Camcorder buying guide, key camcorder you need to know

Digital video and FireWire
There are two main types of cameras Video: analog and digital. Analog camcorders record image information on the tape as a series of waves and electronic pulses. Digital camcorders translate the video signal into a computer, and then store it on tape. Analog video camera is like a typewriter, while a video camera is like a digital computer. The advantages of a digital video camera is that the quality is higher, and no quality is lost the tape to make a digital copy. Writing is also much easier with a video camera is a digital analog video camera. Digital camcorders used to cost more $ 2,000, but many models are available from $ 300. The manufacturers are stopping production of film cameras altogether.

Like most All consumer camcorders now record digital video service, it is necessary that the camcorder is capable of transferring digital data to good href = "http://www.global-battery.co.uk/laptop-batteries/dell-vostro-a860.htm"> Dell Vostro A860 battery from the computer or other digital recording equipment. This is done via FireWire, another name for IEEE 1394 series of high performance. The Most consumer camcorders have FireWire camcorders is sent to a computer to transfer data. Because FireWire can carry more data at high speeds a USB cable can be, it is good to use while in video editing programs. FireWire is standard on today's cameras. It is important, however, to verify that your computer has a FireWire connection.

CCD pixel size and
CCD is for charge-couple-device, and is often referred to as a chip. The chip converts visible light into an electronic signal, which the camcorder reads and stores on tape. Generally speaking, video cameras broadcast more, better CCD, often have 1/2-inch to 2/3-inch CCD, while consumer camcorders usually have them in 1/6-inch to 1/3-inch window. In the CCD, the more light the image is taken, resulting in brighter images with better colors. CCD size is very important in low light. size CCD camcorders use vary according to each model and manufacturer, and should always be taken into account. The difference between a 1/6-in. and 1/4-in. CCD may seem low, but when these values are squared to measure the surface, has a significant effect of quality video and low light.

The key distinction is the difference between them three CCDs. always have three CCD miniDV, one for each primary color. Until 2002, consumer camcorders usually only had one. The colors of professional video cameras with three CCDs are much more clear and bright, realistic colors and precise than camcorders with one CCD. A three-CCD camcorder camera almost always better than a CCD and the quality difference in both normal and low light shooting is noticeable. Best part is that camcorders three CCDs are beginning to make inroads in the market consumption. Given that three-CCD technology has already failed is less than $ 2,000, now there are three CCD cameras available for less than $ 1,000, and prices are falling every day.

Another thing to consider is the number of pixels on the CCD. The more pixels the CCD, the image, but it is a bit misleading. A standard video image is only 340 000 pixels in it. Increase pixels have little effect on the sharpness of the image after exceeding 340,000. Of course, the video could never be as simple as that, and usually, you will see sharper images, even between 1 and 2 megapixel megapixel CCD. However, this effect is subject to diminishing returns. It is also noted that there are two measures of the CCD pixels: Gross, which is the total number of pixels in the CCD, and effective as actually used in the CCD. The number of effective pixels is important.

Zoom lens
Zoom can be classified as optical and digital and virtually all camcorders have both. normal range optical zoom 2x to 20x increase, while a digital zoom range from 20x to 800x. Although the use of optical zoom physical movement of the mechanism of lens, digital zoom is simply the expansion of digital pixels. Lead Digital Zoom image confusion call pixellation. Using a digital zoom significantly reduces the video quality, and we recommend always turn off the digital zoom. We also recommend that consumers ignore the any digital zoom video camera, because it is more marketing hype and not a quality characteristic. The manufacturers have scandalously 500x zoom 800x digital or large that may seem impressive on paper. If you were to actually use these approaches, however, the video would be impossible to see.

Media: Tape, Flash or DVD
Currently, there are three main types of media video camera, cassettes, DVDs, and flash. (There are two analog and Digital, but we at Camcorderinfo.com focus on digital.) Today, most MiniDV camcorders record digital video. A second band in digital format Digital8, was invented by Sony.

