XDCAM EX-A New Generation of HD Recording System
Long Recording Time
Combining the moderate bit rates produced by efficient
MPEG-2 Long GOP compression and a large-capacity SxS
memory card, XDCAM EX products record high-quality HD
images for a long recording time of up to 140 minutes on a
single 32-GB SxS memory card in SP mode.
When a clip spans two cards, the transition is seamless,
without any artifacts or frame loss. The SxS memory card
can be hot-swapped while shooting, without interrupting
the recording. This feature makes XDCAM EX products
ideal for a wide variety of long-form content-production
applications.

SP mode, 25 Mbps CBR
(on 32-GB memory card)

* When recording in HQ (35 Mbps) mode, actual recording times may
vary according to the bit rate adopted during VBR encoding.
Multiple-format Recording: 1080/720 and
Interlace/Progressive Switchable Operation
XDCAM EX products offer a wide array of recording
formats for multiple content-creation applications.
Recording mode is switchable between 1920 x 1080, 1280
x 720, and 1440 x 1080 resolutions. The scanning system
is also selectable from interlace and progressive, such as
59.94i, 50i, 59.94p, and 50p.
In addition, XDCAM EX camcorders* offer native 23.98p
progressive recording in 1920x1080 and 1280x720 modes,
while the XDCAM EX deck** offers 23.98p in 1920x1080
mode.
The PMW-EX30 supports the Record function in
29.97p/25p/23.98p mode and the EE/PB function in
29.97PsF/25PsF/23.98PsF mode through HD-SDI input/
output.** XDCAM EX camcorders do not support a PB
function, but do support an EE function in 23.98PsF mode.
An SxS memory card can simultaneously hold a mix of
multiple files in any of these recording formats, including
DVCAM files – a new capability of PMW-350 and PMW-EX1R
camcorders only – allowing flexible memory card use.***
* Images are handled on XDCAM EX camcorders as 23.98p, and
recorded as 59.94i signals via 2-3 pull-down in 1440x1080/23.98p (SP)
mode.
** An early version of the PMW-EX30 requires upgrade to achieve these
capabilities. Please contact your local Sony service representative for
further details.
*** Memory card with material recorded by PMW-350 or PMW-EX1R
camcorders in HQ 1440x1080 or DVCAM mode cannot be read by
current PMW-EX1, PMW-EX3 camcorders and PMW-EX30 deck.

High-quality Uncompressed Audio Recording
XDCAM EX products support high-quality, two-channel, 16-bit,
48-kHz linear PCM uncompressed audio. In addition, the
PMW-350 camcorder records four-channel audio and, when
this is replayed from the memory card by other XDCAM EX
products, the user must select from CH-1/2 or CH-3/4.
High Reliability Memory
SxS memory cards resists considerable shock (1500 G) and
vibration (15 G). Adopting this memory recording system,
the unit's mechanism is simplified. Also, a unique Salvage
function serves to restore content that is damaged by
power loss or memory disconnection during recording.*
* In some cases, images recorded just before an accident may not
be restored (four seconds maximum). No warranty is given on always
achieving content restoration.

IT Friendly
With XDCAM EX products, recordings are made as data
files in ISO-standardized MP4 format. File-based recording
allows material to be handled with great flexibility in an
IT-based environment for copying, transferring, sharing,
and archiving. These operations are accomplished without
loss, and without any re-digitizing process.
The recording system also allows for material to be viewed
directly on a Macintosh or PC – the user simply inserts the
SxS memory card into a computer's ExpressCard slot and
uses the supplied Clip Browser Version 2.6 and compatible
nonlinear editing software, to view, edit, and search
metadata. This helps to improve workflow efficiency.
Acquisition Metadata (HD mode only)
As part of a variety of metadata such as shooting Date/
Time, OK status, Title, Shooter name, Description and
Essence Mark, XDCAM EX camcorders have a unique
capability of recording camera parameters onto the
recording media while shooting - such as Focus, Zoom, Iris,
Shutter, Gain, White Balance and Gamma.
Clip Browser V2.6 allows to review these acquisition
metadata in viewing clips, which is useful as a reference
for editing process or next shooting.
