Billing

• Billed per second at the output resolution rate: 480P, 720P, or 1080P (see the model square).
• Reference-video input seconds are billed at the same rate: billed seconds = output seconds + reference-video seconds. First/last frames, reference images, and reference audio are not billed.
• An unspecified metadata.resolution bills at the 1080P rate; always pass it explicitly.
• Failed tasks are not billed.
