The Panasonic AG-HPX250 P2 HD Handheld Camcorder
is the first handheld professional camcorder model to record the
extremely high-quality AVC-Intra 100 Mb/s (10-bit 4:2:2) codec.
Featuring an integrated 22x zoom lens and a 2.2 Mp 1/3"-type 3MOS
imager, the versatile HPX250 records not only AVC-Intra but also several
flavors of DVCPRO (including DVCPRO HD) as well as DV. A variety of
frame rates are possible in DVCPRO modes, for native slow- and
fast-motion effects.
For video that will later endure heavy processing in the form of
effects and other processes, the intra-frame compression options of the
HPX250 are crucial. The AVC-Intra 100 codec is a perfect choice for any
projects that involve tasks such as greenscreen shooting. The HPX250
could thrive as the second camcorder on an independent feature
production, or as the go-to model for a freelance videographer who does a
variety of jobs, from SD to HD � and with support for PAL/NTSC signal
systems, it will cross oceans without missing a beat. Its compact size
makes it hard to leave at home.
For rock-solid reliability, professional P2 cards (sold separately)
provide more peace of mind than their SD brethren from the world of
mass-market consumer electronics. With two slots, you can record either
simultaneously (for creating an instant back-up) or sequentially, with
hot-swap support.
- Panasonic Optical Technology
- The HPX250's high-performance 22x zoom lens was designed
specifically for professional HD video production. Sharing the
wide-angle capability found in the DVX and HVX series, the lens offers
some additional telephoto capability for a 28-616mm (35mm equivalent)
zoom range. The lens combines 18 elements in 12 groups and adds an
ultra-high refractive (UHR) glass element, a low-dispersion element, and
aspheric elements. Unique to Panasonic, Chromatic Aberration
Compensation (CAC) technology minimizes color bleeding in the
surrounding image and achieves rich expression by way of finely rendered
nuances and excellent shading
- Manual Control Rings
- Three manual rings � mechanical (cam-driven) zoom, focus, and
iris � allow you to operate as if you've got an interchangeable-lens
camcorder, for fine, tactile control over the parameters of the captured
image
- Optical Image Stabilization
- To compensate for any shaking of the operator's hand, the HPX250 features an optical image stabilizer (OIS)
- High-Sensitivity, Low-Noise 3MOS Image Sensor
- Thanks to Progressive Advanced Processing (PAP) technology, high
sensitivity up to F10 (F11 in 50 Hz mode) is possible, for low-noise
performance in dimly lit environments. The 1/3-type 2.2 Mp 3MOS sensor
features the same Ultra Luminance Technology (ULT) that's incorporated
in Panasonic's shoulder-mount P2 HD broadcast camcorders. This sensor
maximizes the performance of the lens and the signal processing circuit
in standard conditions
- Flash Band Compensation
- The CMOS sensor system uses a rolling shutter system that
sequentially scans each line of pixels, thereby lowering power
consumption vs. CCD cameras and enabling high-speed drive. But because
the exposure timing differs for each line, when an external flash is
used, it tends to produce images with a "divided" level of brightness
from top to bottom. The HPX250 ameliorates this "flash-band effect": it
detects by comparing frame pairs and compensates to adjust the level
- 20-Bit Digital Signal Processor
- The AG-HP250's high-performance 20-bit DSP handles rendering
processes such as gamma and detail-enhancement functions with uncommon
precision
- Dynamic Range Stretch (DRS)
- The DRS function automatically suppresses blocked shadows and
blown highlights in scenes that involve wildly varying contrast levels
(such as indoor vs. outdoor elements in the same frame). DRS estimates a
gamma curve and knee slope to match the contrast of each pixel and
applies them in real time, producing excellent gradation for each shade
and minimizing blocked shadows and blown highlights
- Seven-Mode Gamma for Rich Gradation
- Drawing upon the technology of the high-end VariCam line, the
HPX250 features gamma functions for seven shooting scenarios, including
two cinema modes: HD NORM (for standard HD recording), LOW (flattens out
a high-contrast scene); SD NORM (for standard SD recording); HIGH
(softens contrast and expands the tone of dark parts, making an image
brighter); B.PRESS (sharpens the contrast compared to LOW); CINE-LIKE D
(prioritizes dynamic range); and CINE-LIKE V (prioritizes contrast)
- Other Camera Image Settings
- The camera's shutter speed is variable from 1/6 to 1/2000
