# Director's rack

> The director's rack is eroq's set of look controls — film type, era, tempo, camera gear, lens, aperture, palette, lighting — folded into every prompt server-side so a whole film shares one aesthetic.

Each choice is a short, engine-tested phrase; combined they describe a production design without the prompt turning into jargon.

## On eroq

Set once in Film mode for every scene, or per clip in Quick mode; the API takes the same fields (film_type, era, tempo, camera_type, lens, aperture…).

## FAQ

### Do rack choices cost credits?

No — they are prompt engineering, folded in for free.
