Media Player Video Quality Issues and Hardware Acceleration |
|
|
Hey Gang,
I've produced a user training video series for viewing over the web using
encoder and .wmv files. For the most part the results have been good but a
few users experienced very poor video quality (blocky, large pixels etc.).
In most cases, reducing hardware acceleration in Media Player resolved the
issue.
My question/concern is that there are a number of users that have had no
problems despite their media player settings being set to the default full
setting. Also, one of the users that did need adjustment has never had any
problems viewing any other video file.
Is there something I can adjust in the production of the file in encoder
that will make the .wmv more forgiving of a users media player settings? We
have a large user base that will be accessing the video and I'd like to avoid
instructing them to make media player (or any other technical) adjustment if
I can.
Thank you in advance!
Wayne

The only setting that can affect hardware accelerated
rendering I can think of is the frame dimensions. To be on
the safe side, you should make the width and height a
multiple of 32. The height may also be just a multpile of 8
or 16, but 32 is the safer. Those are common limitations of
the video hardware. Older video cards moreover can only
create small overlay surfaces, 352x288 or something like
that, because of video memory a DAC speed constraints.
