39:1 aspect ratio.) If your
botched video clip has, say, a resolution of 400?— 400 (giving you a 1:1
aspect ratio and a square video frame), you can either increase the width to
600 (400?— 4/3) or decrease the height to 300 (400 divided by 4/3). Of the
two choices, decreasing the height will usually give you a sharper-looking
video, since compressed pixels always look better than stretched pixels.

Synchronize audio and video. Does this happen with all videos, or just
one? If only a single video clip is out of sync, then you??™ll need to repair it
using a timeline-based video-editing application like Adobe Premiere
(www.adobe.com). (Windows Movie Maker, which comes with Vista,
won??™t do.) Drag your video to the timeline, then drag the audio portion
of the clip slightly to the left or right until it??™s synced up with the video.
(Naturally, this will take some trial and error, so I hope it??™s not too boring
of a clip.) When you??™re done, export the project into a new movie
file. Consult the documentation that comes with your video application
for details.
If you??™re watching a DVD and the audio is out of sync, try
pausing playback, waiting a few seconds, and then starting
up again. Sometimes that??™s all it takes to get a movie back on
track.
If all your videos are out of sync, it??™s usually caused by a problem with
your hardware drivers.
