Brief Camcorder History

Video cameras were originally designed for broadcasting television images. Cameras found in television broadcast centers 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 were introduced by both JVC (VHS) and Sony (Umatic & Betamax) to be used for mobile work. The portable VCR consisted of the cassette player/recorder unit, and a televisiontuner 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-man job, however the advent of these portable VCRs helped to eliminate the phrase "film at eleven". Rather than wait for the lengthy process of film developing, portable VCRs and video cameras allowed video to be shown during the 6 o'clock news.

In 1982, two events happened that eventually led to the home camcorder boom: JVC introduced the VHS-A format, and Sony released the first professional camcorder named Betacam. VHS-C was essentially VHS with a reduced-size cassette that had been designed for portable VCRs. Sony's Betacam was a standard developed for professional camcorders, which used component video to provide a superior picture. At first, cameramen did not welcome Betacam, because before it, carrying and operating the VCR unit was the 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, the freedom of cameramen improved dramatically and Betacam quickly became the standard for both news-gathering and in-studio video editing.

In 1983, Sony released the Betamax-based Betamovie BMC-100P, the first consumer camcorder. A novel technique in the BMC-100P was used to reduce the size of the spinning video head drum, which was then used for many subsequent camcorders. Nevertheless, the unit could not be held with one hand and was typically 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. That same year JVC released its own camcorder using its pre-existing VHS-C format. The VHS-C cassette held enough tape to record 40 or 120 minutes of VHS video, while a mechanical adapter enabled playback of VHS-C videocassettes in home VCRs.

In the meantime, Sony was busy redesigning its Betamax system to create the new Video8 standard, released in 1985. Video8 eliminated the problem of short running time, by using an all-new metal composition video cassette whose 8mm tape 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.

Both VHS-C and 8mm video represented a trade-off for the consumer. Although the Video8 and Hi8 camcorders produced quality equal to VHS-C and Super VHS-C camcorders (250/420 lines horizontal), the standard 8 mm cassette had the advantage with up to two hours length (four hours in slow mode). On the down side, since the 8 mm format was incompatible with VHS, 8 mm recordings could not be played in consumers' VHS VCRs. Equally important entry-level VHS-C camcorders were priced less than 8 mm units, and thus neither "won" the war. It became a stalemate. (Side note - In 1985, Panasonic, RCA, and Hitachi began releasing full-sized VHS camcorders, which offered up to 2 hours of record time, and thus found a niche with videophiles, industrial videographers, and college TV studios.) S-VHS full-sized camcorders were later released in 1987.

In the mid-1990s, the camcorder reached the digital era with the introduction of DV and MiniDV. Its cassette media was even smaller than 8 mm media, allowing another size reduction of the tape transport assembly. The digital nature of miniDV also improved audio and video quality over the best of the analog consumer camcorders (SVHS-C, Hi8), although some users still prefer the analog nature of Hi8 and Super VHS-C, since neither of these produce the "background blur" or "mosquito noise" of Digital compression. Variations on the DV camcorder include the Digital8 camcorder and the MPEG2-based DVD camcorder.

The evolution of the camcorder has seen the growth of the camcorder market as price reductions and size reductions make the technology more accessible to a wider audience. When camcorders were first introduced, they were bulky shoulder-operated luggables that cost over $1,500 US dollars. As of 2008^[update], an entry-level camcorder fits in the palm of a person's hand and is sold at a retail price of approximately 100 US dollars.
