Billing & Credits

Understanding credit usage and billing.

Credits are based on the selected model and the run settings you choose. Video costs depend on duration, resolution, and run count.

Cost Drivers

  • Duration
  • Resolution multiplier
  • Model base cost
  • Number of runs

Resolution Multipliers

ResolutionMultiplier
480p0.8
720p1.0
1080p1.5
4k3.0

Minimum Cost

Each model has a minimum cost floor so short videos still cover compute usage.

Formula

rawCost = durationInSeconds x base_cost x resolutionMultiplier
perRunCredits = ceil(max(rawCost, min_cost))
finalCredits = ceil(perRunCredits x runs)

Worked Example

  • base_cost = 4
  • min_cost = 20
  • duration = 6s
  • resolution = 1080p (1.5)
  • runs = 2

raw = 6 x 4 x 1.5 = 36 → per run = 36 → total = 72 credits.
