System Setup and Preferences

Stereo3D CAT requires a video interface device to monitor a live HD-SDI or HDMI signal. The user can also open Quicktime movies. Either discreet (independent left & right) or pre-muxed (Side-by-side).

The Preference menu can be accessed by selecting “Preferences…” in the Stereo3D CAT main menu or by pressing z+ .

User Interface Fade Delay

The Project Window in CAT is designed to fade away after use so the user can take advantage of Full Screen monitoring with the Analysis window. The user can manually set the desired delay time before the` project window fades.

Auto Full Screen (Analysis view)

Stereo3D CAT is designed to run as a Full Screen application. This allows the user to take advantage of 100% of screen real-estate for the Analysis window used for monitoring the stereoscopic input.

By selecting the checkbox Stereo3D CAT will launch in Full Screen mode automatically each time the application is opened.

New Documents Auto-Increment Take Reel

When using the Logging features in Stereo3D CAT, the Auto-Increment setting will automatically increment the take number each time a new Meta Data Log File is saved. This allows the user to easily organize the meta data logged for each shot/setup.

Units

The Stereopsis panel and the Stereo3D Visualizer™ allow the user to pre-visualize scenes, calculate parallax and predict divergence. The input values can be entered in metric or imperial.

Movies Play All Frames

When playing back Quicktime movie files the user can select to force Stereo3D CAT to playback all frames in the movie file, even at the expense of playback frame rate. When this setting is selected, playback frame rate is dependent on the system hardware configuration, Quicktime movie bit rate and media storage configuration.

Enable FPS

The FPS display allows users to discreetly monitor the application’s performance and signal frame rate.

VBL Sync

Vertical Blank Synchronization allow the desired window to render the entire frame before refreshing the display. When VBL sync is off, the upper half of the image will be rendered first, then the bottom half, resulting in a noticable “tearing” effect in the middle of the image. By turning VBL Sync on each frame will be rendered as a single image, removing the effect of a horizontal tear. VBL Sync can be enabled for the Analysis window and Preview window independently.

Video Input

Stereo3D CAT is flexible stereoscopic monitoring and analysis software solution for Mac OS X that supports various video interface devices from Black Magic Design, Matrox and AJA Video Systems.

Stereo3D CAT can also playback discreet (left & right) or muxed Quicktime movies for monitoring and analysis.

Supported Video Interface Devices & Input Type

Once the user has installed the desired video interface device to their system they can begin monitoring live sterescopic input from two cameras, VTR or other playback devices.

When installing a video interface or video input device, the user should update the system driver for their device and install any necessary software from the manufacturer before opening Stereo3D CAT.

The Stereopsis panel controls the Stereo3D Visualizer™ and calculates the values used for the Parallax Inspector™ and Parallax Line Guides. The Stereo3D Visualizer™ is a pre-visualization tool and stereoscopic image calculator. It can be access by pressing the Stereo3D Visualizer™ button in the Stereopsis panel.

Stereoscopic Calculations

The parallax line guide in the Parallax Inspector™ is calculated from values set in the Stereopsis tab. These values include Target Display Resolution, Target Display Size and Viewer Interocular Distance. The user can also enter a custom percentage value if they prefer. However, to calculate the pixel value, the Target Display Resolution must be set.

To have Stereo3D CAT calculate the parallax line guide percentage value of the Parallax Inspector™ go to the Stereopsis tab and check off “Use Calculated Positive Value” in the bottom section. Next, determine the final display screen size. A range between mobile device and IMAX screens are available. In most situations the user will select “Standard Cinema – 30 ft/9.1m”. Next, determine the interocular distance of the average audience member. In most situations this will be 65mm – a value generally agreed upon.

Stereo3D Visualizer™

The Stereo3D Visualizer™ is a stereoscopic pre-visualization tool and stereoscopic calculator. It displays calculated values for positive and negative parallax, geometric similitude, maximum positive parallax percentage and apparent object distance from viewer to screen. The units for the input values can be changed to metric or imperial in the Preference window.

Stereopsis Panel Settings & Values

Camera Interaxial

The user can input a custom camera interaxial distance or choose from a list of fixed-interaxial cameras.

Custom Interaxial

The user can input a custom camera interaxial distance and adjust the slider to see the effect increasing or decreasing the distance has on the resulting stereoscopic image.

Nearest Object Distance, Convergence Distance and Far Object Distance

The user can input the depth budget values for nearest object, convergence distance and far object distance. These values will determine a parallax budget from the interaxial distance, image sensor size and target display size.

