Submagic API – How Credits Are Used

Submagic API uses a credit-based system to measure and bill video processing usage. Credits are calculated based on the total duration of the video, measured in minutes.

How credit calculation works

• 1 credit = up to 1 minute of video
• Video duration is converted from seconds to minutes
• Any fraction of a minute is rounded up to the next full credit

This ensures predictable and transparent usage across all API requests.

Examples

• 30 seconds → 0.5 minutes → 1 credit
• 60 seconds (1 min) → 1 minute → 1 credit
• 61 seconds → 1.016 minutes → 2 credits
• 90 seconds (1.5 min) → 2 credits
• 120 seconds (2 min) → 2 credits
• 150 seconds (2.5 min) → 3 credits

Key things to keep in mind

• Credits are consumed per processed video
• Rounding always goes up, even for a few extra seconds
• Short clips still consume at least 1 credit
