AG-HPX255/HPX250
Full-Pixel, Full-Sample AVC-Intra Recording
These are the first handheld camera-
recorders to support the AVC-Intra
codecs of the P2HD Series for HD
recording of broadcast and movie
images. Featuring a high compression
ratio based on the new MPEG-4 AVC/
H.264 moving picture compression
technology, this advanced system
maintains intra-frame compression to
provide both high image quality and
excellent editing performance.
It offers recording and playback of
both AVC-Intra 100 and AVC-Intra 50 modes, and also supports
DVCPRO HD recording and playback.
•AVC-Intra 100: 1920 x 1080,* 10 bit, 4:2:2
High-quality images with full-pixel HD and full sampling are recorded at
the same bit rate as DVCPRO HD, bringing agile mobility to high-end
production.
•AVC-Intra 50: 1440 x 1080,* 10 bit, 4:2:0
Image quality is the same level as DVCPRO HD, but with the SD (DVCPRO
50) bit rate. You get twice the recording time of DVCPRO HD, and about
half the required data transmission time.
* These figures are for 1080i/p mode. The AG-HPX255/HPX250 also supports 720p mode.
Multi-Format Recording with Native 24p/25p Support and More
•Native recording modes:
In addition to 1080/59.94i with the AVC-Intra
codec, native recording is supported at 1080/23.98p or 1080/29.97p and
1080/25p. In 720p, native recording is possible for both DVCPRO HD and
AVC-Intra, making it possible to extend recording time by 2 to 2.5 times
in comparison with pull-down recording.
*Camera through output and playback image output are pulled-down 59.94 (50) frames.
•Pulldown record mode:
This VariCam-compatible mode records*
1
with
the DVCPRO HD codec. A 2:3 pulldown is applied to 23.98p, and a 2:2
pulldown is applied to 29.97p, to record 1080/59.94i or 720/59.94p and
1080/25p over 50i or 720/25p over 50p. The 23.98pA (2:3:3:2 advanced
pulldown) mode is also supported, allowing editing on applicable
nonlinear systems*
2
with little image degradation.
•59.94Hz/50Hz selector:
Supports worldwide HD/SD production.
•SD image acquisition:
The DVCPRO 50/DVCPRO/DV multi-codec
enables 480/576 image acquisition, with aspect ratio conversion. Select
from Side Crop, Letter Box and Squeeze modes.
*1: Not compatible with the AVC-Intra codecs.
*2: See the following website for details on applicable systems.

High Quality/16 bit, Four Channel Digital Audio
The AG-HPX255/HPX250 can record high quality/16 bit digital audio on
all four channels. You can freely select the audio source for each
channel, choosing from built-in mic, external mic and line-in. Level
volume is also supported on all four channels.
Double Slot System with Two P2 Card Slots
In addition to allowing continuous recording onto two P2 cards, this
system offers the following functions.
• Card select:
The recording slot can be switched in Standby mode.
• Hot-swap recording:
The card in the standby slot can be exchanged
while the other card is being recorded on.
Reliable, Large-Capacity P2 Card/microP2 Card Media
In addition to the conventional P2 card, the
AG-HPX255/HPX250 accommodate the compact,
lightweight microP2 card.*
1
Along with the
semiconductor's inherent resistance to impact,
vibration and temperature change, this new media,
unlike tapes and discs, has no rotating or physically
contacting parts during recording and playback – for
increased reliability. The microP2 card also features a
Content Protection System (CPS) that enables
password data locking to further bolster security. Both the P2 card and
microP2 card offer a maximum capacity of 64 GB*
2
for extended
recording time (see page at right). Both cards are designed to stand up
to repeated, long-term use.
*1: You may need to update its firmware. Please refer to the “service and support” on the Panasonic
Website (http://pro-av.panasonic.net/). Requires the optional AJ-P2AD1G Memory Card Adapter to use
the microP2 Card . *2: Total card capacity includes space for data management such as system data;
therefore, the actual usable area is less than the capacity indicated on the card.
Versatile MXF File-Based Recording
File-based recording onto memory cards enables high-speed starts,
recording starts with no need for cueing, and protection against
accidental data overwriting. The recorded data is organized into MXF
files. The files can be transferred to a nonlinear editor or over a network
without the need for digitizing.*
*PCs must be installed with the included P2 driver in order to mount P2 cards. For editing, PCs must be
installed with P2-compatible editing software available from various companies. Read "Notes Regarding
the Handling of P2 Files Using a PC" on the back page.
