Your smartphone may have HD video capabilities, but if the picture is shaky or the sound muffled, you’re not getting the best that it can do. Here are a few tips to give you more professional results:
Use a tripod and get a smartphone tripod adapter. Several are on the market. They cradle the phone and have a threaded hole on the bottom for the tripod to screw into. Some systems include a small tabletop tripod.
Plug an external microphone into the earphone jack. Yes, on some smartphones this connector doubles as a mike input. You can use a wireless microphone system, or a wired mike. Usually a small clip-on lavaliere mike can work best. Bluetooth wireless mikes are available, we use this Sony professional wireless mike system.
