A video camera is a camera used for electronic motion picture acquisition, initially developed by the television industry but now common in other applications as well. The earliest video cameras were those of John Logie Baird, based on the electromechanical Nipkow disk and used by the BBC in experimental broadcasts through the 1930s. All-electronic designs based on the cathode ray tube, such as Vladimir Zworykin’s Iconoscope and Philo T. Farnsworth’s Image dissector, supplanted the Baird system by the 1940s and remained in wide use until the 1980s, when cameras based on solid-state image sensors such as CCDs (and later CMOS active pixel sensors) eliminated common problems with tube technologies such as image burn-in and made digital video workflow practical.
Video cameras are used primarily in two modes. The first, characteristic of much early broadcasting, is live television, where the camera feeds real time images directly to a screen for immediate observation. A few cameras still…

Online Video has become an outlet for the automotive enthusiast to create a memory of a track day and to do a little showing off to online enthusiasts on forums, blogs and YouTube.

When riots broke out in Vancouver after—of all things—a loss in a hockey game, the online video world exploded with eyewitness video shot on camcorders and mobile devices. And the same thing happened with the riots this week in the UK. In both cases, those eyewitness videos, many of which have gone viral, have helped ...

Shaquille O'Neal is one of the most accomplished and beloved professional basketball stars in the world. He's one of the few players who has won championships playing for multiple different teams.

I wrote yesterday about the discovery problem with online video.

For little more than a year now, I have been making video marketing productions using two Canon DSLRs as my weapon of choice: a 5D mark II (for its ability to do bokeh-porn) and the 7D (for those smooth Glidecam shots at 50 or 60 frames per second). Although both Panasonic (AF100) and Sony (F3) ...
