GY-HD250ProHD Compact Shoulder Camcorder (HDV/DV Input/output)

3.5" LCD display panel*

This 250,000-pixel 3.5" color TFT LCD monitor provides a high- resolution image during shooting and playback. JVC’s own developed Focus Assist control (see this page) ensures fast and easy focusing. A push button selects three display modes:

1.Video only

2.Video images with text information

overlay including time, status, mode and other data are shown on the screen.

3.Only information such as time, status, mode, time code, audio levels and other data is shown on the screen. When the LCD display panel is in this mode, the viewfinder can also be used.

Various audio-related functions

When color bars are output, an audio reference level (test tone) can also be output if required. This is set via the menu. The audio reference level can be set at -12 dB or -20 dB as required. To minimize extraneous noise picked up by the microphone, a "wind cut" function is provided.

User-friendly design

Universal ergonomic design

The GY-HD250 has multiple adjustments to provide a comfortable positioning of the camera, such as a shoulder pad that can be moved back and forth, a viewfinder with an eyepiece that can be adjusted left and right as well as back and forth, and a padded audio monitor that

adjusts up & down.



Patented “FOCUS ASSIST” function

A JVC-patented feature, Focus Assist, turns focusing into an easy, fast 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 color fringe. In addition to the factory default Middle position, Low and High positions are available. In the Low position, you can limit the area in focus for more precise focusing. This is particularly helpful when using the technique of pulling focus. Focus Assist works equally in the 0.44" viewfinder and the 3.5” LCD panel. There are two Focus Assist buttons, one for each of handheld and shoulder operation.

Genlock

This camcorder has genlock input capability for synchronization and time code input/output, making multi-camera shooting possible. For synchronization, BB or VBS signals (SD) and HD tri-level sync signals (HD) are available to lock to various components, including external audio recorders, other cameras and switchers. In addition, H Phase (HD/SD) and SC Phase (SD only) can be adjusted

Versatility and flexibility

Camera settings recorded on SD card

Customized settings can be stored on a standard SD memory card and loaded into another GY-HD250 or changed on site, as required.

IEEE 1394 interface/HD-SDI output interface

A convenient IEEE 1394 interface allows easy direct connection to NLE systems or to a PC for capturing, editing and archiving.

An HD-SDI (High Definition Serial Digital Interface) is also provided to enable transmission of uncompressed digital HD signals via co-axial cable. Since the HD-SDI interface can use existing SDI (Serial Digital Interface) cabling, configuring studio applications is greatly simplified.

 



Out-of-focus image

In-focus image

 

The edge of the in-focus subject is

 

shown in color, telling the operator that

 

the subject is in-focus. A major benefit of

 

this system is that it operates in real time.

Shutter angle display mode

In addition to the conventional second-unit indication for shutter values, a shutter angle display mode is available. This makes it easy for all users — including those more familiar with film cameras — to set the shutter value.

Connect to optional external HDD

The camcorder has a hard disk drive accessory option, DR-HD100, which connects via the IEEE 1394 port, allowing footage to be edited immediately without having to wait for data to be transferred.

DR-HD100 Hard Disk Drive incorporating the latest DTE (Direct to EditTM) technology

Interface to GY-HD250 camcorder

The DR-HD100 has been designed specifically to interface with the GY-HD250 camcorder via IEEE 1394. Interlocked to the camcorder’s record trigger, HD and SD images can be recorded together with audio and time code. It can be powered by either a built-in rechargeable or external battery. The DR-HD100 is supplied with its own cradle, from which it can be detached easily. Optional brackets are available for mounting the HDD recorder to the rear of the camcorder.

Compatibility with NLE systems for HDV and DV editing

DTETM technology permits the DR-HD100 recordings in HDV and DV to be set to the NLE’s native file format. This means that no time is lost due to the lengthy processes of file transfer and conversion. The

DR-HD100 can be used with most popular editing applications from Adobe, Apple, Avid, Canopus and many more*. As new application support is released, the DR-HD100 can be updated in the field with new system software easily by connecting the disk drive to a computer.

*NLE Dependent

Integrated with camcorder and disk drive operation

Attached with the GY-HD250, the DR-HD100’s record and record/pause functions are controlled from the camcorder. Time code generated by the camcorder is recorded to files on the DR-HD100, and recorder status and other information can appear in both the viewfinder or LCD display.

Long record times

This hard disk drive option extends uninterrupted record time by many hours. For example, a 40GB FireWire drive can store 3 hours of DV video and 4 hours of HDV video, and 80GB drive does twice these times. It is also possible to daisy chain up to four external drives of different capacities to the DR-HD100, enabling uninterrupted recording of extremely long duration.

LCD display and playback modes

The DR-HD100 features a detailed LCD that displays the system mode, time code and disk space remaining. Video clips can be reviewed in the viewfinder, LCD panel or external monitor, by using DR-HD100’s playback mode. Functions include record, play, pause, stop, forward index, back index and multi speed fast forward and rewind.
