XDCAM EX – A New Generation of HD Recording System
Enhanced Functionality with Exmor CMOS
In XDCAM EX camcorders, multiple A/D converters on
each pixel row convert analog signals to
digital as soon as they are generated,
unlike traditional technology that only
has one A/D converter on each chip. Exmor virtually
eliminates the influence of any external noise that enters
the signal chain during transfer to the A/D converter,
resulting in high-quality digital signals with extremely low
noise. This significantly enhances shooting in low-light
environments.

New Nonlinear Recording Media – SxS Memory
Card – For Greater Efficiency and Operability
The XDCAM EX Series adopts the SxS memory
card as its recording media. This is an ultra-
compact nonlinear medium using flash memory; and offers
a number of distinguishing features:
• Compatible with the
ExpressCard/34 standard
• Uses the PCI Express interface, and
achieves an extremely high data
transfer speed of 800 Mbps*
• Large storage capacity: up to 32-GB
memory card are available
• Most new Macintosh and PC computers are equipped
with ExpressCard slots
• Compact size: approx. 3 x 1 3/8 x 7/32 inches (75 x 34 x 5
mm) excluding projecting parts; about half the size of a
conventional PC card
• Low power consumption
In addition to the conventional SxS PRO
memory card, there is now a new member
of the SxS memory card family, the SxS-1.**
It maintains the superb usability and high-
speed transfer rate of SxS PRO card, at

an affordable price. A high-capacity SBS-32G1 (32-GB)
memory card is available.
* This data is read-speed measured with benchmark software. Actual
data transfer speeds may vary according to measurement conditions.
Please refer to http://www.sony.net/SxS-Support/ for information on
measuring methods.
** SxS-1 memory card supports fewer re-writes than SxS PRO memory
card. Notification is given when an SxS-1 memory card approaches
its end of life. Current PMW-EX1, PMW-EX3 camcorders and PMW-EX30
deck require an update (available in the Spring of 2010) to use SxS-1
memory cards.
1920 x 1080 HD Recording Using the MPEG-2
Long GOP Codec
XDCAM EX products record 1920 x
1080 HD images using the MPEG-2
Long GOP codec, which conforms to the MPEG-2
MP@HL compression standard. This highly efficient codec,
also adopted in XDCAM ® HD Series and HDV™ 1080i
Series products, enables users to record stunning-quality
HD video and audio over a long period of time thanks to
efficient data compression.
Selectable Format and Bit Rates
A choice of bit rates is offered with XDCAM EX products
– either 35 Mbps (HQ mode) or 25 Mbps (SP mode) –
depending on the desired picture quality and recording
time.
In addition to conventional 1920 x 1080 and 1280 x 720
resolutions, the PMW-350 and PMW-EX1R also offer a new
1440 x 1080 resolution in HQ mode, with interoperability at
35 Mbps between XDCAM EX and XDCAM HD systems. Clip
Browser software can very rapidly unwrap MP4 file wrappers
created by XDCAM EX products into MXF file wrappers for
XDCAM HD products without touching the MPEG2 Long
GOP codec inside these two wrappers.
SP mode supports 1440 x 1080 resolution at 25 Mbps,
providing compatibility with HDV 1080i products. Footage
recorded in SP mode can be seamlessly integrated into
HDV-compatible editing systems by connecting the
camcorder via an i.LINK* (HDV) interface. It can also be
recorded on an XDCAM HD optical disc using supplied
Clip Browser software.
* i.LINK is a trademark of Sony Corporation used only to designate
that a product contains an IEEE 1394 connector. Not all products with
an i.LINK connector will necessarily communicate with each other.
For information on compatibility, operating conditions, and proper
connection, please refer to the documentation supplied with any
device with an i.LINK connector. For information on devices that include
an i.LINK connection, please contact your nearest Sony office or
authorized dealer.
Recording and Playback in DVCAM™ Mode
(PMW-EX1R & PMW-350 Only)
In addition to HD mode, the PMW-EX1R
and PMW-350* support SD recording
and playback in DVCAM mode. This is extremely useful
for those currently using an SD production system who
need a smooth migration path to a future HD production
system. An AVI Type 2 file is recorded, which is a highly
interoperable file format for nonlinear editing systems.
* The PMW-350 requires an optional hardware key, CBK-DV01.
