Digital Movie Camera

I recorded a video camera using the Cybershot digital camera, recording when I used the setting to 160 for example to format e-mail. video clips is unclear. I want to make a film that is the best quality and make the videos not to be blurred. How can I do thata

I do not know if you can improve the quality if you saved the original movie in low resolution. Your best bet is to play the movie in small window to keep the clarity.
