A move with high resolution and plenty of frames-per-second will look a lot nicer and more detailed on a computer screen, but will also use a lot more memory.
Another important feature to consider in the area of video capture, is whether your camera of choice supports sound. Some devices will feature a built-in microphone specifically to enhance this feature, but in many cases, you will need to attach some sort of external microphone if you want to record sound.
Other important components to look for in a digital camera are video length (how long a move can it record?), video format (a standard and easy-to-edit format like MPEG is ideal)Article Submission, and zoom (can you zoom in on things while recording a video?).
It is a good idea to ask about all of these features before buying a new camera for its video capture capabilities.
