I'm also using ffmpeg to work with images, like creating thumbnails from full-sized images. Basically, what you would use imagemagick for. I just haven't discovered yet scenarios where imagemagick does something better than ffmpeg (my use-cases are pretty simple, though). And since I also work with videos, I feel like I have to learn just one command-line monster instead of two.<p>I'd be interested in use-cases where imagemagick should be strongly preferred over ffmpeg.
