High Definition Has Arrived
A although back, Sony, Sharp, Canon and JVC announced
the creation of a new high definition video regular
for video cameras – HDV. HDV utilizes MPEG-2 image
compression having a definition of 1080 lines and a
16:9 aspect ratio.
Shortly soon after that, Sony opened the door to high
definition by making the very first HDV camcorder, the
HDR-FX1. This release was on par with the launch
of the very first DV camcorder in 1995, which at the
time was a giant step forward for image top quality,
marking the break from conventional analog.
At the time, consumers had been moving from the Hi8
format to DV, which featured significantly superior image
good quality, along with the capability to transfer to a
pc with out any degradation of signal. With
HDV, the resolution of camcorders could be doubled,
from 576 lines to 1080. The compression strategy is
no longer DV, but MPEG 2 instead.
HDV exists in two formats – 1080i (interlaced) and
720p (progressive). With interlaced, the video
camera records 1080 lines in interlaced images,
which is half images of 540 lines each that are
displayed 60 times per second.
With 720 progressive, the video camera records
720 lines in progressive images, that are full
images that are displayed 30 times per second.
Sony chose to use 1080i on the HDR-FX1, where JVC
chose to use 720p for the GR-HD1, which is sold
only in NTSC format within the USA and Japan.
The progressive mode format demands a television
set that supports it, even though interlaced mode is
the natural scan mode that televisions use. The
question today is which of the two formats
deliver the most beneficial image good quality.
With a number of high definition video cameras on the
market right now, the question of image high quality all
depends on the camera and functions, together with
your tv or method of play back. All high
definition video cameras are wonderful in excellent
and playback, which is why they’ve turn out to be so
well-known is such a smaller amount of time.
With Sony, JVC, and Canon continuing to develop
HDV, you know the technologies will continue to get
superior and much better. When high definition very first
hit the market, it was an instant success. With
the integration of HDV, camcorders permit you to
do what you by no means could just before.
Should you like to record precious memories, a high
definition video camera is just what you will need. They
are really handy to have around, and you will discover
various on the market today for you to select
from – all you’ll need to do is pick the top 1
for you.
