Select Fps Function - Sony SRPC-1 Operation Manual

6-1-1 Select FPS Function

Select FPS is a function for obtaining smooth slow or
quick motion effects without skipped frames by adjusting
the number of frames shot per second. This function is
available on cameras such as F23.
The number of frames recorded in 1 second is displayed in
units of FPS (frames per second).
It can be set at steps of 1 FPS within the following range.
4:2:2 formats: 1 to 60 FPS
4:4:4 formats: 1 to 30 FPS (1 to 60 FPS when the HKSR-
103 60P Processor Board is installed.)
When installing the HKSR-103, refer to the Installation
Manual of the HKSR-103.

Relation between the number of frames
shot and the number of playback frames
(outline of Select FPS)
To obtain the desired slow or quick motion effects using
the Select FPS function, it is necessary to set the
appropriate number of frames to shoot.
If you shoot using a camera with the number of frames shot
set to 50 FPS, data is transferred from the camera to the
VTR at 60P. As a result, transferred data is padded with
frames (ineffective frames) in which no signal is recorded.
This unit extracts and stores only effective frames and
records them onto tape. When the tape is played back at
24P, a slow motion effect of 0.48 times normal playback
speed is obtained.
The following figure illustrates the operation described
above.
