Here is a sample of difference with gopro nighttimelapse settings.
I had to halt the project beacause my brand new gopro hero 4 black has now broken usb-port. They are very fragile. Real letdown. And add the injury there would have been aurora borealis in the next night.
Pictures taken to iMovie. Each frame duration is set to 0,4 seconds. Project is saved as movie. Movie is loaded to new project in iMovie. Clip is used is 4x speed from original movie.
