PMW-400 این دوربین برای تولیدات تلویزیونی در استودیو بطور زنده یا
ضبط
تلویزیونی بسیار مناسب است. در واقع این دوربین یک بروز رسانی
لازم برای هماهنگی با سرعت پیشرفت تکنولوژی ویدیویی است. این
دوربین از خانواده
XDCAM-HD422 با برخورداری از خروجی ENG براحتی برای پخش رنده و همزمان ضبط
تصویر با کیفیت و سرعت بالا طراحی شده است. این دوربین قادر است از 25 - 50
Mbps را با حرفه ای ترین کدکها و فرمت مانند MPEG-HD422 و HD420 و یا
MPEG IMX و البته XAVC برای HD2 ضبط و ارسال کند. برخورداری از 3 سنسور و
Full HD و برطرف کننده دینامک نویز 3DNR تنها مزیت این دوربین محسوب نمی
شوند. برای اطلاعات بیشتر اینجا را کلیک کنید. قیمت این دوربین حدود 17000

Sony’s new PMW-400 shoulder-mount camcorder is the latest addition to
its widely used XDCAM HD422 line-up. Ideal for live production or ENG,
the new camcorder uses a 2/3-inch Exmor™ Full HD 3CMOS sensor to capture
beautiful images with high sensitivity1 and low noise.

“We designed the PMW-400 to acquire high quality, clean images
especially in low-light environments,” said Cyndi Lee, XDCAM marketing
manager, Sony Electronics. “It’s ergonomically-balanced, easy to operate
and includes features that make it fit seamlessly into various types of
productions and workflows. This new camcorder opens the door to a range
of new creative possibilities and flexible shooting.”
Higher Picture Quality with HD422 Codec
Capable of MPEG HD422 50Mbps recording, the PMW-400 is unique among
the field of 2/3-type camcorders with its noise reduction capabilities
and diverse selection of formats. Its 3 Dimensional Noise Reducer (3DNR)
technology accurately detects and processes images to reduce noise,
achieving a Signal-to-Noise (S/N) ratio of 60dB — outstanding among
2/3-type camcorders.
The camcorder supports MPEG2 HD422@50Mbps, HD420@35Mbps/25Mbps, MPEG
IMX@50Mbps, and DVCAM. The PMW-400 camcorder will also offer future XAVC
support for HD.2
Improved Viewfinder
The camcorder’s supplied viewfinder features improved panel
resolution of quarter HD 960(H) x 540(V) compared to previous models
with resolutions of VGA 640(H) x 480(V). The new viewfinder
significantly improves contrast and viewing angles.
Flash Band Compensation via Internal Processing
The PMW-400 camcorder incorporates a valuable new feature – an internal Flash Band Reducer3that
employs a special algorithm to detect and process flash banding inside
the camcorder before recording begins. This provides greater flexibility
in reducing flash banding across different shooting environments.
Operational Flexibility
The PMW-400 camcorder includes two SDI connections that enable, for
example, the director and camera operator to simultaneously check
content on two different monitors.
An optional CBK-CE01 50-pin interface lets the PMW-400 connect to two
camera adapters for multi-camera operation. By connecting to the
CA-FB70 optical fiber and CA-TX70 digital triax camera adapters, the
PMW-400 can be used as a studio camera in live productions and also
transmit signals over long distances while maintaining high picture
quality.
R&D Prototype: Wireless Adapter for 3G/4G/LTE and Wi-Fi Connections
For easy transmission over a network and efficient on-site Wi-Fi
operation, a wireless adapter is under development. The adapter will be
directly connectable to the PMW-400 to enable proxy files that can be
transmitted via 3G/4G/LTE/Wi-Fi to accelerate the ENG workflow. Using
Wi-Fi transmission, the adapter is compatible with mobile applications
installed on devices such as tablet PCs and smartphones.
Future enhancements planned for the PMW-400 include file browsing
management, proxy file preview, stream viewing of camera signals, proxy
and high-resolution file transfer, metadata input and remote camera
control.
