image sensors
The PMW-400 Solid-State Memory Camcorder
is provided with three newly developed
"Exmor" CMOS image sensors with
approximately 207 million effective pixels, for
full HD resolution (1920 × 1080). The new image
sensor technology enables the capture of very
high-quality images, with a sensitivity of F12
(59.94i) / F13 (50i) and an S/N ratio of 60 dB by
the 3DNR function.
SxS memory cards as recording media
A new generation HD recording system
HD recording using the "MPEG-2 Long GOP,"
"XAVC Intra," or "XAVC Long GOP" codec and
SD recording in DVCAM format
The PMW-400 records 1920 × 1080, 1440 × 1080
(FAT mode only), and 1280 × 720 HD images
using "MPEG-2 Long GOP," "XAVC Intra," or
"XAVC Long GOP" codec compression. When
recording with UDF, settings of 50 Mbps (in
HD422 mode) or 35 Mbps (in HQ mode) are
supported. With FAT, settings of 35 Mbps (in HQ
mode) or 25 Mbps (in SP mode) are supported.
With exFAT, the bit rate is set to up to 112 Mbps
(XAVC-I), 50Mbps (XAVC-L50), 35Mbps
(XAVC-L35), or 25Mbps (XAVC-L25).
When using a 128 GB SxS memory card, efficient
compression methods allow for recording
approximately 120 minutes of HD images at 112
Mbps (in XAVC-I mode), approximately 240
minutes of HD images at 50 Mbps (in HD422
mode, XAVC-L50 mode), approximately 360
minutes of HD images at 35 Mbps (in HQ mode),
approximately 340 minutes of HD images at
35Mbps (XAVC-L35 mode), and approximately
440 minutes of HD images at 25Mbps (XAVC-
L25 mode). Furthermore, the PMW-400 supports
recording and playback in DVCAM 25 Mbps
format, as well as recording and playback in
MPEG IMX 50 Mbps format.
High-quality uncompressed audio recording
When in UDF HD422, exFAT/XAVC-I mode, or
exFAT/XAVC-L mode, this camcorder can
record 4-channel audio in 24-bit, 48 kHz linear
PCM format. Recording of 4-channel audio in 16-
bit, 48 kHz linear PCM format for FAT HD Mode
is possible.
Support for a file-based workflow
File-based recording in MXF and MP4 formats
allows material to be handled with great
flexibility in computer work environments,
2
/ -type
enabling easy copying, transferring, sharing, and
3
archiving.
Instant-access thumbnail display with "Expand"
function
Each time a recording is started and stopped, the
video and audio signals are recorded as one clip.
Furthermore, thumbnails are automatically
generated for each clip as a visual reference,
allowing the operator to cue-up to a desired scene
simply by guiding the cursor to a thumbnail. For
further convenience, the 'Expand' function
allows one selected clip in the Thumbnail display
to be divided into 12 equal time intervals, each
with its own thumbnail identifier. This is useful if
you wish to quickly search for a particular scene
within a lengthy clip.

Multi-format support
The camcorder supports interlace format
recording (1080/59.94i or 1080/50i), progressive
format recording (1080/29.97P, 1080/23.98P,
720/59.94P, 720/29.97P, 720/23.98P, or 1080/
25P, 720/50P, 720/25P), thus offering the
flexibility needed for worldwide HD recording.
It also supports recording and playback of SD
signals (both NTSC and PAL). The camcorder
has an optional capability to record and play back
SD signals in IMX/DVCAM format, and can
output HD signals down-converted to SD.
