Video Pricing & Billing

How Pricing Works

Video generation is billed per second, with rates that vary by resolution. The key formula:

Total billed seconds = output video duration + reference video duration (if applicable)

For example, generating a 5-second 1080P video with a 10-second reference video:

• Output: 5 seconds
• Reference: 10 seconds
• Total billed: 15 seconds × $0.30/s = $4.50

Reference Video Billing

When you submit a reference video (for reference-to-video models), its duration is added to the billed total.

Example:

• You submit a 8-second reference video and request a 5-second output
• Total billed: 8 + 5 = 13 seconds
• At 720P: 13 × $0.15 = $1.95

Reference videos count toward duration limits

The total (reference + output) cannot exceed 30 seconds for Wan 3.0 models. Reference videos are capped at 15 seconds total across all clips.

Reference Images & Audio

Reference images and audio are not billed by duration — they’re included in the per-second output pricing.

When You’re Charged

Event	Billing action
Task submitted	Pre-authorized (held from balance)
Task completed	Final charge based on actual durations
Task failed	Charge refunded automatically

Checking Your Usage

1. Dashboard → Wallet → View transaction history
2. Each video generation shows as a separate entry with:
   • Model used
   • Duration billed
   • Amount charged
   • Timestamp

Auto-Duration (-1)

Some models support seconds: -1 for automatic duration selection. In this case:

• The model determines the output length
• You’re billed for the actual output duration (not a fixed amount)
• The pre-authorization uses the model’s maximum duration; the difference is refunded
