A:AnswerBoth of the jacks ( mic and headphone ) are the small size 3.5 mm .After some test videos I did our first streaming video At our church yesterday using only the dynamic mic on the camera. See Vimeo.com/westsidemethodistchurch
A:AnswerYes and no. I use it to live stream to Facebook, but I have to use a video capture device, and it’s software to make the link to facebook. If you are looking for something that streams directly to Facebook live, you may look at a GoPro.
A:AnswerYes. I have it plugged into an extension cord while recording long workout sessions just to be sure I don't run down the battery and miss anything.
