I use gframecatcher to generate thumbnail video galleries, i.e. something like this: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.
Fast tool to generate thumbnail video galleries for command line
command line;video
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.pngThen use ImageMagick to build your gallery image:montage -title Movie Name\nSubtitle -geometry +4+4 capture*.png output.png
