Question:  Will your audience be receiving a presentation by you, or
will you distribute a video for them to watch on their own?

What is your target bitrate?

Try: mencoder mf://*.jpg -mf fps=30 -ovc lavc -lavcopts
vcodec=mpeg4:vqscale=2 -o final.avi

If the quality is acceptable, we'll try to tweak lavcopts from there.
But vqscale=2 should use a constant quantizer and take of lots of
space.  As I understand it, if that doesn't look good then mpeg4 just
isn't going to look good for this source.
