and SD images can be recorded together with audio and time code. It
is powered by either a built-in rechargeable or an external battery. The
DR-HD100 is supplied with its own cradle, from which it is detached
easily. Optional bracketry is available for mounting the HDD recorder at
the rear of the camcorder.
Compatible with popular NLE systems for HDV and DV editing

TM
DV to be set to the NLE's native file format. This means that no time is
lost to the lengthy processes of file transfer and rendering. Use DR-

Avid, Canopus and many more. As new application support is
released, the DR-HD100 can be updated in the field with new system

Patented "FOCUS ASSIST" function
A JVC patented device, 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 coloured 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.
Out-of-focus image
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.
Other features
Two XLR audio inputs
Full Auto Shooting
Adjustable colour matrix
LCD mirror mode
record/pause functions are controlled from the camcorder. Time code
generated by the camcorder is recorded to files on the DR-HD100 and
DR-HD100 status and other information appears in the viewfinder and
LCD display.
Long record times
This hard disk drive option extends uninterrupted record time by hours.
For example, an 80GB FireWire drive can store 6 hours of DV video
and 7.5 hours of HDV video, and a 40GB drive does half these times.
It is possible also to daisy chain up to four external drives of different
capacities to the DR-HD100, enabling uninterrupted recording of
incredibly long durations.
LCD display and playback modes
The DR-HD100 features a detailed LCD that displays system mode, time
code and disk space remaining. When used with the GY-HD251
camcorder, clips can be reviewed on 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.
