480p

640x480 (480p) is the resolution that almost every camera can shoot at, most digicams from the last two years shoot at least 480p. Although there are lower resolutions (typically for high speed video), 640x480 should really be the lowest resolution to consider. 640x480 is a pretty good resolution, its not HD but its the resolution of standard definition television (SDTV) and a good quality source at 480p can look pretty good. Most people will be happy with this resolution but those who love the idea of widescreen, high definition home movies will want to venture into the two HDTV options. A 480p video will play beautifully on both your laptop and desktop monitors, and though it isn’t quite HD, it is definitely good enough to view on that spiffy new flatscreen TV you just bought
