Variable frame rate
This  camera/VTR  enables  the  frame  rate  (shooting
speed) to be set from 4 frames/sec. (3.99 Hz) to 60
frames/sec. (59.94 Hz).
Since the 720P/59.94 Hz format is used for recording
onto  the  tape  or  outputting  to  the  HD  SDI  OUT
connector, users now have the exciting opportunity to
create a whole new dimension of moving images with
clearer slow-motion images and blur effects—a world
which  was  hitherto  confined  to  the  field  of  film
production—in their own video productions.
This  unit  automatically  stores  as  the  tape
management  information  both  the  frame  rate
information which indicates the shooting speed and
the active frame information which indicates the first
frame  where  the  frame  image  was  switched  in  the
user’s bit of the sub-code track area (this used to be
the LTC area).  This information is output from the TC
OUT connector and HD SDI OUT connector.  Further,
the  active  frame  information  is  stored  in  the  least
significant digit of the user’s bit while the frame rate
information is stored in its lower third and fourth digits.
Setting the frame rate

In  this  unit,  the  frame  rate  is  set  by  changing  the
storage time of the optical signals sensed by the CCD.
Depending  on  the  frame  rate  setting,  the  following
problems may arise.
1
White streaks
The dark current of the photodiode that configures
the CCD’s pixels causes defective pixels to arise,
and this results in the appearance of white streaks
on  the  screen.    This  current  increases  in  direct
proportion to the rise in the CCD’s temperature and
storage time in the photodiode.
In  short,  the  white  streaks  increase  in  inverse
proportion to the frame rate setting.
When a lower frame rate setting is desired, reduce
the master gain setting and, where possible, avoid
direct  sunlight  and  use  the  unit  in  a  cool
environment.
2
Delayed response time in automatic processing
When the frame rate setting has been lowered, it
takes longer for the unit to perform the automatic
processing  (such  as  auto  white  balance,  flare
compensation, auto knee and auto iris), possibly
giving  the  user  the  impression  that  something  is
odd or wrong.
The  response  time  for  automatic  processes  is
particularly slow at a frame rate of 20 frames/sec.
(19.98 Hz) and below.  
When  the  frame  rate  has  been  set  to  20
frames/sec. (19.98 Hz) or below, it is recommended
that  the  unit  be  operated  with  the  automatic
processing released.
3
Black shading/white shading
Both  black  shading  and  white  shading  are
compensated for when the frame rate is set to 60
frames/sec. (59.94 Hz) and scan reverse is set to
OFF.    No  compensation  is  provided  at  any  other
settings.
4
Disturbed images
The  images  may  be  disturbed  for  a  moment  if
scene-to-scene  continuity  is  performed  while  the
time  code  is  allowed  to  advance  in  the  rec  run
mode when the frame rate is set to 24 frames/sec.
(23.98 Hz).
This occurs in order to reset the video signals from
the camera so as to maintain the continuity of the
time code recorded on the tape.
The disturbed images are not recorded on the tape
but they will affect the signals which are output from
the HD SDI OUT connector.
Furthermore, if the time code is allowed to advance
in the free run mode when the frame rate is set to
24 frames/sec. (23.98 Hz), at that instant when the
time code is preset or the time code is locked to the
external signal, the images may be disturbed for a
moment.

							xx:xx:24:00
This  unit  automatically  stores  as  the  tape
management  information  both  the  frame  rate
information which indicates the shooting speed and
the active frame information which indicates the first
frame where the frame image was switched in the
user’s bit of the sub-code track area (this used to be
the LTC area).  This information is output from the
TC  OUT  connector  and  HD  SDI  OUT  connector.
Further, the active frame information is stored in the
least significant digit of the user’s bit while the frame
rate information is stored in its lower third and fourth
digits.
Example of display

OWhen  “DATE,”  “TCG”  or  “USER”  has  been
selected  as  the  UB  MODE  item  setting  on  the
TC/UB screen, the tape management information
is  output  from  the  least  significant  digit  to  the
lower  fourth  digit  of  the  user’s  bit,  so  no  other
user’s bit information will be output.
OThe tape management information is not output
as the user’s bit information in the VIDEO AUX
area (this used to be the VITC area).
57
Setting the time data
When  the  user’s  bit  and  time  code  are  both  to  be
used, the user’s bit is set first.
If the time code is set first, the time code generator
will stop while the user’s bit is being set so that the
time code setting will be off.
The time code setting range extends from 00:00:00:00
to 23:59:59:29.
Setting  the  user’s  bit  enables  information  such  as
memos (dates, times) up to 8 digits in hexadecimal
notation to be recorded on the sub code track.
User’s bit memory function
The user’s bit settings (except for the actual time) are
automatically saved in the memory and retained even
after the power is turned off.

OWhen DATE is selected from the UB MODE items,
the real time operations for year/month/day/time of
the TIME/DATE screen are adhered to. 
OWhen TIME is selected from the UB MODE items,
the real time operations for hours/minutes/seconds
of the TIME/DATE screen are adhered to.

When the frame rate is set to 24 frames/sec. (23.98
Hz), this unit will perform the processing in the non-
drop frame mode in order to maintain the continuity of
the frames even when the time code has been set to
the drop frame mode.  Furthermore, when the frame
rate has been set to 24 frames/sec. (23.98 Hz), it will
not be possible to set the time code while recording is
in progress since the images will be disturbed if the
advancing of the time code is discontinuous. 
						

							59
Externally locking the time code
1Set the POWER switch to ON.
2Set the TCG switch to F-RUN.
3Set the DISPLAY switch to TC.
4Supply  the  reference  time  code  and  reference
video signal which are in a phase relationship that
satisfies  the  time  code  standard  to  the  TC  IN
connector  and  GENLOCK  IN  connector
respectively.The built-in time code generator is now locked to the
reference time code.
About  10  seconds  after  locking,  the  external  lock
status will be retained even if the connection of the
externally  supplied  reference  time  code  is
disconnected.  However, the servo lock will be subject
to  disturbances  if  it  is  connected  or  disconnected
during recording (REC).

When the external lock operation is performed, the
time code is instantly locked to the external time code,
and  the  same  value  as  the  external  code  value
appears on the counter display.
Do not set the unit to the recording mode during the
few  seconds  it  takes  for  the  sync  generator  to
stabilize.
User’s bit setting when the time code is externally
locked
When the time code is externally locked, only the time
data  is  locked  to  the  time  data  of  the  external  time
code.
This means that the user’s bit can be set separately
for each unit.
The user’s bit can also be locked to the user’s bit of
the  external  time  code.    For  details,  consult  your
dealer.
To release the external lock
First stop supplying the external time code, and set
the TCG switch to R-RUN.
When switching the power from the battery to an
external  power  supply  while  the  time  code  is
externally locked
In  order  to  ensure  the  continuity  of  the  time  code
generator’s power, connect the external power supply
to the DC IN connector, and then remove the battery
pack.    If  the  battery  pack  is  removed  first,  no
guarantees  can  be  made  for  the  continuity  of  the
external locking of the time code.
Gen-locking  of  the  camera  unit  while  the  time
code is externally locked
While the time code is externally locked, the camera
unit is gen-locked by the reference video signal which
is supplied to the GEN LOCK IN connector.
