Date: 2008apr28 OS: Linux Q. How can I make a thumbnail of a movie? A. Use ffmpeg like this:

ffmpeg -y -i input_movie.avi -f mjpeg -ss 10 -vframes 1 -s 150x100 -an thumbnail.jpg

The options break down like this: -y Yes, overwrite the output file -i <file> Name of input video -f <format> Output format -ss <seconds> Skip in <seconds> for frame -vframes <n> How man frames to grab. We just want one. -s <width>x<height> Size of the thumbnail -an Disable audio
