Camcorders Mainly Based On Digital Technology

Monday, June 27th, 2011

Camcorders are consumer electronic devices that have as their primary function the capture of both images and sound. The term is an abbreviation for video camera recorder. These units combine a video recorder and a video camera into one unit, usually handheld.

The term can cause confusion. Many electronic devices like cell phones, Apple iPad 2 and digital compact cameras have some limited capability to record both sound and moving images. The iPad also allows some video editing applications. Camcorders were originally designed to capture images for broadcast via television, particularly news teams.

Not all video devices provide lens zoom, manual adjustments, autofocus or external-audio input. Few if any can capture to high quality, standard TV-video resolutions (like 480p60, 720p60 or 1080i30). Instead they produce output in lower quality record in either non-TV resolutions (like 320×240 or 640×480 and so on). They also usually provide slow frame-rates (like 30 frames per second or even slower at 15fps).

The first digital format unit, known as D1, was released a few years later in 1986 by Sony. Images were recorded and stored in uncompressed form and needed a very large amount of memory storage space. Data compression for video was introduced in 1992.

Digital units divide into tape-based or tapeless. Tape-based models are now rare having been replaced by digital storage media such as SD cards, flash memory or their own dedicated internal hard disk drive. Virtually all consumer models are sold with basic video editing software. Users can use this software to edit their content and create DVDs.

In 1995 a group of camcorder manufacturers collectively launched the DV codec as a standard format for home videos and independent filmmaking. In 2000, Panasonic expanded the DV codec by launching its DVCPRO HD. This format was targeted at the professional market for the production of high definition videos. It used DVCPRO full-sized cassettes and was expensive.

In 2003, Sony, JVC, Canon and Sharp improved on the DVCPRO HD system when they launched HDV. This system was the first affordable high definition video format based on inexpensive MiniDV tape cassettes.

There is an incredibly large choice of camcorders to meet the needs of both hobbyist consumers and dedicated professionals. They now form part of the regular equipment used by families and tourists as well as media professional. Review services like Kelkoo can assist users more quickly find the model that best meets their needs.

A Few Ideas For Purchasing Camcorders Online

Camcorders are easily found on the web. Finding a site that will give you the information you need may take some time. Know what features are important to you and choose a site that you are comfortable using. Here are some things that make a site useful and some features that may be important to you.

The more options you are given under which to search, the more precise you can be in looking for your next video recorder. Most sites will offer a search by price and brand. Look for sites that give you the option to choose different technologies that are important to you. More options mean you get more information and better choice.

How the recorder will be used will dictate the need for clear and detailed pictures. Many people just want to document an event and are not interested in the detail. Others use videos for the information that they can capture both basic and specific. Resolution is about megapixels. The more detail the camera can pick up the better for manipulating the data.

Subjective consumer and objective industry reviews are helpful in understanding the products. Industry reviews give you in depth and technical information void of emotion and opinion. The consumer information gives you real life trials and tribulations and can uncover some idiosyncrasies that the objective reviews can miss.

In order to understand what you are looking for and comparing, you will have to invest some time into the terminology of the technology. Recording comes in five different formats. HDD or hard disk drive saves info to an internal drive. Video choices can be in standard (SD) or high definition (HD). The more disc storage the higher the price. Flash memory also stores information directly in the camcorder but with less capacity.

Memory cards are inserted into the camera and you can choose the size of memory. This type is common in the smaller recorders. Look for SD (secure digital) or SDHC (secure digital high capacity) compatible.

Recording to DVD or a mini-DV (digital video) tape allow for less cost for the product but will require that additional storage will have to be available. Additionally these formats require a bigger chassis to accept the storage device.

Zoom comes in digital or optical. If details are important choose the optical feature. If your choice is a heavy camera, make sure it has a motion stabilizer. The smaller the product is the smaller the microphone. If sound is important, make sure you can plug in a external mic. Viewfinders will be a flip out screen or an eye viewer. Search for a web site that will allow you to compare camcorders based on their features.
