right, here are my settings and results:
length: 23 minutes
size: 50 mb
resolution: 800x600
codec: avi, techsmith (designed for capturing tuts/software)
framerate: 5pfs
audio: 3 kb ps
i think it should be possible to get the filesize down at least 10-15 mb, video tutorials on 3dpalace.com are much smaller, but use the same codec and similar settings..
