The central part of a DV camcorder is the CCD, or
Charge Coupled Device. This sensor creates a video
picture by recording the light intensity to recognize
an image or shape, along with the color levels to
reproduce a full color picture.
There are several tape based DV camcorders that have
both color eyepiece viewfinders and a flip out TFT
LCD screen to view the action as well as the previous
recorded footage. Most tape-less models however,
only offer the TFT screen to preview your captured
video and to view while you make a recording.
When you need to get closer to the action, a zoom
lens can be a great feature. Don't get swayed by
the digital zoom figure however; as no matter how
large it may be, you should always base your final
decision on the optical zoom.
The optical zoom will give you a true indication of
the video image, where digital zooms interpolate the
available pixels to zoom in on an image. Optical
zooms will normally range around the 10X mark, with
digital zooms ranging from 100X and above.
The auto focusing systems are great as well, although
manual focus options can be ideal for low light or
when focusing on a subject against a landscape. Being
available on most video cameras, the manual focus
control can be found as either a ring on the lens
or as a dual button system on the body.
Most video cameras these days will provide a tilting
feature in the camera itself, although this feature
should be avoided unless you don't intend to edit
the video on a computer. The title effects on
many cameras are quite limited and cannot be
removed afterwards.
Almost all new high definition video cameras will
use a rechargeable Li-ion battery, even though a
spare battery might be useful as the batteries are
unique to each camcorder maker and normally each
model.
Most of the latest cameras allow you to capture
digital still images onto a removable flash memory
card. The most popular media is SD or MMC, but
Sony and Samsung cameras often capture to a memory
stick.
If your video camera doesn't offer still image
capabilities, you can always perform a capture of
the screen in your editing program. Always remember
that the image resolution when capturing a still
this way will always be 640X480, which is actually
less than 1 MB, or Mega Byte.
Canon XLH1
On September 18 of 2005, Canon broke new ground in
the digital video camera industry, announcing the
XL H1, which was Canon's first DVC featuring high
definition. Originally developed based on the needs
of professional and enthusiast videographers, the
XL H1 retains the operability of Canon's very popular
XL2 while increasing the professional function and
supporting high definition recording.
The flagship DVC for the company of Canon, the XL H1
is ideal for use all across the spectrum of
professional content making, from film and television
production to filming weddings. The XL H1 also
comes equipped with a HD 20X zoom video lens, the XL
5.4-108 mm L IS II, which contributes to Canon's
development aim of delivering the highest possible
quality of recording available today.
As Canon's first HD video camera, the XL H1 camcorder
and 20X HD video zoom lens will provide broadcasters
with a low budget 1080i resolution option for ENG,
documentary or even reality television productions.
Film makes will also fall for the extensive Cine
controls and 24 frame rate option the XL H1
has to offer. Canon's custom jackpack features
include uncompressed digital HD-SDI output for
seamless integration into broadcast studios or high
quality image transfer to non linear editing systems.
The genlock feature will allow movie sets to
easily synchronize camera settings across multiple
camcorders and SMPTE time codes will allow for
streamlined tape and edit management.
The XL H1 also offers three 1/3 inch 1.67 megapixel
interlaced CCDs that capture images at 1080i
resolution. It also features selectable frame
rates of 50i and 25F, so capturing fast motion and
just about everything else is possible with the
XL H1.
