Sony XDCAM EX PMW-EX3 Opuscolo e specifiche

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.