Focal Length

The user can select a focal length from a predetermined list or enter a custom focal length. Adjust the slider will actively update the objects in the visualizer to demonstrate the result effect.

Sensor Size

The sensor size is measured horizontally. The user must pick from a predetermined list of sensor sizes. The sensor size, focal length and display size are used to calculate magnification or parallax.

Target Display Resolution

The user must select the target display resolution from a pre-determined list. Options include 640 (SD Square Pixels), 720 (SD Non-Square Pixels), 1280 (720p), 1440 (HDV), 1920 (1080p), 2048 (2K DCP) and 4096 (4K).

Position In Theatre

When a theatre screen size has been selected the user can adjust where the average position in theatre is. This value is used to determine geometric similitude and apparent object distance.

Viewer Interocular Distance/Interpupillary Distance (IPD)

The Viewer Interocular Distance value is used as the threshold for maximum positive and negative parallax within a stereoscopic image. The user can select from 40mm, 50mm, 60mm, 63mm or 65mm. If the calculated positive parallax exceeds the select Viewer Interocular Distance the visualizer will warn of divergence in the stereoscopic image.

Roundness Indicator

The Roundness Indicator button can be toggled on and off to show the geometric similitude of the nearest object – represented by an apple in the visualizer.

Depth/Parallax Budget

If the user has selected Use Calculated Positive Value the value will be displayed in the text box. If the user has un-checked Use Calculated Positive Value, they can enter custom percentage values. These will effect the objects in the visualizer.

Logging

The Logging Panel

Stereo3D CAT offers robust logging features for stereoscopic metadata and project information. This data is saved in XML format and can be referenced for later use or for communication between units and special effects departments.

The XML metadata files log all preferences and settings made by the user in Stereo3D CAT. Including video input type, Geometry settings (convergence &  disparity values in pixels), Stereopsis settings and Parallax Budget values.

User Input Data

When using the logging features the user must save a new file for each setup or take. The user can enter various information including project title, scene number, take number, stereographer, date, extra notes, camera model, frame rate, shutter speed, ISO/ASA, Lens, Aperture, Focus Distance, Filter, Camera Height, Camera Tilt, Camera Roll.

Automatically Logged Metadata

The logged metadata files also include any other adjustments made in the Video, Geometry, Analysis and Stereopsis panel. This data is logged automatically when the project file is saved. This data includes video input signal, image orientation, preview type, convergence adjustment (HIT), vertical disparity, scale (zoom) disparity, keystone disparity, tilt disparity, rotational disparity, horizontal reframe, vertical reframe and scale reframe.

All the logged metadata can be used at a later time or used for reference. Such as during dailies processing, final depth grade and special effects. The data can also be shared between camera units in order to maintain consistency.

Save Reference Images (Left & Right)

The user is also able to save reference images to accompany the logging files. To save references images press the Save References Images (Left & Right) button. Follow the Save As… prompt. Define a directory for the images to be saved then press Save. The images are saved in TIFF format.

Finally, the user can select their desired output mode in order to view their content on 3D displays, YouTube, BluRay or Anaglyph.

Stereo3D Toolbox LE 3.0 is available through Noise Industries’ FxFactory. The plug-in is supported by Final Cut Pro 6, 7, X, Final Cut Express, Motion 4-5 and After Effects CS3-5.5.

What’s New in LE 3.0

Stereo3D Toolbox LE 3.0 is a major upgrade, introducing features such as automated nesting and more stereo 3D Output Modes:

- Side-by-Side

- Above/Below

- Line-by-Line Interlaced

- Checkerboard

- Anaglyph Outline

- 50/50 Superimpose

- Difference

- Anaglyph Colour

- Anaglyph B&W

- Stereoscopic (Hasbro® my3D for iPhone 3Gs & 4)

- 2D Bypass Corrections

Left & Right Eye Nests
Two new plug-ins included in Stereo3D Toolbox LE 3.0 are the automated nesting plug-ins. These new plug-ins allow the user to efficiently create Side-by-Side files that can then be nested before editing. This replaces the convention Image Well workflow used in the previous version.

When working in FCP X simply select the stereopair, right-click and select “Synchronize Clips” then open the new synchronized clip and apply the Left Eye Nest and Right Eye Nest.

S3D Input Type

Discreet Left and Right Video Files (Two simultaneous streams)

Image Wells

The Image Well method allows the user to mux a stereo pair within the Stereo3D Toolbox LE plug-in.

