Price by resolution

Billable prices for 8 seconds at 9:16.

Arithmetic

At 720p: 463 - 303 = 160 cents, and 160 / 303 = 0.528, about 53 percent. At 480p: 215 - 141 = 74, and 74 / 141 = 52 percent. At 1080p: 1138 - 681 = 457, and 457 / 681 = 67 percent. The gap widens with resolution, so 2.5 is the expensive choice at 1080p.

When 2.5 is the only choice

At 15 seconds and 720p the catalog charges $8.67 for 2.5 and $5.67 for 2.0. Below 15 seconds both are available, so the choice is price against quality, which these tables do not measure. Above 15 seconds, 2.5 (and Wan 3.0) are the options for a text-to-video clip.

The Mini row is cheaper still: 15 s at 720p is $2.84. See the router docs for the full list.

• 2.5 range: 4 to 30 s; 2.0 range: 4 to 15 s.
• Both take 480p, 720p and 1080p and both take 1:1 to 21:9 ratios.
• The catalog lists no bitrate_mode for 2.5.

A batch view

For ten 8-second 720p clips the totals are $46.30 on Seedance 2.5 and $30.30 on 2.0, a $16.00 gap. For ten clips at 1080p the totals are $113.80 against $68.10, a gap of $45.70. These sums are 10 times the single-clip prices in the table.

A common plan is to draft on the cheaper model and re-render only the chosen takes on the dearer one. That is a workflow suggestion and not a claim about output quality: the catalog gives prices and ranges, not a ranking.

Other 2.0 family prices

The 2.0 family has three cheaper steps. For 8 seconds at 720p 9:16 the billable prices are $3.03 on Seedance 2.0, $2.42 on 2.0 Fast and $1.52 on 2.0 Mini. Against 2.5 at $4.63, that is 65, 52 and 33 percent of the price (303 / 463, 242 / 463, 152 / 463).

All of the 2.0 rows are limited to 15 seconds. If your ad needs a longer take, 2.5 and Wan 3.0 are the only prompt-driven rows that reach 30.

How to decide

Three questions settle it. Is the clip longer than 15 seconds? Then only 2.5 and Wan 3.0 qualify. Is the clip shipped at 1080p? Then the gap is 67 percent and 2.0 saves $4.57 per 8-second clip. Is the clip a draft? Then the cheaper row, or 480p, is enough, and a final render on 2.5 is the only spend that needs a reason.
