Monthly budget for 30-second Wan 3.0 clips: 4, 12 or 30 a month

Four 30 second clips a month on Sume's wan-3.0 cost $15.00 at 720p, twelve cost $45.00 and thirty cost $112.50. Those figures are 30 seconds times $0.125 a second per clip, which is $3.75; at 480p the rate is $0.0625 and at 1080p it is $0.25.

The base table

Plan the month in clips, not in seconds. A weekly series is four clips, three a week is twelve, and a daily clip is thirty. Each is priced at 30 x the Sume rate (provider list x 1.25 from the repository pricing tables).

Add a retry allowance

Retries are the line most budgets forget. A model produces a clip you reject some fraction of the time, and we have no measured rate to give you, so choose one yourself and track it. If you plan one rejected clip for every four, multiply the table by 1.25: weekly at 720p becomes $18.75, and daily becomes $140.63 (rounded to the cent).

Drafts and finals

A draft pass changes the shape of the spend. At 480p a 30 second draft is $1.875. If you draft every clip and finish about half at 1080p ($7.50), weekly cost is 4 x $1.875 + 2 x $7.50 = $22.50 against $30.00 for four straight 1080p renders. The saving depends on how many drafts you discard: if you finish every clip, drafting adds $7.50 to the month.

Balance and reserve

Sume bills against a workspace USD balance. At submit it reserves the billable amount, and the job's usage.cost field is the Sume billable amount after it finishes. Keep a balance above the largest batch you will submit at once; a submit without it fails with 402 insufficient_credits. For a daily clip at 1080p, that is at least $7.50 on the day, and for a batch of ten it is $75.00.

Which tier

Which resolution should a monthly budget assume? Use the lowest tier that survives the screen it will be seen on. A phone feed clip often needs less than a landscape lobby display. That is a judgment about your audience, not a Sume rule, so look at a 480p and a 720p sample on the real device before you commit to 1080p.

Two worked examples

Two worked examples show how the table is used. A local clinic posts one 30 second health tip a week at 720p: four clips, $15.00 a month, plus one retry allowance of $3.75 gives $18.75. An ecommerce team tests three hooks a week at 480p and finishes one winner at 1080p: 12 x $1.875 + 4 x $7.50 = $22.50 + $30.00 = $52.50 a month.

The same lens works for approval. Show the owner a single number per scenario, with the assumptions listed beside it: clips, resolution, retry allowance and whether drafts are kept. When the number moves, the assumption that moved is visible.

No volume discount to plan around

Seasonality changes the plan, not the method. In a busy month you submit more clips at the same price; the cost grows in a straight line with seconds. There is no tier discount in the pricing tables for Wan 3.0, so volume does not lower the per-second rate on Sume. The lever you have is resolution and the number of drafts you throw away.

Comparing with other rows

Compare at the same length with other Sume rows only after reading the catalog: Omni Flash 1.1 reaches 10 seconds per clip, so a 30 second film is three clips and a join; at 720p it is the same $0.125 a second. Seedance 2.5 reaches 30 seconds and is priced by tokens, so use its catalog quote for budgeting. The Sume docs list the limits in the Video Router page and the workspace limits in generation admission.
