How do you stop AI video from looking like AI?

Five fixes account for most of the gap: shorter clips (under 5s avoids warping), slower prompted motion (faces hold better), natural-light prompt language (not cinematic dramatic light), real film grain added in post, and burning all on-screen text in post (never let the AI render letters). Doing all five lifts believability dramatically.

  • Under 5s per clip — temporal artifacts hide.
  • Slow motion in prompts — faces hold.
  • Natural light, not dramatic light.
  • Post grain + warm LUT.
  • All text added in editor.

The five fixes in order of impact

1) Cut clips under 5 seconds — most AI artifacts emerge after that. 2) Prompt slow, subtle motion — faces and limbs warp under speed. 3) Use natural-light language ('window light', 'overcast') over dramatic-light language ('neon noir lighting'). 4) Add film grain post — 5–10% in CapCut or Resolve. 5) Burn all on-screen text in your editor — never let the model render letters.

Pick the right model for the shot

Half of the 'looks AI' problem is using the wrong model. Faces in close-up → Veo 3. Human action → Kling 2. Crowds → Sora-class. The wrong model produces uncanny output no matter how well you prompt.

FAQ

Can I make AI video that fools an expert?

Fooling an expert is hard. Fooling a phone-scrolling audience for 6 seconds — already routine in 2026.
