Limits & Constraints
Centralized operational constraints for predictable planning.
Core limits
- Maximum output duration: 60 seconds
- Output format: short-form social video constraints apply
- Captions and text should respect readable layout bounds
Input constraints
- Assets must be direct public media URLs (not HTML pages)
- Validate and render payloads must use top-level manifest fields
- Snake_case style keys are required where style objects are used
Practical guidance
- Keep layout coordinates in sane ranges to avoid clipping
- Use validate-first in reliable production workflows
- Prefer recipe paths unless custom timeline control is required
Retention and retrieval
- Output URL availability follows current storage retention policy
- Use job/webhook events for robust downstream automation
