The GY-HM100U is a Compact Handheld camcorder with performance and features found only in larger and more expensive models. It’s designed to be easy to use, making it ideal for news reporters and producers. Seasoned shooters will find that its small size lets them work in environments where larger cameras would be impractical—all while producing recordings on par with broadcast cameras.

The GY-HM100 records on widely available SDHC Class 6 memory cards, presently available in capacities up to 32GB. The camera provides 2 memory card slots, for a total of up to 64GB of on board storage—enough for more than 6 hours* of continuous HD recording. (The camera automatically begins recording on the second card when the first card fills up.) Being able to quickly switch cards with dual slots is invaluable in a breaking news situation where a producer may wish to begin editing while the shooter is still capturing footage. 
The GY-HM100 records 2 channels of uncompressed LPCM (linear pulse code modulated) 16 bit audio sampled at 48Khz. Audio levels can be controlled manually, or automatically using AGC. An audio meter is provided in the LCD and VF displays to facilitate adjustment. Balanced XLR connectors are provided on the handle for an external microphone and/or wireless receiver. 48V phantom power is available for each microphone. Versatile input switching allows the microphone signal to be directed to the desired channel. A shotgun microphone is provided, as well as a built-in stereo microphone for ambient sound pickup.
| Operational / Ergonomic Features |
- Compact Hand-held Form Factor
- The GY-HM100 is the smallest pro format 3-CCD camcorder available–about the size of the lens of a 2/3-inch camera. At only 3.3 lbs, it can be used comfortably for hours, and without the need for clumsy support bracing. Its size makes it ideal for hand-held POV use and for applications where a full size camera would be impractical such as traveling into potentially hostile situations. For a smaller footprint and less conspicuous shooting, the handle can be easily removed. When media needs to be concealed, Micro-SDHC memory cards can be used with a card adapter.
- Shooter-friendly controls and layout
-
The camera’s hand grip has a comfortable, familiar feel comfortably accommodating hands of all sizes. Controls and switches are right where you’d expect them. To conserve on space, a single ring is used for both manual focus and manual zoom. When holding the camera by the grip, zoom and trigger controls operate the same as on full size cameras. Available controls on the camera body include:
- Lens zoom/focus selector
- White balance—selectable between preset and 2 user settings.
- Auto white set
- Gain (L,M,H)
- Full auto (on/off)
- Auto/Manual focus
- ND filter (in/out)
- User1/User2/User3
(allows user to predefine functions such as Focus Assist, Color Bars, TC setting, LoLux, Zebra, Tele/Macro, etc.) - Select Memory Card (A/B)
- Iris (manual/auto)
- Shutter (Shutter priority, set)
- Record start/stop

- Mic/Line CH1/CH2 select switches

- Display
- Patented "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 fringe. Focus Assist works equally in the viewfinder as well as on the LCD panel. The Focus Assist function can be assigned to one of the three USER buttons.
- Versatile Manual Controls
- When operating the camera in the manual mode, depth of field can be adjusted by manually setting the iris. Aperture priority automatically selects the correct shutter setting based on the iris selection. Shutter can be manually adjusted from 1/4 to 1/10000 sec. Other manual adjustments include:
- LoLux mode — a JVC exclusive feature that permits shooting in adverse lighting conditions
- H detail & V detail Adjustment
- KNEE Setting (AUTO/LOW/MID/HIGH)
- Zebra pattern which range specification is possible
- Color matrix/Gain Adjustment
Gain settings of 0,3,6,9,12,15,18 dB & ALC can be assigned to the "L/M/H" gain switch - Gamma Adjustment which gives rich expression of gradation
- Data Battery
- When used with JVC Data Batteries, the remaining battery power by percentage and remaining recording time in minutes can be checked with the touch of a button, even while the camera’s power is off. One BN-VF823U Data Battery (7.2V, 2190mAh) is provided for recording time over 2 hours.
- 2.8-inch LCD Display
-
The 2.8-inch LCD offers a 16:9 aspect ratio and provides a wide array of monitoring and setup indications. It is especially designed to cut surface reflections and glare to maintain a clear, visible, bright view during outdoor recording. Menu items are easily selected using a small joystick and push buttons. - Wireless Remote Control
- A simple infrared remote control unit (provided) allows the camera to be operated remotely. This is especially useful at events when the camera is used to capture POV shots when an operator is not available.
