I kind of forgot about the idea of writing in my blog so that I can find the answers again via Google. Well here's a quick one: How to backup the entire contents of your webcam (I own a Sony HDR-XR150) to a "Camera Archive Folder" on OSX.

1. Open up iMovie
2. Go to "File > Import from Camera" or the click big camera button under the Project Library pane
3. Click the "Archive All" button beside "Camera: Sony HDR-XR150"
4. Choose a location to save the entire contents of your camera (I use portable hard drives)

After doing this, you'll have a "Camera Archive Folder" where you can import movies into iMovie for your editing pleasure.