second, plus there's a Synchro Scan function. As with gamma, matrix
setting includes a Cine-Like mode. H & V detail levels are
adjustable, as are detail coring and skin-tone detail. That's not all:
chroma level, chroma phase, color temperature, and master pedestal are
all adjustable as well. The camera offers four settings for knee point:
Auto, Low, Mid, and High
- Focus Assist Function
- A convenient Focus Assist button expands the center of the LCD
screen, allowing you to check for correct focus quickly & easily. A
Focus Bar that indicates the focus level can be displayed on the LCD
- Scene File / User File
- The HPX250 features a dial for "Set Scene," which allows you to
choose an appropriate matrix of settings instantaneously. You can
modified the six preset files if you'd like, one set of which can be
stored internally in the camcorder, and four more can be stored on an SD
memory card
- Three-Position Gain Selector + Super Gain
- The three-position Gain Selector contains Low, Medium, and High
settings. To each setting you can assign gain value of 0, +3, +6, +9,
+12, +15, and +18 dB. Also, there are Super Gain settings of +24 and +30
dB
- Simplified Waveform & Vectorscope
- The AJ-HPX250 has waveform and vectorscope display functions for analyzing a captured video signal on the LCD
- Five User Buttons
- A total of five user buttons can be set to trigger any selection of 18 different camera functions
- Full-Pixel, Full-Sample AVC-Intra Recording (10-Bit, 4:2:2)
- The HPX250 is the first handheld camcorder to offer 10-bit
AVC-Intra recording (at both 100 and 50 Mb/s). Based on highly advanced
MPEG-4 AVC/H.264 compression, this codec employs intra-frame
compression, which results high image quality � especially in the edit
suite, where inter-frame codecs can start to break down. Both
AVC-Intra 100 and 50 modes are offered � as is DVCPRO HD, for
compatibility with that very popular format. For 1080i/p, AVC-Intra 100
uses full-pixel 1920 x 1080 frames, with 10-bit quantization (4:2:2).
The very bit-efficient AVC-Intra 50 codec records 1440 x 1080 video at
10-bit, 4:2:0
- Native Recording & Pulldown Modes with PAL/NTSC Support
- For cinematic 24-frame-per-second projects, the HPX250 supports
1080p recording at 23.98 fps (29.97 fps is also possible). For PAL
regions, the camcorder is capable of recording at 1080/25pN and
720/25pN. The camcorder also records natively (without pulldown) in 720p
modes, which results in recording efficiency that allows you to record
for 2 to 2.5 times the duration allowed by pulldown recording. In
pulldown mode with the DVCPRO HD codec, the camera applies a 2:3
pulldown to 23.98p, and a 2:2 pulldown to 29.97p, to record 1080/59.94i
or 720/59.94p and 1080/25p over 50i or 720/25p over 50p. With 2:3:3:2
advanced pulldown, the 23.98pA mode is supported, allowing editing on
many NLE systems with little image degradation. The camcorder also
features a 59.94/50 Hz selector for worldwide compatibility and SD image
acquisition with either 480 or 576 lines and aspect ratio conversion
(select Side Crop, Letter Box, or Squeeze). This is an internationally
compatible camcorder that can fit seamlessly into almost any production
workflow
- High-Quality 4-Channel Audio
- The AG-APX250 records high-quality 16-bit audio on all four
channels. Freely select the audio source for each channel, choosing from
built-in mic, external mic, and line in. Adjust the volume level for
each channel
- Rock-Solid Recording with P2 Cards
- P2 cards are built tough for broadcast applications � this is
not a consumer storage technology that migrated into the professional
world. P2 offers 64 GB capacity and resists impact, vibration, and
temperature changes. The recording format withstands repeated recording
and initialization cycles for an extended product lifetime. The
connector section of the card is designed for the type of blithe
insertion and removal that is inevitable on a high-pressure production.
For a solid-state recording format, P2 is downright venerable, with a
proven track record in the worlds of movie production and broadcast
- Double-Slot P2 Card System
- Not only can you record continuously on two P2 cards, but you
can also choose Card Select mod (which allows the recording slot to be
switched in Standby mode) and Hot-Swap Recording, in which the card in
the stand-by slot can be exchanged while the camcorder is recording to
the other card
- MXF File-Based Recording
- File-based recording enables data transfers that are much faster
than real time. Filed recorded to the HPX250's P2 cards have MXF
wrappers, which are compatible with all major nonlinear editing systems.
