The human eye can extract more resolution from 2x frames in 3-D than a single 2D frame. Hence CCD cameras with interpolated pixels should theoretically work. My options are

a. 2x HDC-SD9 uncompressed HDMI 4:2:2

b. JVC GY-HM100 uncompressed HDMI 4:2:2

and

a. Linovision HDC-VEC876PF http://linovision.en.alibaba.com/product/529618464-213194157/Wholesale_Full_HD_1080P_2_3_2_0_Megapixel_KODAK_CCD_HD_SDI_camera_HDC_VEC876PF.html

b. Tauri - HD 02150 SDI http://www.kappa.de/en/camfinder/Tauri-HD_02150_SDI_Color%20%20.html?p=1

Turning 8bit video into real 422 http://personal-view.com/talks/discussion/7679/turning-8bit-video-into-real-422 Sat, 03 Aug 2013 16:53:53 +0000 QuinEtiam 7679@/talks/discussions I got a clip that somebody wanted but it was avchd 28mbs.

This agency only accepts Broadcast quality 422.

Got me thinking, so I fired up Cinema4d and went to work.

What if I make a Material texture out of the video and put it on a 1920x1080 rectangle...

A material can have dozens of channels.

I used these channels color, luminance, specular color... each with the video loaded into that channel.

Next, I changed the exposure and HDR gamma on each channel like a bracketed shot -1,0,+1

Then I added a bump channel with the video as texture and applied a tiny amount(1m)

To really add something extra I applied ambient occlusion on the render.

You can add lens flares and make the highlights stand out and apply DOF effects.

The skies the limit.... and your CPU power.

Oh.... my 10 second clip took 3 hours to render.

Anomaly 3D Movie - Shot partially on GH2s http://personal-view.com/talks/discussion/7322/anomaly-3d-movie-shot-partially-on-gh2s Fri, 21 Jun 2013 14:48:38 +0000 David_Cole 7322@/talks/discussions Ripley’s Believe it or Not! in St. Augustine Features World’s First 3D Paranormal Investigation Film

For Immediate Release, June 21th, 2013 – Ripley’s Believe it or Not! in St. Augustine, Florida, will premiere “Ripley’s Anomaly” in its new 3D theater on Friday, June 21st. The ground breaking documentary follows Jack Kassewitz and his team during their three day scientific investigation of Ripley’s historic Castle Warden, the scene of disturbing events since the mysterious and deadly fire of 1944.

Kim Kiff, General Manager of Ripley’s Believe it or Not! St. Augustine, said, “We invited the Anomaly team to investigate the voices and disembodied shadows that visitors to Castle Warden have reported for decades. I was stunned by what they captured on camera. Watching the film in 3D and then touring the building is like watching Jaws and going for a night swim.”

The first-of-its-kind film employs 3D night vision cameras built specifically for the Castle Warden investigation, ultra-sensitive research microphones, and a host of sensors. “We had heard that Castle Warden was haunted,” said the film’s producer Michael Watchulonis. “By the third night in the building, even the skeptics on our crew didn’t want to go into the Vortex Room alone. When you see the attack on our Native American investigator and hear the voices we recorded, you won’t either.”

Research scientist and accomplished journalist Jack Kasswitiz lead the investigation in Castle Warden and the building’s five reported hotspots of paranormal activity. The team focused on the suspicious “Mr. X”, a man who is theorized to have set the fire that killed two women. Kassewitz also tested other investigators’ claims of extreme paranormal activity. “There is no doubt that Castle Warden is the most active site we’ve ever investigated,” said Kassewitz. “Even with thirty years of research experience, I simply cannot explain what we documented in Castle Warden.”

Guests can purchase tickets to the 3D film beginning Friday, June 21st. Shows begin nightly at 7:00 PM and run every 30 minutes until 10:00 PM. Tickets can be purchased from any Ripley’s or Red Train Tour ticket outlet.

Camera Uses Laser Beams to Take 3-D Images 1 Kilometer Away http://personal-view.com/talks/discussion/6647/camera-uses-laser-beams-to-take-3-d-images-1-kilometer-away Tue, 09 Apr 2013 14:37:19 +0000 driftwood 6647@/talks/discussions A team in Edinburgh have developed a camera able to create 3D images up to one kilometre away.

While a standard camera takes flat, 2-D pictures physicists from Heriot-Watt University obtain 3-D information, such as the distance to a far-away object, by bouncing a laser beam off the object and measuring how long it takes the light to travel back to a detector. The technique is called time-of-flight (ToF), and is already used in automative vehicle vision navigation systems and other applications.

