Adjustment
What is the Timing Adjustment ?
When you play back the tape which you had edited using
the program editing, the IN point and/or the OUT point may
not be the scene you had designated. Some scenes may
not appear, or some unnecessary scenes may be included.
There are several possible causes for such discrepancies:
some recorders are late to start recording, some recorders
rewind the tape at the end of recording, or some recorders
are late to enter the recording pause mode after recording.
Timing adjustment is the operation to compensate for the
lag caused by the above characteristics of the recorder so
that the Cuts are more accurately recorded from the IN point
to the OUT point as you designated. (For details of such lag,
tefer to page 26 in the operating instructions.)
The lag caused by the recorder results in an edited tape as
shown on the right.

| Why the beginning of a Cut is lost
For the program editing operations, the RM-E700/RM-ES500
transmits the control signal to the player to playback from
about 15 seconds before the IN point and to the recorder to
release the recording pause mode at the IN point. But, some
recorders require several seconds before starting recording
after the recording pause mode is released. This is why the
beginning of the Cut is lost.
Why the end of a Cut is lost. or an
unnecessary scene is included at the end
of a Cut
For the program editing and scene-by-scene editing
operations, the RM-E700/RM-E500 transmits the control
signal to the player to playback unti! about 2 seconds after
the OUT point and to the recorder to enter the recording
pause or stop mode at the OUT point. But, some recorders
require several seconds before entering the recording pause
or stop mode after recording. Or, when starting next
recording, some recorders rewind the tape a little and enter
the recording pause or stop mode. This is why the end of
the Cut is lost, or an unnecessary scene is included at the
end of the Cut.
Once the timing adjustment has been done, the RM-E700/
RM-E500 will automatically compensate for the
characteristics of the recorder to ensure that the IN and
OUT points are recorded accurately. If you use another,
different model for recording, be sure to do that timing
adjustment procedure again for that unit.
The RM-E700/RM-E500 can compensate for the lag:
at IN point — up to 5 seconds by 1/30 second (1 frame*) for
the NTSC system and by 1/25 second (1
frame*) for the PAL system
at OUT point — from -1 second to 5 seconds by 1/30 second
for the NTSC system and by 1/25 second for the
PAL system.
* Frame
One frame equals one image. However the number of frames
displayed in one second differs according to the TV system.
In the NTSC system, about 30 frames are displayed per second.
In the PAL system, 25 frames are displayed per second.
For the customer having a Sony video
cassette recorder
lf your video cassette recorder is one of the following Sony
models, the timing adjustment data is provided. Therefore,
you do not need to do the entire procedure. Use the
appropriate data and do only 4, 5 and 7 of the flowchart on
page 3. However, even if the model is same, the data may
be slightly different depending on the unit. If you want to
know the exact data, perform the entire procedure.

On the recorder
* With some recorders, the lag at the IN point of the first Cut of
the program is different from that of other Cuts of the program.
« With some recorders, the lag at the OUT point of the last Cut of
the program is different from that of other Cuts of the program.
« Perform the timing adjustment again when:
— you changed the recording mode of the recorder.
— you changed the control connection of RM-E700/RM-E500
and the recorder.
