Warning: The following video may cause motion sickness! I shot this video when I was at the Monterey Bay Aquarium with GH4 mounted to a baby stroller. It's one idea on how to use the variable framerate feature on the Panasonic GH4, but of course i'm sure you guys can do it better.
It's a fun feature to have built right into the camera since it requires no post processing. The moment you hit stop you end up with a single video file ready for playback.
