This is a "printed" version of the video

A flour bag or something that looks like it, is dropped and falls on a floor that looks like the map of a city. Voices over talk about the process of making an image that works. And subtitles reveal a conversation between two people: dropping the "flour bag" or making the "image".
Actually, the viewer really only sees an explosion over a city.

The whole picture is about making the ending work

And to make the ending work, you need wonderful actors

This could happen anywhere...Africa, Europe or America

This movie is about love

This sequence was shot in the studio
