Furniture showroom reveal clip: 20 seconds on Seedance 2.5, priced

For a furniture reveal, start wide on the empty room and let the camera push in slowly until the piece fills the frame. Seedance 2.5 on Sume takes up to 30 seconds; 20 seconds is enough for a room-to-product reveal and costs $11.56 at 720p.

Furniture is a good fit for a first-frame image: send a clean studio or room photo of the piece and let the prompt handle only the camera.

Wide-to-close prompt

Keep the camera move to a single push-in. Name the material and the light, since furniture reads through texture.

• Start: "A bright empty living room with a pale oak floor and a tall window on the left."
• Reveal: "A boucle sofa in warm white is already in place against the far wall."
• Move: "The camera starts at the doorway at standing height and pushes in very slowly, straight toward the sofa, reaching a medium shot by the end."
• Light: "Soft morning daylight from the window, long gentle shadows, nothing moves in the room."
• End: "Hold on the sofa arm and cushion texture for the final three seconds."

Price for the length you need

Showroom clips fit 10, 15 or 20 seconds. The longer ones suit a slow push-in; the shorter ones suit a catalog page loop.

First frame or reference?

The Sume video docs separate the two. frame_images with frame_type: first_frame pins the opening picture, so the room and sofa you photographed are what the clip starts from. input_references guides the look without pinning a frame. For a real product, the first frame keeps the proportions closer to the catalog photo; a reference is better when you only want a color and fabric feel.

Sofa legs, seams and cushion corners are the details to inspect. A generated piece can change shape slightly during a long move, so compare the end frame with the product photo before the clip goes on a product page. Do not use generated footage to claim a dimension, a fabric or a color the product does not have.

A cheaper way to approve it

Run the reveal at 480p for $5.38 and judge only the push-in speed and whether the sofa holds its shape. If both are right, render the 720p keeper at $11.56. A 1080p version is $28.44, and it is worth it only if the clip runs full-screen on a large display.

Because Sume's video models do not take a seed, the 720p keeper is a new take of the same prompt. If the draft's camera speed was exactly right, say the speed in words in the prompt rather than counting on it repeating.

Variants for a catalog

A furniture line has colorways. Keep the prompt and swap the first-frame photo: one request per color. Three colorways at 480p for 20 seconds cost $16.14, and the same three at 720p cost $34.68. Run the cheap set first to confirm the push-in works on all three photos, since a dark sofa on a dark floor may read differently from a white one.

Keep file names and idempotency keys tied to the SKU and colorway, for example one key per SKU-color pair. A retry then returns the same job instead of a second charge.

If the product page needs a vertical version too, the price is the same at the same length and resolution, because aspect ratio does not change it on this model. Plan a separate job and a separate draft, though; a push-in that works wide may crop badly in 9:16.
