"One VERY important detail (and maybe a deal-breaker for some users like me that want to shoot very long videos) is that the Insta360 creates a new clip every 30min BUT stops recording for 15 seconds before continuing on so, if you are trying to record an event that is 45 minutes, you will end up with a 15 second gap around minute 30.”
Other
editing software is more feature riched but a bit more demanding on the mobile device
