Describe the result you need
Ava plans the production from the brief. Optional segment hints give the director an ordered set of ideas. For recurring people or products, provide suitable references and describe their roles.
Audio and continuity
Choose native, voiceover, voice_clone, voice_design or none. A clone requires a reachable voice sample, and a designed voice requires a description. Model combinations can impose further constraints; handle structured validation errors instead of assuming every combination works.
4K and long-form movies
The director does not currently provide 4K output; a legacy 4k request is normalized to 1080p with a warning. The planned 10-second to 3-hour movie experience is separate from the current 5–300-second single-video API.
These are API option values, not a guarantee of every vendor capability. The current application and validation response are authoritative for available combinations.
