With the growing popularity of the variable frame rate
VariCam HD Cinema cameras, HD production is on the
verge of changing HD video cameras as we know it. The
low cost 24p editing and finishing on the desktop, is
what Panasonic likes to call a VariDigm shift.
It all starts inside of the camera. The AJ-HDC27 from
Panasonic replicates several of the key features of
film based acquisition, which includes 24 frame
progressive scan images, time lapsed recording, and a
wide range of film rates for amazing camera effects.
The VariCam also comes with CineGamma software that
permits Panasonic’s HD Cinema camera systems to
match the latitude of film stocks and effects.
Even though it all starts inside of the camera, it
doesn’t stop there. HD has been showing up in many
more places besides HDTV. Panasonic is leading the
way with compact and affordable HD products. All
across the world, you’ll see Panasonic launching
HD products that are among the best and very affordable.
If your digital plans call for a transition to DTV
first then HDTV later on down the road, or if you plan
to take your station HD now, Panasonic has you
covered by making HD both flexible and affordable.
Whether your next commercial is a 30 second spot for
TV or a two minute commercial, shoot it on DVCPRO HD
without having to sacrifice quality. The 24P at 720
progressive resolution from Panasonic makes this
The coporate level presentations demand the highest
level of image quality. Professional presentations
begin with 720p and 1080i cameras from Panasonic.
By starting with the highest image quality available,
Panasonic ensures that you’ll have everything you
need to exceed your corporate needs and demands.

The Panasonic AG-HVX200 is a handheld HD p2 camera
recorder that’s designed to meet the emerging needs
needs in HD content production. The camera debuts
and remains Panasonic’s first HD video product to
use P2, the cutting edge memory recording device
that has the potential to revolutionize the entire
The AG-HVX200 can record HD, in either 1080i or
720p video acquired by a new optical system and
high performance digital signal processor onto a P2
card using the broadcasting DVCPRO HD codec. This
very system achieves a level of image quality that
conventional handheld HD cameras simply can’t match,
while also supporting HD/SD multi-format and multi
codec recording capabilities.
The visual frame rate recording is just one of the
many features that makes this camera so very unique
in its class. By using technology that makes the
Panasonic VariCam camera a favorite in movie
production, this powerful function will allow the
overcranking techniques used with film cameras
to create fast motion and slow motion effects.
The P2 card offers you superb reliability, immediate
playback, and amazing cost performance. It will
also allow direct connection to other editing
systems and streamlines the production work flow,
by providing to the editing system data files
ready to be edited, rather than a video tape
that would require the tedious task of digitizing.
On top of all the advanced features and technology,
the Panasonic AG-HVX200 inherits the refined
design and easy operation that seperates it from
the rest. With the AG-HVX200 HD camera,
professionals of all kinds will find a powerful
tool to help them create and bring their creations
to life – helping them achieve things they may
have never thought to be possible.

Crime is on the rise or so it seems. Whether you are operating your own business or just want to insure the safety of your own home, you may want to think long and hard about using hidden digital video recorders to keep an eye on things. If your business or home is fairly large, you know that you may need to have several hidden digital video recorders operating all at the same time. Fortunately, there are several models of hidden digital video recorders that can operate numerous security cameras all at the same time.
One unit in particular, allows you to connect up to eight cameras and has eight alarm inputs. The great part is that all eight cameras can be viewed on one monitor, so you don’t have to go broke building a wall of monitors to handle the job. Once an alarm goes off, the switcher will lock onto the camera covering the area where the alarm went off. And if more than one alarm sounds, it will switch automatically between the affected areas. You can also manually excluded unaffected cameras or lock the affected cameras so that you have a constant view of the trouble spot.
There is also a nine camera version of these hidden digital video recorders that allows you to change setting from one, two, four or eight camera viewing, too. The system adjusts to your needs regardless of how many hidden digital video recorders you are using. Then if you need to expand your system, you don’t have to worry about purchasing another system, you are ready to go for up to nine cameras.
All video cameras contain 3 major components – the
lens, imager, and recorder. The lens gathers and
focuses the light on the imager, which is normally
a charge coupled device (CCD) or CMOS sensor IC.
Finally, the recorder will encode the video signal
into a form that can be stored. Commonly, the optics
and imager are known as the camera section.
The optic lens is the first component in the camera
section’s light path. The optics normally have one
or more the following adjustments:
1. aperture – controls the amount of light
2. zoom – controls the field of view
3. shutter speed – captures continuous motion
In most consumer units, these adjustments are
automatically controlled by the video camera’s
electronics, normally to maintain constant exposure
onto the imager.
The imager is the “eye” of the camera, housing a
photo sensitive device or devices. The imager works
to convert light into an electronic video signal
through an elaborate electronic process. The
camera lens projects an image to the imager surface,
exposing the photo sensitive array to the light.
The light exposure is then converted into an electrical
charge. Towards the end of the timed exposure, the
imager will convert the accumulated charge into a
continuous analog voltage at the imager’s output
The third piece, the recorder, is responsible for
writing the video signal to a recording medium,
such as magnetic videotape. The recording function
involves many steps of signal processing, and
historically, the recording process introduced
some distortion and noise to the stored video,
such that the playback of stored signal may not
retain the same detail as the original live feed.
All but the most primitive of video cameras will
also need to have a recorder controlling section
which will allow you to control the camera. You
can also swich the recorder into playback mode
for reviewing your recorded footage.
The image you recorded doesn’t need to be limited
to what appeared in the view finder. For a
documentation of events such as those used by the
police, the fields of view will overlay such
things as the time and date of the recording along
the top and bottom of the image.
As you can probably tell now, a high definition
video camera is very complex indeed. There are
several other parts involved as well, although the
above are the most important. A HD video camera
is very complex in build, making it something
that is more than worth the time it takes to create.

