Slow Motion Timelapse

Supports 4x or 8x slow-motion video shooting. In Slow Motion mode, the camera records the video with a high frame rate and slows the footage down to 4x or 8x the normal speed during playback. Slow Motion catches details not visible to the naked eye, which is ideal for fast-action shots. Note: slow-motion videos do not include audio. The audio file is stored as a standalone file and has the same path as the videos, which can be transferred to your computer.
Select from Hyperlapse and Timelapse. In this mode, the camera turns long events into short videos by taking a frame of video at set intervals.
Use Hyperlapse to record smooth timelapse videos when the camera is in motion (such as in a car or when held in the hand). Use Timelapse to record timelapse videos when the camera is mounted and still.
Three presets in Timelapse are designed for typical scenes such as Crowds, Clouds, and Sunset. Users can also optimize the interval and duration for recording timelapse videos.
