Why volume
Variants multiply. The bill stays flat.
Four hooks in four settings make 16 renders. The 16th costs what the first did.
Prompts
Three prompts to start from
Each pairs a source motion with a recast. Use a clip you own the rights to.
- 01
Morning routine hook
Source motionA hand lifts a bottle to the lens · 0:12
Vertical 9:16, handheld phone look. A woman in her late twenties sits on an unmade bed in soft window light, raises an unlabeled amber dropper bottle to the lens, then dabs a drop on her wrist. No text on screen.
- 02
Parked car reveal
Source motionHands open a case, snap it shut · 0:08
Vertical 9:16, point of view from the driver’s seat of a parked car at golden hour. Hands open a matte black earbud case with no logo and snap the lid shut twice. Warm flare across the windshield.
- 03
Kitchen first bite
Source motionPour, tilt up, first bite · 0:15
Vertical 9:16, top-down on a kitchen counter, then tilt up. Granola falls from a plain kraft pouch into a ceramic bowl, berries drop in, and a man in a knit sweater takes the first spoonful. Daylight, crumbs on the counter.
Specs

Questions about ads
Can a presenter in my ad review the product?
No. A presenter can show and use your product, but can’t pose as a customer reporting results. The FTC bans reviews from people who don’t exist. Sources: FTC rule.
Is 480p good enough to run as an ad?
Use 480p for drafts and hook tests. Paid placements set minimum frame sizes that 480p vertical falls under, so render finals at 720p. Sources: TikTok ad specs.
How many variants can I render?
Up to 100 a day. One plan, $500 a month, covers them at 480p and 720p, each clip up to 30 seconds, with no credits.
Can I put a real person in an ad?
Only with their written consent, and never a public figure. Recast with characters who don’t exist, and use source clips you own. Read the acceptable use policy.
More hooks, one flat price.
One plan at $500 a month, up to 100 videos a day. Pay in crypto.
