LSF Seedance2.5 Production
Without video input, use the selected rate × ceil(final enhanced output seconds). With video input, use the video-reference rate × (measured input-video seconds + ceil(final enhanced output seconds)). Input seconds retain decimals and multiple references accumulate. No Production FPS multiplier applies.
Standard 1080p, 5.042 seconds output: $4.92 standard or $4.428 under the new-customer offer. With an additional 5-second reference: $5.412 standard or $4.8708 promotional.
Standalone Video Enhancement
Final charge uses the LSF second rate × FPS multiplier × ceil(actual output seconds). Bands: up to 30 FPS ×1, over 30 through 60 FPS ×2, over 60 through 120 FPS ×4. If fps is omitted, reserve at ×4 and reconcile using actual output FPS; omission does not force 120 FPS.
One final reconciliation
Reservations are estimates, not price caps. Repeated polling does not create a new charge, and accepted replays keep frozen pricing. Native Video and Audio use their own contracts and billing units.
