Seedance 2.5 30-second clip as a whole Short: what it costs
One 30-second Seedance 2.5 clip at 720p is $17.334 on Sume. Compare with 8 and 15 seconds and with cheaper ways to fill 30 seconds.
The magichour.ai tracker (read 2026-10-07) reports Seedance 2.5 makes roughly 30-second clips in one pass. For a Short that sounds ideal: one generation, one Short. On Sume, the price decides whether it is.
Seedance 2.5, 9:16
| Length and size | Cost |
|---|---|
| 8 s, 480p | $2.149 |
| 8 s, 720p | $4.6224 |
| 15 s, 720p | $8.667 |
| 30 s, 720p | $17.334 |
| 8 s, 1080p | $11.3724 |
Other ways to fill 30 seconds
| Route | Cost |
|---|---|
| Seedance 2.5, one 30 s clip | $17.334 |
| Wan 3.0, one 30 s clip at $0.125 per second | $3.75 |
| Gemini Omni Flash, three 10 s clips at 720p | $3.75 |
| Seedance 2.5, four 8 s clips (32 s) | $18.4896 |
Verdict
A single 30 s clip is the most coherent route and the most expensive. If the Short is one continuous shot, the price may be fair. If it is cuts anyway, three 10 s Omni Flash clips or one Wan 3.0 clip cover the same time at about a fifth of the price. Run the same prompt on both at low cost before you commit.
