News acquisition is changing, with more emphasis being placed on immediate electronic delivery. JVC is responding with the GY-HM650, the world's first ProHD handheld news camera equipped with dual codecs, built-in FTP and optional Wi-Fi connectivity for shooting and delivering news footage faster than ever. JVC's revolutionary new dual codec design makes it possible to record in two resolutions on separate memory cards—one in full HD and one as a smaller web-friendly file. Smaller files can be quickly and easily transferred with built-in FTP—even while recording.* And, Wi-Fi connectivity lets you control the camera, add metadata, and even remotely view the live signal from a personal computer, tablet or even a smartphone.
Effective with the 4.0 upgrade (available June 2015), the GY-HM650 adds significant new capabilities to its streaming functionality. When streaming with Zixi advanced error correction, Adaptive Bitrate Control provides stable streaming by varying the bitrate depending on network conditions. High speed streaming at 12 Mbps UDP (or 5 Mbps, Zixi) is now possible for production quality results. Advanced content-aware error correction tolerates up to 30% packet loss and makes it possible to perform streaming under adverse conditions. It is also now possible to stream directly to a content delivery network (CDN) such as YouTube thanks to the implementation of RTMP protocol. This makes it possible to stream directly to a worldwide audience at the touch of a button, and without any additional hardware in the field, except a modem!
But the GY-HM650 advantages don't end with its wireless connectivity. With a newly developed 23x Fujinon lens and three full HD 1/3-inch CMOS sensors, the GY-HM650 produces image quality that surpasses many larger and more expensive cameras. And with flexible solid state recording options, including a new Extreme High Quality(XHQ) mode (H.264 at 50 Mbps), your recordings are stored at the highest quality and are compatible with a wide range of post production workflows.
High Performance Full HD 1/3-inch CMOS Sensors
At the heart of the GY-HM650 are three, 1/3-inch CMOS sensors, each capable of capturing full HD 1920 x 1080 resolution images. Offering an excellent sensitivity of F11 (60Hz) /F12 (50Hz) and a remarkable signal-to-noise ratio, the devices provide superior precision and color reproduction.
Newly-developed 23x Fujinon Auto Focus Zoom Lens with Manual Functions
The GY-HM650 is equipped with the newly-developed Fujinon wide angle 23x zoom lens, giving the highest magnification in the industry. Delivering superior low-light performance and ensuring brightness at the tele end, the lens offers F1.6-3.0, a focal range of 29mm-667mm (35mm equivalent) and includes servo zoom, manual focus, and iris rings, along with a four-position (clear, 1/4, 1/16 and 1/64) ND filter. Other features include an optical image stabilizer, chromatic aberration correction. The GY-HM650's long zoom range means that you can get shots not possible with other cameras its size.

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-HM650 utilizes dual codec FALCONBRID™ processors that make it possible to record in two resolutions—one in full HD and one as a smaller web-friendly file onto separate memory cards. Depending on connection speed, the smaller files can often be transferred faster than real time for delivery to websites or file-sharing services. With dual processors it is also possible to stream live video at one resolution while recording at another resolution and bit rate.*
MPEG-2 and AVCHD Recording
The GY-HM650 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 a wide range of 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-HM650 now also supports simultaneous HD/SD or HD/proxy 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 1.2 Mbps SD format
Ultra and Extreme High Quality Recording Modes
The GY-HM650 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-HM650 further provides the H.264 Ultra High Quality (UHQ) 35Mbps recording mode, again offering superior image quality but with smaller file sizes.
The XHQ mode is available with the 3.0 upgrade (May 2014).
FLEXIBLE FILE-BASED WORKFLOW
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™. JVC has eliminated one of the main obstacles to achieving a smoother, more streamlined production workflow. 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.Additionally, with the MPEG-2 mode for Windows editing environments, it is possible to record in MP4 format (XDCAM EX™ workflow-compatible) for direct editing in other major NLE systems, including Avid Media Composer, Adobe Premiere and Grass Valley Edius Pro.
*H.264 SD MOV file can be edited by Grass Valley Edius Pro
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.) It's fair to say that JVC's implementation of MXF, MOV, MP4 and AVCHD makes the GY-HM650 the most versatile and interoperable camera in the industry.
Web Friendly (Proxy) file formats- Lower resolution H.264 files (480x270p and 960x540p) are recorded simultaneously with full HD files. These files are significantly smaller than HD files, and thus are very suitable for immediate posting to the web. A file recorded in the 960 x 540 mode is approximately 1/10th the size of a full HD file recorded at 35 Mbps, and therefore takes a fraction of the time to post. The smaller files may be quickly imported to an iPad for easy editing using iMovie or Pinnacle Studio. Transporting video to the web or back to the studio has never been faster.
Dual SDHC/SDXC Card Slots for Maximum Versatility- Dual SDHC/SDXC card slots make the GY-HM650 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. With the new dual codec, it is now possible to record full HD files on one memory card while simultaneously creating smaller SD or proxy files on the other, providing the flexibility for a range of workflow possibilities.
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.
* During simultaneous backup recording in HD mode, the duplicate file records in the same file format and bit rate as the original.