To use the image well method, place either the left or right clip on the timeline then apply the Stereo3D Toolbox LE plug-in. In the S3D menu select the corresponding option – if the clip is the left, select “Clip = Left & Image Well = Right” and vise versa if the filter is being applied to the right clip. Then click and drag the corresponding clip into the image well directly below the S3D menu.

The sequence that the stereo-pair clip sits in can then be nested into a new sequence to begin editing.

Pre-Muxed Video Files

Side-by-Side

Side-by-Side is a very common 3D format. Since the left and right image exist in a single video stream it allows for easy transferability between a hard drive, the NLE and 3D display. In certain circumstances the user may transcode single SIDE-BY-SIDE files before editing to avoid bottlenecking, a common occurrence when attempting to playback two video streams. The user is able to apply Stereo3D Toolbox LE directly to a native SIDE-BY-SIDE file then set the S3D input type to “Side-by-Side” then immediately begin adjusting the convergence and disparity controls.

Interlaced

Similar to native Side-by-Side, a user may decide to transcode single interlaced files. Not to be confused with native interlaced video, when two video fields combine as one whole video frame. Rather the left image is in the odd lines of resolution and the right image is in the even lines.

The user would simply apply the plug-in to the 3D Interlace clip, set the S3D Input type to Interlaced then begin editing and adjusting the convergence and disparity controls. Then finally, selecting the desired Output Mode.

Input Squeezed

The Input Squeezed option allows users to select if a Side-by-Side is squeezed. Conventionally, a Side-by-Side file contains two 1920×1080 video frames that have been squeezed to 50% of their original width, resulting in each image consuming 960×1080 of each frame, equaling 1920×1080.

In certain circumstances a user may decide to work with “Unsqueezed Side-by-Side” video files. This means that both the left and right eye maintains full 1920×1080 resolution but is contained within a single 3840×1080 frame (4K wide, 2:1 aspect ratio). If this is the case, the user is still able to apply the plug-in and use it just as one would with a squeezed Side-by-Side input. The downfall of an unsqueezed Side-by-Side file is the large frame size and increased processor demand. An average editing system will have difficulty transcoding such a file and playing back within Final Cut Pro. However, it is worth experimenting.

Swap Input

Allows users to swap the left and right input incase of an error earlier in the pipeline.

One of the most common errors in stereoscopic 3D editing and mastering/grading is inverted 3D – the left and right eye in the place of one another. For example, a user may have a Side-by-Side video file and the right frame is in the position of the left and the left frame is in the position of the right. The result is inverted 3D and causes objects to be indented and can cause headaches amongst viewers.

3D Output Mode

For previewing purposes and final output the 3D Output Mode gives the user a wide selection of the most popular 3D formats, including; Side-by-Side, Above/Below, Line by Line Interlaced, Checkerboard, Anaglyph Outline, 50/50 Superimpose, Difference, Anaglyph Colour, Anaglyph B&W, Stereoscope (Hasbro® my3D for iPhone 3Gs & 4), 2D Bypass Corrections.

Once the user has finished their edit and made any necessary convergence and disparity adjustments, they’re able to select the Output Mode. The type of display you’ll be viewing your content on will determine your stereo 3D output type. It is important to check what type of 3D input your display accepts.

For sharing your video on YouTube you’ll need to output as Side-by-Side.

3D Output Mode is also important when grading 3D. Modes such as Superimpose 50/50, Anaglyph Outline and Difference are designed for grading.

Side-by-Side

Side-by-Side has become a standard in modern stereoscopic 3D editing that all current professional and consumer 3D displays accept. The left and right video files are squeezed 50% horizontally (each frame equals 960×1080) and placed beside one another in a single 1920×1080 frame. The disadvantage of this format is the 50% loss of horizontal resolution however the simplicity and popularity of this format negates the loss of resolution for most users.

Above/Below

Similar to Side-by-Side, Above/Below squeezes the left and right video files however it does so vertically by 50%. Each clip is now 1920×540 within a single 1920×1080 clip. Most consumer 3D televisions also accept this format.

Line-by-Line Interlaced

Line-by-Line Interlaced is popular previewing format accepted by some 3D displays. The left clip’s resolution is halved then placed in the odd lines of the video stream. Correspondingly then right clip’s resolution is halved then placed in the even lines of the video stream. When combined the video stream totals 1920×1080.

Checker Board

Checkerboard is a method of combining the left and right eye in both the vertical and horizontal resolution. It achieves the highest diagonal resolution out of all the single-stream 3D formats.

