  • 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:
  • 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
  • Network Connectivity for Next-Level Functionality:
  • GY-HM850 is equipped with a USB 2.0 host connector that supports an optional wired or wireless (Wi-Fi) network adapter, or a broadband 3G/4G USB Stick

  • Secure File Transfer Protocol (FTP) built-in:
  • FTP is a standard network protocol used to transfer recorded clips from the camera to a remote file server, or "cloud"
  • Settings for up to four FTP servers are stored in the camera
  • Any of the video clips may be transferred individually or in batch mode
  • Transfer time is determined by the connection speed to the network or internet and by the size of the file(s) to be transferred
  • For example, a 30 second HD clip recorded at 720p/19Mbps may be transferred in about two minutes using a 4G connection assuming an average upload speed of 5 Mbps
  • If the clip is recorded in the "web friendly" proxy mode, it may only take a few seconds
  • Unwanted information may be trimmed from clips with basic in-camera editing, creating shorter files for transfer
  • FTP transfers may be performed in the background, allowing the operator to continue shooting without interrupting the workflow
  • Secure FTP transfers using SFTP or FTPS protocols are possible
  • Compact Shoulder Form Factor:
  • Weighing only 10.6 lbs including lens, viewfinder, microphone and battery, the GY-HM850 rests comfortably on the right shoulder providing stable, steady shots

  • The handle has been designed for better carrying balance, and to accommodate wearing gloves in cold weather
  • High resolution LCOS viewfinder
  • 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
  • Its sturdy reinforced die-cast aluminum chassis and LED light source ensure years of trouble-free operation
  • The viewfinder's native aspect ratio is 16:9
  • Safe area indications are available for popular aspect ratios including 2.35:1
  • In the record mode, audio level indications, battery remaining "fuel gauge" (when using digital batteries) and estimated time remaining for each memory card are displayed in the viewfinder
  • The Zebra function offers 2 patterns (selectable)
  • Large 4.3-inch flip-out LCD panel:
  • Complementing the high resolution viewfinder is a large LCD flip out monitor that can be used in recording, playback, clip management, and menu operation
  • The 4.3-inch 800 x 480 WVGA LCD offers a 16:9 aspect ratio and provides a wide array of monitoring and setup indications
  • It is specially designed to reduce surface reflections and glare to maintain a clear, visible, bright view during outdoor recording

  • Cross-key control makes menu navigation a breeze
  • The interface is very intuitive, with up down/left-right buttons on the same control disk
  • Selections are made by pressing the center of the disk
  • When in the camera mode, a blue LED lamp outlines the disk. When in the media playback/management mode, the color changes to green
  • Extensive image customization is available. Thanks to the oversize monitor screen, the user see changes to the image as the setting is being made, eliminating guesswork
  • Frequently used settings may include skin tone detail, color matrix, gamma, knee, black toe, compress, stretch, detail, safety zone and others
  • Individual user settings are stored on an SDHC card and may be restored to any GY-HM850 or GY-HM890 camera
  • Spot Exposure Meter:
  • When shooting very high contrast scenes, the Spot Meter can be a very useful tool, letting the videographer monitor the dynamic range of an image on the LCD/VF and adjust the exposure of an object in the frame
  • There are 4 modes of spot metering: Max/Min, Max, Min, and Manual. In the Max/Min mode, the highest and lowest levels of the image are identified with color markers, red (H) and white (L), along with the video level (before knee & gamma)
  • The same values can be obtained individually with the Max and Min settings. Manual lets the videographer set the portion of the image to monitor
  • For example, in a scene with varied illumination, the videographer may wish to meter an individual's face, and set the exposure accordingly
  • As the scene changes, the exposure can be corrected precisely to the desired subject
  • 4-Channel Audio System:
  • GY-HM850 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
  • Versatile input switching and independent channel assignment allow both mic and line-level sources (such as wireless receivers) to be connected, and phantom power is available on each XLR connector independently
  • Audio recording levels are controlled automatically or manually, with an audio level meter in the viewfinder and LCD monitor for easy monitoring
  • "FOCUS ASSIST" function:
  • Achieving exact focus with HD signals is critical
  • JVC's Focus Assist turns focusing into a fast, easy and accurate process When Focus Assist is activated, the picture in the viewfinder becomes monochrome and all objects which are in focus take on a colored edge
  • Focus Assist works equally in the viewfinder as well as on the LCD panel
  • The Focus Assist function can be invoked by pressing the dedicated button on the control panel, or assigned to the RETURN button on the lens
  • Simultaneous HD/SD-SDI, HDMI Output:
  • For live broadcast applications, or for monitoring, the GY-HM850 provides an uncompressed, 4:2:2 full HD or downconverted SD signal via its HD/SD SDI connector
  • An HDMI connector outputs the same signal as the HD-SDI connector, especially useful for monitoring while shooting a live event
  • The HDMI output may be switched to RGB mode when monitoring via computer
  • The signal can come from either the camera or from memory playback
  • When downconverted, the video may be in either PAL or NTSC depending on the HD mode selected: 60Hz (23.98p, 29.97p, 59.94p/i) = NTSC, 50Hz (25p, 50p/i) = PAL. When 23.98p modes are selected, it will contain Varicam flags (720p24 mode only) to facilitate post production
  • The HD/SD SDI output is via a BNC connector and includes embedded uncompressed audio
  • It is also possible to output the menus and clip viewer via the HD/SD SDI output
  • Genlock Input and Time Code In/Out:
  • For multi-camera productions, the GY-HM850 provides a genlock input and TC input/output
  • Time codes can be preset from within the GY-HM850's menu, or can be input from an external time code generator, useful in isocam recording applications
  • The GY-HM850 can also be used as a master TC generator, providing a time code output for other cameras or audio recorders to synchronize to
  • When using the KA-F790 fiber transceiver, external time code may be provided from a master generator at the base station and becomes available through the camera's time code output as well as for iso recording onto SDHC cards
  • Pre Rec (Retro Cache) Start Mode - No more missed shots:
  • How many times have you missed a crucial moment because you didn't hit the record button in time?
  • In this mode, the GY-HM850U continually records up to 10 seconds in cache memory. When the trigger is pressed, the live signal is appended to the cache recording, giving you a head start in getting the shot
  • This feature is invaluable in capturing breaking events when the shot would be lost before a traditional camera could begin recording
  • Interval (time-lapse) Rec:
  • This feature allows you to record single frames at set intervals, which can be used to shoot slow-moving scenes, such as sunsets or construction, or to capture time-lapse recordings such as the growing of plants
  • Variable Frame Rate Recording (Over Crank, Under Crank):
  • Variable frame rate recording enables beautiful slow motion and quick motionimage recording such as over crank and under crank
  • Using different frame rate settings for recording and playback, videos captured at normal speed are played back more smoothly than those inlow or high speed playback
  • Supports two types of wired remote control units:
  • In addition to JVC's original 6-pin remote terminal, the GY-HM850 is also equipped with a F2.5mm stereo jack remote control terminal for operating the camcorder remotely
