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 AG-3DA1 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.
The Integrated Structure Revolutionizes Mobility for Nimble Camera Work
The AG-3DA1 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). AG-3DA1 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.
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.
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.
HDMI 3D Output
The AG-3DA1 features an HDMI output terminal that outputs FULL HD 3D video signals for viewing on 3D VIERA and Panasonic 3D plasma displays. This terminal outputs camera-through signals or left-channel/right-channel FULL HD 3D playback signals.
*1: HDMI output and HD SDI output cannot be used simultaneously.
3D Compatible Camera Remote
The AG-3DA1 camera remote terminal allows remote adjustment of the convergence point in addition to the focus, iris, zoom and REC start/stop.
