In a live-action commercial the pack shot is the hold at the end: the SKU, the logo, the claim, often a locked-off hero. In a generate it is usually the input still. Image-to-video treats that still as frame one. The still contract is the rule that the clip must keep being that product. A reference image is a looser object — identity without locking the frame. Mixing the two slots is how a label that was sharp in the PNG becomes a suggestion in the MP4.
UGC-style ads live or die on a readable pack. Hands, type on the carton, the lid physics: those are the three failure modes. Prompting 'cinematic orbit' on a pack still is how the logo crawls. Lock the camera, keep motion on the hands or the pour, and cut to the still you own if the model warps the type. A talking head holding a melted bottle is worse than a tabletop with no face.
Generate the still until the label is right; retrying a frame is cheaper than retrying a clip. Then write motion, not a re-description of the box. The pack shot is proof. Lifestyle B-roll can be invented. The SKU cannot.
In practice
- Approve the still for readable type before you animate it. A soft label will not sharpen in video.
- Prompt what moves around the pack, not a new pack. Re-describing the product fights the frame you already have.
- If the generate warps the logo, cut back to the still. Do not 'fix' the SKU in the prompt.
The mistake to avoid
Treating a pretty lifestyle generate as the pack shot. If a shopper cannot read the product, you do not have a pack shot.

Image-to-video animates a still you supply: the picture becomes the opening frame, and the prompt describes only what happens next.
UGC

Still contract
A still contract is the rule that an image-to-video clip must obey its input still — identity, product, framing — rather than drifting into a new picture.
Hook rate
Hook rate meaning: the share of people shown a video who are still watching a few seconds in. It grades the opening, not the body.
