Audiences have developed a sharp eye for "AI slack" — the subtly wrong physics, texture and timing that reads as cheap even when people can't name why. Keeping AI-assisted VFX on the premium side of that line is mostly craft. Here's where the tells hide and how we handle them.
The usual tells
Weightless motion, textures that are too clean or too busy, light that doesn't match the plate, edges that shimmer, hands and text that don't hold up, and timing that feels ever-so-slightly off. Individually small; together they scream "generated."
Guardrail one: integrate, don't paste
Generated elements almost never sit right on a plate straight out of the tool. We relight them to the scene, match grain and motion blur, and grade them into the shot so they share the same light and lens character as everything else. Integration is where cheap becomes convincing.
Guardrail two: humans on continuity and finish
We keep people firmly in charge of continuity, edit rhythm, sound and final grade — the places AI drifts and the places the eye judges quality. AI does the volume; humans defend the taste.
Guardrail three: know when to shoot instead
Sometimes the honest call is that a shot will never hold up generated, and the fast route is a real capture or CG build. Knowing where that line sits — and not crossing it to save a day — is what keeps the whole piece credible.
The bottom line
The difference between premium and uncanny isn't the model; it's the craft around it. Integrate every element to the plate, keep humans on continuity and finish, and shoot the shots that need shooting — and AI-assisted VFX simply looks like good VFX.
