Y-O-X came out of a working film practice

Y-O-X was not built by people who read about film production. It came out of fifteen years of making films under exactly the constraints it removes.

Juan Manuel Biaiñ has directed, produced and edited more than seventy films for the Bertha Foundation, VICE and Al Jazeera, and was nominated for Best Feature Documentary at the Locarno Film Festival for Article 12. The tool exists because the same problem recurred across all of them, in every format and at every budget: the film that reached the screen was consistently smaller than the film on the page, and the reason was almost never a creative one.

That history is why the system is organised around departments, coverage and continuity rather than around prompts. Those are the units filmmaking actually uses, and they are the units a director already thinks in. Software designed by people who have never had to reshoot a scene, explain a schedule overrun, or cut a sequence they fought for tends to optimise whichever part of the process is easiest to model — which is rarely the part that decides whether a film gets finished.
