Why Is Stereo 3d Not Ready For Broadcast Tv?
The big hype this year was the Super Bowl 3D commercials with the biggest disappointment coming after most everyone put on those also much-hyped 3D glasses and saw little or no 3D effects.
Everyone needs to know that Dreamworks Monsters vs. Aliens promises to be a big hit on the big screen, and Sam Ramadan believes it will be, because unlike the Super Bowl commercial which was broadcast in anaglyph stereo YB vision (the producers call it Color-Code 3D), the actual film will be shown in theaters in Real 3D and IMAX 3D, which offer a 3D-controlled viewing environment and use stereo polarized 3D glasses that are unisex (independent of feminine or masculine vision).
Too bad the Color-Code Super Bowl 3D glasses were produced and distributed before anyone had a chance to consult with, read and/or learn from Sam Ramadans research and discoveries on how apparently we all have either feminine or masculine stereo vision. It turns out for most of us to see in anaglyph stereo 3D - and instantly perceive depth - we need to be using the right pair of 3D glasses with the matching feminine or masculine stereo vision format.
Sam explains that there are three main reasons why 3D will not work in broadcast TV:
1. Chaotic viewing distance
2. Uncontrolled TV display size
3. The variety of analogue, LCD, LED, and plasma display formats
In the case of this years Super Bowl ads, Sam adds a fourth reason why people were disappointed: the wrong 3D glasses were used.
After reviewing the 1080 pixel wide-screen version of the commercial on his 17-inch MacBook Pro, Sam noted that the commercial would have had to be originally designed to be viewed from a distance range of 45 to 90 cm (about 17 to 35 inches) for the 3D effects to be fully and properly enjoyed.
Sam explains that the normal stereo 3D viewing angle of a human being ranges from about 55 to 60 degrees with a minimum focal distance of about 20-30 cm away from the object (where depth perception is at a maximum).
One thing we all know is that the further away we go from an object the smaller it gets, so there is a strong and direct relationship between perception of size and distance. What most everyone missed noticing is that the further away we go from a real object, the less 3D depth we perceive. This is the main reason why 3D is not ready for broadcast TV, and may never be.
Sam had to sit 60 cm away in order to enjoy the Monsters vs. Aliens 3D commercial on his 17-inch MacBook Pro monitor. But in order for each of you to enjoy the same, how far do you need to sit? Lets assume you have a 42 LCD TV screen at home. To have the same 3D experience, you would need to stand about 50 inches away from the screen (about 1.3 meter), and to watch it on a 60 screen you would need to sit about 75 inches away (about 1.9 meters).
If the TV youre watching is 27, you would need to sit much closer, about 26 inches away (about 65 cm). However, at home, this is not how far we normally sit and watch TV with comfort. At home, many of us tend to sit about 9 to 15 feet (3 to 5 meters) away from the TV, which means, to see the same trailer on a 42 TV, we are likely to lose depth perception because we are beyond the 2.5 meter threshold distance for 90% of the trailer footage, and on a 27 TV screen it is mute beyond 1.5 meters.
To make things worse, most people who watched the Super Bowl did so at a party or in a pubs spacious lounge area where, for most, a 60-inch TV screen would have felt like viewing the Super Bowl on a small hand-held 3 TV screen and would have resulted in little or no depth experience.
As long as one cannot control where people sit or stand and what size screens they are looking at, any 3D broadcast is likely to face failure. Stereo 3D viewing can only be successful in a controlled environment such as 1) Real 3D or IMAX 3D theatres (the latter being the best), 2) computer monitors, and 3) print publications - where viewing distance and visual window size is predictable. In the real world, at the full-angle stereo-view, most of us lose our ability to see depth beyond a distance of 90 feet (about 30 meters).
The above explains the first two reasons for why so many of you put on those 3D glasses and complained that you did not see any 3D effects, and were probably wondering what you were actually supposed to be seeing.
The third reason for problematic viewing is that anaglyphs have never looked good on low-resolution analogue TV sets (this time was no different); they are acceptable on large plasma displays, but look amazingly good in HD on any LCD or LED display. So the type of TV display you were watching also had a lot to do with the level of enjoyment you experienced.
Tip: The best solution to view 3D movies at home is with an HD Polarized LCD or LED home theatre designed with a screen width to viewing distance ratio of about 1:1.5-2.5.
