This compares to previous technology where they would be separate. HistoryVideo cameras were originally designed for broadcasting television images — see television camera. Cameras found in television broadcast centres were extremely large, mounted on special trolleys, and wired to remote recorders located in separate rooms. As technology advanced, miniaturization eventually enabled the construction of portable video-cameras and portable video-recorders. Prior to the introduction of the camcorder, portable video-recording required two separate devices: a video-camera and a VCR. Specialized models of both the camera and VCR were used for mobile work. The portable VCR consisted of the cassette player/recorder unit, and a television tuner unit. The cassette unit could be detached and carried with the user for video recording. While the camera itself could be quite compact, the fact that a separate VCR had to be carried generally made on-location shooting a two-person job. In 1982, Sony released the first professional camcorder named "BETACAM". BETACAM was developed as a standard for professional camcorders. At first, cameramen didn't welcome BETACAM, because before BETACAM, carrying and operating the VCR unit was a work of a video engineer, after BETACAM, they came to be required to operate both video camera and VCR. However, the cable between cameramen and video engineers was eliminated. For this reason, the freedom of cameramen has improved dramatically and BETACAM became standard. In 1983, Sony released Betamovie for consumers, the first domestic camcorder. A novel technique was used to reduce the size of the spinning video head drum, which was then used for many subsequent camcorders. The unit was bulky by today's standards, and since it could not be held in one hand, was typically used on resting on a shoulder. Some later camcorders were even larger, because the Betamovie models had only optical viewfinders and no playback or rewind capability. Most camcorders were and still are designed for right-handed operation, though a few possessed ambidextrous ergonomics. Within a few years, manufacturers introduced two new tape formats tailored to the application of portable-video: the VHS-C format and the competing 8mm. VHS-C was essentially VHS with a reduced-size cassette. The VHS-C cassette held enough tape to record 30 minutes of VHS video, while a mechanical adapter enabled playback of VHS-C videocassettes in standard (full-size) VHS VCRs. VHS-C allowed manufacturers to reduce the weight and size of VHS-derived camcorders, although at the expense of recording time. The alternative 8 mm video on the other hand radically reduced the size of camcorders without the problem of short running time, by using an all-new metal composition video cassette. 8 mm video used a tape whose width is 33% less than VHS/Betamax tape (~12.7 mm), allowing even further miniaturization in the recorder's tape-transport assembly and cassette media. • [List your site here Free!]
