Will my AI prompt look cheap?

Heuristic checker: it grades your words, not your footage. A high score doesn’t guarantee a great render — but it kills the obvious cheap tells before you burn credits.
Seven weighted checks — each one a documented reason AI video looks cheap. Weights shown per check.
“A man” means whatever the model feels like. Named age, build, wardrobe, and marks lock the casting.
The #1 cheap tell. A named light source with mood and quality beats “well-lit” every time.
No camera move = slideshow. A push, orbit, or track adds the motion cheap footage lacks.
Close-up, wide, low angle — without a named frame size, the model guesses and plays it safe.
Scenes need a ground to stand on. Floating subjects in vague voids scream “AI”.
Surfaces sell reality. Dust, rust, rain-slicks, chipped paint — the micro-detail flat prompts skip.
One action per 5–10 second clip. Cram in three and nothing gets enough frames to look right.
