Of course, being a swiss army knife `ffmpeg` already has this capability builtin:

~~ffmpeg -i Example.mp4 -vf "select=not(mod(n\,20)),scale=200:-1,tile=5x4" -vsync 0 -frames:v 1 output.jpg~~

~~![Output image of ffmpeg, a 5x4 grid of video images](https://linux.codidact.com/uploads/mnzt6gamk3pu3pzuxcuslkzkl6t5)~~
