Hd Camcorders
from AllProduct description
A camcorder (video camera recorder) is an electronic device that combines a video camera and a video recorder into one unit. Equipment manufacturers do not seem to have strict guidelines for the term usage. Marketing materials may present a video recording device as a camcorder, but the delivery package would identify content as video camera recorder.
In order to differentiate a camcorder from other devices that are capable of recording video, like cell phones and compact digital cameras, a camcorder is generally identified as a portable device having video capture and recording as its primary function.
The earliest camcorders employed analog recording onto videotape. Since the 1990s digital recording has become the norm, but tape remained the primary recording media. Starting from early 2000s tape as storage media is being gradually replaced with tapeless solutions like optical disks, hard disk drives and flash memory.
All tape-based camcorders use removable media in form of video cassettes. Camcorders that do not use magnetic tape are often called tapeless camcorders and may use optical discs (removable), solid-state flash memory (removable or built-in) or a hard disk drive (removable or built-in).
Camcorders that permit using more than one type of media, like built-in hard disk drive and memory card, are often called hybrid camcorders.
Other devices with video-capture capability
Video-capture capability is not confined to camcorders. Cellphones, digital single lens reflex and compact digicams, laptops, and personal media players frequently offer some form of video-capture capability.
In general, these multipurpose-devices offer less functionality for video-capture, than a traditional camcorder. The absence of manual adjustments, external-audio input, and even basic usability functions (such as autofocus and lens-zoom) are common limitations.
More importantly, few can capture to standard TV-video formats (480p60, 720p60, 1080i30), and instead record in either non-TV resolutions (320x240, 640x480, etc.) or slower frame-rates (15fps, 30fps.)
When used in the role of a camcorder, a multipurpose-device tends to offer inferior handling and audio/video performance, which limits its usability for extended and/or adverse shooting situations.
However, much as camera-equipped cellphones are now ubiquitous, video-equipped electronic devices will likely become commonplace, replacing the market for low-end camcorders.
The past few years have seen the introduction of a slew of DSLR cameras with high-definition video. Although the current crop still suffer from the typical handling and usability deficiencies of other multipurpose-devices, DSLR video offers two videographic features unavailable on consumer camcorders, shallow depth-of-field and interchangeable lenses.
Professional video-cameras possessing these capabilities are currently more expensive than even the most expensive video-capable DSLR.
In video applications where the DSLR's operational deficiencies can be mitigated by meticulous planning of the each shooting location, a growing number of video productions are employing DSLRs, such as the Canon 5D Mark II, to fulfill the desire for depth-of-field and optical-perspective control.
Whether in a studio or on-location setup, the scene's environmental factors and camera placement are known beforehand, allowing the directory of photography to determine the proper camera/lens setup and apply any necessary environmental adjustments, such as lighting.
A recent development to combine the feature-sets of full-feature still-camera and camcorder in a single unit, is the combo-camera.
The Sanyo Xacti HD1 was the first such combo unit, combining the features of a 5.1 megapixel still-camera with a 720p video recorder. Overall, the product was a step forward in terms of a single-device's combined level of handling and usability .
The combo camera's concept has caught on with competing manufacturers; Canon and Sony have introduced camcorders with still-photo performance approaching a traditional digicam, while Panasonic has introduced a DSLR-body with video features approaching a traditional camcorder.