When speaking in terms of one line of horizontal resolution, each odd pixel (1, 3, 5, 7, etc…) contains the left images; each even pixel (2, 4, 6, 8, etc…) contains the right. The next horizontal line below the previous will begin with the right images on the odd lines and the left on the even lines. Thus resulting in a checkerboard pattern throughout the frame.

Anaglyph Outline Mode

New to Stereo3D Toolbox LE 3.0, Anaglyph Outline Mode makes correcting image disparity much easier and intuitive. This mode is strictly designed for mastering functionality by creating a very clear visual representation of the difference between the left and right images. Both left image and right images are treated with an edge effect then the left is coloured red and the right is coloured blue. When an edge from both images overlap (no parallax) in turns white. This effect results in a very clear representation parallax and convergence to the user.

50/50 Superimpose Mode

A standard 3D analysis view, 50/50 Superimpose layers the left and right image at 50% opacity. This mode is useful to users who wish to see a simple, unaffected superimposition of the two images. This format is commonly used when calibrating a stereo-rig. This is another mode strictly used for finding disparities between the two images and is not a delivery format.

Difference Mode

Difference Mode is an analysis view. By layering the left and right image, any area with difference will appear as false colours, any areas with no difference turn thus revealing the convergence point or point of no parallax. This mode is also useful for finding geometric disparities between the two images. Difference Mode is not a delivery format.

Anaglyph Colour

Anaglyph is a classic method of viewing stereoscopic images. It is the easiest method to share stereoscopic content without any special display technology or expensive eyewear. Anaglyph can be viewed on any colour display with inexpensive paper and coloured plastic lenses.

The basic principal of Anaglyph is for the parallax in the left image to appear red and parallax from the right image to appear as cyan. The corresponding lenses in the glasses worn by the viewer filter out the opposite eye’s image only allowing the correct eye to be viewed, resulting in two separate images reaching the viewers eyes independently. The viewer’s visual system then processes and combines the two into a stereoscopic image.

Anaglyph can become extremely uncomfortable after extended periods of time due to the heavy colourization of the images and heavy filtering over the eyes.

Anaglyph Black & White

Anaglyph Black & White works within the same principal as Anaglyph Colour however the saturation from the images is completely removed with the exception of areas with parallax.

The advantage of Anaglyph Black & White is the absence of competing chrominance of the images themselves and the colour effect created by the Anaglyph method. For example; an image that contains dominant areas of red or orange chrominance (such as red clothing, skin tone and essentially any red objects in the scene) can compete with the red effect in the left image, resulting in an image that can be difficult for a viewer to fuse resulting in a lose of the stereoscopic effect. This same result can occur with images containing dominant areas of cyan or blue.

Stereoscope

New to Stereo3D Toolbox LE 3.0, Stereoscope output mode allows users to master their project for viewing on the Hasbro® my3D stereoscope for the iPhone 3G, 3Gs and iPhone 4.

2D Bypass Corrections

2D Bypass Corrections output mode only displays the left image and the clip becomes unaffected by any disparity of convergence adjustments the user has made. This is useful when a project has been completed and the user has created a Side-by-Side version, an anaglyph version and wishes to have a 2D version as well. Instead of selecting each clip and removing the plug-in, the user is able to select 2D Bypass Corrections on a single clip and the entire sequence will only display the left image without removing any convergence or disparity adjustments.

Use Global Output Mode

Use Global Output Mode is a setting that allows fast switching between S3D Output Modes and its use is highly recommend. In order to gain full advantage of this feature the user must select the checkbox in every instance of the plug-in, in other words, whenever the plug-in is applied, check the box.

If a user decides to switch from Side-by-Side output to Anaglyph Colour output simply select Anaglyph Colour and check “Set New Global Output Mode”. This will change the output mode of every instance of the plug-in. Global Output Mode is a system-wide setting. If you select this in Final Cut Pro, the settings in Motion and After Effects will also change.

Set New Global Output Mode

Set Global Output Mode works in unison with “Use Global Output Mode”. If the user decides to switch output mode, they can open a single instance of the plug-in in the Viewer window (in FCP), select the new Output Mode then check “Set New Global Output Mode”. This will change the output mode on every instance of the plug-in to the chosen output mode.

Convergence and Disparity Controls

The convergence adjustment slider allows the user to adjust where the parallax budget (depth bracket) sits on the z-axis in relation to the screen plane. The disparity controls allow the user to adjust for geometric disparities between the left and right images. These can be the result of a misaligned camera rig or a bump while shooting. Each slider can be adjusted until the desired position is achieved.

