A digital video recorder is a combination of a video camera and a recorder that relies on digital technology for image and sound capturing. Call it a camcorder and people will know what you refer at. One technical peculiarity that makes a digital video camcorder is the data storage device; a flash drive, a memory card or a built-in hard disk drive can be equally used here. Some types of equipments allow for the use of all these three media types hence the name of hybrid camcorders.
A modern digital video camcorder captures the image by focusing the light on the imager (sensor), and incidental light then gets transformed into an electrical signal. The digital video results from this electrical signal that becomes storable. A digital video carmcoder can be analyzed by each of its components. As for optical control, many devices include manual and automatic operational modes, so as to suit the user’s requirements.
The light exposure is regulated from the aperture or iris, while the angle view and the focal length are controlled by the zoom. The neutral density filter is one other feature available with a digital video camcorder. The functions are automatic, but many professionals choose to operate the optical functions manually.
The sensor or imager in the structure of modern digital video camcorder models is considered superior to the other methods of image capturing by the possibility of displaying colors better. Although the light capability is lower, the images will be clearer. Yet, the storage capacity of the digital camcorder should not be overlooked either. There is no fading, color change or color bleeding in the use of the digital devices, which makes the digital video camcorder superior to any analog device.
As for technical performance, statistics indicate that the Betacam so far offers the best digital formats for the editing of materials. Moreover, with digital connections, there are no bandwidth problems or the noise that usually affect analog recordings. If the storage unit is intact, digital storage has not limitations in terms of time. Yet, should a technical problem occur, the loss of archives is usually complete with any camcorder digital video.
