SR Motion (With HKSR-
102 Installed)
7-1 Overview
The SR Motion functions allow you to obtain slow and
quick motion effects in high-quality, high-resolution full
HD (1920×1080). By selecting the number of frames to
shoot (the number of frames recorded each second), you
can obtain slow and quick motion effects on playback. You
can review the motion effects immediately after shooting.
Since only the required number of frames are recorded to
tape, no format conversion is needed before playback.
SR Motion has three functions as shown below.
a) Requires the HKSR-101 as well as the HKSR-102.
See page 119 for the supported camera combinations and
the functions that are available with each combination.
Notes
• The optional HKSR-102 Picture Cache Board is
required to use SR Motion.
• Audio signals are not recorded correctly during SR
Motion recording.
• It is not possible to synchronize two or more VTRs with
each other during SR Motion recording even if you set
REGEN SOURCE in the TC Setup menu to “EXT L
(External LTC)”.
7-1-1 Overview of SR Motion
Recording/Playback
SR Motion allows you to obtain motion effects by setting
the number of frames at shooting time to a different value
than the number of frames in the recorded material
(number of frames at playback time, target frame
frequency).
Target frame frequency
Normally, the frame frequency of recorded material is set
before shooting. For example, it is usually 24 Hz for
movies, and usually 29.97 Hz or 25 Hz for TV
programming.
After shooting, when the material is played back, it is
played at that set rate. In SR Motion, the number of frames
per second in the recorded material is called the “target
frame frequency”.
SR Motion achieves motion effects by appropriately
setting three variables: the “target frame frequency”, the
“system frequency” at shooting time, and the “number of
frames shot” at shooting time.
In SR Motion shooting, you can obtain slow or quick
motion effects by recording with a system frequency or
number of frames set to a value different from the target
frame frequency. If you record with the system frequency
and the number of frames set to the same value as the target
frame frequency, normal speed video can be obtained.
