Take the tour ×  I use gframecatcher to generate thumbnail video
galleries, i.e. something like this:  enter image description
here  However this is a GUI tool and I want to create
recursively a gallery for every video in a directory structure,
so I am looking for a fast command line tool to do this.

down vote accepted  Pull out the image captures (these are 100
pixels tall, and keep aspect ratio), the rate (-r) is per-second
(this yields one frame every ~5 minutes), this also adds time
stamp to output image.  ffmpeg  -i MOVIE.mp4 -r 0.0033 -vf
scale=-1:120 -vcodec png capture-%002d.png  Then use ImageMagick
to build your gallery image:  montage -title "Movie
Name\nSubtitle" -geometry +4+4 capture*.png output.png

has utilities for stuff like this.   There are API libraries
using imagemajick for a bunch of languages too.  share|improve
