                Screensheet maker for Linux bash and Windows CMD.EXE
              
          
    screensheetmaker


Consists of two scripts: make-screens.sh for Linux bash and make-screens.cmd for Windows CMD.EXE.
Uses ffmpeg, and montage and convert from Imagemagick package, additionally bc under Linux.
Works pretty fast. The approach is to divide the file into N intervals, one for each picture and pick the first keyframe after the midpoint of each interval. This is done quickly with a single run of ffmpeg, given the duration of each interval.
Known limitations: Length of the video. The shortest video I've run with success was 30 seconds, though the number of screens was limited (by the number of keyframes in the video).


make-screens.sh
