Three ¼-inch Progressive CCDs - Three newly developed ¼-inch progressive scan CCDs—one each for red, green and blue—provide rich, accurate colors. To separate primary colors, JVC has incorporated a high accuracy Fujinon glass prism and proprietary mounting technology.

Spatial Offset Technology - The Red and Blue pixel locations are shifted relative to Green, allowing the sampled luminance information to be significantly increased in both horizontal and vertical directions. This results in much higher resolution images without sacrificing sensitivity.

Fujinon 10:1 Zoom HD Lens - features 3 aspheric elements which minimize the weight and space required, while producing less distortion, ghosting, and flare. Focus is controlled manually or automatically. A smooth servo zoom is controlled with a conventional rocker on the handgrip, or manually on the lens. For close-up shooting, a macro mode allows for shooting subjects as little as 2-inches away from the lens. Exposure (iris) is automatically or manually controlled, letting the shooter adjust the depth of focus by selecting the appropriate F stop. The current F stop is displayed in the viewfinder in the manual mode.

Optical Image Stabilization - advanced JVC-developed (OIS) system provides effective camera-motion compensation without any of the quality loss associated with digital image stabilization systems.

Newly Designed 1080p Digital Processor - processes all images as full 1920x1080 progressive signals, providing the maximum image information to work with regardless of the actual recording mode that is used. Also integrated into the chip are five digital noise reduction technologies that evaluate the signal and apply the appropriate compensation while increasing vertical resolution by about 30%.

35Mbps MPEG2 Encoder - Drawing from its experience in developing rack mount encoders used by major television stations, JVC developed a proprietary codec capable of providing highly efficient compression up to 35 megabits per second, a bitrate that can support full 1920 x 1080 encoding. This is significantly higher than the data rates used in other hand held camcorders and results in recorded images of exceptional quality. MPEG2 long GOP is the most widely accepted broadcast standard compression supported by all popular editing systems and broadcast servers.

HD Signal Formats - the GY-HM100 supports all major HD signal formats including 1920 x 1080, 1440 x 1080 and 1280 x 720.

Native File Recording - incorporates JVC's Native File Recording technology that stores video in the ready-to-edit format used by Apple's Final Cut Pro™ non-linear editing system. The ".mov" files created in the camera can be easily dragged onto the NLE timeline without conversion or rewrapping, saving time while keeping the recorded material first generation. There is no need to use an intermediate codec.
The camera can also store files in the ISO Base Media File Format (.MP4 MPEG-2 Long GOP), compatible with all major non-linear editing systems. In this mode, the files and folders are recorded so that they can be easily accessed in the post production process.

Secure Digital High Capacity (SDHC) Memory Card Recording - 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.

Still Picture Capture Capability - Create 2 megapixel still images (1920 x 1080) with either a live grab, or from recorded video. Since the CCDs are progressively scanned, still images are crystal clear, even if there is motion in the scene.

LCPM Uncompressed Audio with Manual Controls - The GY-HM100 records audio as uncompressed LPCM data in both Final Cut Pro™ and .MP4 formats. 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.
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 1.4kgs, 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.
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.
