Texture and grain describe the surface character of the image — clean digital or analog film, plus artifacts like halation and vignette. It is the lowest-leverage dimension in text, but naming it keeps generations feeling like one roll of film.

Questions
How do I add film grain in an AI video prompt?
Name the grain character ('subtle 35mm film grain, fine organic texture') plus any analog artifacts like halation. Expect to finalize the look in the grade.
Why is texture the lowest-priority dimension?
Grain is largely governed by the model's internal processing, so text nudges it rather than locking it. It still matters for making clips feel like one roll of film.
