Question about Insta360 GO 3 64 GB

Video (Full HD, 50fps) = 3 hours 4 minutes
Video (2.7k, 30fps) = 2 hours 35 minutes
Photos = 3074

Info according to test report of a photo/video magazine

It depends on which mode you film in.

In normal video mode: approx. 1h 59min
In Timelapse mode: approx. 9h 30min
In Freeframe mode: approx. 1h 30min

So quite different... But in most cases it is sufficient if you export the videos and then delete them.

Correggo: 2,7K

It obviously depends on the format chosen (2K, HD ...).
I have never checked the actual capacity, however I believe that the capacity exceeds the battery life even in 2K.
