Video above has details but the headline says it all really. The GoPro Hero 5 Black’s HDMI port spits out clean UHD / 4K when in Live mode. For such a small camera, this is completely nuts. Will take a look at the actual signal tomorrow but as far as my AJA HA5-4K and Convergent Design 7Q are concerned this GoPro lives up to it’s hero moniker.

Thanks to the guys at Back Bone (GoPro modifications) for bringing this to my attention. As far as I can tell this is an undocumented feature – it doesn’t appear on the spec pages or user manual for the GoPro Hero 5 Black.

I might be missing something – so prepare to be disappointed – but the AJA input (image below; blue writing, top left) reads 3840 x 2160P 29.97FPS, RGB 4:4:4 at 24 bits per pixel (8 bit colour) from the GoPro HDMI port. My Convergent Design 7Q is setup to accept 4:2:2 YCbCr, so that explains the discrepancy in numbers in the Instagram video shown above.

Anyway, will do some test recording ASAP, run the footage through Resolve, and update this blog post in a few days.
