RCIN zeros out, resulting in glitching

Can someone tell me what kind of problem would cause the RCIN to zero out for a moment causing the copter to drastically respond as if I mashed the sticks (0:46 and 1:00 in the video)? It did not trigger a throttle failsafe though like it probably should have. Posted this on DIYDrones but am not getting a response.
