❚❚ Slow-Motion Movies
To record silent slow-motion movies, select a “slow-motion”
option for Frame size/frame rate. Slow-motion movies are
recorded at 4 or 5 times the rated speed and play back at the
rated speed. Movies shot at 1920× 1080; 30p ×4 (slow-
motion), for example, are recorded at a frame rate of roughly
120fps and play back at around 30fps, meaning that 10 seconds
recording produces about 40 seconds of footage.
Recording and playback speeds are shown below.
