Tumblers: save the cup as a reusable product, then buy motion

Register the still as a product. Condensation beads are a different generate, not a new cup.

A tumbler ad that holds is the same lid, the same print, the same powder coat, moving. It is not a new vessel every time you want frost on the wall. Upload the approved pack shot once. Reuse the key. Then buy a motion pass for beads, ice, or a slow orbit. Regenerating "a branded tumbler with condensation" from a paragraph is how the wrap drifts and you are selling a cousin mug.

Register the cup before you animate it

Set up reusable characters and products is the named agent job. Upload once per product. Reuse across every scene. The tool opens an Asset Builder card for reference images of a character, product, prop, or location. Batch opens several cards when you have the cup, the lid, and the sleeve. Required: key, suggested name, type, description, plus exactly one of a workflow id or a slideshow schedule id. Assets belong to that build, not a global pool. Uploading does not use generation credits. Generation uses the keys later.

The stills are the brief. Front, three-quarter, lid on, lid off if the listing sells both. Same light family. Do not mix a lifestyle picnic snap with a pack-shot hero and call it one product — that average is a third cup. A logo in the brand kit is not the wrap. The wrap that has to match across twelve shots is a reference asset.

This is drinkware, not a juice menu and not a generic catalog. Juice bars sell a drink in a cup they may not manufacture. Ecommerce storefronts get a different page. This page is the tumbler SKU: wall, lid, print. A water-bottle job is a different split (cap click versus sleeve identity). Do not borrow that brief.

Condensation is a second generate against the same key

Once the cup is registered, motion is image-to-video, not a new still. Image-to-video starts from the frame you already approved. Frame one is the file. The print, the lid geometry, the powder color survive because they were already in the picture. The prompt is for physics: beads forming on the wall, a slow rotation, ice settling. Re-describing the cup in the prompt is how the model starts drawing a second cup.

Seedance 2.5 is the still-to-motion family on that job: 4–30 seconds, 720p, 47 credits, native audio. The published URL is the family page, not a separate I2V slug. Beads and a drip need a few seconds, not a thirty-second single take of a new kitchen. Iterate short. Audio is on — write a quiet condensation bed or write silence; a silent brief can still get a soundtrack you did not choose.

Do not prompt a new print. Do not prompt a different lid. Do not prompt "make it look colder" if that sentence also changes the wrap. Beads are weather on a locked SKU. A new cup is a different SKU.

The AI product video generator wraps the same still-to-motion idea around a product brief. It does not replace the asset card. Register first. Then run.

What this is not

It is not text-to-video "a cute tumbler sweating on a marble counter." That sentence has no plate. The model will pick a wrap from the average of every cup it has seen. Average is not your SKU.

It is not a one-off upload per ad. If Monday's condensation pass and Thursday's orbit do not share a key, you bought two cousins. The waste is identity, not motion.

It is not a lifestyle film of a person drinking. A constructed spokesperson on a wellness line is a different job, and a health-adjacent mouth is a problem you do not need. Hold the cup. If a founder has to talk, that founder is real, on a different day, cut after the beads.

It is not "fix the wrap in the motion prompt." If the print is wrong in the still, reshoot or recrop. Animating a bad pack shot freezes the miss for the whole duration.

The test

Is there a cup that must be the same pixels across more than one shot?

Yes: this job, first. Open the card. Save the key. Then buy beads, ice, or orbit as a later generate against that key.

If it is a one-off extra that will never return — a competitor cup in a comparison, a prop in the background — skip the registry. If it is a hex on the brand kit, use the kit. If it is a standing rule with no file ("always 9:16"), that is memory, not an asset.

Monday's condensation and Thursday's lid-off hero should be the same vessel. If they are not, you did not register the product. You generated two ads.

FAQ

Does registering the tumbler spend credits?

No. Uploading reference assets does not use generation credits. Credits apply when you run a later image or video model against the key, at the cost shown before you confirm.

Can I skip the asset card and attach the pack shot to every I2V run?

You can. You will re-upload, and nothing binds those stills to a key the scene director can reuse. The card is the collection step. Skip it and the product is not in the workflow.

Why is condensation a different generate from the cup?

Because the cup is identity and the beads are weather. Regenerating "tumbler with condensation" as one text-to-video paragraph redraws the wrap. Lock the product still, then animate beads on that still.

Is Seedance 2.5 the only motion row?

No. It is the still-to-motion family this brief uses: 4–30s, 720p, 47 credits, native audio, published at /models/seedance-2-5. A different I2V row is a different confirm. Change the row when the job changes, not because the last cup looked "more cinematic."
