Frame frequency group
50Hz
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
The unit can 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.
HDSDI remote recording
HDSDI connections can be made to camcorders with
remote HDSDI support (PDW-700 XDCAM HD422
camcorder, HDW-730/730S/750/790/F900R HDCAM
camcorders) to enable recording synchronized to REC and
STOP operations on the camcorder.
1) HDCAM is a trademark of Sony Corporation.
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).
Note
This function is available only when you are operating
equipment connected to the REMOTE(9P) or SD/HDSDI
INPUT connector. It is not available on the front panel.
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

High-speed searches with the jog and shuttle
dials
The jog and shuttle dials can be used to find scenes inside
clips, in the same way as the jog and shuttle dials on
conventional VTRs.
In jog and variable modes, you can search in field units at
from –1 to +1 times normal speed. In shuttle mode, you
can perform high-speed searches at either ±20 times
normal speed or maximum speed (as selected by an
extended menu setting). High-speed F.FWD and F.REV
searching is possible at either ±30 times normal speed or
maximum 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.
Filter Clips function
You can select clips of a certain type from among all of the
clips on a disc. For example, you can do the following.
• Select clips in a certain video format from a disc that
contains clips in different video formats.
• Select only clips with NG (bad) clip flags, and delete all
of those clips in one operation.
• Select only clips that were recorded according to
planning metadata, and use the Direct FTP function to
transfer those clips to an external device.
