The GoPro Hero4 hits the market on the 5th October, 2014, with improved image and video quality.

The most advanced GoPro waterproof camera features 4K30 video recording, 12-megapixel photos up to 30 frames per second (fps), built-in Wi-Fi and Bluetooth, and Protune for photos and video.

The GoPro Hero4 Black Edition comes with a two-times more powerful processor, two-times faster video frame rates and even better image quality than its predecessor.

Cinema-quality footage will be available with 4K video at 30 fps, 2.7K video at 50fps, and 1080p video at 120fps.

"A common pain-point is deciding between capturing video or photos of an experience. Each frame of 4K30 video is similar to an 8.3 megapixel photo," underlines Nick Woodman, founder of GoPro.

"The result is that users can simultaneously capture eye-popping 4K30 video and impressive 8.3 megapixel photo-like video stills at 30 frames per second when using Hero4 Black."

The new GoPro camera has also redesigned its audio system, and introduced improvements in image quality and low light performance.

The GoPro Hero4 Black is available for $499.99 while the GoPro Hero4 Silver can be yours for $399.99.
