[EG] James Cameron ponders 48 or 60fps shooting of future Avatar films - Page 7

post #61 of 177
any movie that is greater than 24fps looks unnatural, since our eyes technically see that quickly. 60fps is great in games, but not in real life.

When you work with Prosumer cameras, there are shutters speeds much like in still cameras, and again much like still cameras the higher the shutter speed, the lower the motion blur.

Now when using a video camera correctly to shoot, you want the Shutter speed to be double (or some multiple of double) the frame rate. So when using camera at 24fps you'd only need a shutter speed of 1/48 seconds. So the shutter stays open pretty long getting more information and adding a more natural motion blur.

However with framerates like 60 you have to use a shutter speed of 1/120 seconds, so the shutter is open for a short time, producing a rather unnatural blur free series of frames.

So in conclusion: 24fps is actually more "natural" than 60fps.

Hope this helps!
I don't quite agree, if the motion is fast enough it does not matter, you will always get motion blur, however at higher frame rates your eyes will cause the motion blur with is what is actually natural. This is exactly how Crytek made Crysis tolerable at lower frame rates, they used motion blur that was put in intentionally to give the player the feeling of a higher frame rate, when we bring the frame rate in films up to a higher speed then instead of tricking the viewer into feeling a higher frame rate we give the viewer a higher frame rate. Everyone that has been saying they watched a higher frame rate movie and said it looked weired was not looking at a true higher frame rate, they were looking at an image that was being partially generated by a computer.

Our eyes do not "see" at 24 fps. Our eyes do not see in frames at all. That being said, an image over 100fps is noticeably more realistic than one at 60fps or 30fps.

exactly it makes it look like a home movie or like a high school video project. 24 fps has that nice motion blur that we're all used to. and i like it that way. for games 24fps is terrible though.

You talk of myths and poor reasoning right after you come flying out of the gate with this gem. I don't really know you mean here. You're saying in order to detect something, we have to see it for 125ms?

In a P-D image demo having 60 FPS or more is wanted because the human eye picks up the unnatural depiction of imagery.
As a rebuttal to sbeast's assertion that we only see at 32fps, it works perfectly well. If we were truly only able to see 32fps, then the additional frames added when rendering at 60fps would still not be seen. Funny thing is, there is a noticeable difference between the two. If we really did only see at 32fps, 60 would look no different than 32, as the intermediate frames that would smooth the animation wouldn't be seen. The increase in animation is seen because we actually do see those extra frames.

Of course people will see this, the eye captures data on-going, it does not capture a bit of data instantly, then capture nothing for awhile, then go back to capturing it.
I don't really see what you're getting at here. I feel like you're arguing for the sake of arguing. The point was that something as quick as 1/220th of a second is noticeable. Apparently you're not trying to refute that. End of story. There's nothing to argue in that case, so I don't really see the point of this part of your post. Also, I'm not seeing where you're pulling this "it does not capture a bit of data instantly, then capture nothing for awhile, then go back to capturing it" part from. I made no such claim.

No. His premise was that since fighter pilots can supposedly see a black dot when it is flashed at 1/220th of a second, humans can see at 220 fps. My argument is that his premise is junk. Humans can't see at 220 fps, or even 30.

Then explain yourself. If what you're implying is true, then there would be a point at which additional visual input wouldn't be detected because we can't see quickly enough to notice it. Clearly the additional information added when going from 30fps to 60fps isn't going to waste. Animation is smoother because we can see those extra frames. Common sense dictates that our threshold is well above 30fps.

That's not much of an argument. An argument would follow logic.
