Blur Busters Browser tests have shown Chrome, Internet Explorer 10+ and FireFox 25+ all are able to 120fps video in real-time on 120 Hz computer monitors! (H.264 format)
This is real-time 120fps High Frame Rate (HFR). This is not slow motion!
You must be using a 120Hz monitor and a recent graphics card (GPU) to view this video at full frame rate. Requires Chrome, FireFox 24+, or IE 10+.
Cameras capable of 120fps can be obtained for under $200, including Casio EX-FC200S. A better model is GoPro Hero 3, which can capture 120fps in high definition 1280x720p! Other 120fps cameras include Casio EX-F1, Fuji HS10, Nikon 1 J1. Some smartphones including Samsung Galaxy S4 and the iPhone 5S can capture 120fps, too.
How Was 120fps HFR Video Prepared For The Web?
This video was created by using a camera with a 120fps slow-motion feature. Most 120fps cameras capture 120fps for slow-motion (30fps). To make video files play in real time, you need a tool such as ffmpeg to speed up the 1/4 rate slow-motion into real-time 120fps:
ffmpeg -i slowmo120.mp4 -r 120 -vf "setpts=(1/4)*PTS" -an realtime120.mp4
Video can be embedded into web pages via the standard HTML5 <canvas> element. Most web browsers running on a fast GPU-accelerated platform (GeForce GTX 680 tested) already manage to play this video back at a full 120 frames per second in real time!
For a 1080p video at 120 frames per second, that can also play within web browsers, see World’s First Embedded 120fps Video Game Recording.
