4K is the magic word that is used in the "Hero3 Black Edition". The focus is on the 4K resolution, which is equivalent to a horizontal resolution of up to 4096 pixels and is used in digital television and cinema productions.

For comparison: YouTube currently allows 2048x1536 pixels as the highest resolution, so the new GoPro can offer twice the resolution. However, what slows down this pixel rush on the new "Black Edition" is the frame rate of 12 fps (frames per second) at said 4K resolution. The human brain perceives successive images from around 14 to 16 frames per second as an apparently moving scene, which means that the camera will perform better when recording at a lower resolution but with a higher frame rate. Numerous other resolution/frame rate combinations such as 1080p-60, 720p-120, WVGA-240, 960p-100 or 1440p-48 or 2.7kp-24 are also available.

Compact and lighter
In addition to the high-resolution image format, the new model boasts other innovations: The housing has a more compact design and the weight has been reduced by 25 percent compared to its predecessor at around 80 grams (without housing). Due to the smaller dimensions, there is now only space for micro SD memory cards.

The more cost-effective "White Edition" and "Silver Edition" versions share the built-in Wi-Fi function with the top-of-the-range device, which means that Wi-Fi BacPacs no longer need to be installed to stream recordings directly to an external device. The wireless remote control is not included with the two cheaper versions and the resolutions offered are lower in each case. The adapters for attaching the camera to handlebars, helmets or frame tubes remain identical to the previous cameras.
