If you have ever been through the process of editing video on your
PC and output it as a single file, you have undoubtedly faced the
question of "which video format should I choose?". A simple
question that is sometimes not so simple to answer. For those who
want to put their videos online, there aim is to find a format that
can compress the video file as much as possible, but without sacrificing
video quality. For those wanting to watch their videos at home on
the TV, they want to produce their movie masterpieces in a format
with the best video quality, but with a file size suitable to burn
onto a CD or DVD. These scenarios are something that almost everyone
will face at one time or another, when producing movies on the PC,
and in order to make the right decision you need to have all the
facts. The following are some helpful tips to guide you in the right
direction.
The first thing you should keep in mind at all times is: "always
keep the original video file in the highest quality format".
Whether you are outputting your video into a web streamable format,
or burning it onto a CD/DVD, always remember to preserve the original
video file in high quality. In general, DV-AVI video files have
the best video quality. However, please note that 60 minutes of
video can take up almost 12GB of hard disk space, so be sure to
have enough storage space. The next best thing to DV-AVI is using
a high quality MPEG-2 compressed file format, which enables you
to save up to 2 hours of high quality MPEG-2 video onto a single
DVD disc (4.7GB).
With streamable video formats (such as Windows Media Video, QuickTime,
and RealVideo) you can save a lot of disk space, but these files
(once output in streaming format) cannot be restored or edited.
Streamable video formats are still greatly used by many people because
they offer reasonable quality, small file sizes, and allow you to
send videos via e-mail (if within a reasonable size) or place on
the web for easy viewing anywhere in the world.
Now that you have an understanding of the basics, view the various
