Sometime you don't have the best line of sight down a chute, so you lose video around a corner or two. But just hold steady course and trust that video will come back. Most of these chute runs arents just first tries, it's multiple batteries of feeling out the location, scouting for scraggly branches, or pockets of video loss. Then trusting your gear, and flying your line till you get the shot you want. A good clip doesn't happen on the first take, it takes patience and repetition till you like what you got.
