The just announced (February release) GoPro firmware will add 2.7K 60p and 720 240p frame rates to the Hero 4 Black, delivering the most impressive and affordable high-frame-rate camera to the consumer market:
•3840x2160 30p 8MP capture & playback (too choppy for fast-moving subjects - running kids, sea lions, and sports in general even with lots of slow shutter induced motion blur, softening the frames)
•2704x1520 60p 4MP capture & playback (as smooth as human eyesight and sharper than 4K 30p for fast-moving subjects and panning since motion blur is not needed so the frames can remain sharp)
•1920x1080 120p 2MP capture & 60p playback (ultra smooth and sharp 1/2 speed slow motion)
•1280x720 240p capture & 60p playback (ultra smooth and sharp 1/4 speed slow motion)
GoPro sales has been increasing because the founder is a visionary who fully understands the importance of high frame rates to the fast-paced sports his users are engaging in.
GoPro users are definitely fueling the high-frame-rate revolution, and YouTube has responded to growing demands by adding 60p and 48p streaming.
The legendary filmmakers George Lucas (Disneyland Star Wars/Star Tours 60fps), Peter Jackson (Hobbits 48fps, Universal Studio King Kong 60fps), and James Cameron (Avatar 2 60fps) are all pushing the entertainment industry toward high-frame-rate contents while educating the public on the benefit of high-frame-rate capture and playback.
4K 30/24p vs. 2K 60/48p - James Cameron: "A 2K image at 48 frames per second looks as sharp as a 4K image at 24 frames per second ... with one fundamental difference: the 4K/24 image will judder miserably during a panning shot, and the 2K/48 won't." Why? 4K 30/25/24p require 1/60sec or slower shutter speeds to introduce motion blur to smooth out the panning shots and fast moving subjects which soften the image. 2K 48/50/60p will appear smooth without motion blur so the 2K frames can remain as sharp as possible even for panning shot and fast moving subjects.
Keep in mind that most filmmakers are forced to use the 80+ year old 24fps because many theaters around the world are still using 24fps film projectors. The good news is that these outdated equipments are fast being replaced by digital projectors capable of 120+fps so we'll definitely see the end of 24fps movies in the not so distance future. Furthermore, all movie studios will eventually follow Paramount lead and stop making film prints first in the US and then the rest of the world and that will accelerate the conversion to digital projectors.
After seeing Doug Trumbull's groundbreaking ShowScan presentation on the benefit of high frame rate, many in the entertainment industry have become converts. Personally, I have never shot any HD videos for family or work below 60fps - ever.
