Digital Video Camera - For Those Who Are Going To Buy Their First!
A digital video camera is a modern motion picture camera which records videos in the digital format to store video, unlike the older models, which stored video data in the analog format. A digital video camera has the ability to store the video data on a tape, on an optical disc such as a DVD, or on a hard drive fitted in the body of the camera.
A digital video camera can capture an image in both progressive-scan and interlaced-capture modes.
A digital video cameras that uses the interlaced-capture mode stores images as alternate lines, beginning first with odd-numbered lines and subsequently moving on to capture even-numbered ones. Once both the sets of lines are captured a frame id is formed. The digital video camera then starts this process all over again.
In a digital video camera that uses the progressive-scan mode every frame is recorded as a distinct entity, unlike interlacing, in which the digital video camera uses the process of scanning in a continuous manner. This provides the progressive-scan capable digital video camera a capability to output better quality images, as compared to its interlaced cousin. Most digital video cameras use the standard DV format to record the video. They are compliant with the IEC 61834 specification, which has defined the codec to be used for video compression as well as the tape, which shall be used by the digital video camera. For connection to non-linear video editing suites, the digital video camera uses the IEEE 1394 Firewire connector, which provides high bandwidth to stream video from the camera to the editing platform,, because digital video is large in size and the use of connections based on slower standards would make the process of the transfer of video from the digital video camera to the editing platform a very sluggish process. The modern digital video camera is very compact in size, yet it comes with optical zoom as high as 30X. This makes it possible for the user to get closeups and shots of objects that are far away. Some digital video cameras claim to have high levels of digital zoom. You must consider that digital zoom means that the quality of image will go down substantially. Therefore, it is useless in a digital video camera to have very high levels of digital zoom, even if the company claims to offer digital zoom levels as high as 200X. The large zoom ability also means that the result of camera shake gets multiplied. This makes it necessary to ensure that such shakes be compromised. The digital video camera comes with on-board digital image stabilization features, which compensate for minor camera shakes. However, it must be kept in mind that just like digital zoom, digital image stabilization is also just a gimmick when compared to the optical image stabilization features offered by the digital video camera. These optical image stabilization features really have a significant effect on the quality of the image output by the digital video camera. Today, the excellent features and advantages of digital video cameras have virtually made conventional cameras obsolete. Even professional photographers and amateur photo enthusiasts now use a digital video camera to take photographs as the usage cost of this camera is not only much lower than that for a conventional camera, but their digital images can also be easily edited on PCs through the use of photo editing software.
