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.
