The increased pixel-count in the 1-chipper often results in a sharper

motion-video image than usual, with better color. It also generally

results in reduced low-light range, and sometimes also in worsened

image motion-artifacting. (For more on this, see:

www.David-Ruether-Photography.com/vid_pict_characts.htm - and for a

comparison of the images of various types of 1 and 3-CCD images

under different lighting conditions, see:

www.David-Ruether-Photography.com/camcorder--comparison.htm .) In general,

3 CCDs gives a sharper picture with better tonality and color, with

less motion-artifacting (all else being equal), though the best 1-CCD

cameras are getting good enough to rival some 3-CCD cameras for

some purposes (and at least one recent 3-CCD model suffers the

tonality problems and limited low-light range of the worst 1-chippers...).

This is not due to HD space, but can be due to not having a dedicated

video-files drive, to drive fragmentation, and to having programs

running in the background (anti-virus programs especially) - among

other possibilities...
