How many 30-second AI clips does $100 buy: Wan 3.0 vs Seedance 2.5

One hundred dollars of Sume credit buys 53 full 30-second Wan 3.0 clips at 480p, 26 at 720p and 13 at 1080p. On Seedance 2.5 the same budget buys 12, 5 and 2 clips. The gap comes from the price basis: Wan 3.0 bills per second of output, Seedance 2.5 bills per 1000 video tokens, and a 30 s Seedance clip is a large token count.

This post only counts whole clips, because a failed job is refunded and a clip cannot be bought in halves. It assumes text-to-video with no reference video, 16:9, and the catalog's default frame sizes.

The arithmetic, one resolution at a time

Sume bills the provider list price times 1.25, reserves it at submit and rounds each job up to the cent. Wan 3.0's list rates in the pricing tables are $0.05, $0.10 and $0.20 per second, which matches the Alibaba rates in the snapshot. At 480p that is 30 x $0.05 x 1.25 = $1.875, rounded up to $1.88. At 720p it is 30 x $0.10 x 1.25 = $3.75. At 1080p it is 30 x $0.20 x 1.25 = $7.50.

Seedance 2.5 tokens are ceil(width x height x seconds x 24 / 1024). At 720p 16:9 (1280 x 720) a 30 s clip is ceil(1280 x 720 x 30 x 24 / 1024) = 648,000 tokens. The 720p list rate is $0.0214 per 1000 tokens, so 648 x $0.0214 x 1.25 = $17.34. At 1080p the pricing table uses $0.0234 per 1000 tokens on 1,458,000 tokens, which gives $42.65.

What the leftover money means

Floor division leaves change: 53 x $1.88 = $99.64 at Wan 480p, and 2 x $42.65 = $85.30 at Seedance 1080p, so $14.70 stays unspent in that case. Use that change for 480p drafts of the next job rather than rounding the plan up.

A common plan is to draft on the cheap tier and finish once. A Wan 3.0 draft at 480p costs $1.88, so ten drafts plus one 1080p finish costs 10 x $1.88 + $7.50 = $26.30. Ten Seedance 2.5 drafts at 480p cost $80.70 before the final render is added.

A worked budget

Say a team wants 20 finished 30-second clips a month. At 720p on Wan 3.0 that is 20 x $3.75 = $75.00. The same 20 clips on Seedance 2.5 at 720p are 20 x $17.34 = $346.80, which is more than three of the $100 blocks above. If Seedance's reference handling or 1080p quality is the reason to choose it, the table shows what that choice costs per clip, and a per-clip decision is cheaper than a per-month one.

Where the numbers stop being valid

• Reference videos change Seedance 2.5 pricing, so a job that carries a reference clip will not match this table.
• Other aspect ratios change the Seedance frame size. 1:1 at 720p is 960 x 960, which has the same pixel count as 16:9, but 4:3 and 21:9 do not.
• The Wan 3.0 pricing code charges per second of video whether or not audio is generated, so the Wan counts hold with sound. The Seedance counts here assume no reference video.
• Alibaba's own page quotes $6.00 for a 30 s 1080p Wan clip and $1.50 for 480p. Those are the vendor list rates before Sume's 1.25 multiplier.
