Panasonic is currently shipping a wide range of camcorders that support the P2 format, including the professional video camera AG-HVX200 HD handheld camcorder, and the high-end, or broadcast professional shoulder-mount AG-HPX500, AJ-HPX2000, and AJ-HPX3000 camcorders. The first pieces of equipment released by Panasonic which use the P2 format included the AJ-SPX800 (a 2/3' broadcast camcorder for ENG and EFP applications), the studio recorder AJ-SPD850, the AJ-PCD10 offload device (basically, a five-slot PC card reader with USB interface designed to fit a 5-1/4' IT systems bay), and the memory cards themselves – AJ-P2C004 (4 GB) and AJ-P2C002 (2 GB). The card also contains a processor that organizes and safeguards the files and the case is developed and crafted to 'military' (according to Panasonic) specifications, making P2 cards tough and reliable. P2 cards are of a ruggedized PCMCIA type with the fastest transfer speeds currently available through this format.

Unlike video tape, old video cannot be recorded over accidentally old footage must be manually deleted. If a card is partially full, the deck will record only until it is full.

This limits recording time only by power supply and the available number of cards. Cards are recorded in sequence, and when a card is full, it can be swapped out while another card is recording. To solve this, camcorders and decks using P2 media employ multiple card slots, with the ability to span the recording over all slots. At introduction, P2 cards offered low recording capacity compared to competing, video tape-based formats (a miniDV tape holds roughly 13 GB of data, and an S-size HDCAM tape holds 50 GB). The cards can also be used directly where a PC card (PCMCIA) slot is available, as in most older notebook computers, as a normal hard disk drive, although a custom software driver must first be loaded.Īs of early 2010, P2 cards are available in capacities of 4, 8, 16, 32 and 64 GB. The system includes cameras, decks as drop-in replacements for videocassette recorders (VCR), and a special 5.25-inch computer drive for random-access integration with non-linear editing systems (NLE). The P2 card is essentially a RAID of Secure Digital (SD) memory cards with an LSI controller tightly packaged in a die-cast PC Card (formerly PCMCIA) enclosure, so data transfer rate increases as memory capacity increases. It features tapeless (non-linear) recording of DV, DVCPRO, DVCPRO25, DVCPRO50, DVCPRO-HD, or AVC-Intra streams on a solid-state flash memory. P2 (P2 is a short form for 'Professional Plug-In') is a professional digital recording solid-state memory storage media format introduced by Panasonic in 2004, and especially tailored to electronic news-gathering (ENG) applications.
