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