It is important to note that digital images are not recorded on the tape, but news flash, like cameras digital. The different types of flash media are used by different manufacturers, including SD, Compact Flash and Memory Stick and Memory Stick Duo. A very small number of cameras no tape or DVD mechanism and can record video to a flash media card. These flash media camcorders are just starting out and have not taken into reality.

DVD Recorder video cameras have become very popular in recent years. DVD camcorders record video in DVD recording of smaller size. DVD-registration can cause confusion, but because they are different flavors of DVD, each with its own advantages.

There are three formats of DVD video cameras using DVD-R, DVD-RW and DVD-RAM. These formats are very similar to CD fuel. DVD-R can not be erased once registered. One of the advantages of a DVD camcorder is that you allow editing in the chamber. You can delete scenes, move, and even cut some models. This is only possible with a DVD-RW and DVD-RAM. The disadvantage of the two formats is that all players DVD can read DVD-RW or DVD-RAM discs. Moreover, most DVD players (with the exception of some of the first) can play DVD-R.

Image stabilization
Image stabilization is an important factor in performance, especially if you are not using a tripod. Stabilization imaging eliminates some of the weaknesses that occur when you give a camcorder. There are two types of image stabilization: optical and electronic. stabilization Electronic Image camcorder internal computer uses the electronic image moves in the opposite direction moving the least agitation. What makes the image zoom small, which gives the camcorder a little "wiggle" room. The optical image stabilization follows the same concept, but the camera is moving parts actually the lens to compensate the tremor. The downside of electronic image stabilization is that sometimes the image quality deteriorates. Stabilization optical image stabilization is better than electronics, like the optical zoom is better than digital zoom. Unfortunately, most camcorders stabilization consumer electronic image.

Audio
Somehow, the audio recording with the camcorder is equally vital that video. However, this should not be a mark of progress or failure in the area of your camcorder purchase decision. Most camcorders generally equal in their microphones to record audio attached – just as bad, that. Often there are problems with the engine noise bands, the operational noise problems with the video camera hands … Sometimes the camera to record just right. When you look at the audio portion of the camcorder purchase search options. We recommend using an external microphone instead of one that comes with the camcorder, so you need to find a microphone jack. It is also good to have a headphone jack so you can monitor your potential problems and correct audio during recording. In addition, over some final consumer camcorders, and some intermediate level include manual audio control, that allows the user to adjust the audio level of the microphone channel, which is important when something like the recording of a concert, or something very soft or loud.

Imagery fixed
Still image quality is measured in pixels, usually presented as a number of megapixels. For many years, manufacturers cameras Video has been the integration of imaging characteristics in video cameras. However, as stated above, your best shot is to buy a separate chamber FUJIFILM NP-40 camera. If the value placed on still images (which many consumers do), to find a number of megapixels, a flash on the camera and the included memory card capacity.

Auto Exposure Modes
Many consumer cameras including preset shutter speed and exposure that has a performance window shutter speed and exposure. These usually include sports presets low light, sun and ski, landscape, close, etc. If you are not familiar with the manual, these modes can be very useful.

Widescreen
This term characterizes the aspect ratio of 16:9, and comes in a conversation often 16:9 mode. An aspect ratio is a way to describe the relationship between the duration of a picture of how is everything. In the video, the standard aspect ratio is 4:3, which is 4 inches long, 3 cm high. In the film, the standard aspect ratio is 16:9. That's why sometimes you will see black bars top and bottom of the screen of a film that became to television. This is because the real movie is too large to display on the screen. While television you have at home is likely designed for a proportion 4:3, many people want this panoramic look at the film. (Some even have a TV aspect ratio of 16:9.) For this reason, many camcorders include a wide-screen mode. Some inexpensive cameras that can produce images that are actually in 16:9 but most consumer camcorders because of the size 4:03 its CCD (see above) have to approximate the 16:9 format with a series of tricks developed by the manufacturers.

