This is a bash script meant to create video contact sheets (previews) of videos. Any video supported by mplayer and ffmpeg can be used. A note of warning: Unlike most similar tools it, by default, makes screenshots the same size as the video, see below for details on how to change this.
Take a look at the documentation and/or use the --help
and --fullhelp
options to learn how to use it.
