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
Not really all that informative, but I thought somebody might be
interested in hearing about it.
On2 VP3 18.104.22.168
Positive: extreme low bitrate imaging efficiency
Negative: fine detail blurring, fixed setting decoder
Note: On2 VP3 is not a MPEG-4 codec. It has been included to offer a
proprietary codec comparison
. 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.
