JVC GY-HM100 전단

Apr-Jul 2009

JVC has just introduced the GY-HM100, a break-through

hand-held ProHD camcorder that records in native Apple

Quicktime .mov file format directly to SDHC memory cards.

The camera is tiny; it fits in the palm of your hand. But the idea

is big. After shooting (up to 50 minutes of 1080p onto a 16GB

SDHC Memory Card, you can begin editing almost immediately

by simply dragging and dropping the files into Final Cut Studio.

Anyone who has wrangled or archived the baffling array of

AVCHD and other hierarchical file formats will doubtlessly

order one of these camcorder immediately for the sheer joy of

having one file per scene.

The GY-HM100 ProHD camcorder records Quicktime files

directly to those little SDHC solid state memory cards you see in

most still cameras. Solid state prices have dropped to the point

where recording 50 minutes of 1080p can now be less expensive

than tape, and...sound the trumpets...it’s so cost effective you

would be foolish not to archive those SDHC cards as digital

masters.

Since files can be recorded in Quicktime, the native .mov files

could actually be edited directly from the solid state memory

card with Apple’s Final Cut Studio. But, you might prefer a

more elegant aproach. There are (more angelic trumpets) two

SDHC slots on the camcorder. So, when one card has filled

up, you eject it, and either hand it off to your assistant/data

wrangler/mini-DIT or do it yourself: copy the files into your

laptop. Since, at last unofficial count, 99.9% of the readers of

Film and Digital Times are on Mac, we’ll assume you’ll copy the

files onto a MacBook Pro with an SD to Express Slot adapter

(Sandisk SDAD109A11 Digital Media Memory Card to Express

Slot Adapter) or with an SD card to USB adapter.

Meanwhile, you can still keep shooting, since you’ll record

to the other slot in the camcorder. “Traditionally, camera

manufacturers have designed their products expecting NLE

vendors to conform to proprietary or generic file formats

JVC GY-HM100 ProHD 1/4" Camcorder

resulting in an extra and often time consuming step when

preparing to edit,” Craig Yanagi explained. “Files created in the

GY-HM100 can be edited immediately without conversion. It’s

truly the first camcorder designed for post production.”

The JVC GY-HM100 ProHD camcorder weighs 3.1 lbs. It uses

three progressive scan ¼” CCDs and records at data rates up

to 35 Mbps in 1080/24p, 1080/25p, 1080/60i, 720p and much

more. SDHC Class 6 memory cards must be used. (Class 6 refers

to data rate: the higher the number, the faster it is. Many still

camera SDHC cards are Class 4 or below. SDHC cards that are

not up to class 6 specifications cannot be used with either the

GY-HM100 or GY-HM700).

The GY-HM100 comes with an integrated high definition

Fujinon 10:1 lens, f1.8, 3.7-37 mm. It has manual and automatic

control of focus and iris. The lens is made with three aspheri-

cal elements and a new anti-reflection coating. A retractable

cover is built into into the lens hood, eliminating the need for a

traditional lens cap. JVC’s Focus Assist displays the viewfinder

or LCD image in monochrome with colored edges.

With tapeless recording to dual 64GB SDHC Class 6 memory

cards, you have enough for up to 6 hours of continuous HD

recording at 720p in SP mode (25 Mbps) and up to 3 hours, 20

minutes at 1080p in HQ mode (35 Mbps) . The camera automat-

ically begins recording on the second card when the first card

is full.The cost per-minute of SDHC media is comparable to, or

less than, professional video tape.

JVC developed a proprietary codec capable of providing highly

efficient compression up to 35 megabits per second, with

MPEG2 long GOP encoding. The Quicktime .mov files created

in-camera can be dragged onto the NLE timeline without

conversion or rewrapping.

The camera also stores files in what the specs say is an ISO Base

Media File Format (.MP4), compatible with all major non-linear

editing systems. We are advised to use the ProHD Log and

Transfer Plug-in for Final Cut Studio to deal with these files—

but why would we if the .mov files are so much simpler and

faster to deal with, and don’t require rewrapping?

The audio recording features of the GY-HM100 include two

channels of uncompressed LPCM audio with manual level

controls and audio meter. Balanced XLR inputs with phantom

power are provided on the handle for an external microphone

and/or wireless receiver. A 2.8-inch LCD display, in 16:9 aspect

ratio, provides a wide array of monitoring and setup informa-

tion. There’s an infrared wireless remote and you can capture

2 megapixel still images from either a live framegrab or from

recorded video.

The GY-HM100 is scheduled for delivery in April 2009. For
