[Huffington] The Hobbit 48 FPS Footage Divides Audience - Page 19

post #181 of 186
Getting used to higher frame-rate movies may make watching standard 24-frames per second film almost unbearable as the extra blur and strobing can cause fatigue and headaches. In any case this is a necessary upgrade for cinematography as part of producing higher quality video. Kind of how games are playable at ~30fps though people prefer the higher frame rates for enhanced smoothness.

Still the argument that movies should not appear as realistic as sports broadcasts is rather arbitrary. Movies with plenty of action would definitely benefit from the higher frame rates.

Also for people saying that human eyes see in frames, this isn't true: http://en.wikipedia.org/wiki/Frame_rate#Background
Quote:
The human eye and its brain interface, the human visual system, can process 10 to 12 separate images per second, perceiving them individually.[1] The visual cortex holds onto one image for about one-fifteenth of a second, so if another image is received during that period an illusion of continuity is created, allowing a sequence of still images to give the impression of motion. Early silent films had a frame rate from 14 to 24 FPS which was enough for the sense of motion, but it was perceived as jerky motion. By using projectors with dual- and triple-blade shutters the rate was multiplied two or three times as seen by the audience. Thomas Edison said that 46 frames per second was the minimum: "anything less will strain the eye."[2][3] In the mid- to late-1920s, the frame rate for silent films increased to about 20 to 26 FPS.[2] When sound film was first introduced in 1926, variations in film speed were no longer tolerated as the human ear was more sensitive to changes in audio frequency. From 1927 to 1930, the rate of 24 FPS became standardized for 35 mm sound film;[1] a speed of 456 millimetres (18.0 in) per second. This allowed for simple two-blade shutters to give a projected series of images at 48 per second. Many modern 35 mm film projectors use three-blade shutters to give 72 images per second—each frame flashed on screen three times.[2]

Human eyesight is based on chemistry which has no real limit to frames it can see per second. Rather it gradually blurs as the frame rate increases.

That doesn't make sense


Before you claim nonsense you should research the topic. It's really interesting on its own right. Your brain can only process so much data from your eyes. The eyes capture everything and it's really too much for the brain to take in when the scenery starts moving fast like a ride on a rollercoaster. It really doesn't take much to over tax the brain. Thus the blurring happens. About film science, 18fps then 24fps was about what the industry ended up at in terms of allowing viewers enough time to fully take in the image and another part cost because more fps means more cellulose. Anyways, it's one part historic, or that is what we've become accustomed to historically and that derived from a necessity.

It's interesting the use of blur in games these days, especially with racing games. Why is there blur in games, it seems counter to the whole pristine image perspective until we realize developers are just trying to mimic the way the brain works. Remember the image is not blurred, it's out brains.

Btw, you're making up an argument all on your own. I never said any of that nor thought it. I just stated that this is probably why many ppl feel the way they do and cannot quite place their finger on it.

Ok...I can completely get that. From your post it seemed like you were claiming 24fps was superior because it didn't overload your brain, rather then trying to explain why people are sensitive to higher rates.

Although I am still a bit mystified. It seems to me that our brains will still do the blurring as necessary for high fps content, and I feel like I would much rather have that be the case then having it done by the source itself. I have found myself becoming more sensitive to all the blur, judder and other issues that plague fast moving content shot at low fps

I don't know if you realize this, but your real world life is not one fluid scene. Unconscious to you everything is a still image much like a film. Your brain takes snap shots and when things move too fast blurring happens. Thus when it moves too fast and without natural blurring, it looks fake. In real life, the blurring helps your brains slowness to cope with the movement beyond your brains pace of digestion of info. Thus fast motion filming w/o blurring can tend to throw ppl off. About the only time it doesn't is sports.

So why don't our brains apply "natural blurring" to the film itself? I.E. - if our brains apply "natural blurring" to rapid motion "in real life," then why isn't said blurring applied to the rapid motion taking place on the movie screen? The movie screen is, in fact, a product of the real, actual world.

Speaking of vague terms - what exactly is a "brain snap shot?" This all needs to be explained with more clarity and precision, else it just sounds like boilerplate.

refer to this page, it offers information on motion blur ,and gives an example as to motion blur that exists from a biological standpoint.
http://en.wikipedia.org/wiki/Motion_blur

A movie is "a product of the real, actual world" however it is not the same as the real, actual world. Filming at 24FPS does not depict real life as accurately as a film recorded at 48FPS or higher.

In a way Peter Jackson is just taking the next step towards realism in cinema. Realism cannot be achieved until a movie can be recorded with no set restrictions such as FPS.

this is why interlaced can be so god because it is 29.97 hertz.true i wish it was 32 to be perfect but 29.97 properly adjust is very good ,the issue we ll face is 3 d to get just = of 29.97 in 3 d you ll probably need 59.94 full frame this mean you ll have 119.88 half fram or so imagine a progressive 3d you ll need 119.88 full frame minimum just to equal 60 hertz of today and recommended will probably be 239 .xx
ya it become nightmarish
