Someone asked in another one of the threads if the camera remote app on the watch allows you to record video.
It doesn't 🙁
If you switch to video on the iPhone's camera app, the watch displays a message that says "Video not supported. Switch to Photo."
I found that if I disregarded that message and hit the record button on the iPhone, the watch then displayed "Video capture in progress." with a button reading "End Video".
So you can stop a video recording with the watch app, but you can't start one.
