Cool demo. The 'gm montage' step isn't working for me and I'm finding its options completely non-intuitive. I produced a series of 1979 PNGs from a 66-second video, and when I stitch them with: gm montage -borderwidth 0 -geometry +0+0 -tile x1 *.png image.jpg I get an image that is 45, not 1979, pixels wide. In fact the number of PNGs used as input and the resulting width have a nonlinear relationship: # of 1-px wide PNGs Resulting width (px) 5 3 10 4 20 5 50 8 100 10 200 15 500 23 1000 32 1979 45 Note that I made a couple changes: to speed things up I used "-vf crop=1:1080:280:0" with ffmpeg to skip the separate cropping step and output 1x1080 PNGs, and my version of gm didn't accept the -border option so I assumed you meant -borderwidth. What's up with the crazy widths on the result? What is GraphicsMagick doing?
