I am trying to make a hyperlapse around a big church, is there a way to calculate what the settings need to be to make it do a full circle or do I just do trial and error by adjusting speed and length?

Hi, thanks for the inquiry. Under the circle mode, you could set the interval time, video duration, and circle orientation depending on your preferences. For further details on the Mavic 2 Hyperlapse Modes' Parameters, you may refer to the details below. Thank you for continued support.

Circle: Users can set the interval time, video duration, and circle orientation.
Free: Users can set the interval time and video duration. In this mode, the aircraft can travel at a fixed speed and take photos at the same time.
CourseLock: Users can set the interval time and video duration. The user can select a subject in this mode.
Waypoint: Users can set the interval time and video duration. Users can also choose 2-5 waypoints.

The aircraft only generates a video if it has taken at least 25 photos, which is the amount required to generate a 1-second video. The video generates when a command is given from the remote controller or if the mode is exited unexpectedly (such as when the low battery level RTH is triggered).
