You can record clips with different recording formats, for
example HD422 and HD420SP clips, by putting this unit
into mixed format recording mode.
Note
Continuous playback may not be possible at the transition
point between two clips with different recording formats.
SD upconvert function
This unit is provided with an upconvert function, allowing
HD recording of SDSDI signals input to the SD/HDSDI
INPUT connector and composite signals input to the
COMPOSITE IN connector. The unit can also output HD
signals while playing discs recorded as SD, allowing SD
material to be utilized in an HD environment.
HD downconvert function
The unit is provided with a downconvert function. HD disc
playback signals can be downconverted to SD signals and
then output as SDSDI or composite signals. This allows
you to use SD nonlinear editors and monitors for editing
and program output.
1080/720 cross-conversion
This unit supports cross-conversion output. It can output
720 while playing discs recorded as 1080, and output 1080
while playing discs recorded as 720.
HDSDI remote recording
HDSDI connections can be made to camcorders with
remote HDSDI support (PDW-F800/700 XDCAM HD422
camcorder, HDW-730/730S/750/790/F900R HDCAM
camcorders) to enable recording synchronized to REC and
STOP operations on the camcorder.

Clip Continuous Rec function

Normally, a clip is generated as an independent file every
time recording starts and stops. The Clip Continuous Rec
function allows you to continue recording to the same clip
until the function is stopped or turned off, regardless of
how many times recording starts and stops. This is
convenient if you want to avoid generating a large number
of short clips, or if you want to record without worrying
about the limit on the number of clips (maximum 300).
Recording of proxy AV data
Proxy AV data is a low-resolution (1.5 Mbps video, 64
kbps per audio channel), MPEG-4 based version of a full
resolution data stream. Whenever this unit records full
resolution MPEG HD422 data, it simultaneously generates

and records low-resolution proxy AV data. Because of its
small size, proxy AV data can be transferred quickly over
computer networks, easily edited in the field with laptop
computers, and readily used in a wide variety of
applications, such as content management on small-scale
servers.
High-speed searches with the shuttle/jog dial
The shuttle/jog dial can be used to find scenes inside clips,
in the same way as the shuttle and jog dials on
conventional VTRs.
In jog and variable modes, you can search in field units at
from –1 to +1 times normal speed. Shuttle mode supports
high-speed searches up to a maximum of ±20 times normal
speed.
Convenient disc-based playback and searching
Like previous products in the XDCAM series, this unit
supports a number of convenient search functions,
including scene selection, thumbnail searches, essence
marks searches, and expand searches.
Scene selection: This function allows you to select clips
from the disc and insert them into playlists. Clips can
be inserted and played back in any order.
Thumbnail searches: The unit creates thumbnails from
the first frame of each generated clip, and displays
them in thumbnail lists on the color LCD or an
external monitor. You can cue up clips very easily by
simply by selecting them from thumbnail lists.
Essence mark searches: Essence marks can be recorded
at any scene during or after recording. Lists of these
marks can be displayed on the color LCD or an
external monitor, allowing you to quickly find scenes
that were marked for later reference.
Expand searches: This function allows you to look inside
the clip selected in a thumbnail screen, or inside the
segment from a selected essence mark to the next
essence mark. The selection range is divided into 12
equal blocks, and the first frames of those blocks are
displayed as thumbnails. By checking the thumbnails,
you can easily find the scene you want.
Usability features
AC, DC, and battery power support
The unit can be used even where AC power is not
available, for example outdoors or in cars or helicopters.
Color LCD display
The unit is equipped with a 16:9, 9-inch widescreen color
LCD which allows you to check the contents of the disc
and use the menu system without connecting an external
monitor.
Waveform monitor and vectorscope
You can display a basic waveform monitor or a basic
vectorscope.
