Quote a 30-second AI video clip: Seedance 2.5 per clip and per minute

A 30-second 16:9 Seedance 2.5 clip costs $8.07 at 480p, $17.34 at 720p and $42.65 at 1080p on Sume. Two such clips make one minute, so a rendered minute at 720p is $34.68 before retakes.

For a client quote, price the retakes too. The number a finance team needs is the cost per accepted clip, not the cost per render.

Where the numbers come from

Sume bills the provider list price x 1.25, rounded up to the cent. Seedance is priced by video tokens: width x height x duration x 24, divided by 1,024, charged per 1,000 tokens. The rate per 1,000 tokens for 2.5 is higher at 1080p than at 480p and 720p. The values in this post are the price book's output read on 2026-10-05, not a quote from ByteDance.

The quote table

Per clip and per minute of finished video, 16:9, no retakes.

Add a retake allowance

Plan for retakes. If you accept one clip in three, the cost per accepted clip is three times the render price. At 720p that is $52.02 per 30-second clip. If you proof at 480p first and render only the accepted prompt at 720p, three proofs plus one render is $41.55.

The accept rate is yours to measure on your own prompts. Do not borrow a number from a post; run ten prompts, count the keepers, and use that.

What changes the price

Four things change a clip's price on Sume.

• Length: price scales with seconds. A 15-second clip at 720p is $8.67, about half of 30.
• Resolution: 1080p uses a higher token rate.
• Aspect ratio: the pixel count changes slightly between 16:9, 9:16 and 1:1 on some sizes, so check the row.
• Reference video: a reference video bills at a reduced rate, with a 15-second input length assumed, per the price book.

Estimate in code

Before you spend, call the catalog and read the row; then submit once you have a number.

A worked quote

A client wants a 90-second brand film at 720p, 16:9, made from three 30-second one-take clips. Render cost with no retakes is $52.02. With a one-in-three accept rate it is $156.06. With 480p proofs first and one 720p render per scene, assuming two proofs per scene, it is $100.44. Show all three on the quote so the client sees what the proofing step saves.

Why 30 seconds is the unit

A 30-second clip is the longest single Seedance 2.5 request on Sume, so it is the natural unit for a quote: one render, one price, one decision to accept or retake. Shorter clips (10 or 15 seconds) are cheaper individually, but a scene made of three 10-second clips has two cuts the viewer sees, where one 30-second take has none. If continuity is part of what the client is buying, say so in the quote, since it is the reason to pay for the longer take rather than stitching short ones.

For a rough check, a 10-second clip at 720p is $5.78, so three of them is $17.34 against $17.34 for one take. The price is linear in length here, so the difference is the cuts, not the cost.

What to put in the quote

List the model id, the resolution, the length, the per-clip price and the retake allowance as separate lines. Put the read date on the page so a reader knows when the price book was checked, and say that prices follow Sume's catalog at the time of the job.

Do not quote a per-minute price for a single render: a model that makes 30 seconds in one take produces half a minute, and a minute is two renders plus the join. If your scene needs a continuous 60 seconds, the Sume catalog for this model does not give it in one request.
