Product hero orbit in one take: a Seedance 2.5 prompt and price

A product orbit is one camera path around one object, so describe the path in a single sentence and send a first-frame image of the product. Seedance 2.5 on Sume takes 4-30 seconds at up to 1080p; a 10-second 16:9 orbit at 1080p costs $14.22.

ByteDance Seed's launch post for Seedance 2.5 (read 2026-10-05) leads with one-take creation, meaning a single generation up to 30 seconds without a cut. For a product shot that is the useful part: no cut means the object stays the same object from start to end.

The orbit prompt

Use one sentence per element and avoid mixing two camera moves.

• Subject: "A matte black wireless speaker on a pale concrete plinth."
• Path: "The camera makes one slow clockwise orbit of 270 degrees at product height, then settles in front."
• Light: "Soft overhead light, a single warm rim light from the right, no moving shadows."
• Background: "Plain pale studio, nothing else in frame."
• End beat: "Hold on the front face for the last two seconds."

First frame or references

Sume's /v1/videos route takes frame_images for image-to-video and input_references for reference-to-video. A first frame pins the opening composition; references guide the look without pinning a frame. For an orbit, a first frame at the front of the product is the safer start, because the model then moves away from a known view rather than inventing one.

The docs say that when both fields are sent, frame_images controls the mode and the request runs as image-to-video. So choose one on purpose.

Price by length at 1080p and 720p

A product orbit rarely needs 30 seconds. Most are 6-12 seconds. The table shows where the budget goes.

Request

The frame_images shape comes from the Sume video docs. Replace the URL with a public HTTPS image.

  -d '{"model":"seedance-2.5","prompt":"One slow clockwise 270 degree orbit around the speaker at product height, soft overhead light, warm rim light, hold on the front face for the last two seconds","frame_images":[{"type":"image_url","image_url":{"url":"https://example.com/speaker-front.png"},"frame_type":"first_frame"}],"duration":10,"resolution":"1080p","aspect_ratio":"16:9"}'

What to check on the result

Look at the logo or label across the whole orbit, not only the first and last frame. Generated text and small marks are where a long continuous move tends to wobble, and an orbit shows the label from many angles. If the label drifts, a shorter orbit (90-180 degrees) is cheaper to retry than a longer one, and you can lay a real label overlay on top in a later step.

Run the orbit at 480p first. A 10-second draft is $2.69 against $14.22 for the final, so three drafts and one final cost $22.29.

Because there is no seed, a 1080p final is a new take, not an upscale of the draft. Keep the prompt identical, change nothing you liked, and accept that the camera path may land slightly differently.

When 30 seconds is the right length

A 30-second orbit makes sense when the product has parts to reveal in sequence: a case that opens, a lid that lifts, a screen that lights. Then the one-take prompt becomes a timeline in words. Name each beat with a rough second mark ("around the 10-second mark the lid lifts") and keep one camera move running underneath. Sume accepts up to 30 seconds for this model, and the same request at 1080p is $42.65.

For a plain rotation, 30 seconds is padding. Ten seconds at 1080p ($14.22) shows every face of a small object, and you can loop the clip in an editor if a longer slot needs filling. Pick the length from the number of beats in the shot, not from the maximum the model allows.

One more cost rule: price does not change with aspect ratio on this model, so a square 1:1 or vertical 9:16 version of the same orbit costs the same as the 16:9 one at the same length and resolution. If you need three formats, plan three separate jobs and three sets of drafts.