If you’ve been looking for a high definition video
camera, there are many out there for you to choose
from. In this article, we will take a look at
some of your options available in each of the
JVC, Sony, and Canon all produce HDV cameras of
various stripes and abilities. The JVC HD100U
shoots 720p, offers a true 24p frame rate, and
provides a professional looking form factor, along
with sporting the ability to change out lenses.
The two popular HDV cameras from Sony include the
HDR-FX1 and the HVR-Z1U. Both of them shoot only
1080i and provide 24p. The XL h1 is Canon’s
entry to the HDV roundup. It provides HD SDI
output and gives you the option of interchanging
lenses. Like Sony, it shoots 1080i without true
All of these cameras are 3CCD models and all
sport level professional XLR audio inputs, with
the exception of the HDR-FX1. Sony also offers
single chip HDV cameras. The consumer HC1,
which is actually a miniature version of the FX1
is an excellent camera.
on the budget end of the Panasonic spectrum is the
AG-HVX200. This widely hyped camera does away with
tape based HD recording and will instead record
HD to either memory cards or even an attached hard
drive. It also offers the ability to shoot all
the above mentioned HD resolutions along with 50
Another popular camera for Panasonic is the Varicam
which shoots at 720p. A great feature with this
camera is the ability to shoot at variable frame
rates, which range from 4 – 60fps at 1fps intervals.
These different frame rates will allow you to
achieve a look similar to that of over cranking a
Sony couples their HDCAM cameras together under
the name CineAlta. They cover a broad range of
prices and features, ranging from the XDCAM HD
models and the F350 to the widely used and widely
The XDCAM HD cameras record directly to Sony’s
professional disc media, which is physically
similar to Blu-ray discs. These cameras can also
record various quality levels of 1080i and 1080p,
along with regular SD DVCAM. Unlike other HD
cameras from Sony, the XDCAM HD supports i-Link
for file access and DV output.
Near the high end of the Sony HD solutions is the
F900. It captures both 1080p and 1080i at
various frame rates, including 25p and 50i. This
is also the most expensive camera from Sony, as
it costs around 80,000$!

At first look, the JVC HD100 looks like any other
high definition camera with a lot of switches, dials,
and places to plug in peripherals. In operation, it
functions like an old regular video camera. You
don’t really need to do anything special to make a
high definition recording, just press a button -
although there are differences.
One of the things that makes this camera so nice and
unique is the amount of control you have over pretty
much everything you record. JVC really outdone
themselves here, as you can record all of your settings
on a SD memory card and save them to move on to
another JCV camera, which will save you a lot of time.
Another amazing feature enables the video camera to
automatically record to a hard disk while at the same
time recording to a tape. Recording directly to a
hard drive will save you a lot of time in the editing
process, as you can immediately begin using your
video without having to capture tape to your computer,
which can only be done in real time.
Surprisingly enough, the camera is very easy to use
either mounted on a tripod or on your shoulder. The
shoulder pad is a nice addition, being thickly padded.
To make things even better, the camera is very light.
When it comes to the quality, the GY-HD100 needs to
be seen to be believed. HD video is intended to look
like real life. There is an extended gray scale, a
heightened sense of color – and the resulting detail
is simply incredible.
HD at this incredible level has 720 X 1028 lines of
progressive video, which means that the video is shot
in one entire frame at a time. Also, it can be
recorded at 24 or even 30 frames per second.
The 24 fps resembles film and if you plan to convert
to film, it’s a great way to shoot – as you can
quickly and easily go directly to film. The 30 fps
has more data per second, although it is not
appropriate for making a film project.
If you want to experience HD without spending over
70,000$, then the JCV GY-HD100 is more than worth
your time and money. Even though it doesn’t record
uncompressed HD video, it does record a picture
that is far superior to the standard picture you get
with an average everyday camera. HD is rapidly
becoming the future, and with the GY-HD100 – its here

