The Verge writes an article saying that 4k is wonderful, unlike 3D, saying that 4k is what consumers want. This reporter does not understand the relationship between 4k and 3D at all and seems to think that when 4k comes along, no one will watch 3D.
Most people are unable to distinguish between 720p and 1080p on their large screen home TVs unless they have huge screens. 4k is designed, in part, to present 3D images. Most current 1080p based 3D systems either halve the resolution or halve the frames – with one half to the left eye and another half to the right eye.
A “4k” image is four times the resolution of 1080p (think 4 screens instead of one 1080p screen) and provides the quantity of information to present high quality 3D images.
3D works best when there is as much detail as possible and looks worse when downgraded. A 3D video shot on two 1080p cameras still ends up with the equivalent of 540p for the left eye and 540p for the right eye, or 960 vertical lines, or half the frames devoted to the left and half to the right eye. Either way, today’s system lose a lot of resolution – 4k fixes that too.
I decided this week that I will start shooting 3D video.
I have had an interest in 3D going back to the 1980s, when I visited an exhibit on holography. I read a couple of books on holography but alas, holography was not something I was in a position to pursue.
I recently came across one of those lenticular-based 3D images on the cover of a product and that got me reading about 3D technology once again. After some tests using a single camera to shoot some 3D video of static objects, I found myself hooked! I now plan to get a 2nd camera so I can shoot true stereographic video. (But do not expect to see much here for as much as 1 to 2 months as I have too many other things to deal with before I can get to creating great 3D videos worthy of posting!)
3D, other than in video games, seems to still be stuck in the pre-fad stage of a few experimenters. But this will change, and soon. First, Youtube is providing very good support for 3D – once a properly formatted 3D video is uploaded, Youtube offers to present the video in all of the popular 3D formats – have it your way! Second, Peter Jackson’s movie version of The Hobbit will start to come out in about one year. The Hobbit is being filmed in 3D and I suspect will greatly propel interest in 3D forward.
3D TV will take a long time to arrive, though, because so many people have only just acquired an HDTV and are not in a hurry to rush out and purchase a new 3D HDTV. Over time, as more and more 3D TVs are in use, then 3D content will become more popular. May as well start shooting 3D now as the originals shot today and can be converted to any desired format in the future!
