The Sony HXR-NX3D1 NXCAM 3D Compact Camcorder is literally two camcorders in one, facilitating the capture of high-definition stereoscopic 3D video at full 1920 x 1080 resolution. The camera borrows several elements from Sony's NXCAM line, such as the HD native Exmor R CMOS sensor (1/4", with ClearVid pixel array), the 12x Sony "G" lens (10x in 3D mode), and solid-state recording of AVCHD in many formats. (For the HXR-NX3D1, the imaging elements are, of course, doubled.) But as a single-body handheld 3D camcorder, the professional NX3D1 brings several innovations to the table for this emerging class of camcorders.
First and foremost is a 3.5" lenticular LCD display, which allows you to monitor the stereo effect while you're shooting вЂ“ without the need for any glasses. The screen offers several other options, as well: You can view just the left image, just the right image, or a composite mix of both, "flattened" so you can eyeball the disparity between the left and right video channels.
That disparity (convergence) is adjustable. Though the interaxial distance HXR-NX3D1 is fixed at 31mm, you can turn a dial to shift the active image window (i.e. panning across the group of pixels on the CMOS sensors that are actually being read out to the internal storage or SD card/Memory Stick), to dampen or increase the stereo effect of what you're recording.
In 3D mode, the files that the camera records are MVC, short for "multi-view coding." For simpler stereoscopic workflows, MVC files include both the left and the right channel clips as a single file. Sony Vegas Pro editing software supports the import of this type of file, and further support is planned from other editing solutions. For wider compatibility with NLEs, the included Content Management Utility software allows you to de-mix these two channels to independent left and right channels, converting MVC files to two 2D AVC files.
For any handheld video, image stabilization is crucial. For handheld stereo 3D, it's even more so вЂ“ preventing viewer headaches is Job One. Sony's Optical Steady Shot corrects camera shake in three parameters: up/down, left/right, and rotational.
3.5" LCD Shows 2D or Glasses-Free 3D
The HXR-NX3D1U's glasses-free 3D LCD lets you preview high-quality 3D images while shooting. Switching between 2D and 3D display is also possible. In addition, a separate display mode for left or right images, and an L/R composite mix of left and right images are available for easier confirmation of disparity
Frame-Packing or Side-by-Side 3D Output via HDMI
Output from the HXR-NX3D1U's HDMI jack to a 3D TV is selectable between Frame Packing with Full HD output of alternate left and right images, and Side-by-Side with output of horizontally compressed left and right images packed into a single frame. Select the Frame Packing mode for a 3D TV and the Side by Side mode for a professional 3D monitor. Connection is also possible via an HDMI-to-HD-SDI converter to enable compatibility with a wide range of 3D monitors (converter sold separately)
Compatible with a wide range of formats, the HXR-NX3D1U enables 1920 x 1080 (60i/50i/24p) 3D recording and 1920 x 1080 (60p/60i/50p/50i/25p/24p) 2D recording
Internal Memory and Multi Card Slot
The HXR-NX3D1U has 96 GB of internal memory, enabling extended recording in 3D mode for approximately 7.5 hours. And there's a multi-card card slot that lets you record video images on Memory Stick media and SD/SDHC/SDXC Cards. You can also use these convenient recordable media to copy data from the internal memory (media sold separately)
Easy Editing & NLE Compatibility
Easy workflow is an important consideration when creating 3D footage. The HXR-NX3D1U uses Multi-View Coding (MVC) to record left and right channel clips as a single file. Sony's Vegas Pro 10.0d software offers native import support for MVC video files, so footage can be directly handled as 3D clips to enable import of left and right channel clips together. By eliminating the need for time-consuming pairing, this provides an extremely simple workflow. And Vegas Pro 10.0d software provides the ability to adjust, edit, preview, and output stereoscopic Blu-ray 3D and other 3D media with side-by-side, top/bottom, or line-alternate encoding. Support is scheduled to enable conversion of MVC footage recorded with the HXR-NX3D1U to Cineform codec using the popular Cineform Neo3D/NeoHD as a codec plug-in for 3D editing
Converting MVC to Left and Right Channels
The supplied Content Management Utility 2.1 software also enables conversion of MVC video files to 2D AVC files with independent left and right channels. With these capabilities the HXR-NX3D1U is ready for a wide range of workflows
Double Sony G Lens & Double Exmor R Sensors
Inside the HXR-NX3D1U's compact body are two separate cameras, each featuring a high-quality Sony G lens and a high-sensitivity, back-illuminated Exmor R CMOS sensor. High-quality, 1920 x 1080 Full HD left and right images enable the recording of incredibly realistic 3D movies
Optical Steady Shot in 3D
One of the most important considerations during 3D shooting is obtaining stable images to prevent audience discomfort during viewing. The HXR-NX3D1U features Optical Steady Shot image stabilization with Active Mode, with 3-way camera shake stabilizing technology that smoothes out up/down, left/right, and rolling motion when shooting in 3D. Capturing stable 3D images with minimal shake is possible even via handheld shooting
10x Optical Zoom in 3D
When shooting in 3D, the HXR-NX3D1U lets you zoom 34.4-344mm (35mm equivalent). Frame composition while zooming is also possible, just like in 2D shooting
3D Shooting with Two Parallel Cameras
The HXR-NX3D1U features two parallel lenses mounted approximately 1.25" apart (center to center). Disparity adjustment can be performed to change the read-out areas of the left and right CMOS sensors so that they are closer together or further apart. This lets you control perceived 3D depth and the proximity of regions of interest to a virtual screen. Disparity adjustment is also possible during shooting using the manual dial. Moving a region of interest closer to the virtual screen enables shooting of comfortable 3D images with the desired feeling of depth. When capturing 3D images, the minimum shooting distance is approximately 31.5" (at wide-angle setting)
XLR Adapter with Phantom Power and Shotgun Mic
The detachable handle has an ergonomic design that is comfortable and compact. Two balanced XLR audio inputs are built in with phantom power and attenuation options that professional shooters require for clean sound quality. Default audio settings for XLR recording are highlighted in green for easy reference in the field, in order to reduce operator error under difficult lighting conditions. The ECM-XM1 shotgun microphone mounted on top of the handle provides audio recording performance similar to that of larger shoulder-mounted ENG style cameras
Direct Copy to External HDD
Important shots can be backed up by copying footage directly from the HXR-NX3D1U to an external hard disk drive (sold separately) вЂ“ without the need for a computer. Via Direct Copy, the HXR-NX3D1U can also access videos stored on the external hard drive for playback on a 3D HDTV, allowing you to utilize the camcorder's handy 3D playback features.