The point of zero parallax or the convergence point is on the screen plane. Objects in a scene that appear behind this point appear to be “inside” the screen, this is called positive parallax and objects that appear in front of this point appear to “come out” (they exist in theatre space) this is called negative parallax.

When shooting, the inter-axial distance will determine the parallax budget (depth bracket) of the scene, or in other words, how “deep” the scene appears to the viewer. Adjusting the convergence point will slide the parallax budget or “depth” either in front or behind the screen plane.

When shooting 3D it is extremely important to be taking measurements of the further object, the convergence point and closest object within a scene and to be making calculations to ensure the proper inter-axial distance is set for the desired convergence point. It can also be described as fitting the depth budget of a scene into the appropriate parallax budget or depth bracket for the desired screen width. If these steps are ignored during shooting the footage may have excessive positive parallax, causing the viewers eyes to diverge or excessive negative parallax, causing extended periods of hyper-convergence, resulting in headaches. There is also the potential for objects in negative parallax to break the stereo-window, also resulting in uncomfortable viewing.

Stereo3D Toolbox LE 3.0 also features Vertical, Rotational and Zoom Disparity controls.

Convergence and Disparity Controls are not keyframeable in Stereo3D Toolbox LE 3.0.

Autoscale

The Autoscale feature automatically scales the frame to remove any black edges introduced as a result of convergence or disparity adjustments.

Swap Output

Swap Output is the same as Swap Input however, as the name describes, the images are swapped during the output. This is useful if the user discovers inverted 3D and would like to quickly swap the two images.

3D Preview Mode

*Not available in FCP X or Motion 5

The 3D Preview Mode is a section window to help analyze the stereoscopic effect. It essentially acts as a secondary display that appears in the Filters tab. The user is then able to preview in the desired output method in the canvas window and analyze with a different output method.

Mix

Standard to most effects, the mix slider adjusts the amount of the effect you see in the final image. Always leave this at 100.

We have been alerted to a potential bug related to the “Field Dominance Mismatch Error” popup alerter window that won’t stop popping up even when “Don’t show this message again” is checkmarked and the alert is closed.

This issue will be addressed in a Stereo3D Toolbox LE v3.0.1 update. Until this update is officially released please download the beta version attached to this article.

“As a result of research conducted through Panasonic Hollywood Laboratory, Panasonic developed a professional 3D system camera and successfully brought high-quality Full HD 3D images to the home for viewing on Panasonic VIERA Full HD 3D televisions. But now, Panasonic has taken it one step further and developed the world’s first consumer 3D camcorder, the HDC-SDT750 — creating a 3D ecosystem available for consumers in the home,” said Chris Rice, Senior Product Manager, Imaging, Panasonic Consumer Electronics Company.  “Incorporating Panasonic’s professional broadcast technology and bringing it to an easy-to-use consumer model, the SDT750 makes high-quality 3D video content a reality in the home.”

As the camera records to a single sensor block, there is no risk that the shots will be out of synch or will have two different exposures. In addition to shooting 3D, the SDT-750 can record full 1080p High Definition (HD) in AVCHD when the 3D conversion lens is removed and includes powerful features like the Leica Dicomar lens and a 12x optical zoom.

3D productions of the past involved a large-scale setup in which two cameras were fitted to a rig in parallel, or vertically intersect across a half-mirror. The 3DA1 Camcorder has been able to achieve this process in one complete unit. The lenses, camera head, and a dual Memory Card recorder are integrated into a single, lightweight body which incorporates stereoscopic adjustment controls making it easier to operate. It provides the flexibility of handheld-style shooting for more challenging shooting environments, making it ideal for sporting events, weddings and documentary 3D projects.

The left-channel and right-channel optical sections, image sensors, signal processing circuits and recording section are precisely synchronized. The AG-3DA1 outputs left-eye and right-eye full-HD image signals as simutaneous HD-SDI video and also records to the SD/SDHC memory cards in the AVCHD format.

Full HD video steams from the twin-lens 3D camcorder can be recorded as files on SDHC/SD Memory Cards, ensuring higher reliability than on optical disc, HDD, tape or other mechanical-based recording systems. This no-moving-part design helps to reduce maintenance costs, and allows for better performance in extreme environments and be more resistant to extreme temperatures, vibrations and shock. Users can expect a fast, highly-productive file-based workflow, with instant, random access to recorded content; easy plug-in to both Mac and PC-based platforms; and longer recording capacity.
