I think what he and I would like to know is how the
keyframing in
the AVI codec is used, and to what it should be set. I am
assuming it has to do with an assistance to video compression, and
maybe temporal anti-aliasing.
Configuring the codec:
Some codecs accept quality, data rate, and
key frame interval parameters. The higher the quality, generally the
slower the codec runs and the larger the output, but the better the
video looks after compression. By setting a data rate, you request
that the codec attempt to produce output at a fixed size-per-time
ratio, set in kilobytes/second.
And by setting a key frame interval,
you are enforcing that seek points are placed at regular intervals
in the video in order to reduce wait time when seeking.
Nearly all codecs support additional parameters, which can be set
by pressing the Configure button. The dialog that appears is
codec-specific; please consult the documentation for each codec for
further details.
BTW, I highly recommend Virtual Dub for a free video editor. I
rendered a 1:43 uncompressed AVI last night, and it ended up being
2.6 GB. I tried running it in WMV and in the Inmatrix.com
ZoomPlayer, and it did not play in either. It opened up in Virtual
Dub and plays just fine. Now I can use VDub to edit together or cut
up, filter, reduce, compress to one or more of a dozen codecs,
change brightness/contrast on the whole video, etc.

P.S. I assumed incorrectly above. See below.
I stand by the post I made in this thread http://forum.solidworks.com/fo...ord1=key%20frame#11707