The new system works by sweeping a low-power infrared laser beam rapidly over an object. It then records, pixel-by-pixel, the round-trip flight time of the photons in the beam as they bounce off the object and arrive back at the source. The system can resolve depth on the millimetre scale over long distances using a detector that can ‘count’ individual photons. Lots of applications are planned for the technology.

Pictured below: 3-D images of two of the Optics Express authors, taken in daylight from 910m away. Each standard photograph shows a close-up view of what the scanner sees. The middle left panels show 3-D images with slightly more depth detail that the right-hand panels; this is because the detector spent more time collecting the returning photons for the images on the left than on the right.

From their site:

"It's not a conventional camera, but it's like a camera - particularly when it comes to learning curve and ease of use. If you can use a point-and-shoot Nikon, you'll find the Lynx even easier to use. Instead of outputting 2D images, it produces 3D models of whatever you point it at. It's faster and cheaper than existing solutions today. "

" The Object Modeling feature lets you capture detailed models of real objects. The models are accurate to below a centimeter, full-color, and to scale. Export as .obj, .stl, or .ply."

Panasonic Corp developed a 2.1-Mpixel CMOS image sensor for camera systems capable of taking 3D movie with a single lens and announced it at ISSCC 2013

For taking 3D video, it is necessary to separate light into light entering the left eye and light entering the right eye and to make sure that the two types of lights come to different pixels of the CMOS sensor. To realize this, Panasonic employed a structure that combines a lenticular lens and mirror elements (digital micro lenses: DMLs) made by forming patterns whose size is smaller than light wavelength with a lithography technology.

GoPro Hero3 Black 3D http://personal-view.com/talks/discussion/5786/gopro-hero3-black-3d Tue, 15 Jan 2013 11:32:36 +0000 BlueBomberTurbo 5786@/talks/discussions Did some field testing of my GoPro Hero3 Black 3D setup this weekend at drifting. Here's my setup:

3D Rig: image

Shoulder Rig:

image

Test video 1:

1080p60, Narrow FOV, Protune, CamRAW WB

Neat Video, Magic Bullet Looks, a little Shadow/Highlight to recover the clouds

Here's a frame without 3D for reference: image

Gotta say, I LOVE the dynamic range on these cameras! Unless you're shooting something really dark, all but the brightest highlights (ie. the sun) can almost always be recovered in post. There doesn't seem to be much of an issue recovering shadows under most conditions, either. Of course, you'll need to use noise reduction on more serious shadow lifting. I find Neat Video invaluable for heavy processing, as it will remove blocking on smooth areas once you start pushing the limits.


Rig Setup:

Pretty simple, actually. For the 3D part, I got a pair of macro sliders, tore off the rubber surface grip for the bottom piece, removed one of the mounts for use as the top piece, used a 1/4-20 hex standoff to link them together, and slid the GoPros inside. The tension holds them in place perfectly, and the gap from no grip lets me perfectly align the cameras in parallel. The only downfall of this one is that things 5ft or closer tend to hurt the 3D effect, since the lenses are spaced around 3" or so apart. If you're focusing on a subject further back, close objects will look quite a bit off. Same with close subjects, things behind him will be off. After about 5ft, though, everything is fine. I'll be making a more sophisticated and lightweight setup soon, which will allow me to invert one of the cameras to get the lenses much closer.

For the shoulder rig, it's just a Cavision shoulder pad with some 15,000mah USB batteries gaffer taped to a flat section of a flash bracket, screwed into one of the holes in the back. I have a Swivi monitor up front with the 3D rig mounted onto it. It's really lightweight, but I definitely need something more in back to balance it better.

As far as battery life, I left the GoPros running for 6hrs straight. I was able to monitor the battery life through the Swivi's meter, and after that time period, even with the Swivi on, I only used about half the battery. So I should hopefully be able to get around 12 hrs max from that setup.


Here's my Red/Blue workflow:

As far as syncing the left and right, I've found that they're usually about 2 frames off. I try to find and event that is easy to spot on both cameras (subject just passing in front/behind something, light turning on, etc.) to do an easy sync. If that doesn't work, Pluraleyes has no problem matching them up.

Once that's done, I color correct and grade, then apply the 3D Glasses effect in AE. Using the Difference mode, I can align the frames and set keyframes, so the focus can follow the subject no matter where he moves. Then set Keframe Interpolation to smooth the transitions. It's tedious, but the effect is worth it.

Finally, I'll set to Balanced Colored Red Blue and adjust the Red/Blue balance to reduce/eliminate ghosting, scale up to get rid of the edges (aligning will throw them off), and export.


