Credits per billable second, rounded to the nearest 5. Without video input, billable seconds are the output seconds; with a reference video they are max(4, input video seconds) + output seconds. The real channel costs 1.2x. duration "auto" reserves 30 seconds when submitted and refunds the difference once the clip is ready; credits_refunded shows it.
