What is all about:
It’s about videos.
Wikipedia says: the lowest frame rate to achieve the illusion of a moving image is about fifteen frames per second . Though, there is no technological limit to shoot films at 50fps or more. So why we make and watch movies at 24fps. Main reason is that people got used to this ‘cinematic movie look’. Fortunately nowadays this is changing. Most of newer HDTVs use sophisticated technology to increase video frame rate. This technology exists to eliminate video frame juddering. Some people enjoy smoother image, some not.
On the website you can find videos which already converted to 60fps and an application which allows you to convert any video file to higher frame rate using your PC.
