side. I recorded the Scratch story then sent it to Imovie to add a title and from Imovie exported it to Youtube took all of five minutes.
Here is the book so far.
