The article "Multicam Video Editing Tips" was very practical and should help people who want to do multicamera shoots. Similar techniques can be applied to dual-system audio productions, where the audio is recorded onto a separate recorder instead of the camera. For example you might want to take a feed from a soundboard into a portable audio recorder like the Zoom H4. This really simplifies the recording because you don't have to run a cable to one of the cameras.
There is another option for doing the synchronization. Our company is developing a product called PluralEyes that does it automatically. It is currently in beta testing and we welcome new testers who would like to try it out. There's a short video here that shows how it works and the variety of multicamera productions that the independent video producer might want to consider.
