The model determines the generation mode from your inputs. These modes are mutually exclusive - use either first-frame/last-frame OR reference inputs, not both.

"generate_audio": true,
"duration": 10,

Prompt Guide
Reference assets in your prompt using type + index: Image 1, Image 2, Video 1, Audio 1. The index is the position within that type in the arrays you provide. Do NOT use asset IDs in prompts.
Multimodal reference formula:
Image reference: "Refer to the [subject] from [Image N] to generate [scene], keeping [subject] consistent"
Video reference: "Refer to the [camera movement/action] from [Video N]"
