I want to thank all developers of imagemagick, because imagemagick does most of the magic in a little tool i made.
Take a look at this image:

The whole compositing is done with IM.
ffpoth, thats the name of the tool i made, takes still images from video files and writes them to standard output as PPM.

Without IM it would be MUCH harder to montage multiple thumbnails with text and timestamps. (i've tried it...)
Thank you!
