Foil: the box cutter is the SKU; tear sound is Vidu

Identity-hold the carton. Diegetic tear is a second row if you need ASMR. The metal saw on the box is the product. A kitchen that happens to contain foil is a lifestyle ad. Photograph the carton you ship. Animate that photograph. If the clip must crinkle, buy native tear on the same pass.

The carton is the identity

The cutter is a stamped edge. It has a pitch, a colour, a plastic housing, a place the sheet exits. Those details are the listing. A paragraph that says “aluminum foil box on a marble counter, satisfying tear” is not a spec. It is a request for someone else’s pantry and someone else’s saw.

Ecommerce brands already have a page for catalog motion and PDP loops across a whole store. That is a general brand surface. This post is the foil carton. Do not rewrite the ecommerce page as a kitchen film. The box on the table is the commercial.

Photograph the carton large in frame. Include the cutter and the lockup if it must read. If the still would fail a listing audit — crushed corner, a hand covering the saw — stop. Motion will not restamp the metal. Argue about identity at image prices. Then buy seconds.

Animate the still, not a kitchen

The AI product video generator is built around a locked pack. Image-to-video keeps frame one as the file you sent. Prompt only the delta: a sheet leaving the cutter, a slow push on the saw, a finger that was already in the still if a real hand is in the photo. Do not prompt “cozy kitchen, golden hour, meal prep.” That sentence is how the carton becomes a prop in a room you do not own.

Identity-hold means the generate is not allowed to “improve” the die-cut, restyle the lockup, or grow a second roll. Those are claims. A buyer who already has the box on the counter will notice a different lip before they notice your logo.

If you needed a lifestyle plate, shoot it. A real counter with the real carton is a still you can animate. A generated marble island is a cousin brand. Two files. Cut them.

Crop the still to the ratio you will ship. “9:16” in the prompt does not recrop a 16:9 pack shot. Recrop, then generate.

Tear sound is Vidu’s native mix

Vidu Q3 Image to Video is the row when the still is already the carton and the job includes diegetic tear. Image required. Category is image-to-video only. Audio is on. Durations are only 5s, 10s, and 15s. Max output 1080p. 16 credits listed; the row is marked discounted.

Native audio means soundtrack and frames from the same pass. Tear is the textbook case: the sheet is visible, so the crinkle has to be audible in the same denoise. Retrofitting a “foil rip” sample onto invented motion is how the sound lands on the backswing.

Write the mix into the 5s prompt. Name two or three sounds: sheet through the cutter, metallic zip, box board flex. State “no speech, no music” if you want clean foley. Leave audio unspecified and Q3 invents a mix — kitchen murmur, a music bed the carton never had. A silent brief still gets a band. You do not get a mute plate on this slug.

Five seconds is the shortest legal clip. There is no 3s retry on Q3. Do not pad to 15s because the slider has two more stops. A discounted 15-second miss is still a wrong carton with a soundtrack attached. 1080p is the ceiling, not 4K.

If you do not need ASMR, you still identity-hold the carton. Write “no music, no speech, quiet room.” You cannot skip the still. Q3 will not find your cutter in a paragraph.

What this is not

It is not a talking host explaining “heavy duty versus standard.” That mouth is a presenter. Generate the carton. Type the grade after picture lock if you must letter it. Video models do not typeset legal copy on foil boxes.

It is not a text-to-video “satisfying ASMR foil tear, cinematic.” That invents the saw. The saw is the SKU.

It is not a one-still wiggle that leaves the sheet sitting in the box. If the sheet must move, say so, and keep the cutter in frame.

It is not a second generate that “adds the tear later.” Diegetic tear is this row, this still, this mix, born together.

Caption after. Five seconds of native audio is not a subtitle track. If muted autoplay still needs a SKU line, burn type you authored. Do not ask Vidu to letter the panel.

FAQ

Can I prompt a foil tear from text and skip the carton photo?

You can. You will get a box. It will not be the box often enough to ship. The cutter is the spec. A paragraph is not a spec for a saw.

Does Vidu Q3 require an image?

Yes. Image-to-video, image required. Durations 5s / 10s / 15s, 1080p, 16 credits listed, discounted, native audio on. A text-only generate is a mislabel.

Should I mute Q3 and drop a stock tear on top?

No. Audio is on. A “silent” brief still gets a mix. Write the tear you want in the prompt, or write that you want quiet foley only. Replacing the native crinkle with a library sample is two files pretending to be one event.

Is this the same as a general ecommerce product loop?

No. Ecommerce brands is the store-wide surface. This page is the foil carton and the cutter. Identity-hold the box. Buy tear on Vidu only when the still is already the SKU.