WI-FI AND BROADBAND CONNECTIVITY
Network Connectivity for Next-Level Functionality
The GY-HM650 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. Through connection to a LAN, WAN or internet, various wireless communications functions are available. A built-in web interface, allows remote viewing of camera images and wireless remote control when using a smartphone, tablet or PC. Importing Metadata
You can download a metadata settings file (XMLformat) from a remote FTP server and store metadata inthe GY-HM650 for recording onto video clips in the MXF format. Metadata may include TITLE (2 data fields), CREATOR, and DESCRIPTION (up to 2047 characters.) Once stored in the camera, metadata is then recorded into the MXF video clips, and will stay with the clips through postproduction, playout and archiving.Adding Metadata
In addition to downloading, metadata is added in the field using a smartphone, tablet or PC via the camera's web interface. Again, the camera records this information to the MXF video clips.Editing Metadata
Metadata on existing clips may be edited using a smartphone, tablet or PC. Using a web browser, the "Clip Metadata" screen displays a list of clips stored on the memory card with thumbnail images. Clip metadata can be edited and rewritten back to individual clips stored in the camera.Remote control and viewing with a mobile device
When using an optional WiFi or LTE adapter, you can access many of the camera's settings with a tablet, smartphone or computer giving you unprecedented remote control capabilities. Best of all, no "app" is necessary as everything is accessible using a standard web browser. The image from the camera may be also viewed independently of any streaming or recording, allowing the operator to make lens and camera adjustments live. While viewing the image, the camera's recording and streaming functions can be stopped and started and the zoom lens may be controlled. Zoom presets are also registered and deleted remotely using the web browser.
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 one minute using a 4G connection assuming an average upload speed of 10Mbps. If the clip is recorded in the "web friendly" proxy mode, it may only take a few seconds.
FTP capabilities are enhanced with version 2.0 introduction (May 2013). Unwanted information may be trimmed from clips with basic in-camera editing, creating shorter files for transfer. FTP transfers may now be performed in the background, allowing the operator to continue shooting without interrupting the workflow. Version 2.0 also adds secure FTP transfers using SFTP or FTPS protocols.
In addition to secure FTP, the following Wi-Fi security protocols are supported:

Advanced Streaming Technology- When the GY-HM650 is equipped with a high speed broadband modem, ENG crews now have a handy, economical means to deliver live field reports without the need for a microwave or satellite truck. Through its use of dual codecs, the camera offers live transmission (streaming) while simultaneously recording HD to a memory card. Transmission at selected resolutions and bitrates is possible independent of the recording mode. The GY-HM650 offers a range of streaming options from basic point-to-point to cloud streaming with advanced error correction.
Basic streaming
The GY-HM650 outputs a transport stream with TCP or UDP protocol to a decoder or computer with a fixed IP address at the receiving facility. Latency is minimal (usually under 2 seconds with UDP transmission.) Image quality is dependent on the speed/mode selected. With a good 4G, Wi-Fi, or wired connection, additional error correction may not be necessary making this the easiest and most economical streaming solution. Streams may also be "pulled" from the camera using Real-time Transport Protocol (RTP) and Real-time Streaming Protocol (RTSP).Advanced streaming with ARQ and Forward Error Correction
JVC's advanced streaming technology, powered by Zixi, utilizes content-aware error correction algorithms to compensate for packet loss common with mobile internet connections. In this mode, the decoder performs a dynamic assessment of the link capacity (link monitoring) and signals the camera to adjust bandwith and, if necessary, resend packets. The advanced error correction is able to compensate for up to 30% packet loss assuring a reliable stream even under adverse conditions. A Zixi-licensed decoder or server is required at the receiving end.ProHD Broadcaster Powered by Zixi / Cloud-based Services
Single camera point-to-point streaming to a single decoder delivers excellent results. For facilities with multiple cameras, JVC has made available the ProHD Broadcaster, the centerpiece for high quality IP video over the internet. Broadcaster is available as a physical server or cloud-based solution, and receives streams from JVC's streaming ProHD cameras and delivers those streams to various decoders and content delivery (CDN) ingest points. Broadcaster includes a wide array of video processing features, including transcoding, time shifting, VoD playout, recording functionality and stream switching. Whether phyically located on premises or in the cloud, Broadcaster offers a friendly web interface that simplifies management of multiple sources and stream destinations while providing advanced content-aware correction compatible with Zixi-enabled JVC cameras.
When directly connected to an LTE modem or Wi-Fi hotspot, the GY-HM650 provides active feedback to the camera operator with indications in the viewfinder (and LCD screen) about the status of the stream and LTE (or Wi-Fi) connection.

High-Resolution 3.5" LCD Monitor
A high-resolution 920K LCD monitor provides a wide array of monitoring and setup indications. For maximum flexibility, the 16:9 monitor is mounted at the top of the camera, and can be swiveled for handheld shooting at various angles or flipped for use as a talent monitor.
1.22 Megapixel LCOS Viewfinder- The GY-HM650 features a stunning new 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.
Focus Assist Function- Helping the camera operator stay focused on the action is a focus assist system that highlights the edges of objects in the image. When Focus Assist is switched on, the image in the viewfinder or LCD monitor switches to monochrome and all objects that are in focus appear with colored edges (selectable from red, green or blue). Keeping the important elements in the picture in focus while shooting is greatly simplified.
GUI- The GY-HM650 takes ProHD's highly regarded GUI navigation to the next level. Not only are menu items immediately accessible, but settings can also be easily checked right from the settings window. With an improved graphical interface, it's easier than ever to customize the settings to match individual preferences or the demands of the moment.
USER FRIENDLY FUNCTIONS
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-HM650U continually records up to 15 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)- When recording in the 720p 35Mbps mode, the camera can be set to record at a frame rate different than the playback rate. This capability makes it possible to record slow or fast motion when the recording is played back at 24p, 25p or 30p. The GY-HM650 can also under-crank in the 1080p 35Mbps mode.
HD-SDI / HDMI Connectivity- For live broadcast applications, or for monitoring, the GY-HM650 provides an uncompressed, 4:2:2 full HD or downconverted SD signal via its HD/SD SDI connector. 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. 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.
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.
