Consider the fact that your competetitors' videos may have
started with better quality (better cameras, better lighting, etc.)

AVI is a container file type which can contain compressed
(or non-compressed) audio and/or video encoded with any
of literally hundreds of different codecs. Including Sorenson.

Perhaps, but unlikely from such minimalist information.
You will need to identify actual problems in order to seek
solutions. "Murky" is not a technical description that anyone
can logically address.
- is Sorenson a better encoder,
Perhaps better than some, perhaps worse. But it hardly
seems relevant to your question as we understand it so far.
You don't even say which codec you are using now. We
could assume you are using the default DV-AVI codec and
there is nothing terribly wrong with it. Hundreds of hours
of great looking video are produced with it every day.

It is likely installable as a codec (along with the dozens
of other codecs that are already installed on your computer)

Why? What problem, exactly, are you trying to solve?

Nobody can answer (not even you) that without examining
your actual video content.
