The site:


has a review & comparison of several mpeg-4 codecs, and they also
include vp3.  (Be warned, it's a very big web page, due to all of the
image examples!)

Not really all that informative, but I thought somebody might be
interested in hearing about it.

On2 VP3

Positive:  extreme low bitrate imaging efficiency
Negative:  fine detail blurring, fixed setting decoder
Settings:  defualt

Note:  On2 VP3 is not a MPEG-4 codec. It has been included to offer a
proprietary codec comparison

And later

.  On2 VP3 provides great quality for extremely low bitrates, though
this is not a MPEG-4 codec.  It appears this proprietary format scales
better at low bitrates, while MPEG-4 rapidly taking over for image
quality once bandwidth reaches 1000+ Kbps ranges.  Due to the nature of
its format VP3 tends to blur images as data rates fall instead of
creating macroblock artifacts like MPEG-4.
