Depending upon the number of files falling within 1 second the resulting frame rate varies from 4 fps (0.25 seconds per each frame) to 0.25 fps for the last two frames, where files for intermediate seconds (34:21 through 35:12 and 35:14) were missing.

The real time interval of the animation does not include ascending and encloses the interval from 12:34:01 to 12:35:15. Count of files (and respectively the fps rate) and their timestamps in the local mean solar time on April 30, 2021 (sol 69 of the Perseverance rover mission) are as follows:

12:34:01 (1 fps) 12:34:02 (3 fps) 12:34:03 (3 fps) 12:34:04 (3 fps) 12:34:05 (4 fps) 12:34:06 (3 fps) 12:34:07 (3 fps) 12:34:08 (3 fps) 12:34:09 (3 fps) 12:34:10 (3 fps) 12:34:11 (3 fps) 12:34:12 (3 fps) 12:34:13 (3 fps) 12:34:14 (3 fps) 12:34:15 (4 fps) 12:34:16 (3 fps) 12:34:17 (3 fps) 12:34:18 (3 fps) 12:34:19 (3 fps) 12:34:20 (3 fps) 12:35:13 (one frame after 53 seconds missing) 12:35:15 (0.5 fps; a frame for 35:14 missing)

Timestamp for the last photo is 12:35:15, when Ingenuity has already landed at the Wright Brothers Field („Airfield A”).

The NAV camera is mounted in the helicopter’s fuselage and points directly downward to track the ground during flight.
