Using your action camera 4K Ultra HD is easy! All you need to do is make sure the battery is charged and insert a memory card into the camera. Then power on the camera, select your desired video resolution (4K Ultra HD) in the settings menu and press record. To take photos simply switch to photo mode and press shutter release button. You can also use accessories such as mounts, tripods, or gimbals for better stability during recording or shooting from different angles. Finally, when you're done recording connect your camera to a computer via USB cable then transfer all of your files onto it for further editing if needed.