And for Side by Side:

A lot of it is the same, though I seem to have issues with the 3D Glasses effect in Stereo Pair leaving lots of empty space around each frame, and you can't scale each side up individually to fill it. To get around that, I set everything up in the 3D Glasses effect, then export the left and right sides individually. This aligns them properly from the start, so I can get around the empty space issue. Then I do correction and grading, and put them into a double-wide frame next to each other (3840x1080) to get the side by side 3D. YouTube doesn't seem to have a problem with this, though I'm not sure if it would be compatible with any place else.

In the end, it's not really much more work, just more time waiting for it to encode, and with the double wide setup, you get true 1080p 3D.


A note about Premiere/After Effects and 5DtoRGB:

Both Adobe programs will crush the highlights and shadows a bit, at least in Protune. Running the video through 5DtoRGB first will prevent this from happening. It'll also create a much higher quality file than converting through Cineform Studio, since it interpolates color, reducing blocking artifacts. Plus, you can reverse the Cinestyle curve while converting if you want. 5DtoRGB also makes the reds look redder, instead of the slight orange cast they seem to have.

Netflix goes 3D http://personal-view.com/talks/discussion/5725/netflix-goes-3d Wed, 09 Jan 2013 10:05:56 +0000 David_Cole 5725@/talks/discussions

Netflix (NFLX) on Tuesday announced new enhanced streaming options for users on select ISPs. Following a series of rumors that suggested as much, Netflix has confirmed the availability of “Super HD” streaming — which is simply Netflix’s branding for 1080p content — and 3D video streaming. Both services are available immediately with a huge caveat: only Netflix subscribers with Cablevision or Google Fiber Internet service have access to the new content. For those lucky subscribers, Super HD and 3D content is accessible using a number of devices including the Wii U, compatible Roku players, the Apple TV, Windows 8 PCs and select smart TVs and Blu-ray players.

After Effects CS6: 3D Glasses Effect Convergence Problem http://personal-view.com/talks/discussion/5557/after-effects-cs6-3d-glasses-effect-convergence-problem Sat, 22 Dec 2012 15:17:39 +0000 BlueBomberTurbo 5557@/talks/discussions I'm having a problem in AE CS6 when setting "Scene Convergence" in the 3D Glasses effect. If I move it from 0, it'll start leaving blank space to the left and right sides of each clip ( [empty][Left][empty][empty][Right][empty] ). It's visible in all view settings, but most apparent in Stereo Pair (Left/Right), which is needed for the final output. I read that you can scale the two layers individually to get rid of the problem, but all that does is scale both at the same time, in essence just resizing the issue. Any ideas, or tutorials around, that can solve this? Can't find much info about the 3D Glasses effect on the web at all...

Some are cheap TN bases, some are MVA, some very good IPS. With sizes from 23" to 27". And some are actually more like TV, with full tuner and build in player capabilities, common to any modern LG TV set.

Good IPS based 27", like DM2752D, is all you need for everyday amateur work with 3D footage.

Converting 2D to 3D http://personal-view.com/talks/discussion/3178/converting-2d-to-3d Thu, 10 May 2012 19:22:14 +0000 Vitaliy_Kiselev 3178@/talks/discussions Stereo conversion, or dimensionalization as it is sometimes called, is the process of making stereo images from non-stereo traditional 2D images. We originally published an Art of Stereo conversion two years ago, and this is a new updated version of that story covering The Avengers, Titanic, John Carter, Star Wars: Episode I, plus the newest techniques and approaches.

Many people argue that if you want a film in stereo you should shoot it in stereo. Yet many filmmakers do not want the physical size of an on set stereo rig, or they prefer to shoot film (ruling out stereo in camera, effectively) or want to use anamorphic lenses which are extremely difficult for stereo native capture. Even on a stereo film, lenses and situations often times render a single camera the only viable solution. Thus, even on films shot in stereo there may well be a need to convert some footage and that high quality conversion is an important tool in the box of any effects house.

I have a very technical question directed toward those of you who use your GH2 to shoot video for CG and Match-Moved VFX.

When I need to camera track and/or camera project in Nuke or Maya, it is best to put it in the 35mm equivalent focal length of the lens. This is pretty simple with the GH2 since the focal length is just twice the focal length of the lens. EXCEPT, what happens when you shoot in Ex-Tele-Convert mode?

On the one hand the amount of lens distortion seems like it would be the same because the camera's just cutting into the image exposed on the sensor. On the other, It just doesn't seem right that that I should be putting in say, 180mm when the recorded image does not match a 180mm image.

Anybody have some insight into this?

Thanks for any help.

The quality of the motion coding in the latest series of patches for the GH2 (especially Driftwood's GOP3 132M AQ2) is fantastic for 3D - where motion coding fidelity is critically important. I'm pretty sure the GH2 is going to make a hell-of-a 3D camera.
