1-1 Features
Chapter 1 Overview
The DNW-A25WS/A25WSP is a
digital portable editing recorder for the
Betacam SX format. It is equipped
with a color LCD monitor and speaker
to enable editing of news material in
the field.
The features of this unit include the
following.
Betacam SX format
This unit supports the Betacam SX
format, developed by Sony as the
digital version of the Betacam SP
format. No format conversion is
needed for use with nonlinear editing
systems and server systems.
Playback compatibility with
Betacam SP
It can play tapes recorded in the
Betacam and Betacam SP formats,
allowing you to make effective use of
Betacam and Betacam SP cassettes
recorded in the past. You can
assemble news gathering systems that
combine this unit with conventional
Betacam SP camcorders.
Digital signal processing
This unit processes 4:2:2 component
digital signals in the D-1 format.
Inter-frame data compression
Inter-frame data compression by
MPEG2 4:2:2 Profile @ Main Level
(1 GOP = 2 frames) reduces the
volume of data to about 1/10.
Rich variety of input and
output signals
The following input and output signals
are supported.
• SDI (serial digital interface) video
and audio
• Analog composite video
• Analog audio
• Timecode
Powerful editing functions
Combining two DNW-A25WS/
A25WSP units allows you to perform
assemble editing, insert editing, and
audio split editing. DMC (dynamic
motion control) is possible when both
the source and recording sides use the
Betacam SX format.
This unit can also be connected to a
BVE series or other editor for remote
editing.
Sequential recording
Combining two DNW-A25WS/
A25WSP units allows you to perform
sequential recording from one unit to
another.
When you perform overwrite
recording using only two cassettes, the
last two hours recording can be
obtained at any time. When you
renew the cassette about every 1 hour,
endless recording is possible.

1-1 Features
1-2 Overview
Chapter 1 Overview
525 or 625 versatility
When using the Betacam SX format,
525 or 625 mode recording and
playback can be selected from a menu.
When using the Betacam and Betacam
SP formats, only simple viewing is
possible for tapes recorded in different
mode.
Combination of two units
Using the BKNW-225 to combine two
DNW-A25WS/A25WSP units gives
you a portable editor.
Economical
• Betacam SP cassettes and
inexpensive UVW cassettes can be
used in addition to Betacam SX
cassettes.
• Special high-durability heads and
components contribute to reduced
maintenance costs.
Compact and lightweight
Even though it is a standalone editing
recorder equipped with an LCD
monitor and a speaker, thanks to its
compact design and light weight, you
can carry it easily.
Switchable aspect ratio
You can switch the aspect ratio of
video signals displayed on the LCD
monitor between 16: 9 (edge crop
mode), 16: 9 (letter box mode) and
4: 3.
Good Shot marks/Shot Data
During tape rewinds, this unit reads
the REC Start (RS) and Good Shot
(GS) marks recorded by Betacam SX
camcorders, and builds an index. The
index facilitates quick cue-ups of
desired marks (index search function),
for greater editing efficiency.
When shot marks are recorded on the
tape, you can display and sort lists of
the shot marks.
Preread editing
You can execute preread editing,
using video or audio signals recorded
on the tape as the edit source for insert
editing. Using this function, the
previously read signals ca be sent to
mixers for mixing and returned to the
original channels.
AC and DC power
This unit is equipped with V-shoe
attachment, on which BP-L60A/L90A
or BP-90A battery or an AC adaptor
can be mounted. The unit can operate
for about 80 minutes with BP-L90A
battery mounted. For AC operation,
you can connect an AC-550/550CE or
AC-DN2B adaptor.
