The Digital Video Universe
Profit outlooks and shrinking demand in the technology industry not-withstanding,
the digital video revolution is well underway. There are still home videos to be
edited, videos to be distributed, and full length movies to be produced. In previous
generations, video editing and recording was accomplished through analog means
by video professionals who had access to high-priced machinery and video
equipment. Thus, many of those who wished to edit home footage or videos, if they
were lucky enough to have it recorded in the first place, never had the chance to
display their creative prowess when it came to video editing unless it involved
enrolling in film schools and obtaining access to production studios.
When the computer descended upon our lives and immersed itself in our world, it
was only a matter of time until processing speeds were incredibly fast and disk
space was vast enough to begin editing video at home with software applications
that didn’t require expensive video specialists, equipment or any other gadgets.
And coinciding with the computer industry’s major influence was the birth of the
DV (digital video) format, an international standard intended for consumer use,
back in 1995.
The DV Format: A Brief History
Like a seamless emergence and natural coalescence with desktop video editing, the
advent and proliferation of DV camcorders were sure to spark continued interest in
the infinite possibilities of digital video. What began back in 1995 and a DV format
agreement reached by a consortium of companies that included Hitachi, Ltd., Sony
Corp, Sharp Corporation, Thompson Multimedia, Mitsubishi Electric Corporation,
Victor Corporation of Japan (JVC), Matsushita Electric Industrial Corp. (Panasonic),
Philips Electronics, Sanyo Electric Co. Ltd., and Toshiba Corporation, is still being
ironed out until this day in terms of a consensual format.
The frontrunners at the time and still are until this day, are Sony and Matsushita
(Panasonic), which beat out the competition with their consumer releases hitting the
market first. Soon after though, the format wars began with professional DV
variants such as DVCAM (Sony) and DVCPRO (JVC) despite the DV format
agreement. Luckily, the basic DV format is still intact, but other factors were altered
(i.e. tape type, track pitch and width) so we are still left with backward-compatible
formats or incompatible formats between models from differing companies.
Hopefully, this won’t impact or trickle down to the consumer segment anytime soon.
What exactly is the DV format then? To start with, it has a 5:1 compression ratio and
its compression technology is quite similar to MPEG (e.g. DVD Video format).
Tips: For more information on MPEG, refer to "What Is MPEG?" on page 109.
