Don, is the above link the right one? I cannot find any 3D 4K solution there.
Yes, it is correct link to the web page. Scroll down to the A9 chip specifications. Here you will see a link to a pdf file. Open that up and page through it until you come to a block diagram of the 4K system board. it is shown with just one sensor and lens assembly plugged in but if you understand how to read it, it shows circuitry for sensor #1
and for sensor #2
. The CEO when asked about the A9 system said it "may include options for 3D stereo if needed by the customer ( aka GoPro) but it would need to limit the frame rate in 3D due to processing speed limitations.". Point being, this technology is a hint of future capability. I would not be surprised if Cue isn't planning to use Ambarella parts to make their version. No company makes every component for a finished product these days, not Apple, not Ford, not Maytag and not even Samsung.
I agree if you desperately need the footage (especially 2D).
On the other hand, I would rather see one excellent 3D video/movie (sharpness, picture quality, stereoscopic alignment, story, ...) than ten average videos. I would rather see no 3D videos at all than bad ones. In my experience, only high-quality stereoscopic videos can improve public opinion about 3D. Shows with lower resolution, bad stereoscopic alignment/depth or badly synched footage do not do any good for 3D (you can find plenty of them on YouTube). I have also seen some 3D videos which were otherwise excellent (the content, story), but few badly aligned or synched clips spoiled everything. Did I want to see those videos again? No way!
I don't beleive you!
I'd bet a ton of money once you saw your perfect/excellent 3D video a few times you would be asking for more. I know a couple hobbyists who work on a video project for years striving for perfection and are never satisfied. Meanwhile I have produced dozens of stories, none perfect by even my standards, but at some point I say it tells the story I want, and I need to move on. Then after 25,000 YT views, not one with a comment that my image wasn't high resolution ( because I maybe recropped the 1080i frame) but people still watch them. It's not easy to get more than a couple hundred views of a hobby video of your vacation, and even less in 3D. But tell a story that entertains and informs, and the audience will watch and enjoy.
I did have one negative comment that my Bellagio fountain video was out of sync by a fraction of a frame. I don't disagree. But, in the overall picture it doesn't matter. To demonstrate that sync problem the complainer had to blow up a frame grab many times and zero in on a water droplet in a frame that was a couple hundred yards wide stage. Had I shot a video of the interesting flapping of the wings of a humming bird, then precise sync does matter and I would have chosen different equipment. What I wanted to achieve in the wide shot is the entire scene without panning.
But that is just my experience, ie. it's the story stupid! The story trumps everything else. The quality only matters if it seriously detracts from the story, like underexposed and dark 3D. Or 3D with severe double images on popouts. I have a few of those too in my experiments in the early days. If the story is interesting, a couple bad scenes makes no difference to me and I would watch it again. The way to get 3D popular is not perfection in one movie. Heck, there was even a debate about the classic 3D game changer, Avatar. It is to offer a 3D medium in a wide variety of content that has adequate quality, read as 'acceptable' to the mass population. Entertain and inform them and 3D will sell! The junk will always be there but the bar for really good will be constantly rising.
Strive for perfection, but be satisfied with excellence. Excellence is a combination of the story that entertains and informs, combined with enough quality that doesn't detract from the story. If the audience is only a bunch of perfectionists, then they will be the judge. If the audience is the world's population, then the numbers is what matters.
