Recording in MP4 File Format
This camera supports recording in the MP4 file format for
Windows NLE systems, which can be utilized in a wide range
of non-linear editing environments.
Recording on SDHC Memory Card
(Class 6/10)
The absence of mechanisms with the use of SDHC (Class 6/
10) as recording media brings about increased operation
reliability. In addition, the improved compatibility with
computers enables high-speed data transfer to NLE as well
as reduction of operating costs.
35 Mbps High Image Quality Mode
This camera recorder is equipped with a 35 Mbps high quality
mode, in addition to the HDV mode bit rate (19/25 Mbps).
Wide Variety of Recording Formats
This camera recorder supports various HD formats (1080i,
1080p, 720p) as well as SD (DV) formats (480i : U model,
576i : E model), enabling it to be used under various
environments. It also supports 1440x1080 and 1920x1080
full resolution in the 1080 format.
Adoption of MPEG-2 Long GOP for Easy
Editing
Shortens editing and output time by adopting MPEG-2
codec, which puts less stress on the editing computer.
High Resolution via Triplex Offset
2.5k x 1.4k pixels are generated with the Triplex Offset, and a
high resolution of more than 900 horizontal lines and 1000
diagonal lines is achieved using the proprietary front
processing.
Spot Meter Function
The brightest and darkest positions on the screen are
automatically detected and displayed together with the
dynamic range. As this is a pre-gamma value, it allows you to
understand the lighting ratio and prevents overexposure or
underexposure in shooting scenes where lighting is
controlled.
High Resolution Viewfinder
With a high resolution of 852 x 480 in 0.425 inches, the
viewfinder is now more robust and enables more accurate
focusing.
High Resolution LCD Monitor
Equipped with a 4.3inch 800x480 large LCD monitor, both
shooting precision and viewing performance are improved.
Intuitive User Interface
The sophisticated user interface allows more intuitive
operations. Thumbnail display is also available for you to
easily select a recorded clip for playback.
Compact Shoulder Style
By inheriting the compact shoulder style from the GY-HD100
series which is widely accepted in the industry, more stable
shooting can be done on this camera recorder while its
weight remains similar to that of a handheld camera
recorder.
Lens Interchangeability
Existing lenses can be used, thus saving on costs. You can
also select the most appropriate lens according to your
shooting requirements.

Precautions for Proper Use
(continued)

7
Others
䡵Do not insert objects other than the memory card into the
card slot.
䡵Do not block the vent on the unit.
Blocking of the vent causes internal heating and may lead to
burns and fires.
䡵Do not turn off the [POWER] switch or remove the power
cable during recording or playback.
䡵The camera recorder may not show stable pictures for a
few seconds immediately after the power is turned on, but
this is not a malfunction.
䡵When the video signal output terminals are not in use, put

䡵Do not drop this unit or subject it to strong impact or
vibration as it is a precision equipment.
䡵Optical performance of lens
Due to the optical performance of the lens, color divergence
phenomena (magnification chromatic aberration) may occur
at the periphery of the image. This is not a camera
malfunction.
LCD Monitor and Viewfinder
䡵The LCD monitor and viewfinder screens are
manufactured using high-precision technology. Black spots
may appear on the LCD monitor and viewfinder screens, or
red, blue, and/or white spots may not disappear. However,
this is not a malfunction and these spots are not recorded on
the SDHC card.
䡵If you use this unit continuously for a long period of time,
the characters displayed in the viewfinder may temporarily
remain on the screen. This is not recorded on the SDHC
card. They will not appear after you turn the power off and
then on again.
䡵If you use this unit in a cold place, the images may appear
to lag on the screen, but this is not a malfunction. Retained
images are not recorded on the SDHC card.
䡵Do not press against the surface with force or subject it to
strong impact. Doing so may damage or break the screens.
䡵Noise may appear in the viewfinder when switching
between the live video and playback images.
䡵Due to the characteristic of the viewfinder display device,
colors may appear on the images when you blink your eyes.
This is not a malfunction. It does not affect the recorded
images, SDI output, or component output.
Characteristic CCD Phenomena
䡵Smear and blooming
Due to the physical structure of CCDs, vertical streaking
(called “smear”) may occur when shooting an extremely
bright light source or expansion of light (called “blooming”)
may appear around it. Although the CCD employed in this
unit produces very little smear or blooming, these
phenomena may still occur when shooting a bright light
source.
䡵Moire or aliasing
Stripes, lines or other fine patterns may appear jagged when
they are shot.
䡵White dots
High temperatures can cause CCD sensor pixels to produce
white dots in the image. This is especially prominent when
boosting the sensitivity.
This is a characteristic of the charged-coupled device (CCD).
As far as possible, use this unit under conditions where the
temperature of this unit does not increase.
