Glasses-less 3D TV for $20K

[Sir Terrence the Terrible]

Hi T,

I think I get what you are saying. Films are recorded at 30 frames per second, which is not the same thing as saying that a display has a refresh rate of 30 (or 60, 120, 240...)Hz.

Actually Gman, film uses 24fps, and video sources use 30fps.

My question is, how do these correlate to each other?

Part 1) How does fps compare to Hz? Does 30 fps work out to 60, 120, 240 Hz, or is there no relationship?

There really is no relationship. Frame rates are produced by camera's, and refresh rates are used by display devices.

Part 2) Does buying a TV with 240 or 480 Hz make a difference in motion blur if the 30fps is less than those?

To be honest, 240hz and 480hz are just marketing on steroids. 120hz is really all you need in the end. Motion blur is caused by the pixels themselves, and no refresh rate will change that much. You can use video processing to mitigate motion blur and it can be quite effective if properly implemented.

Part 3) Does the recording rate affect motion blur at all, or would it just make the film look more choppy if the rate was lower?
Thanks for the info.

Yes the frame rates do effect motion blur, which is why Peter Jackson is using 48fps for the Hobbit, and James Cameron is looking to shoot Avatar 2 at 60fps. 48fps will "perceptively" eliminate blurring, but 60fps eliminates it altogether.

Can you 'spain to me the difference between film and video source? Is that analog vs digital?

Easy..Film camera's use film, and video camera's use video tape. Film has very difference visual characteristic than video tape. Color saturation is more distinct and profound with film.

Today film camara's can be digital or film based. One shoots the source and it is recorded as a series of 0 and 1 and stored on a hard drive or server. The other stores the visual source on film that a lab develops into prints.

GOD, what an ignoramus.
"FILM" cameras use just that ...film. This is some kind of emulsion, and is basically what EDISON invented.
Digital is VIDEO, there is NO such thing as "digital" film, all digital
is recorded on either a hard drive, tape, or some kind of memory.
THERE is NO such thing as "digital" film, there is however digital VIDEO.
and color saturation, etc, while good with film, is also good with video of decent quality. Sometimes you can't tell the difference between HD VIDEO and film, even experts are fooled
sometimes. NON EXPERTS like TALKY are fooled all of the time.

OK, so film camera's are for pro use, while video is for commercial or personal use?

No, you can use a film camera if you like, anyone can if you can afford them. The professionals are switching from film camera's to digital camera's these days. Cheaper to buy, easier to use, and you don't have to pay for film processing.

Just trying to understand the difference(s) between film camera's that use film, and video camera's that use video tape? If pros switch from film to video, will than mean that they will be using 24fps?

Currently they are sticking with 24fps for digital video. It is the standard in Hollywood production and post production. As Jackson and Cameron up the ante on frame rates, we'll see how that affects consumer video formats.

HE CAN'T "spain" what he doesnt understand.

ONE MORE THING, all film is analog, but not all video is digital.
Video used to be analog exclusively, and lagged a great deal
behind film. YOU COULD TELL THE DIFF between tv shot on film
and tv shot on video.
TODAY some HD is shot on tape, but mostly hard drives and
other media are used because they are instant access, and easier to work with.
FILM , on the other hand, has always been "HD".
Even today HD VIDEO HAS A HARD TIME KEEPING UP.
