Understanding Consumer Video EquipmentWhen I was a kid,my dad shot home movies using a Super 8 film camera. Themovies themselves were about what you would expect—lots of cute little kids muggingabout in a dark, shaky, poorly focused little film.Well, all that’s changed. Thanks to today’s digital video technology, you can nowshoot videos in high resolution and edit them on your home computer. The resultsare often indistinguishable from what you’d get from a professional video productionhouse, complete with sophisticated editing and special effects. And the costsare no more, in today’s terms, than what my dad spent back when I was a youth.It’s amazing: Digital video recording lets you use your PC as a movie-editing studioto create sophisticated videos for YouTube distribution.How Camcorders WorkThe key to successful semi-pro video production is to start with a digital camcorder.Fortunately, now that older analog VHS camcorders have been relegated tothe garbage bin or to Craigslist classified ads, virtually every camcorder sold todayrecords in a digital format.The nice thing about today’s digital camcorders is that they’re easy enough for evenan executive to use, and they produce high quality results. Just point the camcorder,press the Record button, and zoom into the shot. Some higher-end camcorders featureimage stabilization technology, so shaky pictures are a thing of the past. And,with today’s digital recording formats, the movies you shoot are at professionalquality levels.Let’s start with the basics.As you can tell from its name, a camcorder is actually twodevices in one, combining a video camera and video recorder into a single unit. Thecamera part of the unit senses the image, and the recorder section records it.In the camera part of the camcorder, the process starts when the image is seenthrough the camera’s lens. The higher quality the lens, the more light passesthrough it without distortion of the image.The image as seen by the lens is beamed onto a charge-coupled device (CCD),which is an electronic chip that captures the light falling on it and converts the lightto electrical signals.Most consumer-level camcorders use a single CCD to capturethe video image. Some high-end camcorders, however, use three CCDs, one foreach of the primary colors (red, green, and blue), which provides better detail andcolor.Most professional video cameras use a three-CCD design.90 Par t I I Producing Your YouTube Videos
