Seedance 2.5, one 30 s clip: $8.07 at 480p to $42.65 at 1080p

One 30-second Seedance 2.5 shot costs $8.07 at 480p, $17.34 at 720p and $42.65 at 1080p on Sume, in 16:9 or 9:16 (as of 2026-10-08). Seedance 2.5 is the only Seedance row in the Sume catalog that accepts 30 seconds; the other three Seedance rows stop at 15.

The ladder

The table gives the billable price of one 30 s job with audio-capable output. Each job is rounded up to the next cent after the 1.25 multiplier, so the per-second figure is an average, not a rate card.

What moves the price

Resolution is the only large lever. Going from 480p to 720p multiplies the 30 s price by 1734/807 = 2.15. Going from 720p to 1080p multiplies it by 4265/1734 = 2.46. A 480p draft is therefore about one fifth of a 1080p final (807/4265 = 0.19).

Aspect ratio barely matters: 16:9 and 9:16 have identical prices at every resolution in the grid. The one exception is 1:1 at 480p, covered in a separate post. Duration is close to linear, so a 15 s clip at 720p is $8.67, just over half of $17.34.

How to request it

Pin the id with the Video Router or with POST /v1/videos. Read the model's capabilities first: the catalog reports 4 to 30 seconds, 480p/720p/1080p, text, image, end-frame and reference inputs, and audio.

Because the price is only known after rounding, use the table above as the budget, and confirm the live number in the catalog before a large batch.

Limits of this comparison

These figures are Sume prices only. They say nothing about quality; judge that on your own prompts. Prices are subject to change when the provider list changes, so treat the date in the caption as part of the number.

Budgeting a batch

Multiply the ladder by the number of clips you plan. Ten 30 s clips cost $80.70 at 480p, $173.40 at 720p and $426.50 at 1080p. Because the 480p and 1080p prices differ by $34.58 per clip, a rule such as 'draft every clip at 480p, finish only the approved ones' decides most of the bill.

If half the drafts are approved, ten 480p drafts plus five 1080p finals cost $80.70 + $213.25 = $293.95, against $426.50 for ten 1080p clips straight away. The approval rate is your assumption; the unit prices are from the grid.

Remember that the grid is for 30 s. The same logic works for shorter clips, and shorter clips make a failed attempt cheaper, so test the prompt at 4 s first: $1.08 at 480p.

Check the number yourself

To confirm the figure behind this post, read the seedance-2.5 entry from GET /v1/video-router/models and check that 30 s and 1080p are inside its duration_seconds and resolutions. The grid price for that cell is 4265 cents ($42.65). It is the provider list price times 1.25, rounded up to the next cent for the job, as of 2026-10-08.

Use an Idempotency-Key on every create call so a retry cannot start a second paid job, then poll the job until it is complete and download the file from the result. Media inputs for Timeline or for references must be hosted files, so import them first.

None of the prices here say anything about picture quality, motion or how well a model follows a prompt. Prices can change when a provider changes its list, which is why every table carries a date. Re-read the catalog before you commit a large batch, and run one test job at the exact setting you plan to use.