Sometimes, there are things going on behind the scenes of which you are not aware. This comes to be obvious when you are suddenly faced with something you never expected to happen. There are people in this world that only wish to make a quick buck at the expense of others. You may not even know the extent of it until it happens to you. A friend of mine learned this lesson when she decided to try selling JVC digital video cameras on eBay. She didn’t get scammed, but she almost did.
My friend found some JVC digital video cameras on an auction site other than eBay, and they were selling at a very cheap price. She decided to take a chance and get them, thinking she would make a good profit on eBay by reselling. When she received the JVC digital video cameras in the mail, she was pleased to see they were of good quality, and she did indeed get a good deal. She got three quality cameras, and was very excited about venturing into the world of eBay selling.
She listed her JVC digital video cameras and sat back and watched. She was worried that no one seemed to be biting, but I told her to be patient. There are a lot of cameras out there, and it may take some time for someone to see her auction. Even with her profit included, the JVC digital video cameras she listed were still a bargain. She sold one, and was over the moon. Before she knew it, an order was placed for yet another, but this order caused her some concern.
The ‘buyer’ suddenly had issues, and needed my friend to make some special considerations. She smelled a rat immediately. As it turned out, the buyer was trying to get her to mail the item to an overseas address. That in itself was not a problem, but the buyer was asking her for her bank account information so he could wire her the money. She knew better, thankfully, and she canceled the transaction and told the buyer they had to send her payment via money order or they item would not be shipped. She never heard from the buyer again, and she retained her JVC digital video cameras and avoided the scam. The folks at eBay confirmed her suspicions, and she counted herself among the lucky few. It happens all the time, so make sure you know what’s going on before you list high priced items on eBay.

You would be much better off if you spend equal amounts on the camera and the digital video camera zoom lens. The lens is that important. Your choice of lenses can distinguish between a good camera and an outstanding camera.
Spend More On The Lens
The digital video camera zoom lens determines how well your videos turn out. It, more than anything else on or in the camera affects the end products. Think about it, every shot you take goes through that lens. Really the camera is just a case for the mechanisms inside. You could make a case for reversing the spending, more on the lens and less on the actual camera. Most digital video cameras don’t come with the ability to change lenses. This fact makes it more important to purchase the best digital video camera zoom lens possible. Another piece of advice regarding the lens is too not purchase the plastic lenses. The clarity is much better from glass digital video camera zoom lens.
If you do plan on purchasing a video camera where you can change the digital video camera zoom lens then compare the options of each lens to find the one that you want. Experts recommend that you purchase brand names such as Canon, Pentax or Nikon. Be sure to check if the lens will work for your camera. Digital video camera zoom lenses are not created equal and a lens from Nikon may or may not work with a digital video camera made by Canon.
If you are a professional photographer, then you should check out Leica, Carl Zeiss and Leupold. These are specialty lens manufacturers. The quality of the videos will show if you use one of their digital video camera zoom lens. If you are just a beginner then these lenses may not be the best place to start, because of the cost. But if you want extraordinary quality, these digital video camera zoom lenses are the way to go.
Options for digital video camera zoom lenses include normal, wide angle and telephoto. The focal length of the lens has a lot to do with the type of digital video camera zoom lens choice. The quality of the lens is also determined by lens speed, a significant factor in your shoot quality. You should think about focusing distance as well as advanced features such as vibration reduction, USM or ultrasonic motor and filter thread which should be present in any good digital video camera zoom lens.
Before you make that digital video camera zoom lens purchase you should research each feature that you want and choose the lens that fulfils those wishes the best. As a rule of thumb, the more expensive lenses are usually the better choice since more of the elements in the lens with be glass, although this does increase the camera weight. In the end if you do the research and take into consideration your shooting needs and budget, you will make the right choice
A while 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 with a definition of 1080 lines and a
16:9 aspect ratio.
Shortly after that, Sony opened the door to high
definition by creating the first HDV camcorder, the
HDR-FX1. This release was on par with the launch
of the first DV camcorder in 1995, which at the
time was a giant step forward for image quality,
marking the break from traditional analog.
At the time, consumers were moving from the Hi8
format to DV, which featured much better image
quality, along with the ability to transfer to a
computer without any degradation of signal. With
HDV, the resolution of camcorders can be doubled,
from 576 lines to 1080. The compression method 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, which 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 in the USA and Japan.
The progressive mode format requires a television
set that supports it, while interlaced mode is
the natural scan mode that televisions use. The
question today is which of the two formats
deliver the best image quality.
With several high definition video cameras on the
market today, the question of image quality all
depends on the camera and features, along with
your television or method of play back. All high
definition video cameras are amazing in quality
and playback, which is why they have become so
popular is such a small amount of time.
With Sony, JVC, and Canon continuing to develop
HDV, you know the technology will continue to get
better and better. When high definition first
hit the market, it was an instant success. With
the integration of HDV, camcorders allow you to
do what you never could before.
If you like to record precious memories, a high
definition video camera is just what you need. They
are very handy to have around, and there are
several out there these days for you to choose
from – all you need to do is pick the best one
