What are the fetures i should see for purchasing a digital vedio camera ? How to compare with other camera ?

Check the following features;
1) Design & Dimensions: It should fit in your palm and be light enough to carry while shooting. A camera with a LCD is almost standard nowadays. The coloured LCD can be used as a viewfinder while shooting or as a screen for viewing recorded videos.
2) Lens: The broader the optical zoom range, the more shooting flexibility you'll have. Camcorder zooms start at 10X magnification, which should suffice for most users.
3) Sensor: Probably the most important feature to lookout for: The higher the CCD resolution, better the image quality
4) Recording Media: If you're gonna edit your videos on the PC, choose camera that supports the DV format, mini DV casettes or 8mm tapes. If you're not going to do a lot of editing, choose a camera that records on a DVD/CD
5) Power: With a camcorder you'd like to have a long lasting portable power, typically rechargeable batteries.
6) Audio: Cameras should have a microphone in the front preferrably recording 16 Bit sound.
There are other features, but those will depend upon your level of comfort with the technology. For starters this list would suffice.
