Yes, if you saw Thom's article today about the new receiver/transmitter remote, it might have some handy properties for video. Certainly start and stop. I wonder if it would allow me to change ISO when recording video in manual? Otherwise yes, I better get it together to figure out how to Smart-phone attach my D800E to control ISO without touching the camera. There is this dizzying array of wireless (attachments for the Nikon cameras right now from bottom to top of line.
"One new accessory that came up in this release is the WR-R10 wireless remote receiver and the WR-T10 remote transmitter. This device works with all 10-pin (requires WR-A10 WR adapter) or DC2 pin cameras (e.g. D3100, D3200, D5100, D5200, D7000, D300, D600, D700, D800, D3 series, and D4). It can be paired with a single or multiple cameras and has a radio-based communication distance of about 66 feet (20m). The remote can control Live View and Video operation on recent cameras (D4, D800, D600, D3200, and D5200), and can have a pre-programmed function button on it for some cameras, as well."
