Professional handheld camcorder records 4K using the XAVC format on to XQD solid state memory cards
The PXW-Z100 professional 4K handheld XDCAM camcorder features a 1/2.33-inch Exmor R CMOS sensor with 16 million pixels. The camcorder is ideal for creating stunning 4K content (4096 x 2160) at 50 fps (frames per second) or 60 fps. The camcorder makes it easier for everyone from high-end cinema to entry-level productions to work in the 4K world.
**4K (4096 x 2160) 50fps or 60fps shooting**
The camcorder provides good sensitivity due to the back-illuminated Exmor™ R CMOS sensor. With 8 million effective pixels, the 1/2.33" sensor captures 4K images at 50fps or 60fps. The inbuilt high-performance G Lens offers maximum shooting flexibility, including a wide angle of 29.5mm (equivalent to 35mm) and 20x powerful optical zoom.
**XAVC recording format at 4K 50fps/60fps**
The PXW-Z100 uses Sony’s XAVC recording format first employed in the PMW-F55 CineAlta 4K camera. MPEG-4 AVC/H.264 compression is used for HD (1920 x 1080), QFHD (3840 x 2016) and 4K (4096 x 2160) content. Image sampling is 4:2:2 10-bit, with an intra-frame system that compresses each frame individually at a maximum bit rate of 500Mbps or 600Mbps during 4K 50fps or 60fps recording respectively and 223Mbps during HD 50fps or 60fps recording. The XAVC format is ideal for those looking to implement a high-quality, secure and worry-free workflow.
A free firmware update is planned for the middle of 2014 to support the LongGOP mode for extended 4K recording time and to add support for AVCHD recording.
XQD Memory Card recording
The XQD Memory Card* is a new standard of solid state memory, which was recently defined by several industry leading companies. XQD uses the ultra-fast PCI Express interface and Sony’s unique camera processor to enable stable video recording at 500Mbps or 600Mbps. The PXW-Z100 features two XQD Memory Card slots. Multiple cards can be used in various ways, such as for relay recording. When the first card becomes full, recording continues on the second card without a break.
* XQD cards have a write speed of up to 800Mbps. The use of S Series cards with 180MB/s writing speed is recommended.
**HDMI interface for 4K output and 3G HD-SDI interface for HD output**
The HDMI interface on the PXW-Z100 can output 4K as a 50fps/60fps signal. When the PXW-Z100 is connected to a Sony 4K-compatible BRAVIA TV, the recorded 4K image can be displayed in 4K 50fps/60fps quality. A future firmware upgrade is planned to provide compatibility with the new HDMI 2.0 standard and enable 4K 50fps/60fps output to a wider range of devices. Other features include a 3G HD-SDI interface that supports output to an SDI of up to HD 60fps. It also supports HD output during 4K recording.
**Paint function for more creative freedom**
The PXW-Z100’s paint function enables multiple image parameters to be adjusted including gamma curve, black level, skin detail and colour. The range of settings is similar to those in the PMW-F55. Together with other setting options, parameter settings can be recorded as a camera profile onto a memory card. The recorded camera profile can then be used to set the same parameters in another PXW-Z100 to enable the matching of quality and image tones when using a multi-camera setup.
**Remote control with WiFi**
Focus, zoom, aperture settings and ‘record start/stop’ can be remote controlled using the browser function of a smartphone or tablet.
