Slop Guard

If it screams AI, it doesn't make the cut

Floating awnings. Shade with nothing to cast it. A friend who films you from the corner of the table. Viewers spot these in a second. Slop Guard checks every still and clip for the tells of AI and tells you how to fix them, before anything goes in your reel.

Real catches from real sessions

Every shot below comes from a real Hook Studio session. Each one shows what Slop Guard caught, in its own words.

An awning that hangs from the sky

A woman at a Miami cafe table under a dark awning that hangs from open skyCaught
The same woman at the cafe, filmed straight on, under a cream cafe umbrellaFixed

Slop Guard: “The awning hangs from the top of the frame over open sky and palm trees, with no building wall beside the terrace to hold it.”

Fixed: A cafe umbrella that stands on its pole.

Shade with nothing to cast it

The cafe with the awning removed, but the woman still sits in shade under open skyCaught
The woman at the cafe in the shade of a cafe umbrella, looking at her laptopFixed

Slop Guard: “The awning is gone but its shade stayed: she sits in soft, even shade under open sky while the street and people behind her are in hard sun.”

Fixed: The umbrella above her casts the shade.

Filmed from the corner of the table

A man at a restaurant table, filmed at an angle over the shoulder of the woman across from himCaught
The man at the restaurant table, filmed straight across the tableFixed

Slop Guard: “The woman who is supposed to be filming appears in the frame. The view comes from the table's side or corner.”

Fixed: Filmed straight across the table, from her seat.

Sky above the sun visors

The same woman in the driver's seat, with the car's roof lining above the visorsFixed

Slop Guard: “Sky and tree branches show through glass above the sun visors at the top of the frame. From a dash-mounted phone this reads as a camera outside the windshield.”

Fixed: The roof lining, the way a phone on the dash sees it.

A face that acts too much

A woman in a parked car with a deep, theatrical frownCaught
The same woman with a calm, slightly puzzled lookFixed

Slop Guard: “Brows heavily knitted with a deep furrow and lips slightly parted, reading as a theatrical frown rather than a calm, small reaction.”

Fixed: A calm, small look.

A card that floats in mid-air, in a clip

A frame from a clip in a car, with a white notification card of garbled text floating over the back seat, circledCaught

Slop Guard: “A floating white notification card with garbled, unreadable generated text appears in mid-air over the back seat. It is not on any screen and nothing holds it.”
