[magick-users] Problems with convert

[David Vanderson]

Hi Michael,

It sounds like you might want an actual movie.  I've had good 
experiences with using mencoder to do this.  See 
http://www.mplayerhq.hu/DOCS/HTML/en/menc-feat-enc-images.html for a 
start.  You might have to convert the gifs to pngs first.

I got a nice video from your data with:

for i in *.gif; do convert $i $i.png; done
mencoder "mf://*.png" -mf fps=25 -o output.avi -ovc lavc

Let me know if it works for you.

Thanks,
Dave
