Features
The PWS-4400 is a multi-channel recorder that is
equipped with the MPEG-4 AVC/H.264 codec and can
handle 4K to HD resolutions.
Utilizing its high-speed, large-capacity memory storage,
the unit is capable of real-time recording and playback of
high-quality video for increased efficiency in video
production applications, such as live broadcasts and studio
productions.
High-quality video and audio
recording
The unit employs XAVC format in conformance with the
MPEG-4 AVC/H.264 codec as the recording system to
obtain digital recording and playback of high-quality
video.
The unit also supports 16-ch audio (uncompressed, 24-bit,
48 kHz).
Multi-codec
XAVC or Avid DNxHD(R) codec can be selected for HD
recording and playback (when PWA-CD401 is installed).
Multi-resolution
The unit allows recording and playback of 4:2:2 (10-bit)
signals in 1280×720 (HD), 1920×1080 (HD), 2048×1080
(2K), 3840×2160 (QFHD), and 4096×2160 (4K)
resolutions.
The unit’s video compression rates are as follows.
• HD, 2K: XAVC Class 100, DNxHD145, DNxHD220x
• QFHD, 4K: XAVC Class 300
High frame rate recording
The unit can record video signals at high frame rates, in
addition to the standard frame rate.
Signals recorded at a high frame rate can be played back at
normal speed, and can also be played back as smooth slow
motion video.
The unit supports recording at the following high frame
rates.
• HD (1280×720) 100p/119p/200p/239p/300p/359p
• HD (1920×1080) 100i/119i/200i/239i/300i/359i
• HD (1920×1080) 200p/239p/300p/359p
• QFHD (3840×2160) 100p/119p
Multi-port
The unit is equipped with four input/output ports, each
capable of handling 4K and HD signals.
The input/output of each port can be switched via a
configuration menu that can be viewed in your web
browser.
You can flexibly arrange input/output into 4-input, 3-
input/1-output, 2-input/2-output, 1-input/3-output, or 4-
output configurations to suit your production needs and
environment.
Additional HD input ports
For HD, the unit supports simultaneous dual-system
recording using a single input board. This enables 4-in/2-
out and 6-in/1-out configurations.
Port sync operation
The unit can be configured for operation with synced input
ports and synced output ports.
When input ports or output ports are grouped, changing the
operation of one port also changes the other ports within
the group in unison.