File-based recording to memory cards allows for high-speed starts,
recording starts with no need for cueing, and protection against
accidental data overwriting
- Variable Frame Rates, Even in 1080p
- Like the popular VariCam line of professional camcorders, the
HPX250 features variable frame rate (VFR) "overcranked" and
"undercranked" recording to at wide variety of frame rates (see
Specifications for details). The result is cinematic slow-motion and
quick-motion effects of the type used widely in TV commercials and
cinematic productions
- Clip Thumbnail Display & Clip Editing
- Recorded clips are automatically allocated a thumbnail image and
metadata. This lets you display a visual representation of the clip on
the LCD, delete clips, and confirm or edit metadata (using the built-in
Software Keyboard function). You can delete the last clip with a single
touch, also with a single button press, and check the beginning and
ending of the most recently recorded clip
- Shot Market & Text Memo
- Clips can be marked during or after recording. When mounted to a
PC using the downloadable P2 Viewer Windows application, the user can
view only marked clips if desires. Text memos can be posted to any scene
of a clip (up to 100 in all) for a digital version of "sticky" notes
- One-Clip Rec Mode
- Record up to 99 cuts as a single file in One-Clip Rec mode. A
text memo is automatically attached at each start-record point, making
it easy to find desired cuts within the clip once you're in the edit
suite working with a single, unified file
- Other Recording Modes
- Loop Rec repeatedly re-records a particular recurring time slot,
always maintaining a recording of the most recent period. Pre-Rec
continuously stores in standby mode up to 3 seconds of HD video (or 7
seconds of SD), and this pre-record cache is only recorded to the P2
card once you press Record. This helps you get the shot every time, even
if you "miss" the crucial moment by a couple seconds. Interval Rec
gives you automatic intermittent recording based on a set interval and
recording time. One-Shot Rec captures a single frame � useful for
animations. Time Stamp appends the date and time onto recorded images,
which is a crucial feature for evidential images
- Multi-Camera Synchronization
- The AG-HPX250 features every capability you'd want for
synchronizing more than one camera for multi-camera shoots: SMPTE time
code generator/reader, time code input and output, and genlock input
- Video Outputs: SDI, HDMI & More
- SDI output in HD and SD allows camera-through output during
HD/SD recording, or outputs high-quality 10-bit, 4:2:2 images for
playback of AVC-Intra footage. As you'd expect, SDI output includes
embedded audio and supports Record Stop/Start linked backup recording
with a Panasonic recorder equipped with HD-SDI input. When outputting
SD-SDI down-converted from an HD source, Aspect Ratio Conversion mode
can also be selected. In addition, the HPX250 gives you HDMI output for
live monitoring and for playback on compatible HDTV screens, as well as
SD composite output that downconverts recorded HD files
- Other Interfaces
- Both "host" and "device" USB 2.0 connections are included on the
HPX250, so you can offload data to a laptop or P2 deck or directly to
and from a hard drive. On the LCD monitor, you can even view thumbnails
of P2 files saved to the external hard drive. In addition, the FireWire
(IEEE 1394) port enables you to input or output a DVCPRO (including
DVCPRO HD) or DV stream. There's a camera remote input for controlling
focus, iris, zoom, and REC stop/start, and two-channel XLR audio
mic/line inputs supporting 48V phantom power
- Stylishly Designed for Mobility
- The compact, stylish HPX250 has a similar form factor to the
popular HVX200, but the handle grip and LCD position are shifted forward
to effect and overall better weight balance for the camcorder,
improving the visibility of the screen and enabling you to shoot
comfortably for longer periods of time. The HPX250 chassis is composed
of die-cast magnesium alloy for rugged durability
- High-Resolution, High-Brightness Color Viewfinder & LCD
- The AG-HPX250's color electronic viewfinder uses a 0.45",
1,226,000-dot equivalent (852 x 480 x 3 [RGB]) LCoS (liquid crystal on
silicon) display panel. It delivers bright, detailed, high-res images
and a high response speed. The camcorder's 3.45" LCD monitor has is an
approximately 921,000-dot (1920 x 480) high-resolution panel
- Low-Angle Shots
- On the upper part of the handle grip you'll find both the Rec
Start/Stop button and a lens zoom speed control (three speed levels).
This assures easy, comfortable shooting at low angles
- LCD Monitor Mirror Mode
- The LCD monitor's mirror mode is extremely convenient for shooting interviews
- Workflow Versatility
- The Panasonic P2 family includes many decks and mobile storage
units, providing a wealth of options for offloading, field editing, and
cutting back in the edit room. In addition, the file-based nature of the
HPX250's acquisition enables recorded video to be integrated into
IT-based infrastructure, for unlimited options for sharing and
distributing P2 content
- White Balance Functions
- The camera features two values (A/B) for white balance memory
and one preset value. There's also an ATW (auto tracing white balance)
function
- Zebra
- Select any two zebra levels from 50% to 100% (in 1% steps)
- Y-GET Brightness Check
- The camera's Y-GET function measures the brightness at the screen center and displays precise numerical data
- Tally Lamps
- Tally lamps are provided on the front and rear of the HPX250
