If you have every wondered how to make a video screen shot on the command line , read on.
First of all you will need the ffmpeg package installed ( get it from ffmpeg.org )
Then you will need to run it on the command line against your video, e.g.
ffmpeg -itsoffset -2 -i mymovie.mov -vcodec png -vframes 1 -an -f rawvideo -s 120x80 test.png
-itsoffset = the number of seconds into the video the extraction occurs
-i = the movie file
-vcodec = the code
-vframes= the number of frames you want to capture.
To read more about all the options, see the ffmpeg docs
