JVC GY-HM850-XT20 Full HD camcorder, Fujinon XT20 lens, Wi-Fi/FTP
JVC's GY-HM850 offers the same performance and same basic features as the GY-HM890 minus the interface to a full studio setup, and minus HD pool feed. On your shoulder, its solid feel gives you the confidence that you are working with a camera you can count on--even in the most difficult shooting conditions. All of the controls you need are at your fingertips right where you'd expect them. Three new CMOS sensors ensure that picture quality is second to none whether you are producing HD, SD or for the web--or all of the above! With JVC's Advanced Communications Technology, your content is delivered instantly to the studio and even to your viewers.
High Performance Full HD 1/3-inch CMOS Sensors
3CMOSAt the heart of the GY-HM850 are three 1/3-inch 2.07 effective-megapixel CMOS sensors, each capable of capturing full HD 1920 x 1080 resolution images. Featuring 12 bit read-out, an excellent sensitivity of F11 (60Hz) / F12 (50Hz) and a remarkable signal-to-noise ratio, the devices provide superior precision and color reproduction with minimal aberration. For improved CMOS sensor performance, flash-band compensation is also supported.
Outstanding sensitivity, LoLux function
The GY-HM850 produces outstanding images under a wide range of lighting conditions. Minimum illumination is less than 1 lux: 0.15lx (typical)*. JVC's exclusive LoLux feature permits shooting in adverse lighting conditions. LoLux can be assigned to a USER button, and set in the menu to offer +30dB or +36dB of gain. A convenient gain switch provides default gain values of -6dB, 0dB, +9dB. These switch positions can be adjusted to various gain amounts from -6dB to +24dB. An ALC mode is also available to boost gain values from +6dB to +24dB. Standard sensitivity of the GY-HM850 is measured at F11@2,000 lux. ADVANCED PROCESSING ENGINE
Revolutionary FALCONBRID Dual Codec Image Processing Engine
FALCONBRID™ is JVC's high-speed processor for advanced video applications. Delivering tremendous processing power on a single chip, the on-board FALCONBRID™ engine processes large amounts of video data at exceptional speeds. Together with this technology, superior image quality has been realized with 2D DNR processing and compensation circuitry for wide dynamic range. The GY-HM850 utilizes dual codec FALCONBRID™ processors that make it possible to record full HD to a memory card, and stream live video to the web simultaneously. The camera is also capable of recording to two memory cards in two resolutions—one in full HD and one in SD, or to a smaller web-friendly file. Depending on connection speed, the smaller files can often be transferred faster than real time for delivery to websites or file-sharing services.
MPEG-2 and AVCHD Recording
The GY-HM850 supports both the popular MPEG-2 Long GOP 35/25/19Mbps format, widely used by television broadcasters, and the highly efficient AVCHD format, which provides compatibility with most affordable editing systems. This means that professionals have unprecedented flexibility to meet production standards through a wide range of workflows. With the revolutionary dual codec, the GY-HM850 also supports simultaneous HD/SD or HD/proxy recording. Also supported is the MPEG-4/AVC H.264 1.2 Mbps SD format.
Ultra and Extreme High Quality Recording Modes
The GY-HM850 is also equipped with the H.264 Extreme High Quality (XHQ) 50Mbps mode for virtually lossless compression—even when recording fast moving objects. MPEG-4 AVC/H.264 offers approximately twice the compression efficiency of MPEG2. Its superior motion prediction ensures a smooth and detailed picture with virtually no block noise in rapid action sequences. The XHQ mode is available when recording 1920 x 1080 at 60p,60i,30p and 24p.
The GY-HM850 further provides the H.264 Ultra High Quality (UHQ) 35Mbps recording mode, again offering superior image quality but with smaller file sizes.
Multiple File Formats for Native Workflows
Record HD or SD footage directly in ready-to-edit QuickTime™ MOV files, the native file format of Apple's Final Cut Pro™. Native file recording ensures your footage is ready to edit the moment it's shot, resulting in a more efficient workflow and no loss of image quality. For direct editing in other major NLE systems such as Avid Media Composer, Adobe Premiere and Grass Valley Edius Pro, it is also possible to record XDCAM EX compatible MP4 files for a likewise seamless native workflow.
Support for MXF Files with Rich Metadata
A highly efficient file-based workflow is essential to any modern news organization. To ensure file interoperability with the widest range of broadcast production tools, JVC has worked with the Advanced Media Workflow Association (AMWA) on its "AS-10: MXF for Production," establishing a common MXF file format for an end-to-end news production workflow. MXF files are embedded with rich descriptive metadata that is added before, during or after shooting. The AS-10 MXF format builds on the SMPTE RDD 9, the MXF interoperability specification of Sony MPEG Long GOP Products (XDCAM HD.)
Dual SDHC/SDXC Card Slots for Maximum Versatility
Dual SDHC/SDXC card slots make the GY-HM850 a truly versatile camcorder, offering such benefits as simultaneous recording and relay recording with reliable and cost-effective media. In relay recording mode, you can shoot continuously and seamlessly over multiple cards. When one card is full, the camcorder switches seamlessly and automatically to the other card. And because cards are hot swappable, there is in effect no limit to the continuous shooting time in any mode, even with lower capacity cards.It is possible to start editing footage from one card while still shooting to the other. With simultaneous recording, you can easily create backup or duplicate files as you shoot without the need for any external equipment—either for a client copy or simply for peace of mind. Additionally, while the Rec trigger is used to pause and unpause recording on one card, the other card can act as a continuous backup that overrides the pause function.
SDHC/SDXC media offers the best combination of price, availability, capacity, reliability and transfer speed. With no moving parts and no pins or other extrusions, SDHC/SDXC cards are both durable and reliable, and compare favorably with tape on a cost-per-minute basis.
