How does 3d blu ray work

The 3D effect makes it more vivid to experience the movie while the Blu-ray standard delivers superb movie image and audio quality. However, currently, not all people have 3D TV at home.

Check the below guide and you will get some effective solutions to help you watch 3D Blu-ray movies on regular TV. Blu-ray 3D encoding provides a standard image, plus a transfer function that uses pixel information from the left eye track to construct the right eye track with the appropriate shift in parallax. So, the 3D disc already has a standard 2D Blu-ray as part of the package. A standard Blu-ray player will simply recognize this and play it.

This capability is part of the official Blu-ray specification. However, there might be complications if you have a player that is 3D capable but the TV is not. In other words, the player is just smart enough to create a problem, while a dumb Blu-ray player will just go ahead and do what it is supposed to do instead of nagging the user.

And actually, many 3D Blu-ray discs provide an initial menu that lets you choose between 2D and 3D. But the disc will provide better compression for the 2D disc separately. What can you do if your 3D Blu-ray disc has no 2D mode selection? Check the below solutions to get problems solved.

To do this means you choose to convert 3D Blu-ray movies to videos that could be played back by regular TV. Most active shutter glasses run on batteries; select models are rechargeable.

Most new 3DTVs require active liquid crystal shutter glasses, which work by very quickly blocking the left and then the right eye in sequence. Note that most glasses are proprietary to a particular brand of TV — please consult your user manuals prior to purchase.

Note that there are select 3D-enabled computers that may be available with "auto-stereoscopic" displays — these are displays that allow the user to view 3D without the use of 3D glasses. These displays may not be able to offer full p quality. Some people who seem to have normal every-day depth perception may have trouble viewing filmed content in 3D.

If you have had trouble seeing 3D images in theaters, you may not be able to see 3D at home. Please see your 3DTV manufacturer's instructions for additional guidance.

To viewers not wearing 3D glasses, the 3D image on the screen will appear distorted. There is currently no technology that allows a single 3DTV to display both 2D and 3D content simultaneously without glasses. Note that most viewers who wear prescription lenses should be able to experience full 3D effects. Most 3D glasses are designed to be large enough to fit comfortably over an existing pair of glasses.

It will depend on the movie you have. The main difference between HDMI 1. In many cases you are not able to do so. There is a selection of "3D-ready" TVs that have been on the market for some time which can be 3D-enabled with the additional purchase of a 3D adapter, infrared emitter, and 3D glasses. Please check with your TV manufacturer for further details. When it comes to movies, there aren't many things that are more divisive than the use of 3D Except for the Star Wars prequels and sequels.

Those who love it love it. Those who hate it hate it. There's plenty of misinformation and assumptions to be found. But now, over 15 years after the current iteration of 3D made its comeback, how are things faring, how can you use it, and what is it all about? Here are six basic facts about 3D in With the recent VR virtual reality trend came some confusion. Most of today's VR devices require a smartphone to be put inside them, with half of the screen showing an image for your left eye and the other half for your right eye.

However, what is on those screens can differ. There are some apps, games, and consumer cameras that enable recording in both or and 3D at the same time, but this is the exception. VR devices can be used for traditional 3D content, but we'll get to that later. A video regarding this subject is found below.

One common summarization of 3D in the public consciousness is that it is defined as things coming at you or things leaping off the screen.

This can be true, but it's a gross oversimplification. It is what you see every day, as long as you have two healthy, functioning eyes. Sometimes things are close up, but more often than not, they're far away, and stereo vision is always subconsciously used to enhance clarity and our perception of shape and distance.

As such, being both mundane and beautiful at the same time, it can't be arbitrarily asserted that 3D is only suited to certain genres like animated or action films. Actually, 3D's intricacies can be even better appreciated in slower sequences.

One myth that has been perpetuated and still has a foothold among some is that 3D is only worth watching if it's filmed in that way from the beginning, with a twin-lens camera. However, it's worth noting that no 3D movie conversion has ever been done completely automated but requires manual input by artists. I know because I dabble in this myself. One thing that may have contributed to conversion's bad rep was that in the early era of digital 3D when 3D movies were starting to get mainstream after the success of Avatar, a number of films that were never planned to be released in 3D had a last-minute conversion.

Due to limited time to complete them and lower budgets, they were usually on the subtle side. That doesn't mean they were bad because most weren't. While not nearly as powerful as other conversions, most were accurate and an improvement nonetheless. Today, conversions of this caliber can be achieved very affordably. Nowadays, though, the whole thing is irrelevant. Not only are most 3D films planned on being converted from the very beginning, but the methods and quality have leaped to the extent that the conversions of today, which make up most 3D movies, look just as good or often better than one filmed that way, giving the filmmakers more creative control.

On that note about conversions, it's worth emphasizing that at this point in history, there is no software in existence that is capable of converting media into 3D without any human intervention. If you want to watch 3D, you'll need a 3D movie on Blu-ray, a 3D video game with everything set up properly, a 3D stream from the internet, or 3D content you record yourself with a 3D camera or camcorder.

The automated 2D to 3D feature on your TV or that great cheap 2D to 3D software you see online is, for a fact, too good to be true, with no exceptions. Outside of Blu-ray 3D, stereoscopic video is usually delivered with the left and right eye views squeezed into a single HD video, with side by side being the most common and over and under coming next. One thing to beware of is that some YouTube videos have been converted to so-called 3D by simply duplicating the same video side by side for viewing on a VR device.

Please note, however, that the resulting video will still be flat, as 3D images are slightly different than each other from different perspectives. Anaglyph 3D, the kind where you wear red and blue glasses, has always been a compromise that degraded the picture quality and lessened the potential effect. However, what many don't realize is that the two major quality 3D viewing methods used today have been in place since almost the very beginning.

Shutter glasses, which flicker the left and right views in sync with electronic eyewear, were first used almost a century ago and resurged for home consumer use in the s with the invention of LCDs.

They have been on the market ever since. Polarized glasses, which are simpler and allow a brighter picture, were used back in the 3D craze of the s all the way up to the present. Now, however, they're the most popular format used in movie theaters worldwide. If you're waiting for that elusive glasses-free 3DTV that's always just around the corner, you may be in for a long wait.

While such technology does exist on some cell phones and most notably the Nintendo 3DS, such screens are intended for one viewer at a time. Working with a bigger screen with multiple viewers and viewing angles that wouldn't overwhelm an average consumer is something that a whole other article could be written about. Suffice it to say, don't hold your breath. The technology used today is probably older than you are and provides the best picture quality for the best price.

Maybe sometime down the road, just maybe. The videos below go more in-depth into the various major and obscure technologies used to bring 3D to your eyes over the decades.
