You can use your iSight camcorder to record video directly into your iMovie project. This means you can spontaneously add clips to your project while you're working on it. Just connect your iSight camcorder to your Mac's FireWire port, and you're ready to start recording. If you have more than one camcorder connected, such as an iSight and a camcorder, or you have an iMac with a built-in iSight-choose iSight from the pop-up menu that appears when you switch to camcorder mode. Alternatively, you need to convert the camcorder to iMovie compatible video formats, such as MOV.
