Spot Exposure Meter

When shooting high-contrast scenes, setting the exposure accurately can become tricky. The Spot Meter allows you to monitor the dynamic range of the image in various ways so that the

exposure may be controlled more accurately. A manual mode allows a specific area of the image to be monitored for precise exposure control of the main subject in the frame. There are four 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 and gamma).

Remote Camera Control Connector

The GY-HM790U is equipped with a standard JVC 6-pin TTL interface for an optional remote camera controller (RM-LP25U, RM-LP57U or RM-LP55U). These units provide extensive control options, including paint, iris, gamma level, knee, gain, shutter, and black level.

Variable Frame Rate Recording (Over Crank, Under Crank)

When recording in the 720p 35 Mbps 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.

Versatility and Quality of Output

SDI and IEEE1394 Output

In addition to SD composite and HD/SD component video output, the GY-HM790U is equipped with SDI and IEEE1394 outputs.

The SDI output is via a BNC connector and can be switched between HD and downconverted SD with embedded uncompressed audio. The IEEE1394 output is via

a 4-pin connector and can also be switched between HD and SD by menu.

The audio output is HDV compliant in HD mode and DV compliant in SD mode.
