The FFMPEG guy

In the latest tutorial "How to make a video mosaic wall VFX | 2x2 3x3 4x4 quadrants matrix video effect #ffmpeg #FFMPEGGuy" available at https://youtu.be/AJ3savN4s4w, the last command was so long that it busted the 5000 characters limit of the YouTube description.

The details of command 3 for 16 quadrants is therefore posted below:
