Compression Options for AVI

Remember that you have two AVI types you can create. Uncompressed
and Compressed. An Uncompressed AVI has no Compression so that
feature has no function.

Compressed AVI files, however, can use a very wide range of codecs. When
you select AVI – Compressed as your Format you will find a different list of
Compression options available to you. This list is entirely based on what
codecs you have installed on your PC. For example, if you wanted to
encode your AVI with DivX, you must have the DivX encoder installed on
your PC. If that is installed it will appear as an option in the Compression
dropdown list.

If you’re someone who frequently works with video you’re going to find
that AVI – Compressed gives you the most flexibility in what codec you use
for the compression. Pick the one that works best for you.

Compression Options for MPEG1 and 2

When you choose any MPEG video type as your Format you will have
access to the standard MPEG Video compression method. This uses the
MPEG encoder installed on your PC.

Most of the adjustments that you make to MPEG compression are done by
clicking on the Settings button to the right of the Compression dropdown
list. This window contains the precise adjustments you can use for creating
the video.
Settings contains settings for Bitrate, Interlacing, and Group of Pictures
(GOPs). The simple explanation is that if you know what these options are
you can change them. Most videos of all kinds will work with the default
settings used here. They should only be changed by advanced users who
are familiar with how these settings impact the video.
