A although back, Sony, Sharp, Canon and JVC announced
the creation of a new high definition video standard
for video cameras - HDV. HDV utilizes MPEG-2 image
compression having a definition of 1080 lines along with a
16:9 aspect ratio.
Shortly after that, Sony opened the door to high
definition by producing 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 quality,
marking the break from standard analog.
At the time, buyers were moving from the Hi8
format to DV, which featured much better image
excellent, along with the ability to transfer to a
personal computer without any degradation of signal. With
HDV, the resolution of camcorders could be doubled,
from 576 lines to 1080. The compression approach 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 every which 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 make use of 1080i on the HDR-FX1, where JVC
chose to make use of 720p for the GR-HD1, which is sold
only in NTSC format inside the USA and Japan.
The progressive mode format needs a tv
set that supports it, although interlaced mode is
the natural scan mode that televisions use. The
question right now is which of the two formats
deliver the best image top quality.
With quite a few high definition video cameras on the
marketplace nowadays, the question of image quality all
depends on the camera and features, along with
your television or technique of play back. All high
definition video cameras are amazing in excellent
and playback, which is why they have grow to be so
favorite is such a smaller amount of time.
With Sony, JVC, and Canon continuing to develop
HDV, you know the technology will continue to get
much better and greater. When high definition 1st
hit the marketplace, it was an instant success. With
the integration of HDV, camcorders permit you to
do what you never could before.
In case you like to record precious memories, a high
definition video camera is just what you need. They
are extremely handy to have around, and you can find
various out there nowadays for you to choose
from - all you will need to do is pick the most effective 1
