Relation between the number of frames shot and number of playback frames (Basic
concept 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, transfer from the
camera to the unit is at 60P for the signal of 50
frames (50 FPS) from the camera, so the
Format: S59P (23PsF) SELECT FPS = ON

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 to an
SRMemory card. When the recorded file is
played back at 24P, a slow motion effect of 0.48
times normal playback speed is obtained.
