MiniDV-Compact videocassette format which records picture and sound information as digital data. MiniDV provides exceptional resolution, accuracy and color richness. Available in either ultra-compact or standard sized models, the MiniDV is smaller than Digital8. Being digital video, it has a great picture, easy editing, digital audio, and digital photo mode.
Digital8-It allows you to record digital-quality video onto a standard Hi8 or 8mm tape. This type gives you the benefits of digital video, like a great picture, easy editing, digital audio, and digital photo mode at an affordable price.
DVD Camcorder-It uses DVD media that's compatible with most newer DVD players. It delivers crisp digital video, digital editing, long lasting picture quality and they won't wear out.

STEP2- Choose the Features that you want.
Zoom- the ability to magnify your subject for close-ups, or pull back for wide shots. Most camcorders include a variable optical zoom lens, as well as electronic zoom.
Digital Photo Mode-Some digital camcorders also let you snap digital still photos, just like a digital camera.
Image Stabilizer-If you're a little shaky when shooting movies, this feature will eliminate shake, resulting in clear pictures.
