Credits & Plans
Understanding how credits work and plan limits for video generation.
Credit Costs
Credits are consumed when generating video content. Here's how credits are used:
| Operation | Cost | Notes |
|---|---|---|
| Scene generation | 1 credit per scene | AI generates an image for each scene |
| Audio generation | 1 credit per 1,000 characters | Text-to-speech for narration |
| Script generation | Free | Included at no extra cost |
| Video rendering | Free | Included at no extra cost |
Example
A video with 10 scenes and 2,500 characters of audio costs:
- Scene images: 10 credits
- Audio narration: 3 credits (2,500 chars Ãˇ 1,000 = 2.5, rounded up)
- Total: 13 credits
âšī¸ Credit Refunds
If image or audio generation fails (e.g., API timeout), credits are automatically refunded. You only pay for successful generations.
â ī¸ Insufficient Credits
If you try to create a video with insufficient credits, the API returns INSUFFICIENT_CREDITS (HTTP 402). See Errors for details.
Credits by Plan
| Plan | Monthly Credits | Approx. Videos |
|---|---|---|
| Starter | 120 | ~3-6 videos (20 scenes each) |
| Growth | 350 | ~8-15 videos (20 scenes each) |
| Scale | 950 | ~20-40 videos (20 scenes each) |
Approximate video count assumes 20 scenes per video with ~1,500 characters of audio per scene.
Storage & Retention by Plan
| Plan | Storage Cap | Video Retention |
|---|---|---|
| Starter | 500 MB | 7 days |
| Growth | 2 GB | 15 days |
| Scale | 5 GB | 30 days |
âšī¸ Auto-Cleanup
After a video completes, intermediate files (scene images, audio, debug images) are deleted immediately â only the final video and thumbnail are kept. Completed videos are auto-deleted after the retention period expires.
âšī¸ Manage Your Plan
Billing, subscription management, and usage tracking are available in the Sketchpen Dashboard. These are not available via the API.
