-type

“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”

codec and SD recording in DVCAM format

The PMW-400 records 1920 × 1080, 1440 ×

1080, and 1280 × 720 HD images using “MPEG-

2 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.

When using UDF with a 64 GB SxS memory

card, efficient compression methods allow for

recording approximately 120 minutes of HD

images at 50 Mbps (in HD422 mode), and

approximately 180 minutes of HD images at 35

Mbps (in HQ mode). Furthermore, the PMW-400

supports recording and playback in DVCAM 25

Mbps format, as well as playback in MPEG IMX

50 Mbps format.

High-quality uncompressed audio recording

When in UDF HD422 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,

enabling easy copying, transferring, sharing, and

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.
