I'm really starting to get a bit disgusted with this Ninja 2. Bad enough I can't record at 24fps with it. Now I'm getting this strange behavior. It's happened both times I've used it extensively (more than 1 or 2 test shots). Both times I've had fully charged batteries. And it happens randomly, then stops. I'm including a screen shot. Notice the white box that says "20s". It count's down from 30, seconds, I presume, and then disappears. It's hard coded into the video, I can't get rid of it.
Any Ninja 2 users out there who know what's causing this? Here's the graphic:
