The Integrated Twin-Lens 3D Camera Recorder Accelerates 3D Video Production


Real-life 3D images are expected to find widespread application in fields ranging from movies and TV broadcasts to industrial and educational uses. In response to the rapidly growing needs for 3D image production, Panasonic now offers a revolutionary solution: AG-3DA1 the integrated twin-lens FULL HD 3D camera recorder. The AG-3DA1 features a camera section with two integrated lens systems that are configured to resemble the human eyes, and a recorder section that records left-channel and right-channel full-HD images using the high-quality PH mode of the file-based AVCHD format. With the same approximate weight and size of a 2D camera recorder, the AG-3DA1 is easy to handle. It&s also quick to operate, as it doesn&t require any adjustment of the left and right lens alignment such as vertical gap, size difference, rotation and luminance difference.

The AG-3DA1 frees the user from the kind of complex, cumbersome procedures of a conventional rig-type 3D camera system. Data files recorded onto a memory card are readily processed using a nonlinear editing system. With its excellent mobility , flexibility and low cost operation, the AG-3DA1 opens the door to 3D image production.

Schematic of the AG-3DA1:

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 simultaneous HD-SDI video and also records to the SD/SDHC memory cards in the AVCHD format.

 

Twin-Lens System


The high-precision HD twin-system allows easy acquisition of natural looking 3D images.


The Integrated Structure Revolutionizes Mobility for Nimble Camera Work

Conventional rig-type 3D camera systems are large and heavy because they mount two existing cameras onto a robust frame. They also require a separate recording system and power supply unit, which makes the cable connection complex and restricts the location and the type of camera work. As a result, the scenes that can be acquired with a rig-type 3D camera system are limited. The compact body of the AG-3DA1 integrated twin-lens FULL HD 3D camera recorder weighs only 2.4 kg (5.3lb). It offers the same portability and mobility as a conventional 2D camera recorder for flexible image acquisition. The AG-3DA1 enhances camera work for all kinds of 3D image production.



The Twin-Lens System Sets You Free From Complex Camera Adjustments for 3D Images

To achieve natural-looking 3D images, you need to pay close attention to the following key points for left- and right-eye images: (1) Vertical deviation, (2) Angle deviation, (3) Difference in brightness and color, (4) Rotation error, (5) Correct adjustment of the convergence, (6) Appropriate image composition. With a conventional rig-type 3D camera system using two separate cameras, these adjustments have to be made precisely for each and every scene. The two integrated optical systems of the AG-3DA1 eliminate the need for manual adjustments of (1) through (4), because they&re performed entirely inside the camera recorder.* The optical systems are assembled with high precision, and the lenses, image sensors and signal processing circuits for the left and right systems are accurately synchronized (see the diagram on the previous page). The AG-3DA1 lets you concentrate only on the convergence adjustment and image composition. *Fine adjustments of the vertical position, focus and iris are also possible.

HD Twin-Lens with No Adjustment for Image Acquisition

The distance between the two lens axes is approximately the same as the distance between the human eyes, to provide easy-to-view, natural-looking 3D images. The HD twin-lens system is set with a distance of about 60 mm (2.3 inches) between the two lenses. The lens axes, viewing angle, rotation, and gradation are pre-adjusted before the components are precisely assembled. This eliminates the need for lens adjustment before shooting. Camera operations such as focusing, zooming and iris adjustment are also synchronized for the left and right lenses.

The new twin HD lenses were designed exclusively for FULL HD 3D image acquisition. They boast low chroma aberration and high resolution, and deliver superb color reproduction, detailed nuances and crisp 3D images even in dark scenes - with minimal flare and ghosting. A built-in 5.6x (approx.) optical zoom function, which extends from 47.1 mm (35 mm equivalent) wide angle to 264 mm (35 mm equivalent) telephoto, covers a wide viewing angle that is well matched to 3D content production.



Convergence Point Adjustment Function

The convergence angle between the two lenses is varied inside the optical unit. This moves the convergence point (the reference plane of the 3D image) in a fore-and-aft direction to control the leaping and depth effects of recorded objects, and acquires natural-looking 3D images. The convergence point can be adjusted easily by using the CONV (convergence) dial* while viewing the L/R-MIX image on the LCD monitor.

*The dial function is switchable between CONV (convergence) adjustment and IRIS (iris) adjustment.

Display Functions Assist 3D Image Acquisition
The LCD monitor and viewfinder of the AG-3DA1 both display a variety of information to assist 3D image shooting and ensure superb 3D effects.

3D Guide:
This displays numerical values for the distance range of the subject to achieve better 3D effects while viewing. Natural-looking 3D images can be captured by using the displayed information as a guide. This function offers two modes: Guide Display 1 mode assumes playback on screens that are 196 cm/ 77 inches or smaller, and Guide Display 2 mode is designed for a screen size of 508 cm/ 200 inches.

Convergence Point:
This displays the numerical value of the convergence point together with the 3D Guide to assist adjustments.

L/R-MIX Monitor Image Selector:
The image display on the LCD monitor and viewfinder can be selected from three modes: Left Lens (no mode indication), Right Lens (R-IMAGE) and Left/Right Mix (MIX). *When the subject is located outside the distance range indicated by the 3D Guide, it may result in a double image or an unnatural image without proper 3D effects.

This design assures easy shooting even at low angles. The excellent mobility of the AG-3DA1 allows flexible camera angles that are not possible with other 3D cameras.

Memory Card Recording


The file-based recording system and digital interface achieve a comfortable 3D image production workflow


File-Based Recording to Two Memory Cards
Using the two Left/Right memory card slots, the AG-3DA1 records left-channel and right-channel full-HD images simultaneously to two SD/SDHC Memory Cards. The solid-state memory card ensures high reliability and withstands operating temperatures of –25°C to 85°C (-13°F to 185°F). This enables use in harsh temperatures and fluctuating humidity. It is also free of dropouts and head clogging. With memory cards, there is no need to search for a blank space to record. Data is automatically recorded in an available space. This eliminates accidental overwriting of existing data. After shooting, recorded clips can be previewed or deleted immediately. After recording, data can be uploaded to editing software without digitizing. SD/SDHC Memory Cards are inexpensive and can be easily purchased in local markets. * Use SDHC/SD Memory Cards of Class 4 or higher. SDXC cards cannot be used.

HD Multi-format Recording
Multi-format HD recording in the AG-3DA1 responds to a host of 3D content production needs and worldwide applications. It supports the following HD video formats. The maximum recording time is approximately 180 minutes in each mode (when two 32 GB SDHC cards are mounted in the Left/Right slots).

AG-3DA1 series Recording Format






* In Native mode, the AG-3DA1 records only active frames.

AVCHD PH Mode for FULL HD 3D Recording
The AG-3DA1 records in AVCHD PH mode, based on MPEG-4 AVC/H.264 High Profile, which is the latest video compression technology. With more than twice the compression efficiency of MPEG-2 (such as in HDV), AVCHD provides both high image quality and a low data rate. PH mode was developed by Panasonic exclusively for AVCCAM professional video production. Boasting 24 Mbps (average: 21 Mbps), which is the maximum bit rate for the AVCHD format, the AG-3DA1 records 1920 x 1080 full-pixel HD images. The multi-slice feature of the PH mode also helps to speed up processing by nonlinear editors that are equipped with multi-core CPUs, by using parallel processing to take full advantage of the CPU power.

Sample comparison: When a flash causes large contrast differences and reduces correlation of consecutive image, HDV shows considerable block noise, while AVCHD in the PH mode minimize break-up.

Comparison of HD Recording Formats

Versatile Solid-State Recording Functions
• Thumbnail View for easy playback or deletion of clips
displayed on the LCD monitor
• Shot mark: Allows convenient OK and NG marking, and can be
added to each clip during or after recording.
• Rec check: You can check the end of the most recently recorded
clip with one-touch ease.

Clip Metadata Function
You can create a metadata upload file (produced with AVCCAM Viewer software) containing information such as clip name, the name of the camera operator, the recording location, and text memos on an SD/SDHC card, and load it as clip metadata. This information will be very useful when it comes to editing the project and quickly finding the right clip to place on the timeline.

Professional-Level Audio Input
The AG-3DA1 is equipped with two audio input channels for digital audio (Dolby Digital) recording. The AG-3DA1 also comes equipped with a built-in stereo microphone and with XLR-type audio input terminals (2 channels, mic/line switchable, 48 V compatible) on the rear panel. You can switch audio channels 1 and 2 separately to either line or front mic input. Large level adjustment dials are easy to operate and offer high visibility.

3D Acquisition System
Connecting the BT-3DL2550 3D LCD Video Monitor via HD SDI Dual-Link lets you view the stereo image so that you may adjust the 3D image to create the effect you want by varying the focus and convergence point.

3D Content Editing System
3D video data recorded by the AG-3DA1 can be edited by a computer-based (Windows/Mac), low-cost nonlinear editing system installed with a 3D editor plug-in (third-party software, sold separately)* that supports existing AVCHD-compatible video editing. The use of files allows easy ingestion to a computer, much in the same way as in ordinary 2D image editing. The addition of the 3D plug-in also lets you adjust the 3D images. This plug-in produces a DVI-D video output so that images can be viewed and checked using the BT-3DL2550. Editing results can be saved in an external storage unit for handover to the subsequent process (MA/Blu-ray 3D™ authoring, etc.). * Panasonic does not guarantee proper operation of third-party software.
