Relation Between The Number Of Frames Shot And The Frame Interval (Outline Of Interval Frame) - Sony SRW-9000 Operation Manual

Relation Between the Number of Frames Shot and the Frame interval
(Outline of Interval Frame)
To obtain the desired slow or quick motion effects using the Interval Frame function, you need to set the
appropriate frame interval according to the number of frames shot.
When the camera has shot the material in 24P format (at 24 FPS, or in other words at a system frequency
of 24 frames), and you set the frame interval to 6FRM, then a frame is extracted once every 6th frame
from the 24 frames of video signals shot by the camera. In other words, 4 frames of video signals are
extracted every second and recorded onto tape.
When the signals are played back at 24PsF, a quick motion effect of 6 times normal playback speed is
obtained.
The following figure illustrates the operation described above.
