Canon 14x HD Lens
The JVC GY-HM790U comes equipped with a
14x interchangeable HD lens from Canon.
With a focal length down to 4.4 mm (equivalent
to 31.7 mm on a 35 mm camera), the new lens
is 20% wider than previous models, and at the
telephoto end (up to 447 mm at 35 mm equivalent) it is less
susceptible to color flaring. Focus accuracy is maintained throughout
the zoom range, and the same image brightness is sustained without
reducing the F-stop.
Advanced MPEG2 High Bit Rate Encoding
1080p Dynamic Digital Signal Processor (DDSP)
At the heart of the GY-HM790U is the new Dynamic Digital Signal
Processor. Processing is performed on the full progressive 1920 x
1080 signal, regardless of the camcorder's
settings, ensuring the highest picture quality
in any shooting mode. All major HD
resolutions are supported, including
1920 x 1080, 1440 x 1080 and 1280 x 720.
JVC Proprietary 35Mbps MPEG2 Encoder (HD)
Drawing from its experience in developing transmission
signal encoders used by major television stations, JVC
developed a proprietary codec capable of providing
highly efficient compression up to 35 Mbps — high
enough to support full 1920 x 1080 encoding — capable of creating
high resolution images with minimal artifacting. The XDCAM EX™
MPEG2 long GOP (Group of Pictures) codec is a widely used,
broadcast-standard compression system and is supported by all
popular editing systems and broadcast servers.
The GY-HM790U supports all major HD signal formats including
1920 x 1080, 1440 x 1080 and 1280 x 720.

Standard Definition Recording Capability
Responding to the needs of the industry, the
GY-HM790U, in addition to its capability as an HD
recorder, offers Standard Definition recording for
maximum flexibility. Recording in SD provides
a time-saving alternative to down-conversion of HD material for SD
HD/SD
Rec
broadcasts, which is still an industry standard in many countries
worldwide. This feature offers a fundamental advantage for
professionals with time-sensitive SD workflows.

Uncompressed Audio Recording with Full
Manual Control
The GY-HM790U captures audio with the same
uncompromising quality as video. Two-channel
16-bit/48 kHz uncompressed linear PCM can be
recorded via the detachable shotgun microphone, or via a pair of
balanced XLR connectors. 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 can be
controlled automatically or manually, with an audio level meter in
the viewfinder and
LCD monitor for
easy monitoring.
