Lighting describes the source, direction, and quality of light in your scene. In an AI video DNA block it is the single most effective thing you can lock with text, because consistent light direction is what makes separate generations feel like the same place.
Append one lighting fragment, naming a real source and direction. Keep it identical across every generate.

Questions
What is the best lighting prompt for consistent AI video?
Name a real source and direction and repeat it identically across generations — e.g. 'overcast daylight as key from screen left, soft fill from right.' Consistent light direction is the strongest text anchor for continuity.
Why does lighting change between AI video generations?
Each generation starts fresh, so unspecified lighting drifts. Locking source, direction, and quality in a DNA block keeps separate clips reading as the same place.
