Wan 3.0 Video Prime is billed per second of video processed, at a per-second rate set by the output resolution (480p, 720p or 1080p). Two things are counted:
- The video you generate: 2 to 30 seconds, or the length of the source clip when you edit a video with
duration: -1. - Every reference video you attach, at its full length (up to 15 seconds each). If you attach more than one, their lengths add up.
Text prompts, a first or last frame image, reference images and audio generation add no charge.
billed seconds = output duration + total reference video duration
cost = rate × billed seconds
Per-Second Rates
| Resolution | Rate |
|---|---|
| 480p | $0.085/s |
| 720p | $0.175/s |
| 1080p | $0.35/s |
Reference video seconds are charged at your output's rate, whatever the reference's own resolution or frame rate, so a lower-quality reference is not a cheaper one. A shorter one is.
Quick Cost Examples
| Mode | Resolution | Reference video | Output | Billed seconds | Cost |
|---|---|---|---|---|---|
| Text / image-to-video | 480p | — | 5s | 5 | $0.425 |
| Text / image-to-video | 720p | — | 5s | 5 | $0.875 |
| Text / image-to-video | 720p | — | 10s | 10 | $1.75 |
| Text / image-to-video | 1080p | — | 30s | 30 | $10.50 |
| With a reference video | 720p | 5s | 10s | 15 | $2.625 |
| With a reference video | 720p | 12s | 10s | 22 | $3.85 |
| With a reference video | 1080p | 12s | 10s | 22 | $7.70 |
Video edit (duration: -1) | 720p | 10s source clip | 10s | 20 | $3.50 |
Credit Holds vs. Your Final Charge
If you watch your balance during a generation, you may see an amount deducted that differs from what the clip ends up costing. That is expected:
- On request: Segmind places a temporary hold on credits, sized from this model's recent average cost. This is an estimate, not the price of your clip.
- On completion: the hold is settled at the actual cost of your request. If the hold was larger, the difference is returned to your balance right away; if it was smaller (common for long outputs or generations with reference videos), the remainder is deducted.
So the number to reconcile against the tables above is your balance after the request settles, not the momentary change while it runs.
Failed generations are not billed. If a request returns an error, the hold is rolled back in full and you are charged nothing.
Important Notes
- A reference video usually costs more than the output it drives: a 10-second output guided by a 12-second reference is billed as 22 seconds, not 10.
- Editing a clip bills the source and the result: editing a 10-second clip into a 10-second result is billed as 20 seconds.
- Audio is free: generating a soundtrack does not change the price.
- Aspect ratio does not affect the price: every ratio at a given resolution bills at the same rate.
- Exact lengths: output is billed in whole seconds of the video you receive, and reference videos at their measured length (for example, 11.71 seconds).
Cost Optimization Tips
- Trim reference videos to the motion you need: cutting a 12-second reference to 5 seconds saves 7 billed seconds ($1.225 at 720p) on every generation.
- Use reference images when you only need a character or a style: reference images add nothing to the bill; reference videos add their full length.
- 480p for drafts, 720p for delivery, 1080p for hero shots: each step up in resolution roughly doubles the per-second rate.
- Match duration to the shot: output cost is strictly per second, so request the length you need (2 to 30 seconds).
- Fix the seed to iterate: lock a seed and refine the prompt instead of re-rolling full-length renders.
Example Scenario
A creator producing 20 character-replacement clips a day at 720p, each a 10-second output driven by a 12-second reference video, is billed 22 seconds per clip: about $77.00/day. Trimming each reference to the 5 seconds that matter brings that to 15 seconds per clip, about $52.50/day.
