Billing

Without reference videos you pay for output seconds: $0.10 at 480p, $0.20 at 720p. With reference videos, the input video seconds (at least 2) are added to the output length and billed at a lower rate: $0.065 at 480p, $0.13 at 720p. With duration: "auto" the quote assumes 15 seconds and the final charge uses the generated length.

  • Numbering follows array order within each type.

Limits

  • Reference video seconds count toward billing (minimum 2, up to 15).
