Inputs (12)
| Name | Type | Default | Description |
|---|---|---|---|
| prompt | STRING | — | |
| quality | COMBO | 720p | Output resolution tier. Each tier is an exact canvas, not a label. |
| duration_seconds | INT | 66–20 | Envelope across all tiers. The admissible range narrows per tier; see tiers[].duration_seconds. |
| aspect_ratio | COMBO | 16:9 | 2 options: 16:9, 9:16 |
| audio_url | COMBO | A public URL, a data URI, or an asset id. | |
| enhance_prompt | BOOLEAN | false | Rewrite the prompt into this engine's native prompt grammar before rendering. Best effort: the prompt is sent unchanged if the rewrite is unavailable or would alter the requested direction. |
| generate_audio | BOOLEAN | true | LTX 2.5 Fast emits synchronized audio from the same pass; disabling it does not reduce cost. |
| image_url | COMBO | A public URL, a data URI, or an asset id. | |
| last_image_url | COMBO | A public URL, a data URI, or an asset id. | |
| seed | COMBO | 3 options: [object Object], [object Object], [object Object] | |
| generation_id | INT | 00–9007199254740991 | Keep fixed to reuse/resume this paid job. Increment for a fresh paid generation; independent of the model seed. |
| request_scope | STRING | Automatically assigned per node. Headless clients must supply a stable unique workflow/node ID. This is not a secret. |
