Kandao Qoocam 3 Ultra

Could you verify that a shot is really created every 2 s (file creation date or so)?

Which intervals are supported in interval photo mode?

but here is a single shot

This shot looks awesome!

Did you any post-processing?
How looks horizon levelling, when the mount is not perpendicular? See New Insta360 x4 with 8k video - #12 by Hol_Ger.

I am very excited to see more of your interval photos.
