So the video gesture available with the new update .0500 only works when Spark is within palm control. If I send it "away" it doesn't recognize the video gesture but all others work. Edit: once palm control is established and the video has started one can then re-establish palm control and send the Spark away and it will perform normally.
That explains why it hasn't been working for me. The intuitive assumption is you that could replace with selfie gesture with the video gesture. Guess not!.
