About File-Based Media
Historically, video footage has been recorded on videotape. As digital acquisition
quickly replaces analog technology, camcorders are starting to record footage as files
on non-tape-based media such as hard disks, solid-state cards, and optical discs.
Today, some common file-based media formats include:
 Panasonic P2 cards (solid state)
 Sony Video Disk Unit devices (hard disk)
 Sony XDCAM and XDCAM HD (optical disc)
