The time lapse feature: The play back speed is determined by the setting of time between exposures, the longer the time between frames taken the faster it plays. You can't play in real time as there is not any images or data between the frames. Some players will let you adjust the frame speed, just remember that below 18 FPS it become a series of images not a movie.Originally Posted by JRB
(18 FPS is the silent movie frame rate, 24 FPS is the talkies movie rate, and 50 (pal) or 60 (NTSC) frames rates for TV)
