Panasonic P2HDXAG-HPX500 사용자 설명서

Next-generation camcorder media aimed at professionals, including hard disk drives (HDD) and Blu-ray discs

(BD) vary in shapes and structures. However, their main advantage is probably that the data on the media used

for shooting does not need to be digitized, meaning that it is ready for immediate use in non-linear editing (NLE)

systems. Whereas HDD and BD both require specialized input devices (docking stations or dedicated drives), the

P2 (Professional Plug-in) card system proposed by Matsushita provides the benefits of solid-state memory,

including durability, portability and freedom from mechanical issues. This gives it numerous advantages over

other media as a recording system for professionals. In recent years, a key issue for all production sites has been

ensuring that their recording media works smoothly with their PC systems. In this regard, because they can be

used in existing PC card slots and allow data to be transferred directly to notebook PCs with ease, Matsushita's

P2 cards offer an extremely convenient and efficient media system in comparison with other non-contact media.

A 16 GB P2 card will hold roughly 16 minutes of broadcast-quality HD format 1080i signals using DVCPROHD

mode, or around 40 minutes of 720p mode recording in 24p native mode. Clearly, the key limitation is the short

absolute limit on recording time when compared with existing tape-based recording and other formats. But when

we consider the prospects for future development and the future of the SD memory cards that provide the basic

technology for P2 cards, it is also apparent that these problems are only short-term issues and will soon be

overcome.

And while other media provide only one means of access (recording) for each recording (shot), the P2 system

provides a Hot Swap function that allows multiple cards to be inserted in parallel for sequential recording. This

means that 2 or more P2 cards can be used to record indefinitely without disconnecting the backup line.

Looking at the development roadmap for the future of P2, the capacity is slated to double each year while the

cost per unit of capacity will fall. For instance, with the 32 GB P2 card planned for release at the end of 2007, it

will be possible to shoot continuously for approximately 2 hours on the new AG-HPX500 introduced here, since

that model comes with 4 slots, each of which will store 32 minutes of HD recording. Even on its predecessor the

AG-HVX200, it will be possible to record 1 hour of HD video, recording 32 GB in each of its 2 slots. And given that

later models will support the new AVC-Intra data compression codec, P2 media clearly have a bright future. With

such strong future prospects, the P2 card system will surely become the media of choice for core photography

flow systems at professional sites of the future.

This guidebook is intended primarily for AG-HVX200 users or those who are running tape media operations

(DVCPRO, DVCAM, etc.) with conventional SD, and provides straightforward descriptions of the procedures and

settings for a basic photography, recording and editing system capable of creating and handling HD productions

using the AG-HPX500 and the P2 card system.
