With a number of high-definition digital camcorders now on the market, its time to get up to speed on what to look for. Here, youll find a selection of whats being offered, plus tips on how to get the best out of your purchase. High definition isnt just limited to HDTV, Blu-ray or HD DVD. Manufacturers are now designing camcorders aimed at consumers that will digitally capture video in HD resolution. Its not just for the pros anymore. High definition refers to any video system of higher resolution than standard definition (SD). This is usually measured in the number of horizontal lines in the image. HD on camcorders today is either 720p (720 lines of resolution) or 1080i (1080 lines of resolution). Each format delivers a pleasing 16:9 widescreen aspect ratio. Theres much nit-picking over which format is better. As you may have noticed, 1080 has an i attached to it, meaning the image captured is interlaced. Basically, each frame that you see in this format is split into two half-frames of 540 lines that flash an instant before the next 540 lines are seen. This is all done so quickly (usually at 1⁄60 of a second for each half-frame) that the human eye doesnt notice the two fields. The p in 720p refers to progressive frames. This is the exact opposite scenario, where every frame contains all the information at once. In essence, both formats deliver crisp, sharp detail, and youll be hard pressed to see any difference between the two. |