LCD displays
LCDs and viewfinders are the mechanisms used to read the camcorder itself. Although almost all consumer camcorders can be connected to a TV for playback, the screen LCD and viewfinder offers instant playback of media. In general, the more pixels on the LCD screen or viewfinder is better, pixels are expressed in thousands, and 123K (123,000 pixels). Sized LCD display is measured diagonally. An LCD screen of 2.5 inches with 2.5-inch sides.

Focus
An image is sharp when it is crisp and clear for the viewer. In another, a focused image occupies the focal point of an objective mechanism. The focal point of a lens system is extent that all refraction or reflection of light rays converge on the target, the focal distance of the lens focal point. camcorder options autofocus and general manual. In terms of options ranging from manual focus ring is the best approach, but most consumer camcorders have is cheaper or focus Jog Dial manual button.

Shutter speed
The shutter speed refers to the speed of opening, or rotation, the camera shutter video. (Figure Go). Each time the shutter opens, a certain amount of light is admitted to the CCD. Shutter speeds are measured in revolutions per second: 1 / 60, 1 / 2000 shutter speeds, etc, as 1 / 2000 to admit less light, because the opening of a given period of time is low. Slow or low shutter speed allow more light to stay open longer. A low shutter speed record in the fast can cause confusion or leakage effect, rapid shutter can capture moving objects, such as athletes, dryly. Decreased intake high shutter speed of light can be compensated by the increased exposure / Aperture.

Exhibition and Opening
Exposure refers to the printer exposure to light. While the shutter speed regulates the range exposure, iris – more specifically, the aperture – controls the amount of light that allows a given time. More from the iris, the largest opening, the greater is the f-stop (the measure of exposure), and more light is left on the target, resulting in a sharper image.

Gain
Gain is concerns the level or intensity of the video signal. In some consumer video cameras can be increased by increasing the signal amplitude or gain. This allows better performance in low light, the image becomes generally brighter, but often at the expense of clarity, that the noise also increases. The gain is measured in decibels. (0 dB, 6 dB, 18 dB, etc.)

Webcam
Progressive Scan
Some consumer camcorders, especially the larger ones, offer scanning options to capture progressive video. There are two types of scanning: progressive and interlaced. The video is captured in the areas of resolution. Also taken at a rate of some symptoms (30 frames per second, etc.) With interlaced scanning, two fields of data stored in each table. Each field consists of alternating lines of resolution. Once two fields of alternating lines of resolution are included, a frame is said to be created, composed of two executives of the resolution of deadlock. The fields of the resulting image recorded in an alternating sequence. Therefore, when read, can not stop and display a single image and see a clear image. Instead, seeing interlaced frames recorded, you see a flicker between the fields, like the light in the VCR is broken VHS tape. Typically, consumer camcorders record in 60i, which means 60 frames per second interlaced. It is actually 60 frames per second, which is locked when the creation of 30 frames per second.

In progressive scanning, the two areas of resolution composing each image are caught together in the same time, similar to film a series of still images are recorded in order. Although a minute of video recorded at 30p (30 progressive scan pictures) contain about the same amount of data as a minute of video recorded at 60i, there are slight differences. In general, the scanning rate produce a progressive movement that is more like the film is formed, while interlaced scanning produces a slightly less smooth movement. Both scan rates progressive 30p and 24p are available in video cameras. While 30p is available in some real high-end camcorders, it is often approached by modifying an exploration 60i. It is even more true 24p, so unhappy.

Many independent filmmakers and video nuts rubbing his hands on the camcorders recording capacity in 24p. Although this option is almost always the result of any treatment effect, taking the result is said to approximate the look of film. In fact, Many fans want to 24p because of the possibility that the final video to film transfer. Today, you can not find real 30p camcorder under $ 3,000.
