Retainer cases: I2V the hinged box, not the aligner-tray SKU
Seedance the clamshell you stock. Aligner-packaging already spent the clear tray. /for/orthodontists is the chair. Do not regenerate the vent holes.
Seedance the clamshell you stock. Aligner-packaging already spent the clear tray. /for/orthodontists is the chair. Do not regenerate the vent holes.
A retainer-case listing that ships is this hinge, this latch, the vent grid a buyer already owns in a bathroom drawer. Motion is a hold on that box. The clear tray is a different SKU. The consult chair is a different audience. Photograph the clamshell. Animate that photograph. Leave the tray to the packaging post. Leave the teenager to the practice page.
Photograph the hinged box you stock
Shoppers match plastic, not atmosphere. Colourway, hinge knuckles, the latch they press every night, the vent holes that keep the case from steaming shut, the wordmark on the lid. Text-to-video of “premium retainer case on a sunlit vanity, fresh orthodontic feel” invents a cousin clamshell and a tray you do not mould. That is a different listing.
Shoot the approved unit the way you would print a hangtag: square-on or a three-quarter that still reads the hinge and the vents, even light, no invented bathroom. If the only snap includes a child’s mouth, crop it or shoot again. Facility stills are the allowed picture: carton, closed case, open clamshell on a card. Fit belongs on a consented practice still, not in a packaging generate.
Image-to-video starts from the frame you upload. Prompt camera and physics: a slow orbit, a lid lift that stays this latch. Do not re-describe the case. Re-describing is how the model draws a second hinge.
Seedance 2.5 holds the clamshell
Stitching four short clips is how the vent grid jumps. Seedance 2.5 is the family hold: 4s–30s in one pass, 720p ceiling, listed 47 credits, native audio. Image-to-video is the still-to-motion job on that family. The published URL is this slug, not a second Seedance path. Qualities listed: 480p and 720p.
Write only travel. “Locked clamshell, slow orbit, hinge static, vents readable, no new latch.” Stop. “Show a patient seating a retainer into the case after dinner” is a health persona. Native audio is on. Write a quiet pad, a lid click, or silence. A silent brief still gets a soundtrack you did not choose.
Iterate at 4s or 5s until the vents hold. Thirty seconds is the identity ceiling, not a default. Optional last frame only when you have a second approved photo of the same SKU — open clamshell, then the closed carton. A last frame of a tray series is a morph.
Do not ask Seedance to letter “nightly wear” on the lid. Add a text overlay to a video burns one authored line for the whole clip. Overlay after picture lock.
Aligner-packaging already spent the tray; the chair is a different audience
Aligner packaging is the clear tray still, not the ortho chair already owns the scallop: attachment dimples, the tray on a card, the carton lockup. That is a mould job. This page is leftover plastic around a finished retainer. Do not rewrite that post as a hinged box. Do not Seedance a clear tray in the same pass as the clamshell and call the middle “our case.”
If a sentence in the brief contains “scallop,” “attachment map,” or “aligner series,” you are on the tray post. If it contains “hinge,” “vent holes,” or “clamshell,” you are here. Mixing them is how a case SKU grows a cousin tray in the well and a latch you do not tool.
Orthodontists is the chair: a parent weighing cost and duration, a teenager weighing how they will look at school. Film ideas are a consented treatment timeline, a scanner on a staff member, a debond reaction. That is the practice calendar. A packaging team does not inherit it.
Photoreal talking presenters on health are a YPP kill. A constructed orthodontist, a generated teenager, a fake clinician holding your clamshell — those are personas plus health advice. Do not generate gums or a patient body to “show the fit.”
Do not regenerate the vent holes
The failure mode is a beautiful orbit of a different SKU. A 12-hole lid becoming 16. A living-hinge becoming a pin. A latch walking half a millimetre. Those are claims. A shopper who already owns the pack will notice before they notice your caption.
Prompt camera only. Do not write “make the vents look more premium.” More holes is a different part. If you needed a second SKU — youth versus adult, mint versus navy — photograph the second box. Do not first-last a small clamshell into a large one. Two different objects is a morph.
If the only photo is a phone snap of an open mouth with a blurry case on the nightstand, that is a practice still. Shoot the box on a table, vents facing camera. Pause on the grid. If you cannot count the holes, you are not done.
The test is a pause. Hinge, latch, vent pattern match the unit you stock: packaging. Chair and scanner: /for. Clear scallop: the tray post. Invented mouth: you asked a talking row to be the carton.
FAQ
Can I text-to-video a retainer case on a bathroom counter and skip the box photo?
You can. You will get a cousin clamshell and a vent pattern you do not tool. OEM is the box you photographed. Seedance 2.5 via image-to-video from that still is the hold.
Is this the same as the aligner-packaging tray post?
No. That post holds the clear tray: scallop, dimples, carton. This page is the hinged case around a finished retainer. Keep the vents. Leave the tray. Leave the chair on Orthodontists.
Does Seedance 2.5 add a soundtrack if I do not ask for one?
Yes. Native audio is on. Write a quiet pad, a lid click, or silence. A silent brief still gets a mix. Quoted SKU talk in the prompt does not become a title card.
Can I generate a patient putting the retainer in the case if I crop the face?
No. You are still minting a body in a health category. Keep gums and faces out. The SKU is the clamshell on a card. Fit belongs on a consented practice still, not in a packaging generate.
