Pricing
Face Swap Video uses credits based on video duration and frame rate — credits are only charged for the frames that actually render:
The create response returns an estimated
credits_charged based on 30 FPS; the final amount is adjusted after the render completes if the actual frame rate differs. Check the completed job’s credits_charged for the exact cost.
