Cost of 20 fifteen-second AI ads at per-minute video prices

Twenty 15-second ads are 300 seconds, or 5 minutes, of finished video. At the per-minute prices on Hedra's best-models page, read 2026-10-02, one pass costs $30.00 on Omni Flash at 1080p and $100.80 on Kling 3.0/O3 Pro at 1080p Pro, before any rerolls. Higgsfield's changelog says Ads Studio batches up to 20 ads per product, though that entry covers static ads; the same count in video is the case worked here.

These are Hedra's listed prices, not Sume's. Sume prices come from its catalog and receipts.

What does one pass cost at each price?

The totals are 5 minutes times Hedra's per-minute prices. Rows marked approximate carry that approximation.

Why plan for rerolls?

Not every clip is usable. If one in two needs a second try, the cost is not 20 clips but 30. Budget the expected number of generations, not the number of finished ads.

How do I cut the spend?

Draft at a lower tier and only render finals at the high one; a 480p-then-1080p loop on Sume shows the pattern. Check stills before video where you can.

How do I get Sume's number?

Read the model's pricing from GET /v1/videos/models, or use a dry_run on the paid MCP tool, which previews cost without submitting. Budget a 20-ad batch before you run it lists the controls.

A budget needs three numbers: the cost per minute, the minutes you need, and the reroll rate you expect. Start with a guess for the reroll rate from a ten-clip test, then update it after the first batch. If rerolls are common, spend the effort on better prompts and reference images before you spend on a higher tier.

Shorter clips change the math linearly: ten-second ads make the same 20-ad batch 200 seconds, or about 3.3 minutes, so each price above scales by two thirds. Cut length first if the budget is tight; a six-second hook often needs fewer retries than a fifteen-second story.
