Main Features
High Quality Digital Video and Audio Recording
The DNW-75 delivers the exceptional video quality of the
Betacam SX format, recording 8-bit, 4:2:2 component
digital signals using MPEG-2 4:2:2 Profile@Main Level
compression technology. The system also includes four
16-bit, uncompressed audio channels.
±0 frame Insert/Assemble Editing
The DNW-75 enables insert and assemble editing with the
±0 frame accuracy. This enables precise editing on
Betacam SX
tape in machine-to-machine or A/B roll
configurations.
Preread Editing Capability
The DNW-75 is equipped with Preread technology, which
has proven invaluable in the Digital Betacam series VTRs.
Preread heads are located ahead of the record heads on
the drum scanner, and previously recorded video and
audio signals are read by these Preread heads. This
signal can be processed by external equipment and
recorded back onto the same track. This capability is
ideal for titling, color correction and layering for video, and
mixing or sweetening for audio.
Variable Speed Control
The range of the Variable Speed Control is from -1 to +2
times with noiseless image and digital jog sound.
DMC (Dynamic Motion Control)
Equipped with the Dynamic Motion Control functions, the
DNW-75 provides slow-motion playback from the control
panel or from external controllers such as the BVE series
editors or DTR-3000 slow motion controller.
The Digital Video Cassette Recorder—DNW-75
In the relatively short time since its launch, Betacam SX™ has provided broadcasters and production
companies with superb picture quality, outstanding operational functionality and significantly reduced
operating costs. Based on MPEG-2 4:2:2 Profile@Main Level compression strategy, the Betacam SX
format has been the foundation for a range of recorders and players supporting both non-linear and
linear video tape operations.
Previous models have provided the facility to play back analog Betacam™ and Betacam SP™
recordings. When this feature is not required, the Sony DNW-75 Digital Video Cassette Recorder can
be the ideal choice. The DNW-75 is a Betacam SX editing VTR capable of insert and assemble
editing to zero frame accuracy. It can also be used for linear operations, such as in A/B roll systems
controlled from the familiar Sony BVE edit controllers, or installed in Sony Flexicart™ and Library
Management System™ (LMS) as a multi-segment VTR.
It includes a wide range of features, including
DMC (Dynamic Motion Control), Freeze
function, 525/625 operation, variable speed
playback, Good Shot Mark support, and an
optional SDTI (Serial Data Transport
Interface) carrying MPEG data.
Note: SDTI is defined by SMPTE 305M.

Main Features
Good Shot Mark
One of the most useful features of the Betacam SX series
is the Good Shot Mark system, providing a method for
qualitative decisions made in the camcorder to be utilized
during the editing process. The DNW-75 can scan the
tapes and automatically detect shot marks recorded on
the tape. After scanning for marks, a list of all the marks is
displayed on the monitor, allowing easy cueing to any
mark. In addition, the DNW-75 has two types of the
additional marks. One can only be memorized during the
Play, Shuttle, Jog and Still, called “Virtual Shot Marks”, and
another can be recorded on the tape. These features can
speed up the edit search process dramatically.
525/60 or 625/50 Versatility
The DNW-75 can easily be switched from 525/60 to
625/50 modes. This enables the DNW-75 to work in
international environments.
Versatile Interfaces
The DNW-75 is equipped with analog composite and
component video I/O, component SDI I/O and 4 channels of
analog audio I/O, AES/EBU I/O, and 2 audio monitor outputs
as standard. In addition, RS-422A control, RS-232C control,
Parallel 50-pin remote control interface, video processor
control interface (Parallel 15-pin), and Time Code I/O are
also included. SDTI (SX) output is an optional interface.
It enables to transfer the material to an A/V Server at a
maximum of 2 times normal speed and will speed up the
editing time.
Multi-segment Recorder in the Flexicart and
LMS Systems
The DNW-75 can be used as a multi-segment recorder in
the Flexicart or LMS, giving these multicassette systems
the advantage of long playing times and lower
maintenance costs associated with
the Betacam SX format.

Long Recording & Playback Time
The DNW-75 provides long time Recording and
Playback time for 194 minutes using the L cassette and
62 minutes using the S cassette.
Flexible Usage of the Control Panel
The remote control panel of the DNW-75 can be
extended. Also, since the DNW-75 is equipped with
another connector on the rear panel, it can be controlled
from two control panels, adding greater operational
flexibility.
