A:Answer I've slowed a few videos down and it does look "chunky" at best, not smooth. Also, Many people report, myself included, that shooting in 4K @ 60FPS will cause this unit to overheat pretty quickly ... five minutes, maybe. The longer you record in that setting, the hotter this thing gets. I literally couldn't touch this unit until it cooled down. I'm too afraid to use it with a tripod, fearing damage, loss of content, or even a fire in a short time.
