GY-HM850

FALCONBRID™ Image Processing Engine

FALCONBRID™ is JVC's high-speed processor for advanced video applications. Delivering tremendous processing power, 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 dynamic range compensation circuitry.

MPEG-2/AVCHD Recording and Dual Codec

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 progressive format, which provides compatibility with a wide range of affordable NLE systems. This means that professionals have unprecedented flexibility to meet production standards through a wide range of workflows. The dual codec also enables the GY-HM850/HM890 to offer simultaneous HD/SD or HD/Web recording, producing full HD files on one memory card while creating smaller, Web-friendly files on the other. Also supported is the MPEG-4/AVC H.264 8Mbps SD format.

Virtually Lossless H.264 50Mbps Recording

The GY-HM850/HM890 is also equipped with the H.264 Extreme-High Quality (XHQ) 50Mbps (MOV) recording mode used in HD SLRs. MPEG-4 AVC/H.264 offers approximately twice the compression efficiency of conventional codecs, and offers superior motion prediction, so even at the same bit rate it provides a smooth and detailed picture with virtually no block noise even when recording rapid action sequences. Added to this, the 50Mbps bit rate is high enough to support full 1920 x 1080 encoding in 60p or 60i, resulting in stunningly detailed HD images.

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 with lossless 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.

High-Resolution 4.3" LCD Monitor

The high-resolution 1.15M-pixel 4.3" LCD monitor displays a wide variety of monitoring and setup indications.

0.45" LCOS Viewfinder

The GY-HM850 is equipped with a high-resolution (852 x 480 x 3) LCOS (Liquid Crystal On Silicon) 0.45" viewfinder. The 16:9 image is crisper and more detailed than conventional LCD viewfinders, with higher vertical resolution and superior RGB color separation.

Histogram Display and Expanded Focus Functions

The GY-HM850 features Histogram Display and Expanded Focus functions to support more accurate focusing

Focus Assist Function

When Focus Assist is switched on, the image in the viewfinder of LCD monitor switches to monochrome and all objects that are in focus appear with colored edges (selectable from red, green or blue). Keeping important elements in the picture in focus while shooting is greatly simplified.

Intuitive GUI

The GY-HM850 features ProHD's highly intuitive GUI navigation system, providing easily accessible menu items and customizable settings to match individual preferences or demands of the moment.

12 Assignable User Buttons

Pre Rec and Interval Rec Modes

With Pre Rec enabled, the camcorder continuously buffers up to 10 seconds of video, so that when recording is started the cached video is included in the recorded file - keeping you from missing a crucial shot because you didn't hit the record button in time. Interval Rec allows you to record single frames at set intervals to capture time-lapse recordings of street traffic, construction sites, growing plants, etc.

Variable Frame Rate Recording (Over Cranking, Under Cranking)

When recording in the H.264 1080p 50/35Mbps or MPEG-2 720p 35Mbps mode, the camera can be set to record at a frame rate different than the playback rate. This makes it possible to record slow or fast motion when the recording is played back at 24p,
25p or 30p. Under-cranking in the MPEG-2 1080p 35Mbps mode is also possible.

Cutting-Edge Connectivity

The GY-HM850/HM890 meets the needs of professional applications with cutting-edge connectivity. For easy monitoring of footage, you can monitor from the digital 3G SDI and HDMI outputs simultaneously, easily switching between output in HD or SD.

Wired Remote Control Operation

In addition to JVC's proprietary wired remote control system, the GY-HM850/HM890 also supports LANC remote controllers for flexible camera operability in a variety of setups.

Genlock Input and TC Input/Output

Equipped with genlock input and timecode in/out terminals, GY-HM850/HM890 can be easily integrated into multi-camera setups.

4-Channel Audio System

The GY-HM850/HM890 is equipped with two XLR audio inputs that are switchable between microphone (with phantom power support) and line input, plus stereo AUX inputs. The audio from each of these inputs can be assigned to an independent channel, enabling commentary or narration to be added in the field

ProHD Supporting Software

The ProHD Clip Manager for both Mac and Windows makes it easy to manage MP4 clips on the GY-HM850/HM890's memory cards from your computer. Copy, move, delete, preview clips, and edit clip metadata.
The ProHD Log and Transfer Plug-in works with Apple's Final Cut Pro™ to enable MP4 files recorded on the GY-HM850/HM890 to be dropped into the clip bin and automatically converted to QuickTime™

Network Connectivity & Workflow Outline

Direct File Transfer from Shooting Location

JVC offers a distinct advantage of having the network connection engine built-in. So it's only necessary to connect either a Wi-Fi, 4G-LTE/3G modem or USB-RJ45 adapter to the USB host interface. No optional backpack is required.

Camera Control and Metadata Editing via Network

Camera Picture Viewer/Remote Function
LIVE picture can be viewed on a smartphone or tablet (Android, iPhone, iPad). What's more, REC/PAUSE and ZOOM functions can be controlled from the smart devices via Wi-Fi.

Metadata Editing and Upload Function

Planning metadata and clip metadata can be edited at a smartphone or tablet and transferred to the camera via 4G-LTE/3G* or Wi-Fi.

Built-in GPS

A GPS unit is built-in, enabling location information to be recorded as metadata along with the video data.

Advanced Streaming and Cloud Services

While the GY-HM850 can record high quality video/audio onto SDHC/SDXC cards, it is also capable of transferring LIVE streaming video/audio via network. Coupled with the superior mobility of the camera, this wireless capability enables faster delivery of LIVE video in mission-critical ENG applications. Stream backhaul LIVE to the newsroom using either Wi-Fi or 4G-LTE network, whichever is more stable and cost-effective in your area. In addition to conventional UDP/TCP support, the GY-HM850/HM890 also supports RTSP/RTP*1 and Zixi protocols. With built-in Zixi engine, connecting to a 4G-LTE/3G or Wi-Fi network is simply a matter of plugging in a USB network adapter*2. The technology also allows the GY-HM850/HM890 to be used in conjunction with Zixi's cloud delivery service which enables reliable video delivery over the Internet simply by entering a single IP address. Additional applications such as live, direct-to-website broadcasts and delivery to public internet sites are also supported
*1 The camera requires a global IP address in 4G-LTE/3G mode for RTSP/RTP connection.
*2 Subscription to Zixi services required.
