High definition (HD) camcorders are a natural fit for the growing number of HDTVs in living rooms across the country. Prices on HD camcorders continue to drop, while more and more camcorder manufacturers are expanding the number of HD models they carry.
There are three main resolutions of HD video available: 1080p, 1080i, and 720p. Most HD camcorders on the market record in either 720p or 1080i resolution.
Interlaced Video: Typical standard definition video is interlaced video, as is 1080i. In interlaced video, your camcorder will record every other line of resolution. It would start by showing lines one, three and five and then follow later with lines two, four, and six.
Progressive Scan Video: Progressive scan video records each line of video in order without skipping any lines. So it would start first with line one and work its way all the way to line 1080. Progressive scan video typically looks better than its interlaced counterpart with fast-motion video (like sports).

Because you’re dealing with larger video file sizes, HD video will also put greater demands on your computer. Some older computers with less processing power won’t be able to display HD video. Others will play it back, but slowly and with plenty of frustrating pauses.
What's the Difference Between Standard Definition and HD Camcorders?
Much like televisions, the difference between standard definition and HD camcorders is the video resolution. The video you see on your television or computer screen is made up of hundreds of different lines. Standard definition video will have 480 horizontal lines of resolution whereas high-definition video can have up to 1,080. The more lines of resolution you have, the sharper your video will look.There are three main resolutions of HD video available: 1080p, 1080i, and 720p.

What is “Full HD”?
Full HD is a marketing term that refers to camcorders that record in 1920 x 1080 resolution. In general, you’ll get sharper video from camcorders that record at 1920 x 1080 than you would from a 720p model.What is AVCHD?

HD camcorders come in all shapes, sizes and price points from all of the major camcorder manufacturers.

While the higher quality video is definitely a plus, it also presents a few challenges. The biggest is where to store it. HD video files are much larger than standard definition video files. That means your camcorder media – SDHC card, hard disk drive, tape, DVD, etc. – will fill up faster with an HD camcorder.See this Guide to Camcorder Memory Formats for more details on the various camcorder memory types.
