From the developer:
CaptureSync is a multi-camera capture application for Mac OS X. It takes video and audio streams and records them to a single file, containing all streams synchronized together.
CaptureSync is perfect for recording events from multiple camera angles simultaneously: interviews, scientific experiments, psychological research, musical performances, sporting events, market research, lectures and presentations.
