I appreciated the link to
although, as Freun said, it was "Not really all that informative,..."
Is anyone aware of a site that has a downloadable video clip that was created
for comparison purposes with different video codecs (MPEG 1, 2, 4, divx,
Windows, Real, VP3, VP4, VP5, and so on)? Preferably, each of the video
clips would be created from the same "reference" video file, that would be
about one minute long, and would consist of a mix of high speed action and
The site should also have links to locations from which the video player
software for each of those codecs can be downloaded. That way, each of us
could install the required player software, and download and play the
reference video clips. That would allow each of us to be our own judge of
the various codecs.
Perhaps the site which contains the downloadable video clips would also have a
table that summarizes the information for each codec; such as,
* name of codec,
* size of the reference 1 minute compressed video file
* time to compress the 1 minute clip on reference hardware
* minimum hardware requirements for full screen, best quality software-only
* rating of quality on a scale from 1 to 10 based on votes from people who
have downloaded and played the 1 minute reference video clip
If such a site does not yet exist, I would be willing to help set it up.
