What is the difference between hfr 3d and digital 3d

There was no 3D, no HFR but the other tools of cinema such as focus, lighting, perspective, point of view, clarity, motion all played into this experiential saturation.

Finally this seems to be a learned and learnable behavior. Perhaps like motion sickness in the first motorized vehicles, we have to provide a training regime so that audience members can learn how to handle the HFR experience. Did they compare it to 24? Very true that it actually might be the case because of stronger immersion feeling, but, all in all, this is a hearsay based on practically nothing.

The people might have problems with stereo in general. For one thing I want to see what is lost on the wide screen compared to the taller Imax version, and also see what is gained from 48 fps. The real way to make a true comparison is to watch a sample of them side by side, or split screen to really tell which is better.

I have no idea whether increasing the framerate with active glasses would help or hurt me. Projectors need to be upgraded to do triple flash on 48fps and up. They used dual projectors. I believe what causes headaches are differences between the focal point and focus. Differences between parallax and perspective too. Small differences occur when you shoot with two cameras and rig. When have these differences the nerve and the brain work hard to compensate.

It may be that the HFR has amplified these problems. But I think the HFR is an revolution in terms of image and certainly not guilty. Nvidia 3d Vision works very well on higher frequencies and without headache. Bit like anologue music, still love the sound of it best over the much harder although technicaly perfect digital.

And ultimately that is what I think we have here. Please explain? If there becomes a legal precedent in this area then i expect a HardingFPA sort of device will need to be implemented. If so I expect such a device would also have to check for what Pompeu Soares highlighted, and that is directors abusing cross-eye viewing or creating cross-eyed jump cuts.

This impacts on perception-related temporal stereoscopic artefacts like moving objects shifting in Z-depth: the more flashes, the less the artefacts due to the reduced time the left and right brain sides have to argue about where an object resides in depth.

HFR only brings benefits to the image. Most movie theaters in the world do not have a comfortable distance between the screen and the first chairs. Would have to take at least 6 rows to ensure a good 3D with negative parallax. This lack of distance determines the pattern of parallax down. However it would not be economically acceptable. I would like to propose this discussion. But I see rooms with much less than that.

The average is between 6 and 10 meters. I am not talking about flicker perception but stereoscopic continuity, which can make the observer queezy as well. And if with Domestic equipment we can do Hz 60p per eye.

I do not believe professional companies such as Christie have problems in this way. But I know how this works. Even with powerful digital equipment, some directors still dazzle with the glamor of 24p. Have you considered cost? No Sony sales people admitted to it. What is the Xtreme format being promoted by Cinemark theaters? Is it just large screen 4k RealD? We are leading providers of 4D technology in themed attractions globally and now in cinemas, with our 1st installation in Mexico City with Cinemex.

Thanks Mr Blair for the comment I want to make movie theaters with 3D screens whether IMAX or Sony with 4D in the Hall effects to create the viewer be part of the film and have an unforgettable experience. Also at the entrance to the theater there will be figures of artists in holograms by welcoming people to see the premiere of his films I believe to be innovative and would like visitors to the cinema. Pablo, I can assist with the Halogram figures as well.

Please give me a call. Bravo et merci! I know that the newer projectors used for ReelD are capable of 48 fps and some at 60 fps James Cameron is shooting the Avatar sequel at 60 fps. I also wonder — if the IMAX projectors ARE higher frame rate ready — if they could run into some serious problems syncing the two projectors.

Going from 24 to 48 or even 60 progressive frames per second will only yield a mild visual improvement, and that improvement in visual quality is due to the fact that since there are more key frames overall, they will naturally play more smoothly than lower key frame values would. Currently, movies filmed at 24fps You heard correctly. Since RealD uses a single projector with a circular polarized lense, that one projector MUST have a refresh rate of hz or some higher rate that is divisible by So really, for a 24fps 3D IMAX film, each projector only needs to be capable of 72hz, not the higher hz refresh rate of other forms of 3D film like RealD.

Double Flashing is exactly the same as Triple Flashing except that each frame is duplicated instead of triplicated when being projected. So a 48fps film would end up being shown at fps, and a 60fps film would be shown at fps. Imax glasses, because they are linearly-polarized, can actually produce unwanted artifacts. Heey there terrific website!

Does running a blog suych as this require a great deal oof work? I have no knowledge of computer programmng however I hhad been hoping to start my own blog soon.

Anyways, should you have anny recommendations or tips for new blog owners please share. I know this is off topic but I smply had to ask. Appreciate it! Hi guys, nice article. But you got a mistake in there: It is not about a certain spectrums of light, it is about the wave-oriantation.

Circular polarization filters work according to the same principle as linear polarizers. Optical gratings let only pass light waves with matching orientation. So you send out the movie in two different orientated signals. One Vertical and one Horizontal. The glasses on each side only let through wavelength of on of the directions.

If you had issues and 40 years of life to realize you had been wrong, wouldn't you wonder if you were wrong again. I sure do. I am now roughly the same age Dave Sim was in This is a conundrum that I think about reas. You mention that 2K projectors provide twice the resolution of Full HD.

And i am satisfied studying your article. But should statement on some normal things, The site style is perfect, the articles is in point of fact nice : D.

Excellent process, cheers. My wife and I tried watching a digital 3D movie at a local IMAX, and we had to walk out after 15 minutes and exchange our tickets for the RealD version of it…. Half the screen was lighter than the other; we might as well have been using those old red and blue glasses!

Thank you for this input. My eyes cannot deal with those kind of glasses. I basically get not 3d effect because of my severe keratoconus. I will be sticking with real 3d. Thank you for this article! I always wondered what the difference between the two was. The articles have been very informative but are bit dated for me at this time. I am curious if anyone has watched the new Star Wars movie and which way it is best to be seen. For one not so important thing, Star Wars TFA was cropped off at the top and bottom to fit the real 3D screen, you lost a bit, not massively important or earth shattering but after watching it at IMAX in 3D first on premier night and then later on Real 3D, it was noticeable when a sound effects played with no accompanying visuals….

With red green I saw a red and a green image overlayed on each other with or without the glasses. Not all of these features will be available in your area, and many of them will be mixed and matched depending on what features have been added to your local theaters.

You will have to check either with the theater itself or with the ticketing website of your choice to get an idea of what flavors of BOTFA will be shown. Here is a comprehensive list of the various options you are likely to find:. This also gets more complicated with the Trilogy screenings that will be happening on December 15th. The formats may change between the movies themselves. We hope this prepares you for what you can expect, and that you know what to look for when choosing how you will venture into Middle-earth.

It really is a very crazy list of options. Sound off in the comments below with your thoughts on all of these formats, and which ones you like or dislike.
