It's a long read and it isn't my own words, but since it pertains to a lot of peoples feelings about Destiny being at 30, here's a lot of facts for you non-believers. More of this article is below in my other post. Also found http://www.overclock.net/a/the-truth-about-fps [quote]Let's start with handling where some of these numbers actually came from. Where does the magic 24 FPS in film come from? The actual number comes from the average of 22 and 26 FPS, which were the common frame rates of silent film era. Earlier silent films had no set frame rate and often varied during recording due to hand cranks. Unfortunately, when sound was introduced in 1926, variations in frame rate altered the audio frequencies. Humans are actually more sensitive to frequency changes of audio than frame rate variations. So the industry came together and a static 24 FPS was agreed upon as the standard for film to maintain a steady video and audio experience. Believe it or not though, at the time both 24 FPS and 48 FPS were already possible in film. In 1926! Now the reason they went with 24 FPS vs. the 48 FPS using the two shutter trick, is simple: it was cheaper. People also seemed comfortable viewing 24 FPS as much as 48 FPS, so they made a business decision to save money, despite Thomas Edison recommending higher. Edison recommended 48 FPS to be more enjoyable primarily because it had better fluidity in motion and a reduction in eye strain... so science. Watching something at an unnatural frame rate, too high or too low forces us to focus harder. This induces eye strain, eye fatigue, facial muscle fatigue, and general discomfort. We simply "can't get into" whatever is on the screen. Now think about watching this screen. You probably have a nice focused concentration on your monitor with relaxed forehead and jaw. Your setup probably allows for this "extended visual concentration". You probably just now realized you have been staring at your monitor for the last 3 sentences and are now conscious you haven't blinked in a while. You’re welcome. It truly is easier for you to relax at a higher frame rate (as long as you break your 24 FPS conditioning first.) There is another "special" feature about having 24 FPS. Through surveys conducted at the time 24 FPS was the absolute minimum for a human being to perceive motion as seamless. As technology progressed 48 FPS became cheaper and even 72 FPS became feasible, 24 FPS is simply what society was used to. People both are resistant to change and there is an "adaptation" period to get used to a higher frame rate of film. Certain modern day directors, Cameron and Jackson, have experimented with 60 FPS and even 48 FPS respectively (who should be commended for that too). However, weren't fully well received. The truth still though is we are not biologically programmed to find 24 FPS more enjoyable. The reason for disagreement on enjoyment of these newer frame rates can be attributed to user's preferences yes, but mostly it is that all of us have been conditioned for decades at a slower speed of film. This has made "changing" or "updating" cinematography to a higher standard nigh impossible. The film community was very split on the Hobbit playing at 48 FPS, that is fine, but a lot of people thoroughly enjoyed it. So why not allow an option for consumers? TL;DR: 24 FPS in movies comes from about 1926, a solid number required to sync with audio. Humans are no more biologically programmed to find 24 FPS more enjoyable than 48 FPS. After 90+ years though, we are used to it. 24 FPS is also about the bare-minimum frame rate a human needs for motion to appear seamless. All about 30/60 FPS First of all this is a cool visual demonstration (as long as you have at least a 60 Hz monitor) to illustrate one way 30 fps and 60 fps visually differ to a user in real time. http://www.30vs60fps.com/ Here is another that lets you do a variety of FPS. http://frames-per-second.appspot.com/ Freeze Frame Motion: See picture above[/quote]