The good news is that Dreamworks publishes the Monsters vs. Aliens trailer online, allowing for controlled PC LCD monitor HD viewing, so some of you still have a chance to see the fantastic 3D effects that you were not able to see during the Super Bowl. The reason we mentioned some of you and not all, is because of Sams fourth and final reason for why many more were not able to see 3D, and how some even experienced headaches: the wrong anaglyph 3D glasses were distributed for the occasion.
How is it that the wrong 3D glasses were used?
If any of you have had a chance to read Sams Do You Have Stereo Feminine Vision or Masculine Vision? article, youll have learned by now that when it comes to anaglyph 3D glasses, the placement of the eye filters is somewhat gender-dependent.
For male audiences it is best to place the high-luminous-sensitive-filter over the right eye and the low-luminous-sensitive-filter on the left, and vice versa for female audiences.
In the case of Red/Cyan Anaglyph 3D glasses, for Masculine vision, you would need the Cyan to be on the left, and the Red on the right, regardless of daylight or dim-light conditions. However it is very tricky with the Yellow/Blue filters Anaglyph 3D glasses as the placement of the filter and gender depends if you are watching in daytime or in dim-light.
People in the US were watching the super bowl in the evening and in bars and pubs daylight conditions do not exist, therefore the blue filter on the right works well for the majority of men, and since the super bowl audience is majority males, then the choice of distributing the MvA 3D glasses with the blue on the left was the better decision. But still an estimated 15-20% of the viewing audience having feminine vision would have been using the wrong pair of glasses to watch the wrong broadcast (the broadcast has to fit the type of glasses being used, whether feminine or masculine.
In other areas of the world where people watched the super bowl via satellite in daylight, most male audiences would have been using the wrong pair of glasses. It would have been a good idea to record the commercials and replay them in day time for individuals with feminine vision to have the better experience.
When masculine-vision individuals try to see 3D using feminine-vision 3D glasses, it takes them time to see 3D, with many requiring more than 30 seconds. Most people give up and just take off the glasses, and those who repeatedly peek through get headaches.
It was best to use Intel InTru 3D to render the commercial in masculine vision and distribute dim-light masculine-vision 3D glasses as they fit the needs of 80-90% of the male population and 65-70% of the female population. (Only less than 10% are what Sam calls eyebidextrous, his new contribution to the Webster English dictionary, meaning people who see 3D quickly with either pair of 3D glasses.)
Furthermore, before the ads played, there should have been instructions informing viewers of the following:
1. Get close to the TV screen at a size perception distance equivalent to looking at an A4-size landscape page held in your hand.
2. Keep the glasses on without taking them off or peeking through.
3. Be patient and let your eyes adjust to the filters.
4. Enjoy the show.
5. Once done, to avoid the headache that only happens with some of those who use the wrong gender glasses, just flip the 3D glasses - thereby making them stereo feminine vision, look through them while counting from 1-10, and voila! no more headaches! It really works.
For those of you who think you have dim-light feminine vision and now wish to rush to your computers and try what Sam suggests
1. Download the Monsters vs. Aliens trailer.
2. Open the hi-res 1080p version it is best to see 3D in the highest resolution possible, as it is the closest to reality.
3. Put on the 3D paper glasses and watch in broad daylight, you dont need to go outside, as enough Suns energy penetrates inside your home.
4. Now you should enjoy 3D viewing like those with YB daylight feminine vision.
If you want to see the trailer in style, make sure you get a durable and stylish pair of 3D glasses from the PHOTO3-D Stereo YB Vision Collection - get the pair that suits you best (currently back ordered).
The problem with the adoption of Anaglyph is that no one really understood fully how it works. This is why Mission3D renamed its advanced version of Anaglyph to Stereo RC format. Mission3D uses a patented spectrum that allows for great viewing for printed matter which is mostly seen under either daylight or daylight conditions. Stereo RC 3D glasses technology from Mission3D is best for printing, while polarized technology is best for the movies.
We hope that next time, organizers will work harder to provide you with a more pleasant and enjoyable experience. For any of you who would like to experience the best-ever 3D produced in print, please feel free to visit www.mission3-dgroup.com or email [email protected]
